Beat butter and sugar until creamy.

Add eggs and vanilla. Mix well.

Add dry ingredients.

Add chips.

Chill 30 mins.

Scoop with a large scoop. (1⅞ ounces dough is what I use for each cookie.)

Bake at 300 degrees on parchment or silpat (convection if you have it) for 15-18 minutes.

Remove from oven and remove to wire rack to cool.

Once cool, top each cookie with a few marshmallows.

Broil carefully to brown-do not walk away-watch closely!

Cool again, then dip in chocolate and sprinkle on the graham cracker crumbs.

Let set.
