Description
These Watermelon Cupcakes are a delightful summer treat featuring moist, light green cupcakes flavored subtly with a hint of vanilla and sour cream, topped with a vibrant pink watermelon-flavored buttercream. The buttercream is colored with red gel and powdered watermelon Kool-Aid mix for a refreshing, fruity twist, and finished with mini chocolate chips that mimic watermelon seeds for a fun and festive look.
Ingredients
Cupcakes
- 1/2 cup (113g) unsalted butter, room temperature (1 stick)
- 3/4 cup (149g) granulated sugar
- 2 large egg whites
- 1/2 cup (114g) sour cream
- 1/4 cup (59ml) milk (skim recommended)
- 1 tsp vanilla extract
- 1 1/4 cup (150g) all-purpose flour
- 1 tsp baking powder
- 1/4 tsp salt
- Leaf green food coloring (Wilton or similar)
Watermelon Frosting
- 1 1/2 cups (339g) unsalted butter, room temperature (3 sticks)
- 3-4 cups (339-454g) powdered sugar
- 1/2 tsp powdered watermelon Kool-Aid mix
- Small amount of red gel food coloring
- Mini chocolate chips (for garnish)
Instructions
- Preheat Oven: Preheat your oven to 350º F (175º C) and line a muffin pan with cupcake liners.
- Prepare Batter: In a mixing bowl, beat the butter and granulated sugar with an electric mixer for 1-2 minutes until fluffy. Add the egg whites, sour cream, milk, and vanilla extract and beat lightly to combine.
- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.
- Mix Wet and Dry Ingredients: Gradually add the flour mixture to the wet ingredients, incorporating a few spoonfuls at a time, until just combined. Add leaf green food coloring a little at a time until the desired light green color is achieved.
- Fill Cupcake Liners: Spoon the batter into the cupcake liners, filling each about 1/2 to 3/4 full for even baking.
- Bake Cupcakes: Bake at 350º F for 17-19 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Allow cupcakes to cool completely on a wire rack before frosting.
- Make Frosting: In a mixing bowl, beat 1 1/2 cups unsalted butter until smooth, about 2 minutes. Add 2 cups powdered sugar and the powdered watermelon Kool-Aid mix, beating to combine.
- Adjust Frosting Consistency: Gradually add up to 2 more cups powdered sugar as needed, mixing well to achieve a spreadable and pipeable consistency.
- Add Color: Stir in a small amount of red gel food coloring to give the frosting a pinkish watermelon hue. Beat until smooth and combined.
- Pipe Frosting: Transfer the buttercream to a large piping bag fitted with a Wilton 1M tip. Starting in the center of each cupcake, pipe the frosting by swirling outward, then swirl back toward the center to build layers of frosting artfully stacked.
- Garnish: Sprinkle mini chocolate chips on top of the frosting to resemble watermelon seeds and add a fun finishing touch.
Notes
- Make sure the cupcakes are completely cool before frosting to prevent the buttercream from melting.
- Use room temperature butter for both the batter and frosting to ensure smooth mixing.
- Adjust the green food coloring to get just the right pastel shade reminiscent of watermelon rind.
- Powdered watermelon Kool-Aid is key to achieving that authentic watermelon flavor in the frosting.
- Mini chocolate chips act as ‘seeds’ for a creative and thematic decoration.
- If you prefer, use full-fat milk for a richer cupcake texture.
- Store cupcakes in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days.
