Preheat the oven to 350°F (180°C).
Have ready a 9-inch pie pan with a removable bottom. An 8-inch also works, but the crust will be thicker. You can also use a pie plate without a removable bottom, which is very popular during the holidays.
For the cookie crumbs, the easiest way is to use a food processor and process until you have fine crumbs. Make sure there are no large pieces or that it's a very coarse crumb mixture. That will prevent the mixture from compressing well. You can also make the crumbs by hand, but it takes a while and some patience. Crush the cookies with a rolling pin. It's easier if you put them in a large plastic bag, like a Ziploc bag, leaving it a little bit open to let the air out as you roll.
By hand: mix 1 ¾ cups fine graham cracker crumbs with 3 tablespoons brown sugar in a medium bowl. Add ½ cup butter, melted, and combine everything until it resembles wet sand and no dry spots remain.
Food processor: You can make the mixture directly in the bowl of the processor. Process 1 ¾ cups fine graham cracker crumbs with 3 tablespoons brown sugar and add ½ cup butter, melted, to the bowl of the processor. Pulse a few times, and you have your graham mixture ready.
Press mixture onto a 9-inch (24cm) springform pan, starting at the edges and the angles where the base and sides join together, and make sure it's pressed and compacted. This will help when removing the pie from the pan.
Bake for 10 minutes, until lightly golden and dry. Let cool completely on a wire rack before filling.
For a no-bake pie or dessert: place the crust in the refrigerator for at least 1 hour to allow the butter to firm up. This will make it less sturdy and might crumble here and there when you cut it.
