Alton Brown's Sugar Cookies

  • 1 cup sugar
  • 1 cup unsalted butter, softened
  • 1 egg, beaten
  • 1 tbsp milk
  • 3 cups flour
  • 3/4 tsp baking powder

Sift together flour, baking powder, and salt. Set aside. Place butter and sugar in large bowl of electric stand mixer and beat until light in color. Add egg and milk and beat to combine. Put mixer on low speed, gradually add flour, and beat until mixture pulls away from the side of the bowl. Divide the dough in half, wrap in waxed paper, and refrigerate for 2 hours.

If using dough for chocolate peppermint pinwheels, do not chill yet.
