Notes
If your kitchen is warm, chill the dough for about 10 minutes before rolling it into balls.This makes about 24 small cookies. For bigger ones, make the balls twice the size and bake them for about 4 minutes longer.For more heat, use 2 teaspoons of chipotle powder, or add about 1/4 teaspoon of cayenne.Let the cookies cool completely on a wire rack before you store them in an airtight container.
