Ingredients

Scale

Cake Ingredients:

  • 2 cups all-purpose flour
  • 1.5 cups granulated sugar
  • 2 large eggs
  • 1 cup milk
  • 1/2 cup unsalted butter
  • 1/2 cup creamy peanut butter
  • 2 tsp baking powder
  • 1 tsp vanilla extract
  • 1/2 tsp salt

Frosting Ingredients:

  • 1 cup unsalted butter
  • 2 cups powdered sugar
  • 1/2 cup creamy peanut butter
  • 2 tbsp heavy cream
  • 1 tsp vanilla extract

Topping Ingredients:

  • 1.5 cups M&Ms peanut butter candies
  • 1/4 cup chopped peanuts (optional)
  • 2 tbsp chocolate drizzle

Instructions

  1. Preheat the oven to 350°F and thoroughly grease a 9×13-inch baking pan with butter or cooking spray.
  2. In a large mixing bowl, cream together butter, peanut butter, and granulated sugar until light and fluffy, approximately 3-4 minutes.
  3. Incorporate eggs one at a time, mixing thoroughly after each addition, then blend in vanilla extract.
  4. Sift together flour, baking powder, and salt in a separate bowl, creating a uniform dry mixture.
  5. Gradually alternate adding dry ingredients and milk to the wet mixture, mixing until a smooth, consistent batter forms without overmixing.
  6. Pour the batter evenly into the prepared pan, ensuring an smooth surface with a spatula.
  7. Bake for 25-30 minutes, or until a toothpick inserted into the center emerges clean and the cake is golden brown.
  8. Remove from oven and allow the cake to cool completely in the pan for about 1 hour.
  9. For the frosting, whip butter and peanut butter together until creamy and well combined.
  10. Gradually fold in powdered sugar, heavy cream, and vanilla extract, beating until the frosting is light and spreadable.
  11. Once the cake has cooled, spread the frosting evenly across the entire surface.
  12. Decoratively sprinkle M&Ms peanut butter candies over the frosted cake, creating an even coverage.
  13. Optional: Garnish with chopped peanuts and drizzle melted chocolate over the top for added texture and visual appeal.
  14. Refrigerate for 15-20 minutes to set the frosting before slicing and serving.

Notes

  • Soften butter and peanut butter at room temperature for easier mixing and smoother cake texture.
  • Avoid overmixing the batter to prevent a dense, tough cake; mix just until ingredients are combined.
  • Use room temperature eggs to ensure even incorporation and better cake rise.
  • Gluten-free option: Replace all-purpose flour with a 1:1 gluten-free baking blend for celiac-friendly version.
  • Check cake doneness early to prevent overbaking, which can lead to dry results.
  • Chill the cake briefly before frosting to create cleaner, more precise decorative edges.
  • Store leftover cake in an airtight container in the refrigerator for up to 4-5 days.
  • For intense peanut butter flavor, use natural peanut butter with no added sugar or oils.
