šŸ³ Instructions

šŸ„„ Step-by-Step Method

  1. Preheat your oven to 325Ā°F (163Ā°C). Lightly grease a 9×13-inch baking pan and set aside.
  2. In a large mixing bowl, cream together the softened butter and peanut butter until smooth and well incorporated.

  4. Add the yellow cake mix and water. Beat using an electric mixer on medium speed for 2 minutes or until smooth.
  5. Pour the batter into the prepared pan and spread evenly.

2. Bake the Cake

  1. Bake in the preheated oven for 40ā€“45 minutes, or until a toothpick inserted into the center comes out clean.
  2. Remove from oven and let the cake cool completely in the pan before frosting.

3. Make the Frosting

  1. In a large mixing bowl, cream the butter and peanut butter together until smooth and fluffy.
  2. Add the confectionersā€™ sugar, vanilla extract, and a pinch of salt (if using).
  3. Add 2 tablespoons of milk and beat until smooth. Add more milk, 1 tablespoon at a time, until the frosting reaches your desired fluffy and spreadable consistency.

4. Frost the Cake

  1. Once the cake is fully cooled, spread the peanut butter frosting evenly over the top using a spatula.
  2. For extra flair, top with crushed peanuts, chocolate chips, or a drizzle of melted chocolate (optional but heavenly).

šŸŗ A Brief History of Peanut Butter in Baking

Peanut butter became a pantry staple in the U.S. in the early 1900s. Originally developed as a protein-rich food for those unable to chew meat, it soon became a versatile ingredient in everything from sandwiches to baked goods. By the 1930s, recipes for peanut butter cookies, cakes, and bars began appearing in cookbooks, gaining popularity during the Great Depression when shelf-stable and affordable ingredients were essential.

This Peanut Butter Sheet Cake is a modern-day nod to those early recipesā€”a rich, dense, and satisfying dessert that uses humble ingredients to deliver big flavor.

šŸ§  Tips & Tricks

  • Don’t skip the softening: Let your butter and peanut butter come to room temperature for a creamier texture in both cake and frosting.
  • Frosting too thick? Add a splash more milk. Too thin? Add extra powdered sugar.
  • Make it extra: Add chopped peanuts, peanut butter cups, or even a swirl of jam for a PB&J twist.
