I know that for convenience you could just buy an already made graham cracker crust in a metal pan. Try to resist doing it. A homemade graham cracker crust tastes so much better than a store-bought one. The very best tasting graham cracker crusts are made by crushing the graham crackers yourself. Don't skimp on the butter or sugar either. Use real butter and sugar in the amounts required by the recipe. Baking the crust will pull these ingredients together. I promise you'll get compliments on the crust as it actually has some flavor and good texture.
