1 1/4 cups all-purpose flour
1 1/2 tsp. baking power
1/4 tsp. salt
3/4 cup sugar
6 Tbs. (3/4 stick) unsalted butter, at room temperature
1 whole egg plus 1 egg white, at room temperature
1 tsp. vanilla extract
1/2 cup milk
In a large bowl, whisk the butter, sugar, vanilla and eggs together. In another bowl add all the other ingredients and put all the ingredients in the large bowl and beat. Beat until all is combined. Add less sugar if you don't like it a bit sweet.
Preheat an oven to 350F. Line a standard muffin pan with paper or foil liners. The cupcakes should take 18 to 20 minutes to bake. Let it cool completely, about 1 hour.
