Ingredients

1 & 1/2 cups all-purpose flour
1 cup granulated sugar
1 teaspoon baking powder
1/2 teaspoon baking soda
4 large egg whites
1 & 1/2 teaspoons vanilla extract
1 cup milk
1/4 cup vegetable oil
1/3 cup rainbow sprinkles

For the frosting

1 cup unsalted butter softened
4 cups powdered sugar
2 tablespoons milk
1 & 1/2 teaspoons vanilla extract
1/4 teaspoon fine salt
¼ cup rainbow sprinkles

Instructions

Preheat the oven to 350°F. Line cupcake pan with liners and set aside.
Add the dry ingredients: flour, sugar, baking powder, and baking soda to the body of a stand mixer with the paddle attachment and stir to combine on low speed.
Add the egg whites and vanilla, stir until smooth, and scrape down the sides as needed with a rubber spatula.
Stir in the milk and oil until combined, scraping down the sides. Stir in the colorful sprinkles.
Fill the cupcake liners ⅔ of the way full with cupcake batter, about 3 tablespoons each, do not overfill.
Bake for 16-18 minutes until a toothpick inserted into the center comes out clean.
Let cool in the pan for 10 minutes. Take the cupcakes out and cool them completely on a wire rack.
Once the cupcakes are cool, make the frosting by placing the butter in the body of a stand mixer with the paddle attachment and cream butter until smooth.
Add the powdered sugar a little at a time until fully mixed in.
Add the milk, vanilla, and salt, and stir to combine. Scrape down the sides.
Place the mixer on medium-high speed and whip for 3 minutes until light and fluffy on medium speed. Stir in the bright rainbow sprinkles.
Frost the confetti cupcakes with the frosting. I like to use a piping bag with a Wilton 2A round tip attached. Add more sprinkles on top if desired, and serve.

Notes

This makes 18 cupcakes, but you can easily double it to feed more or halve the recipe as needed.
