Ingredients

  • 1-½ cups all-purpose flour
  • 1 cup sugar
  • ¼ cup cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • cup vegetable oil
  • 1 tablespoon vinegar or lemon juice
  • 1 teaspoon vanilla
  • 1 cup water or brewed coffee

Chocolate Peanut Butter Frosting

  • ¾ cup peanut butter
  • ½ cup chocolate chips

Instructions

  • Preheat the oven to 350°F and grab an 8-inch square cake pan.
  • Sift or whisk the flour, sugar, cocoa, baking soda, and salt into the cake pan (or use a mixing bowl for easier mixing).
  • Make 3 wells or indentations in the flour mixture.
  • Pour the oil, vinegar, and vanilla into the separate wells.
  • Add the water or coffee then stir until combined.
  • Bake for 28 to 30 minutes or until a toothpick comes out clean.

For the Chocolate Peanut Butter Frosting

  • Combine the peanut butter and chocolate chips in a microwavable bowl.
  • Heat in 20-second intervals until the chocolate is melted. Stir well between intervals.
  • Spread on cooled cake.

Notes

  • It is much easier to mix all the ingredients in a bowl then transfer to the cake pan.
  • If you use the cake pan to mix the ingredients in then make sure you scrape the corners and edges of the pan. The dry ingredients can get trapped in the edges of the pan.
  • Make sure you preheat the oven before you mix the cake batter.
