Step 1

Preheat oven to 350F.

Step 2

In a small mixing bowl, combine the graham cracker crumbs, powdered sugar, and melted butter.

Step 3

Grease a 24 cup mini muffin pan with non-stick cooking spray. Scoop the graham cracker crust mixture into the 24 cups. Gently press the crumbs into the bottom of each cup and up the sides to form little cups.

Step 4

Bake the mini graham cracker crusts at 350F for 4 minutes until golden brown.

Step 5

Cut each marshmallow in half to make 24 round marshmallows. Place one marshmallow in each graham cracker cup, cut side of the marshmallow facing down.

Step 6

Set the oven to broil. Place the pan of s'mores in the oven under the broiler and broil for 1-2 minutes, just until the marshmallows are soft and beginning to look toasted. Note: the marshmallows can burn fast, so watch them very closely.

Step 7

Top each marshmallow with one piece of the Hershey's Chocolate Bar. Allow the s'mores to cool for 15 minutes, then use a butter knife to lift them from the pan.
