  • 2 cup light brown sugar packed
  • 1 cup creamy peanut butter for the batter
  • ½ cup unsalted butter softened, for the batter
  • 1 tsp baking powder
  • ½ tsp baking soda
  • 1 cup milk plus 1/4 cup more, for the batter
  • 2 tsp vanilla extract

Instructions
 

Cooking

  • Prep. Heat the oven to 350 degrees F and grease and flour two 9 inch round pans.
  • Batter. Cream the butter and brown sugar, mix in the peanut butter, then beat in the eggs and vanilla.
  • Combine. Stir the flour, baking powder, and baking soda together and fold into the batter in alternating batches with the milk.
  • Bake. Divide between the pans and bake for 25 to 30 minutes, then cool in the pans for 10 minutes and turn out onto racks.
  • Frost. Beat the peanut butter and butter with the powdered sugar and milk until spreadable, then frost the cooled layers.

Notes

Substitutions: Swap crunchy peanut butter for part of the creamy for extra texture.
Tips: Cool the layers fully before frosting so the frosting stays thick.
Storage: Keep covered at room temperature for up to three days or in the refrigerator for up to a week.
Nutrition does not include the optional chopped peanuts or chocolate shavings.
