In a food processor, grind the graham crackers until they are a fine powder. This took about 1 and a half of the inner packages.
In a medium sized bowl, combine the graham cracker crumbs, ground coffee and sugar. Stir until combined.
Add melted butter, and stir until evenly coated.
Press mixture in to a prepared baking dish. I used mini tart pans, but you can use any standard pie dish. Bake for 7-8 minutes and let cool completely.
