S'mores Cookie Bars

Let's be honest.
I find any excuse to make these cookies.
I'm obsessed. It might be a bit out of control.
But just make these and you'll understand what I'm talking about. Come be obsessed with me. We'll make each other feel better.
A bonus to these delicious treats is that they mail well. I've made them several times to mail across the States and the feedback has been nothing short of fantastic.
Just do yourself a favor and go make these. Right now.

• 11 tablespoons of butter, softened

• 3 egg whites
• 1 1/2 teaspoons vanilla
• 1 teaspoon baking soda

• 1 Hershey's bar, chopped into pieces
• 1 1/2- 2 packages of graham crackers, broken into pieces

Preheat oven to 375.
Beat butter and sugars until smooth. Add egg whites and vanilla. Mix in baking soda, salt, cinnamon, and flour until dough forms. Add mini marshmallows and chocolate chips. Chill dough for about 20 minutes.
Grease a baking pan. Line with the broken graham cracker pieces, covering the whole pan. Once dough is chilled, scoop tablespoonfuls onto graham cracker pieces.

Bake for about 7 minutes then take the pan out of the oven and place the broken pieces of the chocolate bar evenly over the dough. Place back in oven for 5-7 minutes or until golden brown.
Cool completely. Slice and enjoy!
