  • 1 box white cake mix (18.25 ounces)
  • 1 box lime Jello (not sugar-free) (3 ounces)
  • 3 egg whites
  • 1/3 cup vegetable oil
  • 1 1/4 cups water
  • 8 ounces white chocolate, melted
  • 1/2 cup butter, softened
  • 4 cups powdered sugar
  • 1/2 teaspoon Kool-Aid powdered mix (watermelon flavor)
  • 3-4 tablespoons milk
  • 3/4 cup mini chocolate chips


  1. Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
  2. In a mixing bowl, combine the white cake mix, lime Jello powder, egg whites, vegetable oil, and water. Beat for 2 minutes until well blended.
  3. Fill each cupcake liner about 2/3 full with the cake batter. Bake in the preheated oven for 15-18 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. Be careful not to overbake. Allow the cupcakes to cool completely.
  4. Once the cupcakes are cooled, spread melted white chocolate over the top of each cupcake. Let the chocolate set while you prepare the frosting.
  5. In a stand mixer or using a hand mixer, beat the softened butter with powdered sugar, Kool-Aid powdered mix, and milk until fluffy and smooth, about 3-5 minutes.
  6. Transfer the frosting to a piping bag fitted with your desired tip (such as 6S). Pipe the frosting onto each cupcake.
  7. Immediately sprinkle mini chocolate chips over the frosted cupcakes to resemble watermelon seeds.
  8. Serve and enjoy these adorable and delicious watermelon cupcakes!

Serving and Storage Tips:

Serving Tips:

  1. Enhance the presentation of your Watermelon Cupcakes by garnishing each with a small wedge of fresh watermelon or a slice of lime on the side.
  2. Serve these cupcakes on a decorative platter or cake stand adorned with green foliage or paper cutouts shaped like watermelon leaves for a festive touch.
  3. Arrange the cupcakes in a circular pattern to mimic the appearance of a watermelon slice for an eye-catching display.
  4. For a refreshing twist, serve these cupcakes with a scoop of watermelon sorbet or a glass of freshly squeezed limeade to complement the flavors.

Storage Tips:

  1. Store any leftover Watermelon Cupcakes in an airtight container at room temperature for up to 2 days to maintain freshness.
  2. To extend the shelf life, refrigerate the cupcakes in an airtight container for up to 4-5 days, ensuring they are well-sealed to prevent them from drying out.
  3. If frosted, store the cupcakes in the refrigerator to keep the frosting firm and prevent it from melting.
  4. For longer storage, you can freeze unfrosted cupcakes in an airtight container for up to 1-2 months. Thaw them overnight in the refrigerator before serving.
  5. To maintain the integrity of the chocolate chip “seeds,” store the cupcakes in a single layer to prevent them from getting smudged or misshapen.
  6. Before serving leftover cupcakes, allow them to come to room temperature for 10-15 minutes to soften slightly and enhance their flavor and texture.
  7. For an easy grab-and-go snack, pack individual cupcakes in airtight containers or zip-top bags for picnics, lunchboxes, or road trips.

By following these serving and storage tips, you can ensure that your Watermelon Cupcakes remain fresh, delicious, and visually appealing, ready to be enjoyed whenever you crave a taste of summer sweetness.
