Reeses Squares (no bake)

I made this recipe because I was really craving it and it sounded easy (it is). I made, like a third of the recipe and they turned out well (how could a no-bake recipe not?).

1 1/2 c. graham cracker crumbs
1 lb (3 - 3 1/2 c.) powdered sugar
1 1/2 c. peanut butter
1 c. butter, melted
1 (12 oz.) bag milk chocolate chips


1. Combine graham cracker crumbs, sugar & peanut butter until mixed well.
2. Blend in melted butter until well combined.
3. Press mixture evenly in a 9 x 13" pan.
4. Melt chocolate chips in microwave or in double boiler.
5. Spread over peanut butter mixture.
6. Chill until just set and cut into bars (they are hard to cut if the chocolate gets 'rock hard')
