1/2 c. peanut butter
1/2 c. sugar
1/2 c. brown sugar, firmly packed
1 egg
1 1/2 c. all-purpose flour
3/4 tsp. baking soda
1/2 tsp. baking powder

Mix together butter, peanut butter, sugars, and egg. Blend in remaining ingredients except jelly. Cover and chill. Shape dough in small balls. Place 12 balls on baking sheet lined with waxed paper.
