1 cup butter
1 cup creamy peanut butter
1 egg, lightly beaten
3 cups vanilla sweetened chocolate syrup
1 (12 ounce) can marshmallow creme
Preheat the oven to 350 degrees F (175 degrees C). Spread peanut butter cookies evenly on a cookie sheet. Line cookie sheets with frosting.
Combine the butter and peanut butter; frost both sides. Place peanut butter cookies on cookie sheets, but cut into 1 inch square as desired.
Bake for 8 to 10 minutes in the preheated oven. Allow cookies to cool on baking sheet for 5 minutes before removing to a wire rack to cool completely.
