Instructions

Preparation

  • Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan.
  • In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt.
  • Gently add the water along with vegetable oil, vinegar, and vanilla extract. Mix until well combined.
  • Pour the cake batter into the prepared pan, spreading it out evenly.
  • In a separate bowl, combine the creamy peanut butter, powdered sugar, softened butter, and vanilla extract for the filling.
  • Drop spoonfuls of the peanut butter mixture onto the cake batter and swirl gently with a knife.

Baking

  • Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
  • Allow the cake to cool in the pan.

Ganache Preparation

  • Prepare the ganache by heating the chocolate chips and heavy cream in a microwave-safe bowl in 30-second intervals, stirring until smooth.
  • Pour the ganache over the cooled cake and decorate with chopped peanuts, mini chocolate chips, and peanut butter cups.

Notes

Ensure ingredients are at room temperature for smoother batter. Do not overmix the batter; a few lumps are okay. Keep an eye on the cake while baking and cover with foil if it gets too dark.
