3/4 box of graham cracker crumbs
1 stick of butter
1/4 c. sugar
2 cans of Eagle Brand Condensed milk
1 - 12 oz. can frozen lemonade concentrate
1 - 12 or 16 oz. carton of Cool Whip, thawed
yellow food coloring (optional)

Mix sugar and crumbs in 13 x 9 inch glass pyrex dish. Add butter. Microwave just until butter is melted. Mix and pat in dish with large spoon. Mix condensed milk and frozen lemonade concentrate gently with a spoon until thick. If you want the filling to be a deeper yellow then you may add a drop or two of yellow food coloring. Pour over the graham cracker crust. Spread Cool Whip over filling. Freeze until time to serve. It will not freeze hard; it will just be really cold.
