Please note: Skye Shaughnessy noted that we left out an important ingredient when we originally posted this recipe - the brown sugar. We have included it here and would like to thank her for letting us know!
Preheat oven to 350°. Combine peanut butter, butter and brown sugar. Mix thoroughly. Add egg and stir in flour, baking powder and cinnamon. If the dough seems too sticky, add more flour (in 1/8 cup increments). The dough should be soft enough to wrap around the kisses, but not so sticky that you can't get it off your hands. Cover dough in plastic wrap and chill at least one hour. Wrap about one teaspoon of dough around each chocolate kiss. Place cookies on ungreased baking sheets and bake 10-12 minutes. Remove from baking sheets and cool. Makes 3 1/2 dozen cookies.
