The title of the recipe

Ingredients

  • 2 1/4 cups all-purpose flour
  • 1 1/2 cups granulated sugar
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • 1 cup unsweetened cocoa powder
  • 1 cup whole milk, at room temperature
  • 2 large eggs
  • 1 teaspoon vanilla extract

Instructions

For the cake:

  1. Preheat the oven to 350°F (180°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper.
  2. In a medium bowl, whisk together flour, sugar, baking powder, and salt.
  3. In a large mixing bowl, combine cocoa powder and milk. Stir until smooth.
  4. Add the eggs one at a time, whisking well after each addition. Whisk in vanilla extract.
  5. Gradually add the dry ingredients to the chocolate mixture, whisking until just combined.
  6. Divide the batter evenly between the prepared pans and smooth the tops.
  7. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.

For the peanut butter mousse:

  1. In a small mixing bowl, combine 1/2 cup creamy peanut butter and 1 tablespoon confectioners' sugar.
  2. Whip until smooth and creamy.
  3. Add 1/4 cup heavy cream and whip until stiff peaks form.
  4. Stir in 1 teaspoon vanilla extract.

To assemble the cake:

  1. Place one of the cooled cakes on a serving plate or cake stand.
  2. Spread the peanut butter mousse over the top of the cake, leaving a 1-inch border around the edges.
  3. Top with the second cake and refrigerate for at least 30 minutes to allow the flavors to meld.

For the dark chocolate ganache:

  1. Melt 1 cup semisweet chocolate chips in a double boiler or in the microwave in 10-second increments, stirring between each interval until smooth.
  2. Stir in 2 tablespoons heavy cream and let cool to room temperature before spreading over the top of the cake.

Note: This recipe combines elements of apple baked crumble (crunchy topping) with key lime pie (peanut butter mousse).
