Ingredients

Chocolate Cake

• 1 cup flour
• 1 cup sugar
• 1/4 cup + 2 tbsp Hershey’s Special Dark Cocoa powder
• 1 tsp baking soda
• 1/2 tsp salt
• 1 large egg
• 1/2 cup buttermilk
• 1/2 cup vegetable oil
• 3/4 tsp vanilla
• 1/2 cup boiling water

Peanut Butter Truffle

• 20 oz peanut butter chips
• 2 1/4 cups heavy cream
• 1 cup (8 oz) mascarpone cheese

Chocolate Icing

• 1/4 cup shortening
• 1/4 cup butter
• 2 cups powdered sugar
• 1/4 cup Hershey’s Special Dark Cocoa powder
• 2–3 tsp water

Instructions

Preparing the Chocolate Cake

1. Preheat your oven to 300°F (150°C). Prepare a 9-inch cake pan with a parchment paper circle on the bottom and grease the sides. For best results, use a leakproof 9-inch springform pan.
2. In a large mixing bowl, whisk together the dry ingredients: flour, sugar, cocoa powder, baking soda, and salt.
3. Add the egg, buttermilk, and vegetable oil to the dry mixture and stir until well combined.
4. Mix the vanilla extract into the boiling water, then slowly add this to the batter. Stir until the mixture is smooth and fully incorporated.
5. Pour the batter into the prepared cake pan. Bake for 33–35 minutes, or until a toothpick inserted into the center comes out with just a few crumbs.
6. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.

Crafting the Peanut Butter Truffle Layer

7. Place the peanut butter chips into a medium-sized mixing bowl.
8. Heat the heavy cream in the microwave until it reaches a boil, then pour it over the peanut butter chips.
9. Cover the bowl with plastic wrap and let it sit for 5–7 minutes.
10. Whisk the mixture until smooth, then cover it again and refrigerate for 45 minutes to 1 hour. It should thicken but remain stirrable.
11. Stir the mascarpone cheese into the mixture until smooth and creamy.

Assembling the Cake

12. Once the cake is completely cool, use a serrated knife to level the top by removing any dome that may have formed.
13. Place the cake back into the springform pan, lining the sides with parchment paper to extend above the pan’s edge.
14. Pour the peanut butter truffle mixture over the cake and spread it evenly. Ensure the parchment paper is high enough to support the filling if it rises above the pan’s edge.
15. Refrigerate the cake for 3–4 hours, or until the truffle layer is firm.

Making the Chocolate Icing

16. In a mixing bowl, beat the shortening and butter together until smooth.
17. Add the powdered sugar, cocoa powder, and 1 tsp of water. Mix until smooth. Adjust the consistency with more water as needed.
18. Transfer the icing to a piping bag and decorate the edges of the cake. Optionally, drizzle with chocolate sauce for an extra touch of elegance.

Serving

19. Refrigerate the assembled cake until ready to serve. Allow it to sit at room temperature for 15–20 minutes before slicing, letting the truffle layer soften slightly for the best texture.

Flavors and Textures

The rich, dark chocolate cake is balanced perfectly by the creamy peanut butter truffle. The mascarpone in the truffle layer adds a subtle tang, enhancing the peanut butter’s nuttiness. Meanwhile, the chocolate icing ties the layers together with its sweet and slightly bitter notes. Together, these elements create a harmonious balance of flavors that’s indulgent without being overwhelming.

Tips and Variations

• Ingredient Substitutions:
  • Use semi-sweet chocolate chips if peanut butter chips are unavailable; mix with 2 tbsp of smooth peanut butter for similar results.
  • Replace mascarpone with cream cheese for a tangier filling.
  • Swap buttermilk with a mixture of 1/2 cup milk and 1/2 tbsp lemon juice (let sit for 5 minutes).
• Decorating Ideas:
  • Top with crushed peanuts for a crunchy contrast.
  • Add chocolate curls or sprinkles for a festive touch.
• Serving Suggestions:
  • Pair with a scoop of vanilla ice cream for a classic combo.
  • Serve alongside a cup of hot coffee or cold milk.
