Step 1

Preheat the oven to 350F and grease a 24-cup mini muffin tin with cooking spray.

Step 2

To make the graham crust, combine the finely ground cracker crumbs, a pinch of salt, sugar, and melted butter. Stir in until the crumbs are coated and begin to stick together.

Step 3

In spoonfuls, transfer the crumbs to the prepared muffin tin, evenly distributing between 24 cups. Gently press the crumbs into the bottom and up the sides of the crust. Bake for 4 to 5 minutes, or until nicely golden.

Step 4

Remove the crusts from the oven, top with 3 or 4 chocolate chips and a halved marshmallow, cut side down.

Step 5

Set the oven to broil and return the cookie cups to the oven. Broil for 1 to 2 minutes, or until toasted just the way you like them.

Step 6

Remove from the oven and immediately to each marshmallow with a chocolate square. Let sit about 15 minutes before removing the cookie cups from the tin with a table or butter knife.
