1/2 cup butter (one whole stick)
1 1/2 cups graham cracker crumbs ***if you are making this with gluten free graham crackers I feel like you will need 2 cups.***
1 cup semi-sweet chocolate chips (L and I were in a chocolate kind of a mood today, so we used 1 1/2 cups)
1 can (14 oz.) sweetened condensed milk
1 1/2 cups miniature marshmallows
Preheat oven to 350 degrees. While oven is preheating, cut butter into chunks and place them in 9x13" baking pan. Place pan into oven until butter is melted.
Once butter is melted, take pan out of oven and sprinkle graham cracker crumbs evenly over the melted butter. Evenly sprinkle chocolate chips over crumbs. Then evenly pour sweetened condensed milk over the chips and crumbs. And place in the oven for 20 to 25 minutes. (The condensed milk will get all bubbly on the sides of the pan but have no fear.)
Remove pan from oven and evenly sprinkle marshmallows Return to oven for 2-5 more minutes. ***At this point I turn my broiler on and carefully let the marshmallows brown. But that is just our personal preference***
Allow bars to completely cool before you cut them with a sharp knife. (I know that is a hard step but they will not cut right unless the bars are totally cooled.) Then enjoy the gooey chocolaty, marshmellow-y, carmel-y goodness!
