- 1/2 cup butter, softened
- 1/2 cup white sugar
- 1 egg
- 1 teaspoon vanilla extract
- 3/4 cup whole wheat flour
- 1/2 teaspoon baking powder
- 1/3 cup almond milk
- 3/4 cup vanilla frosting, divided
- 4 drops blue food coloring, or as needed
- Preheat oven to 350 degrees F (175 degrees C). Line 6 muffin cups with paper liners.
- Beat butter and sugar together in a bowl using an electric mixer until creamy; beat in egg and vanilla extract. Stir flour and baking powder into creamed butter mixture until combined; stir and almond milk until batter is smooth. Spoon batter into the prepared muffin cups.
- Bake in the preheated oven until cupcakes are lightly browned, 20 to 25 minutes. Cool cupcakes completely, about 30 minutes.
- Mix 1/2 cup frosting and food coloring together in a bowl until color is even. Spoon the remaining 1/4 cup frosting into a small plastic bag and cut a small hole in the bottom corner.
- Frost the cooled cupcakes with blue frosting and then draw a star on top using the white frosting piping bag.
