For the cake

  • 1 ½ Cups all-purpose flour
  • ¼ Cup unsweetened cocoa powder
  • 1 Cup granulated sugar
  • 1 Teaspoon baking soda
  • ½ Teaspoon salt
  • 1 Teaspoon white vinegar
  • 1 Teaspoon pure vanilla extract
  • 5 Tablespoon vegetable oil
  • 1 Cup water

For the frosting

  • ½ Cup butter room temperature
  • 1 Cup creamy peanut butter room temperature
  • 3 Tablespoons warm water
  • 1 Teaspoon vanilla extract optional
  • 2 Cups powdered sugar sifted


For the cake

  • Preheat the oven to 350 F.
  • Add flour, cocoa powder, sugar, baking soda, and salt to a greased 8-inch square baking pan. Whisk until combined.
  • Make 3 depressions (or holes) in the dry ingredients – two small and one large. Pour the vinegar in one small depression, vanilla in the other small depression, and the vegetable oil in the third larger depression.
  • Pour the water over the pan. Mix with a wooden spoon until smooth. Make sure you get into the corners of the pan.
  • Bake for 35 minutes, or until a toothpick inserted comes out clean. Cool the cake completely on the rack.

For the frosting

  • Place vegetable shortening and peanut butter in a bowl and beat with an electric mixer until smooth and creamy.
  • Add two cups of powdered sugar and beat until well blended and it begins to thicken.
  • Add the vanilla and 1 tablespoon of water at a time.
  • Mix for 3 minutes or until it’s lighter and fluffy. If too thick, add a little more water and beat.
  • Spread frosting over the cooled cake.
