1. Preheat oven to 35
2. To prepare cupcakes, lightly coat 24 muffin cups with cooking spray. Weigh or lightly spoon flour into dry measuring cups; level with a knife. Weigh or lightly spoon potato starch into a dry measuring cup; level with a knife.
3. Combine flour, potato starch, baking powder, and 1 teaspoon salt, stirring well with a whisk.
4. Place 1 3/4 cups sugar and 10 tablespoons butter in a large bowl; beat with a mixer at medium speed until light and fluffy.
5. Add eggs, 1 at a time, beating well after each addition.
6. Combine milk and half-and-half.
7. Add flour mixture and milk mixture alternately to butter mixture, beginning and ending with flour mixture. Beat just until combined. Fold in bourbon and 1 tablespoon vanilla. Divide batter evenly among prepared muffins cups; bake at 350 for 18 minutes or until a wooden pick inserted in center comes out clean. Cool in pans 5 minutes.
8. Remove cupcakes from pans; cool completely on wire racks.

Reduce mixer speed to low; continue beating until egg white mixture cools (about 12 minutes).
