The Fluffiest Cupcakes In The World - cooking recipe

Ingredients

1/2 cup unsalted butter, at room temperature
1 cup granulated sugar
2 large eggs, separated, at room temperature
2 tablespoons vanilla extract
1 1/2 cups all-purpose flour
1 1/2 teaspoons baking powder
1/4 teaspoon salt
1/2 cup milk
1/8 teaspoon cream of tartar

Preparation

Preheat the oven to 350\u00b0F Line cupcake pans with liners.
With an electric mixer on medium speed beat the butter until soft, about 2 minutes. Add the sugar and beat until light and fluffy, about 3 minutes. Add the egg yolks, one at a time, beating after each addition. Add the vanilla and beat until combined.
In a separate bowl combine the flour, baking powder, and salt.
With the mixer on low speed, alternately add the flour mixture and milk until combined.
In a small bowl with a clean mixer on high speed beat the egg whites until foamy. Add the cream of tartar and continue beating until stiff peaks form. With a rubber spatula stir a little of the whites into the batter to lighten it, then fold in the remaining whites until combined. Do not overmix.
Fill the cupcake liners three-quarters full. Bake for about 15-20 minutes or until a toothpick inserted in the center of a cupcake comes out clean. Cool cupcakes in the pan.
