S'mores Bars with Peanut Butter Cups
Adapted from Cuisine at Home, Holiday Cookies

1 stick (1/2 c) unsalted butter, softened
1/3 c sugar
1 egg
1/2 tsp vanilla extract
2 c graham cracker crumbs
1/3 c flour
Pinch of salt

15 mini-peanut butter cup candies (Wendy note: I think Rolo's might work too)
2 c mini marshmallows
1/2 c semi-sweet chocolate chips

Preheat oven to 350 degrees. Coat a 13x9 inch baking bap with nonstick spray.

Cream butter, sugar, egg, and vanilla in a bowl with an electric mixer. The mixture will look curdled. Stir in graham cracker crumbs, flour, and salt. Reserve 1/4 c of the mixture.

Press remaining mixture into the pan. The layer will be very thin. Bake for 12 minutes or until golden around the edges. Remove from oven, and set oven to Broil.

Top the hot base with peanut butter cups, marshmallows, and chocolate chips. Press lightly to adhere. Sprinkle the reserved graham cracker mixture in clumps over the top. Broil just until the marshmallows toast - only a minute or two.

Cool bars for at least 30 minutes before cutting. Coat knife with some nonstick spray to keep it from sticking when cutting.
