Peanut Butter Chocolate Cake

Peanut butter chocolate cake became my birthday cake of choice after a funny kitchen fail turned into something amazing I was originally trying to bake a simple chocolate layer cake but halfway through I realized I didn’t have enough butter for my usual frosting so I improvised with peanut butter and a little cream and what came out of that happy accident was a rich decadent combo that completely stole the show.

Ever since then this cake has been my go-to for celebrations and cravings alike because it’s bold indulgent and always a crowd-pleaser the layers are rich and moist the peanut butter frosting is creamy and just salty enough to balance the sweet and the chocolate ganache topping and candy bits on top make it feel like a party on a plate every single time.

Ingredients

Here’s what I use to build this showstopper cake. You can adjust the candy toppings to suit your favorites!

• All-purpose flour – Forms the structure of the chocolate cake.
• Cocoa powder – Adds deep chocolate flavor to the batter.
• Baking powder and baking soda – Helps the layers rise light and fluffy.
• Salt – Enhances all the rich and sweet flavors.
• Eggs – Provide structure and help the cake hold its shape.
• Sugar – Adds sweetness and contributes to moistness.
• Milk – Keeps the cake tender and soft.
• Vegetable oil – Adds moisture and helps the cake stay fresh.
• Vanilla extract – Enhances the chocolate flavor.
• Boiling water – Deepens the cocoa taste and keeps the batter smooth.
• Peanut butter – Used for the creamy frosting between layers.
• Butter – Blended with peanut butter for a fluffy, rich frosting.
• Powdered sugar – Sweetens and thickens the peanut butter frosting.
• Heavy cream – Adds smoothness and silkiness to the frosting.
• Chocolate chips – Melted into a ganache for the top layer.
• Mini peanut butter cups and candies – For topping and decoration.

Tools You’ll Need

• Mixing bowls – For preparing the batter and frosting separately.
• Electric mixer – Makes it easier to whip up the frosting until fluffy.
• Whisk – For blending dry ingredients and mixing batter smoothly.
• Measuring cups and spoons – For accurate ingredient ratios.
• Cake pans – To bake evenly-sized chocolate layers.
• Cooling racks – Essential for cooling cakes before frosting.
• Offset spatula – Helps spread frosting and ganache smoothly.
• Microwave-safe bowl – For melting the chocolate ganache.
• Cake stand or plate – To assemble and serve the cake beautifully.

Instructions

Step 1:

I preheat the oven to 350°F and grease three 8-inch round cake pans then I line the bottoms with parchment paper to ensure easy removal.

Step 2:

In a large bowl I whisk together flour cocoa powder baking powder baking soda and salt then I set that aside while I prep the wet ingredients.

Step 3:

In another bowl I beat the eggs with sugar oil milk and vanilla until smooth then I slowly stir in the dry ingredients and finally add the boiling water carefully mixing until the batter is thin and glossy.

Step 4:

I divide the batter evenly among the pans and bake them for 25 to 30 minutes until a toothpick comes out clean then I cool the cakes in the pans for 10 minutes before turning them onto wire racks to cool completely.

Step 5:

For the frosting I beat the peanut butter and softened butter together until creamy then I gradually mix in the powdered sugar and a bit of heavy cream until the texture is fluffy and easy to spread.

Step 6:

Once the cake layers are completely cool I stack them with generous scoops of peanut butter frosting between each layer spreading evenly with an offset spatula.

Step 7:

To make the ganache I melt chocolate chips with a splash of cream in the microwave then stir until smooth and glossy before pouring it over the top layer letting it drip naturally down the sides.

Step 8:

I finish the cake by decorating the top with chopped mini peanut butter cups and candies pressing them gently into the ganache while it’s still soft.

Tips

If you want to add crunch I recommend stirring crushed pretzels into the peanut butter frosting or using peanut butter M&Ms on top. I’ve also made this with a chocolate cake mix in a pinch and it still tastes amazing. Be sure to chill the cake slightly before slicing to keep the layers neat and even.

Ways to Serve

I love serving this peanut butter chocolate cake with a cold glass of milk or a scoop of vanilla ice cream on the side. It’s perfect for birthdays game day desserts or any time you want to impress a chocolate-loving crowd.

Frequently Asked Questions
