Ingredients:

For the Chocolate Cake:

2 cups all-purpose flour
2 cups granulated sugar
¾ cup unsweetened cocoa powder
1 ½ teaspoons baking powder
1 ½ teaspoons baking soda
1 teaspoon salt
1 cup buttermilk
½ cup vegetable oil
2 large eggs
2 teaspoons vanilla extract
1 cup boiling water

For the Peanut Butter Filling:

1 cup (2 sticks) unsalted butter, softened
3 cups powdered sugar
1 cup creamy peanut butter
¼ cup milk
1 teaspoon vanilla extract

For the Chocolate Ganache:

1 cup heavy cream
12 ounces semi-sweet chocolate chips
2 tablespoons unsalted butter

Optional Garnish:

Chopped peanuts
Mini peanut butter cups
Chocolate shavings

Preparing the Chocolate Cake:

Preheat and Prep: First things first, preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. I like to use baking spray with flour already in it – it makes life so much easier! You can also line the bottoms with parchment paper circles for extra insurance against sticking.
Combine Dry Ingredients: In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Make sure everything is well combined so you don't get pockets of baking powder in your cake.
Add Wet Ingredients: In a separate bowl, whisk together the buttermilk, oil, eggs, and vanilla extract.
Combine Wet and Dry: Gradually add the wet ingredients to the dry ingredients, mixing on low speed until just combined. Be careful not to overmix! Overmixing can lead to a tough cake.
Add Boiling Water: Slowly pour in the boiling water while mixing on low speed. The batter will be very thin – don't worry, that's normal! The hot water helps to bloom the cocoa powder and creates a super moist cake.
Divide and Bake: Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
Cool Completely: Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely. This is crucial! Trying to frost a warm cake is a recipe for disaster.

Making the Peanut Butter Filling:

Cream the Butter: In a large bowl (or the bowl of your stand mixer), beat the softened butter until it's light and fluffy. This usually takes about 2-3 minutes.
Add Powdered Sugar: Gradually add the powdered sugar, one cup at a time, beating on low speed until combined. Be careful not to create a powdered sugar cloud!
Mix in Peanut Butter: Add the peanut butter and beat until well combined.
Add Milk and Vanilla: Pour in the milk and vanilla extract and beat until the frosting is smooth and creamy. If the frosting is too thick, add a little more milk, one tablespoon at a time, until you reach your desired consistency.

Preparing the Chocolate Ganache:

Heat the Cream: Place the heavy cream in a microwave-safe bowl and heat in 30-second intervals, stirring in between, until it's just simmering. You can also do this in a saucepan over medium heat. Just watch it carefully so it doesn't boil over!
Pour Over Chocolate: Pour the hot cream over the chocolate chips in a heat-proof bowl. Let it sit for about a minute to allow the heat to melt the chocolate.
Stir Until Smooth: Gently stir the mixture until the chocolate is completely melted and the ganache is smooth and glossy.
Add Butter: Stir in the butter until it's melted and incorporated into the ganache. This will give the ganache a beautiful shine.
Let it Cool Slightly: Let the ganache cool slightly before pouring it over the cake. This will help it thicken up a bit and prevent it from running off the sides completely.

Assembling the Cake:

Level the Cakes: Once the cakes are completely cool, use a serrated knife to level the tops if necessary. This will ensure that your cake is nice and even.
Place First Layer: Place one cake layer on a serving plate or cake stand.
Add Peanut Butter Filling: Spread the peanut butter filling evenly over the first cake layer. I like to use an offset spatula for this.
Place Second Layer: Carefully place the second cake layer on top of the filling.
Pour Ganache: Pour the slightly cooled chocolate ganache over the top of the cake, allowing it to drip down the sides. You can use a spatula to help spread the ganache evenly.
Garnish (Optional): If desired, garnish the cake with chopped peanuts, mini peanut butter cups, or chocolate shavings. Get creative!
Chill (Optional): For best results, chill the cake in the refrigerator for at least 30 minutes before serving. This will allow the ganache to set up and the flavors to meld together.
Serve and Enjoy!: Slice and serve your delicious Chocolate Peanut Butter Cake! This cake is rich and decadent, so a small slice goes a long way. Enjoy!

A drizzle of hot fudge sauce wouldn't hurt either, adding another layer of chocolatey richness. But the fun doesn't stop there! There are so many ways to customize this recipe to your liking. If you're a fan of dark chocolate, use a dark chocolate cocoa powder for a more intense flavor. For a lighter, fluffier frosting, whip the peanut butter with a little bit of heavy cream before adding the powdered sugar. Want to add some crunch? Sprinkle chopped peanuts or peanut brittle on top of the frosting. Or, for a more sophisticated touch, try adding a layer of chocolate ganache between the cake layers. If you're looking for a smaller portion, this recipe can easily be adapted to cupcakes. Simply reduce the baking time and adjust the frosting accordingly. Chocolate Peanut Butter Cupcakes are perfect for parties, potlucks, or a simple weeknight treat. Another variation I love is adding a swirl of peanut butter to the cake batter before baking. This creates a beautiful marbled effect and adds even more peanut butter flavor to every bite. You could also add chocolate chips to the batter for an extra burst of chocolate.
