Happy Birthday!!!!!!!!!
I don’t know who you are, but I guarantee it’s at least one person’s birthday out there today.
I appreciate you! I really, really do. Thanks for making this blog a better place.
Oh wait, it’s not your birthday? I’m sorry. Want to see photos of the birthday cake I made yesterday anyway? It involves a lot of butter…and sugar…and other pencil skirt tightening things. But it’s really, really good! And sometime, I just know, you’ll need to make a triple layer cake and now you’ll know how! Genius.

I made these cake layers at night. I never bake at night. Mainly because it’s dark out…duh. However, some things just demand to be baked at night because when they are, the final product just turns out much better the next day. Such is the case with this cake! I mean, I’m sure you could bake and decorate the whole thing the day of, but if you have the time (heck, I had time!) you probably should make this cake in steps. Cake layers that have been refrigerated overnight are much easier to handle than cake layers right out of the oven.
The last thing you want is one of your lovely layers to break in half while icing. It’s such a mood kill. And I won’t even get into the time it caused me to smash an entire cake into the trash can at culinary school. It hurts too bad.
I smeared ganache in between my cake layers. Normally, I might do vanilla buttercream or even raspberry jam, but the friend that I was making this cake for loves chocolate so triple chocolate it was!
And let’s pause right now. If you’re reading this with disbelief in your eyes and a hanging jaw thinking “I could NEVER do ANYTHING like that!” think again my dear friend. You can! I know it sounds cliche, but if I can do it so can you. Things like this really take more practice than they do skill.
If it makes you feel better, I totally botched the middle layer of this cake by not pouring my batter evenly into my pans. Oops.
After you ganache the heck out of it, you need to apply a crumb coat! Think of a crumb coat like a base coat for your nails—it’s what gets them ready for the polish. Same thing goes with cake! You need to crumb coat a cake with a thin application of frosting so when you decorate, you will be crumb-free.
The best thing about crumb coats is that they don’t have to be perfect at all! Just smear it on there. Then stick it on the fridge and paint your nails. No, really!
Then, that turns into this!
I’m definitely not the world’s best decorator, and to be honest, I really don’t even like doing it that much. I’m scarred from one too many horrific frosting experiences in school. All you need though is a single star tip ($1.75 from Sur la Table) and either a plastic bag or a cloth pastry bag. Then, follow this easy tutorial!
You’ll be set in no time.
Triple Layer Chocolate Birthday Cake
serves 12
Ingredients:
for cake—
3 sticks butter, softened
1 3/4 cups sugar
1 3/4 cup boiling water
1 3/4 cup unsweetened cocoa powder
4 oz bittersweet chocolate, chopped
3 cups flour
1 vanilla bean (or 2 tsp vanilla extract), scraped
8 ounces reduced fat sour cream
5 eggs
2 1/2 tsp baking soda
1 tsp salt
for ganache—
8 ounces chocolate chips
2/3 cup milk (I used almond milk)
1 T maple syrup
for chocolate frosting—
2 sticks butter, softened
3 cups powdered sugar
1 vanilla bean (or 2 tsp vanilla extract)
1/2 cup reserved ganache
3 T cocoa powder
1/4 tsp salt
Directions:
To make the cakes: Preheat oven to 350 degrees. Butter and flour three nine-inch cake pans. Don’t just spray with cooking spray…it will not work.
Pour boiling water over cocoa powder and chopped chocolate. Mix well so there are no lumps and chocolate has melted. Set aside.
Cream together the butter and sugar until pale and fluffy. Add eggs one at a time, beating well after each addition. Add vanilla and beat again.
Whisk together the flour, baking soda and salt. Fold in the sour cream to the chocolate. Add this to the butter mixture alternately with the dry ingredients, mixing well after each addition. Batter might look like it’s “broken” but will come together in the end if you keep beating.
Divide batter amongst three pans evenly and bake cakes for 40 minutes, or until sides are beginning to pull away. Let cool then turn out cakes on wax paper and let cool completely. I recommend baking the cakes the night before you plan to serve it. The cakes are much easier to work with after they’ve been sitting in the fridge overnight (wrap each layer individually with foil or plastic wrap).
To make the ganache: Bring milk to a simmer on the stove. Pour over chocolate chips, add maple syrup and stir until incorporated and smooth. Let sit for 1 hour until thick. Place 1/2 cup ganache in a separate bowl or cup to use for frosting.
To make frosting: Cream together butter, powdered sugar and vanilla for 5 minutes on high speed. Add reserved ganache and cocoa powder and keep beating for another 8-10 minutes until very light, thick and fluffy. Set aside.
To assemble cake: Place one cake layer on a large plate (I like to do this on the plate I plan to serve on so I don’t have to attempt to move the cake later after it’s decorated). Spread an even layer of ganache all over the first layer then place the second layer on top. Repeat and top with the remaining layer. Refrigerate for 30 minutes.
Place about one cup of frosting on top of cake. Work down the sides of the cake with a small offset spatula (available at Sur la Table) to crumb-coat the cake. When the entire cake is covered with a very thin (!) layer of frosting, place back in the fridge for 10 minutes or so to firm up.
Now, place all remaining frosting on top of cake. You can always take extra off! Smooth frosting all over top of cake and down sides, scraping an extra back in the bowl. Place extra frosting in a plastic bag (or pastry bag) fitted with a large star tip. Pipe borders around the bottom and top of cake with extra frosting.
Serve at room temperature
**cake will keep fully decorated in the fridge overnight. If making cake layers the day before, be sure to cool each layer completely before wrapping tightly in tin foil or plastic wrap and placing in fridge.
Time:
~4 hours

It IS my birthday today! And this just made my day
It was my birthday yesterday too! Happy belated birthday to you!
After only reading the first line, my first thought was, “Who do I know that has a birthday coming up??”
I may just have to practice in the mean time!
Oh wow Jenna, this is beautiful! I haven’t made a birthday cake myself in wayyy too long, but my birthday is August 15th.. maybe I’ll just make this one for myself!
Comparing the crumb coat, to a base coat in nail polish, BRILLIANT! I’m diggin the hot blue frosting!
3 layers of chocolate? oh lordy.
Oh wow, you did a nice job on this one!! I just learned how to do the crumb coat. Love that!
Wow. chocolate cakes like these are staples at all my bdays and my relatives! love the pic with the batter and instyle mag
perfect reading material haha!
It like how you describe the ingredients as skirt tightening… HA!
They must have been tough on a girl in school, but you turned out AWESOME!!! Such a great cook, have you informed them of your awesomness? I would!
I love chocolate cake…I love chocolate…okay, I’m ready for a slice for breakie. Can that be arranged?!
That cake looks outrageous…. and my birthday is just a few weeks away;-)
Omg that cake looks amazing! I wish I could have a slice of that cake for breakfast right now!
Jenna it looks amazing! And yes, I was one of those people thinking…there’s just no way…but you’re right, practice makes perfect.
And practicing making chocolate cakes with frosting and piping them is the best kind of “have to practice” thing I think there ever was
man, i can’t wait til MY birthday! i’m totally making this bad boy for myself
Such a pretty cake!!! I love the blue!
I wish it was my birthday!
Wow, your layer cake is gorgeous.
I gonna try this soon
cake looks so good
you have a lucky friend – the cake looks delicious! love the unconventional blue too.
What a beautiful creation Jenna! Love the frosting colors!
My birthday is tomorrow and I have been trying to figure out what cake to make. Maybe this is it?
Layered cakes with frosting in the middle are well worth the time (and money if you end up buying it like I do). Oops
youre so awesome baking birthday cakes and it’s no ones bday!
i like you a lot!
Looks delicious. I love chocolate cake with ganache filling, perfect amount of indulgence. Then with a simple not so sweet buttercream, yum. Maybe this will be the boyfriend’s birthday cake this weekend!
I need a new friend with an upcoming birthday because all my family ones aren’t for months!
It’s MY birthday today! No, for real, it is! I just started following your blog the other day and I LOVE it! I made the roasted beet and goat cheese quinoa last week – delish! I can’t wait to try some of your other recipes!
PS – Can I get the cake delivered? No fun making your own birthday cake! Haha!
It is my sister’s birthday today — she turns 30! I’ll pretend you made this just for her
Oh my that looks amazing. I’m loving the InStyle in the background of that one picture (I work there – love to see it represented! haha)
OMG!!! its my birthday today! this has to be a sign!
thanks for creating a wonderful blog that is the first thing i read when i get to work (oops!)
Thanks Jenna!!!! It’s my birthday today!!! And that cake is just what I want
I appreciate you for bringing smiles to my face whenever I read your posts. Your blog is one-of-a-kind!
Me, Me, It’s my birthday! Might have to make this for myself when I get home! Love all your dishes! Keep ‘em coming!
Wow, it really is my birthday today! What a happy way to start the day. Although I usually have cheesecake on my birthday, this cake looks as if I might need to break tradition and try it instead. Thanks Jenna!
Also Happt Birthday Monica! Yay July 27th!
Whoops, Happy* Birthday
Hi Jenna!
Ahh it’s my birthday today!! I’m usually too shy to comment, but yours was the first blog I ever read and I absolutely adore it!
Xoxo,
Britt
my birthday is in 15 days (August 11). Close enough so I’m pretending this post is dedicated to me
Looks delish!!!
That brightened my morning!
what a gorgeous cake!
You are hilarious Jenna! Your posts always make me smile
I obsess over what birthday cake recipe to use when I need to bake one. I mean literally I go insane over choosing (I haven’t quite found one I am totally in love with) My boyfriends birthday is coming up in a couple months, and because your recipes always turn out ridiculously awesome I am going to bookmark this and make it for him! Thanks for taking the pressure off
BTW, I love how you mention that certain things just demand to be baked at night because they are just so much better the next day. So true! Words of wisdom haha Have a great Wednesday!
Jenna – It so happens to be my birthday today, so thank you for the nice little surprise this morning!
Love your blog – keep bloggin!
How funny! Today is my fiancee’s birthday! I was planning on making a cake for him so maybe I’ll try this one. Thanks!
Fab-u-lous! I’m working abroad for July and part of August. I love everything I’m seeing in London, but, boy do I miss baking. I can’t wait to make a cake – this one! – when I get home.
I want it to be my birthday NOW so that I can make this cake.
Or maybe I can use the excuse of practicing before then??
Yum! I love the pop of the blue.
You’ve definitely won my heart. I will always choose chocolate ganache on chocolate cake for my birthday cakes. I LOVE chocolate.
And a big happy birthday to all those who are celebrating today!
This would be among the best reward I would make for myself. I’ll have to set a higher standard before I can serve myself a slice of this (I’m trying to lose weight), but I am sure it’s more than worth it.
My birthday is friday!!! I love it. it’s not as cute as the cake my 6 year old son made for me. a white cake with Oreo’s on the side and sprinkles on the top. all his own ideas!! budding chef??
jenna–or anyone who wants to chime in– i’m going to have people over for a fresh Mex/southewestern style dinner tomorrow. i was thinking enchiladas? corn chowder? garden salsa? any suggestions on a menu (including dessert) & tested recipes would be most welcome. i’m lacking creativity.
Love enchiladas! Homemade guacamole too, for sure. And maybe a tres leche cake for dessert..or flan?
Taco bar would be fun – tortillas, taco shells, taco meat, cheese, pico, salsa, etc. Everyone can build their own tacos. Could also do fajitas this way. Could have some lettuce in there too in case some want to do taco/fajita salad. Of course chips and guac would be great. Black beans on the side. Sounds like a lot – but most of these things could be made ahead of time. For dessert – cinnamon ice cream?
I have a bake sale coming up, would this transfer to cupcakes well? Looks amazing!
Yeah! Thank you because today is my birthday! That cake looks Ah-Mazing!
Ooh gorgeous! And your pictures are still lovely, even if they were taken at night.
That definitely looks like my kind of cake!
If I pretend it’s my birthday can I drive up north and have a slice? That looks amazing!!!
Oh my! This cake is totally calling my name right now. Too bad I’m sitting at my desk for the next 6 hours. Maybe over the weekend.
This looks scrumptious!! One of my proudest baking moments was baking a layer cake for my dad.. It was from scratch, and he was CONVINCED it had to be a boxed mix because it was so good.
I want to be your friend and share this cake with you!
Wow !! This cake is amazing ! and I really LOVE colors !
That looks great! I LOVE baking, but cake decorating? Not so much. I have zero patience! You did an amazing job!
Mmmm I want to take a bath in that cake batter.
Or at the very least, lick it off a huge spoon.
Your fashion posts are cute & interesting but I’m pretty sure these recipe posts will always be my favorite! Thanks for the delicious recipe!
OMG this cake is outrageous and I love it! I really do wish I had an occasion to make this!
I am craving cake now! Thanks Jenna:)
My birthday is only a few days away! And this cake looks really tasty and sooo pretty!
It’s my brother’s birthday today
Gorgeous gorgeous cake!
Wow, that sounds like a job. Maybe I’ll make a one layer cake… I have like 4 birthdays coming up in August so I better be prepared to eat cake, cake, and more cake.
That cake looks delish by the way.
It could be my birthday…I’m willing to switch.
i want this for my birthday!
I love how you used blue icing! looks great (and tasty)
It’s my birthday! And I shall eat cake. Thank you!!
This looks fab!! I just made a 6 layer cake or my dads bday and making the layers the night before makes all the difference I think!
There’s no chocolate cake like a homemade chocolate cake. I really want to try and make this, but I must admit, I’m a little frightened. I can sometimes be an Amelia Bedelia in the kitchen.
I am a huge fan of your site and when I popped by this morning I was surprised to see a Birthday Cake…because today is my birthday. (7/27/77) I don’t usually comment, but just wanted to say Thank YOU! and keep up the great work on this blog. I love your creativity and every recipe I’ve tried on here has not disappointed. I especially LOVE the blackberry margaritas.
Happy Birthday!
I now need to bake a cake immediately! Thanks for the great recipe and instructions.
Haha I have had cake layers fall apart on me more than once… and always because I’m too eager and want to get them out of the pan right away. Someday I’ll learn patience
Beautiful cake! For some reason I think layer cakes are pretty much the most amazing thing on the planet. They rank up there with pie. That’s saying a lot.
It’s my birthday on Saturday! Perfect timing. I fully intend to make myself a ridiculously large layer cake. Totally normal.
it is my birthday, too! thanks!!!
xoxo
MY birthday is today! I have been thinking about lemon icebox pie for WEEKS after having some at Big Bob Gibson’s BBQ in Alabama. So I think I’m going to make one tonight. That’s what happens when you get older…you make your own birthday cake (or pie!).
My birthday is Saturday. I wish I could have a cake as pretty as this one. I absolutely love the pictures. Especially the one with the magazine and the very last one. You have become so professional with your pictures. I could go on your blog just to look at the pictures.
Yummm!! I just made my first layer cake this past weekend. I posted pics on my blog about my crazy experience. Note to self: if putting parchment paper under a cake to avoid getting frosting on the cake stand, don’t put the parchment too far under… or else you’ll never get it back out!!
Wellp now I need a birthday excuse to make it….or do I hehe
Hear that? That’s the sound of me drooling. This looks amazing! And thanks for the tip of making the layers a day ahead of time. I have broken layers many a time.

Hey, it’s my birthday today too, Jenna! Looks like there are lots of Leo babies that read your blog.
That cake looks amazing and can’t wait to try it!
It’s my 32nd birthday today but instead of cake I’m going to eat a huge grilled cheese sandwich here http://meltbarandgrilled.com/ If your ever in Cleveland it’s a must
My jeans got tighter as soon as I read, ’3 sticks butter…’
This cake is seriously to die for. I am hiding away this recipe until my fiance’s birthday in November. He will love it
Love from runningwithmascara.com and great post!
I have never met anyone with my birthday; I can’t believe there are so many of us out there! Happy Birthday everybody!
What I would do to have that cake on my birthday….
I actually need to make a cake this weekend and this is the first time I am hearing about a crumb coat. So, now I am looking very forward to giving it a shot!
Love a classic recipe like this — thanks!!
I need this cake in my face ASAP!
That icing looks simply divine. I love it when you can see the knife strokes.
Ugh, seriously? My husbands’ birthday is Saturday; he loves chocolate
Cake. I just got a donut pan and was going to make him donuts for his birthday…. But, how can I not try and make this??? I just wish it didn’t take 4 hours!!! I s’pose he’s worth it…. I guess I’m trying to really say thank you?! I’ll let you know how it turns out
I love the idea of just making a birthday cake for the sake of making a birthday cake. The post just made me giggle.
I’m reading this right before bed, and now I’m going to have dreams about cake! Thanks a lot, no really, this way I’ll wake up in a really good mood
and it’ll be Friday, *bonus*
Your friend is very lucky, happy birthday Jenna’s friend! I’m sure it will be one they won’t ever forget!
It was my son’s 2nd birthday on Weds. I was so busy making a cake and everything else I didn’t see this until now, but it still makes me smile! Maybe I’ll use it next year…
i’m making this cake right now for my sisters party tommorrow. after putting it in the pans i realized it doesn’t tell us when to add the sour cream?? help
janine
I’m so sorry! I updated the recipe with the instructions
I had the same issue when I made it this weekend, got it baked without the sour cream … and I couldn’t get my ganache to set. I was sad. But it was fun to try and my family was nice and ate some of it anyway. lol
Oh my gosh, Jenna. This cake is delicious.
I had trouble getting my ganache to thicken too, but since I used a vanilla butter cream with crushed oreo inside, we just added some oreo dust to compensate. Our frosting was over the top, and everyone agreed that it would be delicious with just ganache and dusted in powdered sugar.
Thank you!
