Cocoa Snaps

In a bowl whisk together flour, sugar, cocoa powder, baking powder and salt and with fingers blend in butter until incorporated. Stir in egg until mixture is combined well. Cover dough in bowl and chill until firm, about 1 hour.

Spoon level tablespoons of dough onto a sheet of wax paper and cut each in half. With floured hands roll each piece of dough into a ball and arrange, evenly spaced, on baking sheet. Flatten each ball with a floured metal spatula into a disk about 2 inches in diameter and bake in middle of oven 7 to 8 minutes, or until cookies are set but not hard. Cool cookies on racks. (Cookies will continue to crisp as they cool.)
