In a large mixing bowl mix together the 1 cup graham cracker crumbs, 2 tablespoons powdered sugar and melted 6 tablespoons butter
Mix well.
Spray your muffin tin, with olive oil spray.
Press the crust into the greased muffin tin, and then use your fingers to really press it in.
Set into the air fryer for 7-12 minutes, at 300 degrees F, just long enough for the graham cracker to brown.
Cut the marshmallows in half and press into the cookie cup.
Set the pan again into the air fryer, this time you will broil the marshmallows for about 2 minutes. As soon as they get brown, remove.
Press the chocolate square into the center of the marshmallow, and let cool for about 20 minutes, before removing them from the tray.
