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

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.
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.
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.

The first tip I have is to use the normal WHITE mini marshmallows!! The colored/flavored ones taste a little funny with this recipe. In my defense, I wasn't aware they were flavored...I just saw the fun colors and threw them in my buggy (yes I say buggy..I'm from the south and that's how we roll!). My next tip is to be very careful while toasting the top....my smoke alarm went off and that's all I'm gonna say about that!! :)

Enjoy!! :)
