These Easy White Cupcakes are such a great way to use up leftover egg whites! They’re light, fluffy and and topped with a simple sour cream frosting. Adding a little bit of sour cream to the frosting helps cut the sweetness and adds a bit of tang which perfectly complements these cupcakes. They’re great for any type of celebration!

Ingredient Breakdown

Cake flour – this gives the cupcakes structure and a more tender crumb than all-purpose flour.

Baking powder and baking soda – both are necessary to help the cupcakes rise.

Butter – provides flavor and structure. I always recommend using unsalted butter but salted butter works if that’s all you have on hand, just be sure to omit the 3/4 teaspoon of salt. Do not use cold or melted butter.

Granulated sugar – provides sweetness and texture.

Vegetable oil – adds moisture and tenderizes cupcakes.

Egg whites – binds the ingredients, provides structure and gives the cupcakes a light and fluffy texture.

Vanilla extract and salt – enhances flavor. Always use pure vanilla extract instead of imitation for best flavor.

Buttermilk – adds flavor and moisture.

How To Make White Cupcakes

1. Make the White Cupcakes: In a small bowl combine the cake flour, baking powder, salt and baking soda.

2. Using a hand mixer or a stand mixer fitted with the paddle attachment cream the butter and granulated sugar until light and fluffy then add the vegetable oil. Mix in the egg whites and vanilla extract.

3. Fold in half of the dry ingredients then add all of the buttermilk. Fold in the remaining half of the dry ingredients until just combined.

Cupcake batter

4. Scoop batter into prepared pans 3/4 full. Bake at 350°F for 18 minutes or until a toothpick comes out clean. Let cupcakes cool completely.

6. Add confectioners’ sugar and mix on low until combined. Add salt, to taste. Decorate cooled cupcakes as desired. Store White Cupcakes in an airtight container for up to 5 days in the fridge.

Pro Tips For White Cupcakes

  • Weigh your ingredients using a kitchen scale! Measuring ingredients by volume is not accurate.
  • Be sure to use cake flour because it makes the cupcakes more tender than all-purpose flour.
  • Don’t over mix the cupcake batter otherwise it will develop too much gluten and be dense/gummy.
  • Do not over fill your cupcake liners. Only fill them 3/4 full. I love this cookie scoop because it fills them with the perfect amount of batter!
  • Wait until the cupcakes are COMPLETELY COOLED before frosting otherwise the frosting will melt and slide off.
