Ingredients

Cakes

  • 1/2 cup light brown sugar
  • 1/2 cup sugar
  • 1/2 cup unsalted butter
  • 2 large eggs
  • 1/4 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 3 cups all purpose flour
  • 2/3 cup cocoa powder
  • 2 teaspoons baking soda
  • 1/2 teaspoon salt
  • 1 1/2 cups buttermilk

Filling

  • 1 cup milk
  • 1/4 cup all purpose flour
  • 1/2 cup unsalted butter softened
  • 1/2 cup smooth Peanut Butter
  • 1/4 teaspoon salt
  • 1 teaspoon vanilla extract
  • 1 cup powdered sugar

Instructions

Cakes

  • Preheat oven to 350 degrees. Line a large baking sheet with parchment paper or a silicone baking mat.
  • Use electric mixer to beat brown sugar, sugar, and butter until lightened and fluffy, about 3 minutes.
  • Mix in eggs, one at a time, scraping down sides as needed. Then, mix in vegetable oil and vanilla extract.
  • In a small bowl, whisk together flour, cocoa powder, baking soda and salt.
  • Alternate mixing in flour mixture and buttermilk in 3-4 additions each, beginning and ending with flour mixture.
  • On prepared baking sheet, drop about 3 tablespoons of batter in a circle shape. Make sure that edges of circles are at least 2 inches apart.
  • Bake for 10-12 minutes, or until tops of cakes have a cracked appearance and a toothpick inserted into the center one of the center cakes comes out with just a few crumbs.
  • Let cook on pan for 2-3 minutes before transferring to a cooling rack. Let cool completely before filling.

Filling

  • Heat milk in a saucepan over medium-low heat. Whisk in flour. Whisk continuously until the mixture turns in a thick paste that resembles glue.
  • Remove from heat and let cool completely.
  • Once mixture has cooled, use electric mix to mix in butter, peanut butter, salt and vanilla until smooth and creamy.
  • Mix in powdered sugar. Continue mixing until frosting is smooth and creamy, about 1-2 minutes.
  • Spread mixture evenly over one side of a cookie. Place a second cook on top of mixture.
