- ½ cup 114g sour cream
- ¼ cup 59ml milk, I used skim

- 3-4 cups 339-454g powdered sugar
- ½ tsp powdered watermelon kool aid mix
- small amount of red gel food coloring to give the buttercream a pinkish color
- mini chocolate chips
Preheat your oven to 350°F (175°C) and line a cupcake tin with liners.
Beat butter and sugar until light and fluffy. Add egg whites, then mix in sour cream, milk, and vanilla.
In a separate bowl, whisk flour, baking powder, and salt. Gradually add to the wet mix.
Add a drop of green food coloring for a watermelon rind look, then mix until color is even.
Fill liners halfway and bake for 18–20 minutes. Let them cool completely.
For frosting, beat butter until creamy. Gradually add powdered sugar, watermelon Kool-Aid mix, and red gel coloring.
Frost the cooled cupcakes using a piping bag or spatula.
Finish by sprinkling mini chocolate chips on top to mimic watermelon seeds.
