Graham Cracker S'mores Candy

The kids have said these are YUMMEE but I think they are a little too rich. Almost went in to a sugar coma. Next time I make them I think I will only use 2 Hershey Bars.

Ingedients

12 sheets of graham crackers
3/4 cup butter
3/4 cup brown sugar
3 cups mini marshmallows
4 Hershey bars, broken into pieces
1 cup milk chocolate chips

Preheat oven to 350°F. Line a 15x10x1-inch jelly roll pan with aluminum foil, leaving a 1-inch overhang over the ends, and spray foil with cooking spray. Line graham crackers up on the foil so that the sides are touching.

In a medium saucepan, melt butter and brown sugar over medium heat, stirring constantly, until smooth and mixture comes just to a boil (about 4-6 minutes). Remove from heat and pour evenly over crackers. Bake 5 to 6 minutes, or until bubbly.
Remove pan from oven and immediately sprinkle mini marshmallows, chocolate bar pieces, and chocolate chips over the crackers.

Return pan to oven for another 2-3 minutes, or until marshmallows begin to soften and puff up.

Cool completely. Lift from pan using foil edges; cut into bars and enjoy!
