Instructions
Vanilla Cupcakes
Preheat the oven to 350F/177C convection (325F/163C conventional) and line a mini muffin tin with cupcake liners (preferably a light colored pan).
In a medium bowl, whisk together the cake flour, baking powder, salt and sugar.
3/4 cup (86g) cake flour, 1 tsp baking powder, 1/4 tsp salt, 1/2 cup (100g) granulated sugar
Add the melted butter to the dry ingredients and whisk together until it's combined.
1/4 cup (56g) butter
Add the egg white and vanilla extract and mix until they're fully combined.
1 large, 1 tsp vanilla extract
Add the milk and sour cream and mix just until the cupcake batter is smooth.
1/4 cup (59mL) whole milk, 1/4 cup (56g) sour cream
Fill each cupcake liner about 3/4 full. Bake for 10-12 minutes. When you press on the center of the cupcake it should spring back.*
Remove from the oven and let them cool in the pan for 10 minutes, then move them to a cooling rack. Allow the cupcakes to cool completely before frosting.
Vanilla Buttercream
Place the butter in the bowl of a stand mixer, fitted with a whisk attachment. Beat the butter for about five minutes, scraping the bottom and sides of the bowl halfway through.
1/2 cup (113g) unsalted butter
Add the powdered sugar and vanilla extract and beat the frosting on low until it's combined. Then increase the speed to medium-high for another 5 minutes, scraping the bottom and sides of the bowl halfway through.
2 cup (240g) powdered sugar, 1-2 tsp vanilla extract
Add the heavy whipping cream and beat the frosting until it's well combined. Pipe onto the cooled cupcakes and decorate however you like.
2-4 Tbsp (30-60mL) heavy whipping cream
Notes
*the vanilla cupcake recipe was designed to stay pale so don't look for a golden brown color when it's finished baking.
