When I came across this recipe I thought it not only sounded delicious, but it looked easy to make.  Right on both counts--delicious and easy!

Rocky Road Squares

1/2 cup butter
1/2 cup brown sugar
1 cup all purpose flour
1/2 cup graham cracker crumbs
2 cups miniature marshmallows
1 (6 oz.) package semi-sweet chocolate chips
1/2 cup nuts, chopped

Combine butter and sugar and beat until light and fluffy.  Mix flour and graham cracker crumbs together and add to creamed mixture.  Pat into greased 9 x 9 or 11 x 7 x 1.5 inch pan.  Sprinkle marshmallows, chocolate chips, and nuts on top of crust.  Bake at 375 degrees for 15 - 20 minutes.  Cool and cut into squares.
