Method
Preparation
- Preheat your oven to 325°F and line a 12-cup muffin tin with cupcake liners.
- In a medium bowl, whisk together the cake flour, baking powder, baking soda, and salt.
- In a 2-cup measuring cup, combine the whole milk, sour cream, and 1 teaspoon of vanilla, then whisk gently.
- Using a stand mixer fitted with a paddle attachment, cream the first stick of butter with granulated sugar and vanilla on medium speed until light and fluffy.
- Add the egg whites and mix until fully incorporated.
- Alternate adding the dry and wet ingredients, mixing until the batter is smooth.
- Scoop the batter into the cupcake liners using a ¼ measuring cup or ice cream scooper.
Baking
- Bake for 20-22 minutes until the tops spring back when touched.
Making the Buttercream
- In another mixing bowl, cream the second stick of butter with powdered sugar and 1 teaspoon of vanilla extract.
- Gradually add whole milk until the buttercream reaches a spreadable consistency.
- Add gel food coloring as desired.
Serving
- Serve cupcakes on a cake stand with a dollop of buttercream on top.
Notes
Always use room-temperature ingredients for a smooth batter. Don't skip the scraping step to ensure even mixing. For softer cupcakes, reduce baking time slightly.
