This cake has two layers of moist chocolate cake filled with a dark chocolate frosting. Then, the entire thing is frosted in a creamy peanut butter frosting that takes it over the top.
Make a peanut butter lover's birthday extra special by topping the cake with chopped Reese's peanut butter cups. It's a showstopper!

Key Ingredients
This frosted chocolate peanut butter cake recipe calls for basic ingredients you may already have in your kitchen.
- Butter - We prefer to use unsalted but can control the amount of salt in a recipe.
- Sugar - A mixture of granulated and brown sugar sweetens it.
- Eggs - Add structure and richness.
- All-Purpose flour. Spoon it into the measuring cup and level off with a knife.
- Dark Cocoa Powder - Hershey's special dark gives it a rich color and taste. Regular cocoa powder can be used, too.
- Baking Powder & Baking Soda - Provides the lift as it bakes.
- Milk & Coffee - Coffee enhances the chocolate flavor. You can use instant coffee or espresso powder in hot water if you don't have a coffee maker.
- Chocolate Chips - We prefer dark chips, but semisweet or milk chocolate is fine, too.
- Sour Cream - A full-fat sour cream adds creaminess and tanginess to the sweet frosting.
- Powdered Sugar - Sweetens and thickens the frostings.
- Peanut Butter - Use any creamy peanut butter that you like.
- Honey - The secret ingredient to our sweet peanut butter icing.
- Heavy Cream - Whipping the frosting creates a fluffy texture.
- Reese's Candies - Create a decadent and fun dessert with peanut butter cups.
How to Make Chocolate Peanut Butter Cake
If you want a delicious chocolate and peanut butter dessert, try this Reese's peanut butter cake. It's easy to make using a greased 9x13 pan.
Bake the Cake
- Beat the softened butter and sugar until light and fluffy. Add the eggs and vanilla, then mix again.
- Stir the flour, cocoa powder, salt, baking powder, and baking soda in a large mixing bowl.
- Alternate and add the dry ingredients and liquid to the wet ingredients.
- Pour the batter into the prepared pan, then bake until it pulls away from the pan.
- Let the chocolate cake cool in the pan for 15 minutes. Flip it out carefully on a wire rack and cool completely.
Make the Frostings
- Melt the chocolate chips and butter in a pan over low-medium heat, stirring constantly. Let it cool for 5 minutes. Mix in the sour cream until creamy.
- Stir together the powdered sugar and cocoa powder. Slowly beat it into the chocolate mixture, then set aside.
- Beat the butter and peanut butter in a large bowl until light and creamy. Add the honey, vanilla, and salt, then beat again at medium speed.
- Mix in the powdered sugar and heavy cream until creamy. Beat on high speed for 2-3 minutes until it is light and fluffy.
Assemble the Layers
- Cut the cake in half, making two 4 ½ x 6 ½ layers.
- Set aside ½ cup of the chocolate frosting. Spread the rest of the frosting on top of one layer, then place the other layer on top.
- Frost the cake with the peanut butter frosting. Use fork tines to add a fun decoration to the frosting before it develops a crust.
- Spoon the reserved chocolate frosting into a piping bag with icing tip 18. Pipe a border around the top edge.
- Add chopped peanut butter cups on the top and then press peanut butter cup halves around the bottom.
Storage Recommendations
After frosting, store the cake in an airtight container on the counter for up to 3 days. However, for longer storage, refrigerate leftovers.
You can also freeze slices for later by wrapping them several times in plastic wrap and storing them in a freezer-safe bag. Let them thaw in the fridge before serving.
Tips and Tricks
- Use cool coffee. I like to use leftover coffee from the pot in the morning. Let the coffee cool to room temperature first if it is still hot.
- Cool before frosting. A slightly warm cake can cause the frosting and layers to become slippery, making the cake unstable. It is best to let the cake cool completely before frosting.
- Level the top of the cake. A level surface is essential for even layering. Use a cake leveler or a long serrated knife.
- Add a crumb coat. Chill the cake in the fridge for 30 minutes. Then, apply a very thin layer of frosting around the outside of the cake using an offset spatula. Let it chill again, then add the rest of the frosting.
Variations
Of course, this cake is perfect exactly as it is. We love the mix of the two types of frosting and the heap of peanut butter cups on top! If you want to take it even more over the top, you can try these other ideas, too.
- Sheet Cake - The cake batter is usually baked in a 9x13, but you could also bake it in a greased half-sheet tray to make a sheet cake. You'll want to reduce the cooking time to avoid overbaking the cake, and then you'll need to decide which frostings you wish to use.
- Peanut Butter and Chocolate Swirl - Fill a piping bag with chocolate frosting on one side and peanut butter frosting on the other. Swirl on top of the cake.
- Chocolate Ganache - Heat 1 cup heavy cream and ½ cup dark chocolate chips in the microwave for 40 seconds, then stir until melted. Spread over the top of the cake, letting it drip down the sides.
- More Candy - Add Reese's Pieces around the edges of the cake or add chopped peanut butter cups between the layers.
FAQs
The coffee in the batter enhances the chocolate flavor. You will not taste the coffee in this recipe, but if you oppose it, use water instead. Be careful not to use hot coffee - let it cool to room temperature first.
Yes, the cake can be kept for a few days, so it is a great dessert to make ahead of time. Keep it tightly covered on the counter or in the refrigerator until needed.
You can also use two 9-inch round cake pans. The baking time will be similar but test with a toothpick test to ensure that they are fully cooked. Once the cake layers have cooled down, level them off to achieve a smooth finish.

Chrisi
Hi could I make this cake in 2 round tins
Jocelyn
I have not tried baking this in 2 round pans, but I think it would work if you used two 8 inch round pans. I'm also not sure on the baking time, so I would start checking the cakes at about 28 minutes and bake until a toothpick inserted in the center comes out with just a few crumbs.
