M&M Cupcakes

M&M Candy Bar Cupcake Recipe

Author Jennifer Tammy


  • 1 box chocolate cake mix
  • PLUS listed ingredients on cake mix box
  • 12 chocolate squares
  • 2-12 oz bags M&Ms
  • 1 cup butter
  • 1 cup cocoa
  • 3-5 cups icing sugar
  • 2-3 Tablespoons cream
  • 1 teaspoon vanilla


  1. Preheat oven to 325F.
  2. Prepare the cake mix according to box directions. Portion out 1/3 cup of batter into each liner of a lined muffin tray.
  3. When the cupcakes are a bit puffy but not completely baked, about the 12 minute mark, remove from the oven and add a square of chocolate to the top of each cupcake. It will sink into the middle of the cupcake and melt into a glorious chocolate surprise. Bake for the remaining time according to the box directions, and remove to a cooling rack to cool when an inserted toothpick comes out clean (steering clear of the center as the melted chocolate will skew things).
  4. Meanwhile, prepare your chocolate buttercream frosting by blending the butter, cocoa, icing sugar, vanilla, and using the cream to adjust for your desired consistency.
  5. I used an offset spatula to add a "base layer" of frosting, added a scoop of M&Ms, and then used a piping bag (with no tip, just a snipped off edge) to add a swirl of chocolate buttercream ontop, and used that offset spatula to flatten the frosting down.
  6. Garnish with additional M&Ms as desired.
