Cupcake Preparation
- Preheat your oven to 325°F (163°C) and line a muffin tin with cupcake liners.
- In a medium bowl, whisk together cake flour, baking powder, baking soda, and salt.
- In another bowl, combine whole milk, sour cream, and vanilla extract. Whisk until smooth.
- In a large bowl, beat unsalted butter and granulated sugar until light and fluffy.
- Gradually add egg whites and mix until fully incorporated.
- Combine wet and dry ingredients by alternating between them until just combined.
- Fill each cupcake liner about ¾ full with batter.
- Bake for 20-22 minutes, until springy to touch or a toothpick comes out clean.
- Allow cupcakes to cool in the tin for 5 minutes then transfer to a wire rack.
- Prepare frosting by beating unsalted butter and powdered sugar until crumbly, then add milk and vanilla extract.
- If desired, color the frosting and pipe it onto completely cooled cupcakes.
