Ingredients
  

Cake

  • 1 ½ cups all-purpose flour
  • 4 tablespoons cocoa powder unsweetened
  • 1 cup sugar granulated
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon apple cider vinegar
  • 1 teaspoon pure vanilla extract
  • ¼ cup vegetable oil plus 1 tablespoon
  • 1 cup water

Peanut Butter Icing

  • 8 tablespoons unsalted butter softened ½ cup, 113 grams
  • 1 cup creamy peanut butter
  • 3 tablespoons half and half room temperature
  • 1 teaspoon pure vanilla extract
  • 2 cups powdered sugar

Instructions
 

  • Preheat the oven to 350°F. Lightly spray an 8x8 baking dish with nonstick cooking spray (all of the cake ingredients will be mixed in the baking dish).
  • Add the flour, cocoa powder, sugar, baking soda, and salt to the baking dish. Whisk the dry ingredients together until well combined.
  • Using a dry ladle or small measuring cup, make 2 small round impressions and 1 larger impression in the dry ingredients.
  • Pour the vinegar into 1 of the small impressions. Pour the vanilla into the 2nd small impression, and pour the vegetable oil into the largest impression. Pour the water over all of the ingredients.
  • Use a wooden spoon to stir all the ingredients together, making sure to get into the corners. Stir until all of the ingredients are well incorporated, and no dry streaks are visible.
  • Bake the cake on the middle rack for 30 to 35 minutes or until a knife inserted comes out clean. Allow the cake to cool completely before icing.
  • If using a stand mixer, or a medium-size mixing bowl and a handheld mixer on medium-high speed, cream the butter and creamy peanut butter until no streaks of butter are visible.
  • Lower the mixer speed to low and add the vanilla and half and half. Mix for another 30 seconds.
  • Keeping the mixer speed on low, slowly add the powdered sugar ½ cup at a time. Once all powdered sugar has been added, increase the mixer speed to medium and mix until the icing is smooth, about another 45 seconds to 1 minute.
  • Using a silicone spatula, frost the cake.
