Ingredients

Scale

Cake Ingredients

  • 2 ½ cups all-purpose flour
  • 2 ½ teaspoons baking powder
  • 1 cup granulated sugar
  • 1 cup creamy peanut butter
  • 3 large eggs
  • 1 cup milk (room temperature)
  • 1 teaspoon vanilla extract
  • 1 cup M&M’s candies (plus extra for topping)

Frosting Ingredients

  • ½ cup butter (softened)
  • ½ cup creamy peanut butter
  • 2 ½ cups powdered sugar
  • 2 tablespoons milk (adjust as needed for consistency)

Instructions

  1. Prepare the Oven and Pans: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans to prevent sticking and ensure easy release after baking.
  2. Mix the Dry Ingredients: In a medium bowl, sift together the all-purpose flour and baking powder. This ensures an even rise and a light texture for the cake.
  3. Combine Wet Ingredients: In a large bowl, beat the peanut butter and granulated sugar until creamy. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract. Gradually add milk to achieve a smooth batter consistency.
  4. Blend Dry and Wet Ingredients: Slowly incorporate the sifted flour mixture into the wet ingredients, stirring gently until just combined. Avoid overmixing to keep the cake tender.
  5. Add the M&M’s: Fold in 1 cup of M&M’s candies gently into the batter, reserving some to sprinkle on top before baking.
  6. Bake the Cake: Divide the batter evenly between the prepared pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Allow cakes to cool completely before frosting.
  7. Prepare the Frosting: Beat softened butter and peanut butter together until smooth. Gradually add powdered sugar and a splash of milk, whipping until fluffy and spreadable.
  8. Assemble the Cake: Place one cake layer on a serving plate, spread a thick layer of peanut butter frosting, then top with the second layer. Cover the entire cake with frosting and decorate with the remaining M&M’s candies.

Notes

  • Use room temperature butter, eggs, and milk for a smooth batter and even baking.
  • Fold M&M’s gently into the batter to prevent melting or color bleeding.
  • Remove the cake promptly once it passes the toothpick test to keep it moist.
  • Let cakes cool completely and chill slightly before frosting to prevent melting.
  • Choose creamy, natural peanut butter for the best flavor and texture.
  • Store leftovers tightly covered at room temperature up to 3 days or refrigerate up to a week.
  • Freeze wrapped cake for up to 2 months; thaw overnight in the fridge before serving.
  • Warm slices gently in the microwave for 10-15 seconds to enhance aroma and soften frosting.
