Totally stole this from gimme some oven via notmartha.org. Maybe borrowed is the better word.
Anyway, after you made cookies but before you leave:
put a bunch of sticks into large marshmallows
crush a bunch of graham crackers into little pieces and put into a shallow bowl
melt a bunch of semi-sweet chocolate in another bowl
1. Dip marshmallow-on-a-stick into chocolate, using a spoon to help spread a thin layer of chocolate all over, including all around where the stick goes in.
2. Dip chocolate-covered-marshmallow-on-a-stick into the graham cracker crumbs, pressing in on each side to pick up biggish pieces, and a spoon to coat the top.
3. Place on parchment paper, or a serving type platter.
(optional)4. Refrigerate or put into treat baggies or both.
Definitely a good crowd pleaser easy dessert. The sticks and the bags I have on hand, so those aren't counting towards the total costs. I think it'd be about $5ish. Used generic low-fat grahams (albertsons, <$2), generic marshmallows (albs, $1.50), and tollhouse semi-sweet chips (albs or vons $1.88 right now). Used about 1/6 the grahams, 1/2 the mallows and 1/2 the chips.
Anyway. Probably not the healtiest thing ever, but delicious!
