Preparation Steps
- Preheat your oven to 325°F (165°C) and line a 12-cup muffin tin with colorful cupcake liners.
- In a medium bowl, whisk together the cake flour, baking powder, baking soda, and salt.
- In a separate bowl, combine the whole milk, sour cream, and vanilla extract, mixing until smooth.
- In a large mixing bowl, beat the softened unsalted butter and granulated sugar together until light and fluffy, about 3–4 minutes.
- Add the egg whites one at a time to the butter-sugar mixture, mixing well after each addition.
- Gradually add half of the wet mixture to the butter-sugar-egg whites, followed by half of the dry ingredients, and repeat until combined.
- Fill each cupcake liner about three-quarters full with the batter and bake for 20–22 minutes.
- Allow the cupcakes to cool in the tin for about 5 minutes before transferring them to a wire rack to cool completely.
- For the buttercream, beat the softened unsalted butter until creamy, then gradually add sifted powdered sugar, mixing until smooth.
- Frost the cooled cupcakes using a piping bag fitted with your favorite decorating tip.
