Instructions

Cake

  • Preheat oven to 350°F and grease a 9x13 baking pan with nonstick cooking spray or line with parchment paper.
  • In the bowl of a stand mixer fitted with the paddle attachment cream together the softened butter, peanut butter and sugar until it starts to all stick together.
  • Then add the milk and vanilla extract and mix together well. The mixture will look a little clumpy and curdled but it's normal.

  • Bake cake in preheated oven on center rack for 20-25 minutes or until a toothpick inserted in the center comes out with only a few crumbs.
  • Let cake cool completely before frosting.
