Step-by-step instructions
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to ensure easy release.
- In a large bowl, combine the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt, whisking until mixed.
- Add the eggs, milk, vegetable oil, and vanilla extract to the dry mixture. Beat on medium speed for about 2 minutes, and then carefully stir in the boiling water—the batter will be thinner than usual.
- Divide the batter evenly between the prepared pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
- Allow the cakes to cool in the pans for 10 minutes before transferring them to wire racks to cool completely.
- For the peanut butter frosting, beat together the creamy peanut butter, softened butter, and powdered sugar until smooth. Add heavy cream and mix until fluffy.
- Once the cakes have cooled, spread peanut butter frosting between the layers, as well as on the top and sides.
- To make the ganache, heat the chocolate chips and cream in a saucepan over low heat until melted. Stir until smooth.
- Pour the ganache over the top of the cake, allowing it to drip down the sides for that magnificent finish.
- Slice, serve, and enjoy every decadent bite!
Best ways to enjoy it
This cake shines brightest when paired with a scoop of vanilla ice cream or a dollop of whipped cream. If you’re feeling extra adventurous, serve it with fresh berries to balance out the richness. Presentation matters too—consider using a cake stand to elevate your serving and let guests admire it before indulging!
Storage and reheating tips
To keep your Chocolate Peanut Butter Layer Cake fresh, store it in an airtight container at room temperature for up to 3 days. If you want to keep it longer, refrigerate for up to a week. Just remember to let it sit at room temperature for a bit before serving to enjoy its full flavor and texture. You can also freeze individual slices wrapped tightly in plastic wrap for up to three months.
Helpful cooking tips
- Ensure all your ingredients are at room temperature for better mixing.
- When baking, be careful not to overmix the batter once you’ve added the boiling water; this helps maintain a moist cake.
- Allow layers to cool completely before frosting; this prevents the frosting from melting.
Creative twists
Feel free to swap flavors around; you could try adding a hint of espresso to the chocolate batter for a mocha twist or incorporate crushed pretzels into the frosting for some delightful crunch. If you’re looking for a lighter version, consider using a sugar substitute or making the frosting with Greek yogurt for a health-conscious take.
