Instructions
Preheat Oven
- Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
Mix Dry Ingredients
- In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
Combine Wet Ingredients
- In another bowl, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract. Gradually add this wet mixture into the dry ingredients, mixing until smooth.
Add Boiling Water
- Carefully stir in the boiling water until the batter is well combined.
Bake the Cake
- Pour the batter into your prepared cake pan. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack.
Prepare the Peanut Butter Filling
- While the cake cools, beat together the creamy peanut butter, powdered sugar, softened butter, and heavy cream until smooth and creamy.
Spread Peanut Butter Filling
- Once the cake is cool, evenly spread the peanut butter filling over the top of the cake.
Make the Chocolate Ganache
- In a small saucepan, heat the heavy cream until it begins to simmer. Remove from heat and stir in the chocolate chips and butter until smooth and glossy.
Top with Ganache
- Pour the ganache over the peanut butter filling, spreading it evenly. Allow the ganache to set before slicing and serving.
Notes
Use room temperature ingredients for the best texture. Don’t overmix to ensure a light cake texture. If your ganache is too warm, chill it slightly before pouring over the cake.
