These are yummy, no-bake and taste like a peanut butter cup, more a candy than a cookie. You can use a cookie sheet, or for thicker cookies, a 9x13 pan.
2 C peanut butter
3/4 cup butter or margarine (soften to room temperature)
3 3/4 C powdered sugar
3/4 C brown sugar
3/4 t vanilla
6 oz chocolate chips
2 T butter
Combine first 5 ingredients until smooth. Press into cookie sheet.
In a saucepan, melt the chips and butter. Spread over mixture in cookie sheet. Chill at least 2 hours before cutting into small squares.
