I grew up with this recipe, I remember my mom teaching me how to make Graham Cracker Dream Bars. When I made these for my husband shortly after we were married, he thought they were the greatest thing ever…and that I was a keeper!
1 box whole graham crackers
1 c. butter
1 c. sugar
1/4 c. milk
1 egg, beaten
1c. crushed graham crackers
1c. chopped walnuts
1 c. coconut

1/2 c. butter,melted
