4 cups graham cracker crumbs
2 cups miniature marshmallows
1 cup chopped nuts
1 cup powdered sugar
1 12-oz bag semi-sweet chocolate chips
3/4 cup evaporated milk
Mix together the graham cracker crumbs, marshmallows, nuts and powered sugar in a large bowl. Melt the chocolate chips in the microwave, stirring every 30 seconds until smooth. Add the evaporated milk to the chocolate and stir until smooth and incorporated. Pour chocolate over graham cracker marshmallow mixture and toss until well combined.
Press mixture into a well-greased nine inch pan and pat down (easiest to do with wet hands!). Place in fridge until firm (about an hour). Dust with powdered sugar and slice into squares.
