Peanut Butter Chocolate Gems

1 cup butter or margarine
1 cup peanut butter
1 (16 ounce) pkg powdered sugar...I always used 3/4 lb
1 1/2 cups graham cracker crumbs
1 (12 ounce) package semisweet chocolate morsels, melted (can use microwave)

Melt butter in a medium saucepan. (Can use Microwave) Remove from heat, and stir in next 3 ingredients; mix well. Press mixture into an ugreased 13x9x2 baking pan and spread melted chocolate morsels evenly over the top. Chill 30 minutes, or until chocolate is set enough to cut. Careful, if these get too hard before cutting, they are difficult to cut. Can be cut, then put back in the fridge to harden until firm. Cut into 1 1/2 inch squares. Makes about 4 dozen. These freeze beautifully.
