1 egg
1/2 tsp. vanilla

Cream butter, peanut butter and both sugars together. Beat in egg and vanilla. Sift together flour, baking soda and salt. Stir into creamed mixture. Preheat oven to 375 degrees. Shape dough into 1 inch balls and put into ungreased 1 1/2 muffin tins. Bake 8 to 10 minutes or until lightly browned.

Immediately after removing from oven press a peanut butter cup into the center of each cookie. Let cool at least 15 minutes then carefully remove from tins. Store in airtight containers.
