Chocolate Peanut Butter Oreo Cake
Chocolate Peanut Butter Oreo Cake: The classic combination of peanut butter and chocolate is taken to a whole new level with this chocolate cake topped with peanut butter frosting and crushed peanut butter cup Oreos!
I made you cake! And not just any cake.
I made you an out-of-control, triple layer chocolate cake with peanut butter frosting and peanut butter cup Oreos.
It’s completely over-the-top, but it’s also completely necessary, since there is absolutely nothing–nothing–like the flavors of peanut butter and chocolate.
There is also nothing like the flavors of peanut butter and Oreos.
Remember The Parent Trap? The remake with Lindsay Lohan before she had a psychotic meltdown? The one that’s coincidentally on TV now as I write this post? That movie not only introduced The La’s “There She Goes” to me, but also introduced me to the Babe Ruth of snacks: Peanut Butter Dipped Oreos.
That king of snacks is totally the inspiration behind this chocolate monstrosity, aka a chocolate obsession of a cake.
In the journey that is life, I have learned a few things about myself.
I’ve learned that I’m a sand snob. I’m that person at the beach who is constantly readjusting her towel so that she never has to lay down on uncomfortable shards of sand.
I’ve also learned that I’m a wet jeans snob. I absolutely loathe walking around with jeans that have been soaked at the ankle because you stepped into a giant puddle thanks to California not being built with proper water drainage in mind. On that note, I also don’t like wet shoes or socks.
I would pick coffee over tea any day, and would be devastated if Quaker ever discontinued Life (like Post did with Blueberry Morning–I’m still very bitter about that one). I’d pick a cinnamon roll over a donut, and firmly believe that Christmas triumphs all other holidays.
And lastly, among other things, I’ve learned that I love cake. I blame the cupcake craze on this one, which while we’re on the topic, why is there no cupcake emoji yet? There’s an eggplant but no cupcake.
Riddle me that one.
Much like this triple layer coconut cake, this triple layer chocolate cake is not too difficult to make. If layer cakes intimidate you, don’t worry! In the words of Tony Little, ” You can do iiiiiiiiit!”
But, really, you can do it. It’s easy as pie–or, um, cake?
The hardest part is trying to make the cake as symmetrical as possible, which can be a wee bit challenging. All you have to do is trim the cake layers to make sure each layer is relatively flat. Then, voila! With a layer of frosting between each, you have a giant, symmetrical cake.
It’s great. It’s a real showstopper. And it rivals the weight of a small child.

Chocolate Peanut Butter Oreo Cake
Ingredients
Cake
- 1 cup unsweetened cocoa powder or dark chocolate cocoa powder (I used dark, but regular works fine)
- 1 cup hot coffee (chocolate, espresso, or plain is best)
- 1/2 cup butter (softened)
- 1/4 + 2 Tbsp vegetable or canola oil
- 2 cups white sugar
- 1/2 cup brown sugar
- 4 large eggs
- 2 1/2 cups all purpose flour
- 2 Tbsp corn starch
- 2 tsp baking soda
- 1/2 tsp baking powder
- 3/4 tsp salt
- 1/2 tsp espresso powder (optional)
- 2 1/2 tsp vanilla extract
- 1/2 cup sour cream
- 1 cup milk
Frosting
- 12 Tbsp butter (softened)
- 1/2 cup peanut butter
- 4-5 cups powdered sugar
- 2-3 Tbsp heavy cream
- 1 tsp vanilla extract
- salt to taste
Oreos
- 8-9 Peanut Butter Cup Oreos (or regular, crushed)
- 3 Peanut Butter Cup Oreos (cut into fourths)
- 1 Peanut Butter Cup Oreo (whole)
Instructions
Cake
- Preheat oven to 350 degrees and grease 3 round 9" cake pans well.
- Mix cocoa with hot coffee, stirring until cocoa is dissolved (the mix will be thick). Set aside to cool.
- With a mixer, beat butter and oil together until well combined, about 1-2 minutes. Add in both brown and white sugar 1/2 cup at a time, mixing after each addition.
- Once combined, add eggs one at a time, beating after each addition.
- Add in coffee/cocoa mixture and mix well.
- In a separate bowl, sift together flour, corn starch, baking soda, baking powder, salt, and espresso powder. Set aside.
- Stir milk, sour cream, and vanilla extract together.
- With the mixer on low, alternately add flour mixture and milk mixture to the chocolate batter, beginning and ending with flour mixture.
- Mix the batter until just combined, then disperse batter evenly between 3 cake pans.
- Bake for 25-30 minutes, or until a cake tester comes out clean. Allow cakes to cool completely before removing from pans.
Frosting
- Combine butter and peanut butter and beat until light and fluffy. Slowly add in powdered sugar, beginning with 4 cups. Add 2 Tbsp heavy cream, vanilla, and a pinch of salt (to cut through the sweetness). If the frosting seems too thick, add in the last Tbsp of heavy cream. If the batter seems too thin, add in the last cup of powdered sugar, 1/4 cup at a time.
- Once the cakes have cooled, remove them from their pans. If needed, trim the cakes until they all are relatively flat and even in size.
- Place the bottom layer onto your cake plate and top with 1/2 cup of frosting. Sprinkle on 1/4 cup of crushed Oreos. Top with middle layer of cake, and repeat. Place on the top layer of cake, and frost the cake with remaining frosting*.
- Press remaining Oreo crumbs onto the outside of the cake (this will get messy). Place each quarter of Oreo around the outside of the cake evenly and place the final Oreo in the center of the cake.
- Refrigerate until ready to eat.
- Enjoy!

Meet Michelle
I’m a self-taught baker who truly believes it’s impossible to be upset when eating dessert. It’s my life’s goal to bake everyone happy!
If I’m not baking, I’m probably reading a good book with a cup a coffee in hand.
Welcome! I’m glad you’re here!
THE PARENT TRAP! Love. I actually also love the original with Haley Mills, but LL’s is superior because of the aforementioned oreo/PB combo. Also cake > pie any time, any place. I like coffee in the AM, and tea only when served the English way with milk and sugar, British Breakfast. Also cinnamon roll > donut. Christmas > everything else.
Michelle, this cake is SO gorgeous! And I absolutely love the flavors. I mean chocolate, pb and oreos?! Sign me up! Sounds delicious!
As if there’s no cupcake emoji! Who is running that app anyways?! I could go for a piece or three of this cake for my evening snack 🙂
OMG that sounds amazing! Peanut butter and oreos in the same cake? Love it. 🙂
This is such a show-stopper! Love the chocolate, peanut butter and Oreo combo! They sound like the perfect trifrecta of flavors! Just stunning!
I almost have no words for how incredible this cake looks! This is absolutely gorgeous and umm peanut butter and chocolate is the best!
This cake is fantastic! And any time you combine oreos, chocolate and peanut butter, you really can’t go wrong! Pinned!
Michelle – Your comment about the eggplant emoji made me giggle. I need this cake in my life. This is hands down the prettiest creation that I’ve seen all week. The flavors are probably just as delightful.
Looks great
Chocolate, peanut butter AND Oreos? Sign me up!
Oh em geeeeeee! Michelle! This cake has seriously got me speechless. Mostly because I just can’t stop drooling here. Anything with chocolate, pb, and oreos in the same sentence has just gotta be a winner! This cake clearly is. 🙂 Pinned!
Anytime you combine Oreos and cake it is a winner!! Looks delicious!
Whole new level is right, wow! This looks stunning and delicious and I want some for breakfast. I’m with you on the sand and jeans thing. The worst. Haha.

Hi Theresa! You can replace the hot coffee with hot water! 🙂
