Prepare the spring-form pan by placing parchment paper at the bottom and lightly spray the paper and sides of the pan with cooking spray. You can line the sides with parchment papers as well, but I found that to be unnecessary.
Melt the butter (the flavor of the crust can be more toasted if you brown the butter. To do this, stir the butter over medium heat. It will start to bubble and then the bubbling will go back down. It should start to brown shortly thereafter).
Put the graham cracker crumbs in a medium bowl.
Mix the cinnamon into the graham cracker crumbs.
Add the melted butter into the bowl and mix with a whisk until moistened.
Place graham cracker crust mix into the spring form pan.
Press the crust around the pan evenly using the bottom of a flat cup. (Note: I prefer a thicker, flat crust so that there is an equal amount of crust in each bite. If you wish to have the crust go up the sides, you can do so by pressing the crust against the sides of the pan, but your crust will be thinner.)
