This peanut butter sheet cake is packed with as much peanut butter as possible for a truly phenomenal taste and texture!

Ingredients

  • 1 1/2 cups granulated sugar
  • 1/2 cup brown sugar
  • 2 cups flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 1/2 cups milk divided
  • 1 cup creamy peanut butter
  • 1 cup butter
  • 2 teaspoons vanilla
  • 2 large eggs
  • 1 cup granulated sugar
  • 1/3 cup butter
  • 1/3 cup milk
  • 1/2 cup creamy peanut butter
  • 1/2 cup semi-sweet chocolate chips

Instructions

  1. Preheat oven to 400 degrees. Grease a rimmed half sheet pan.
  2. Add the sugars, flour, baking soda, and salt to the bowl of a stand mixer fitted with the paddle attachment.
  3. Add 1 cup of milk, peanut butter, and butter to a small sauce pan and bring to a boil, stirring often.
  4. Remove from heat and let set for 5 minutes to cool. Add to the bowl with the flour and sugar.
  5. Add the remaining 1/2 cup of milk, vanilla, and eggs to the mixer and turn to low speed. Mix until just combined.
  6. Spread cake batter into prepared baking sheet and bake for 15 minutes. Cool completely.
