Timing
Making the Chocolate Peanut Butter Ganache Cake takes about 30 minutes for preparation, 30 minutes for baking, and 1 hour for cooling and assembling.
Instructions
Step 1: Bake the Chocolate Cake
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- Mix Dry Ingredients: In a large bowl, combine flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Add Wet Ingredients: Add eggs, milk, vegetable oil, and vanilla extract. Beat on medium speed for 2 minutes. Stir in the boiling water until well combined (the batter will be thin).
- Pour Batter: Divide the batter evenly between the prepared cake pans.
- Bake: Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
Step 2: Prepare the Peanut Butter Frosting
- Beat Butter and Peanut Butter: In a large mixing bowl, beat the softened butter and peanut butter together until creamy and smooth.
- Add Sugar and Cream: Gradually add powdered sugar, alternating with heavy cream, until the desired consistency is reached. Mix in vanilla extract and add salt to taste.
Step 3: Make the Chocolate Ganache
- Heat Cream: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer.
- Melt Chocolate: Remove from heat and add the chopped chocolate. Let it sit for a minute, then stir until smooth and glossy. Allow to cool slightly.
Step 4: Assemble the Cake
- Layer the Cake: Place one chocolate cake layer on a serving plate. Spread a generous amount of peanut butter frosting on top.
- Add Second Layer: Place the second cake layer on top and frost the top and sides of the entire cake with the remaining peanut butter frosting.
- Pour Ganache: Once the ganache has cooled slightly but is still pourable, pour it over the top of the cake, allowing it to drip down the sides.
Step 5: Serve
- Chill: Refrigerate the cake for about 30 minutes to set the ganache.
- Enjoy: Slice and serve this indulgent Chocolate Peanut Butter Ganache Cake!
