Instructions

Preparation

  • Preheat your oven to 350°F (175°C) and grease your 9-inch round cake pan.

  • Add the water, vegetable oil, vinegar, and vanilla extract; mix until you achieve a smooth batter.

Baking the Cake

  • In a separate bowl, combine peanut butter, powdered sugar, softened butter, and vanilla extract for the filling.
  • Drop spoonfuls of the peanut butter mixture onto the cake batter. Use a knife to gently swirl the peanut butter into the batter.
  • Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
