Make the Crumbs: Grind graham crackers into fine crumbs using a food processor or blender. Alternatively, place them in a zip-top bag and crush with a rolling pin.

Mix Ingredients: In a medium bowl, stir together the graham cracker crumbs and sugar. Add the melted butter and mix until the texture is thick, sandy, and slightly coarse.

Form the Crust: Press the mixture evenly into the bottom and up the sides of an ungreased 8-, 9-, or 10-inch pan. Use medium pressure, firm but not too hard. A small measuring cup can help smooth the surface.

Pre-Bake or Chill: For baked desserts, pre-bake the crust at 350°F (177°C) for 10 minutes, or follow your filling recipe’s instructions. For no-bake desserts, cool the crust completely before adding the filling.
