Ingredients

Scale
  • 1/2 cup (112g) unsalted butter, room temperature
  • 3/4 cups (155g) sugar
  • 3/4 cup (108g) brown sugar, loosely packed
  • 3/4 cup (210g) peanut butter
  • 1/2 cup (115g) sour cream
  • 2 tsp vanilla extract
  • 3 large eggs
  • 2 1/2 cups (325g) all-purpose flour
  • 2 3/4 tsp baking powder
  • 1/2 tsp salt
  • 1/2 cup (120ml) milk
  • 1/4 cup (60ml) water
  • 2 cups (448g) salted butter, room temperature
  • 1 1/4 cups (350g) peanut butter
  • 9 cups (1035g) powdered sugar
  • 67 tbsp (90–105ml) water or milk
  • 10 oz peanut butter chips
  • 6 oz peanut butter chips
  • 1/2 cup (120ml) heavy whipping cream

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a mixing bowl, beat together the unsalted butter, sugar, brown sugar, and peanut butter until creamy. Add in the sour cream, vanilla extract, and eggs one at a time. Mix until fully combined.
  3. In another bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this mixture to the wet ingredients while alternating with milk and water. Start and end with dry ingredients. Stir until just combined.
  4. Divide the batter evenly between the prepared cake pans. Bake in preheated oven for about 23 minutes or until a toothpick inserted in the center comes out clean. Let cool in pans for 10 minutes before transferring to a cooling rack.
  5. In a large bowl, beat together salted butter and peanut butter until smooth. Gradually add powdered sugar while mixing on low speed. Adjust consistency with water or milk as needed.
  6. Once cooled, place one layer on a serving plate. Spread frosting over the top of the first layer before adding the second layer. Cover the entire cake with remaining frosting.
  7. Melt half of the peanut butter chips in a microwave-safe bowl until smooth. Drizzle over the frosted cake. Sprinkle remaining chips on top for decoration.
