I found a pretty simple recipe from BettyCrocker.com (http://www.bettycrocker.com/recipes/warm-toasted-marshmallow-smores-bars/902bb288-e52b-4aba-a264-925d20f37d98)
1 pouch (1 lb 1.5 oz) Betty Crocker® sugar cookie mix
1 cup graham cracker crumbs
1 cup butter or margarine, melted
3 cups milk chocolate chips (18 oz)
4 1/2 cups miniature marshmallows
1 ) Heat oven to 375°F. In large bowl, stir together cookie mix and crumbs. Stir in melted butter until soft dough forms. Press into ungreased 13x9-inch pan.
2 ) Bake 18 to 20 minutes or until set. Immediately sprinkle chocolate chips over crust. Let stand 3 to 5 minutes or until chocolate begins to melt. Spread chocolate evenly over crust.
3 ) Set oven control to broil. Sprinkle marshmallows over melted chocolate. Broil with top 5 to 6 inches from heat 20 to 30 seconds or until marshmallows are toasted. (Watch closely; marshmallows will brown quickly.) Cool 10 minutes. For bars, cut into 6 rows by 4 rows. Serve warm. Store any remaining bars tightly covered.
I ended up not following exact measurements for the chocolate chips and marshmallows and just went with what looks like a good amount for both. It was really fun using the broiler and browning the marshmallows too. I'd like to put that part of the oven to use a bit more.
The bars turned out pretty well. Once they cool though, the marshmallows get a little harder and weren't as easy to cut. The crust is definitely the best part of the bars. It's buttery and sweet and just YUM. I like this recipe. If I make it again I'll try to figure out a way for each of the layers to be a bit more blended together.
