Beat the butter with an electric mixer until smooth, then add the sugars and mix on medium high until light and fluffy.

Step 4

Then add the egg and mix again until well incorporated.

Fold in the chocolate chips.

Step 8

Using your hands, form 2 tablespoons of the cookie dough into a flat disk.

Place six even balls on the baking tray and bake for 6 minutes.

Step 11

Remove the pan from the oven and quickly add some Hershey’s chocolate pieces, mini marshmallows and graham crackers to the tops of the cookies.

While the cookies are baking, form the rest of the cookies and set aside.
