Ingredients

Cake Batter

  • ½ cup unsalted butter (softened to room temperature)
  • ¾ cup granulated sugar
  • 2 large eggs (at room temperature)
  • 1 ½ teaspoons pure vanilla extract
  • ½ cup yogurt (natural or Greek)
  • 1 ¼ cups all-purpose flour
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • Green food coloring

Watermelon Buttercream Frosting

  • 1 cup unsalted butter (softened)
  • 4-5 cups powdered sugar
  • ¼ cup heavy cream (or whole milk, or half and half)
  • 2 teaspoons pure vanilla extract
  • 3 ounces watermelon Kool-Aid drink mix (from a packet, unsweetened)
  • ¼ teaspoon salt
  • Red food coloring
  • ¼ cup mini chocolate chips
  • Green cupcake liners


Instructions

  1. Preheat Oven and Prepare Pan: Preheat the oven to 350°F (180°C) and line a muffin pan with 12 green cupcake liners. Set aside while preparing the batter.
  2. Cream Butter and Sugar: In a large bowl, use an electric hand mixer at medium speed to cream the softened butter and granulated sugar until the mixture is lighter in color and smooth. Then, add the eggs one at a time, mixing well after each egg. Incorporate the vanilla extract and yogurt until fully combined. Set aside the wet ingredients.
  3. Mix Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking powder, and salt until evenly combined.
  4. Combine Wet and Dry Ingredients: Add about one-third of the dry ingredients to the wet ingredients and mix with the electric mixer until combined. Then add the remaining dry ingredients and mix just until fully incorporated, careful not to overmix.
  5. Tint the Batter: Add green food coloring drop by drop to the cake batter until the desired lime green hue is achieved.
  6. Fill Cupcake Liners and Bake: Fill the cupcake liners halfway to two-thirds full with the batter. Bake in the preheated oven for about 20 minutes or until a toothpick inserted into the center comes out clean. Remove from oven and allow cupcakes to cool completely before frosting.
  7. Make Watermelon Buttercream Frosting: In a large bowl, cream the softened butter until smooth using an electric mixer. Gradually add powdered sugar and the watermelon Kool-Aid powder, beating until smooth and fluffy. Add salt, vanilla extract, and heavy cream, mixing well until the frosting reaches a pipeable consistency. Adjust with more cream as needed. Add red food coloring to achieve desired watermelon pink color.
  8. Decorate Cupcakes: Transfer the frosting to a piping bag fitted with a large star tip. Swirl the frosting over each cooled cupcake to create a decorative top. Finish by sprinkling mini chocolate chips on top to resemble watermelon seeds.

Notes

  • If you prefer, you can substitute the yogurt with sour cream for a slightly tangier cake.
  • The watermelon Kool-Aid powder provides the signature flavor and a natural pink hue in the frosting; ensure it’s unsweetened to avoid overly sweet frosting.
  • For a dairy-free version, substitute butter with dairy-free margarine and heavy cream with coconut cream, though texture and flavor may vary.
  • Allow cupcakes to cool completely before frosting to prevent the buttercream from melting.
  • The green and red food coloring amounts can be adjusted based on your desired intensity of cupcake and frosting colors.
