If you are looking for a perfect white cupcake recipe that is pretty easy to make, you are in the right place. This doctored up cake mix recipe makes fluffy cupcakes that are tender and delicious. They make great wedding cupcakes or are perfect for a party.
Preheat oven to 325°F and place cupcake liners in 36 cupcake wells.
In a large mixing bowl, whisk together 1 white cake mix, 1 cup all-purpose flour, 1 cup granulated sugar, ½ teaspoon salt, and ¼ teaspoon baking powder until well mixed and lump free.
Add the 1⅓ cups water, 2 Tablespoons vegetable oil, 2 teaspoons vanilla extract, 1 cup sour cream, and ½ cup egg whites ingredients into the bowl with the dry ingredients and beat on low until the ingredients combine. Then beat with an electric mixer on medium speed for two minutes. (A hand mixer works great for this, but so does a stand mixer with the paddle attachment.)
Scoop the batter into lined cupcake tins, a large cookie scoop or ice cream scoop helps to keep them evenly sized and reduces the mess. Each well should get about 3 Tablespoons of batter and be about ⅔ full.
Bake for 18-22 minutes or until the tops spring back when lightly touched with a finger. (They shouldn't take on much color.)
Cool in the cupcake tin for about 5 minutes then remove to a wire rack to cool completely.
Notes
It is fun to use 1 teaspoon of vanilla extract and a teaspoon of another flavoring. We like using almond extract, lemon extract, or creme bouquet but you can use whatever you would like.
