Peanut Butter Babies

1/2 cup margarine (I used butter)
1/2 cup peanut butter
1/2 cup sugar
1/2 cup brown sugar
1 1/4 cup flour
1 egg
1/2 tsp. vanilla
3/4 tsp. baking soda
1/2 tsp. salt
Approx. 24 miniature peanut butter cups

Cream margarine and peanut butter. Add sugars and flour and beat until fluffy. Add eggs, vanilla, salt and soda. Chill one hour, shape into 1 inch balls. Spray mini-muffin pans with Pam. Put balls into pans and bake at 350 for 12 minutes. Remove and immediately press a mini peanut butter cup into the middle of the cookies. Cool completely in pans. She recommends the Walmart brand of PB cups.
