Ingredients

Peanut Butter Cake

  • 3/4 cup (12 tablespoons) unsalted butter, room temperature
  • 1 cup chunky peanut butter
  • 1 tsp. vanilla extract
  • 4 large eggs, room temperature
  • 3 cups brown sugar
  • 2 1/2 cups all purpose flour
  • 1 tsp. baking powder
  • 1 tsp. baking soda
  • 1/2 tsp. salt
  • 1 cup buttermilk

Butterscotch Topping

  • 1/2 c chunky peanut butter
  • 1 1/2 sticks butter
  • 1 1/2 bags 11 oz butterscotch chips

Instructions

Peanut Butter Cake

  • In the bowl of a stand mixer with paddle attachment, cream together room temperature butter, peanut butter, vanilla, eggs (one at a time) and brown sugar in mixer. 
  • In a separate bowl, sift together flour, baking powder, baking soda, and salt.
  • Add the flour mixture to the sugar mixture, alternating with buttermilk. As in, add 1/3 flour mixture then 1/2 cup of buttermilk, another 1/3 of the flour mixture, remaining buttermilk, then remaining flour.
  • Bake in two prepared 9-inch round cake pans at 350°F for 25-35 minutes.

Butterscotch Topping

  • Melt butter and peanut butter in medium saucepan over medium-low heat. 
  • Once they are fully melted and combined, add in butterscotch chips. Stir continually until mostly melted. There will be chunks in the bottom of the pan, this is ok.
