Who wouldn’t prefer mini chocolate chips to watermelon seeds? A fun and unexpected addition to these lightly flavored watermelon cupcakes, the chocolate chips add some whimsy but are completely optional.

The green buttercream frosting seen here is vanilla-flavored but I’ve also experimented with watermelon cake and lime frosting and it was delicious!

I just used a simple frosting swirl technique with no special tips required. You can add two frosting colors or shades to your piping bag for a color swirl or special effect, but these cupcakes are all about “wow” without a ton of effort.

(We’re even doctoring a box of white cake mix here, this is about easy & fun party food!)

Watermelon Cupcakes

  • Author: Jennifer Tammy


  • White or yellow pre-made cake mix
  • PLUS ingredients the cake mix calls for
  • 1/2 cup mini chocolate chips
  • Watermelon Kool-aid packet
  • Red and green food coloring
  • 1 cup butter
  • 3-4 cups powdered or icing sugar
  • 1 teaspoon salt
  • 1 Tablespoon vanilla OR Lime Kool-aid packet
  • 4 Tablespoons heavy cream or milk


  1. Preheat oven to 350F and line a cupcake pan with liners.
  2. Make cake mix according to package directions.
  3. Stir in the Watermelon Kool-aid packet and chocolate chips before adding additional red food coloring until you reach a pleasant pink color (you don’t want a deep red).
  4. Fill the cupcake liners about 2/3 of the way full and bake for 18-22 minutes until an inserted toothpick comes out clean.
  5. Mix the butter, 3 cups of the powdered sugar, salt, vanilla or Lime Kool-aid packet, and heavy cream or milk together.
  6. Adjust the consistency by adding more icing sugar with heavy cream and then add the green food coloring one drop at a time until you reach your desired color. Spoon the frosting into a piping bag, snip off the tip, and swirl onto your cupcakes – starting at the middle and swirling out, then swirling back in towards the center.
  7. Sprinkle with a few additional mini chocolate chips.
