Instructions

Preheat your oven to 350°F. Line an 8×8-inch baking pan with parchment paper and set it aside.
In a large bowl, cream together the butter, brown sugar, and granulated sugar until smooth. Add the egg and vanilla extract, then mix until fully incorporated.
½ cup butter, ⅓ cup brown sugar, ¼ cup granulated sugar, 1 egg, 1 teaspoon vanilla extract
Next, stir in the flour, crushed graham crackers, salt, and baking soda. Mix just until no dry streaks remain.
1½ cups all-purpose flour, ½ cup graham cracker crumbs, ¼ teaspoon salt, ¾ teaspoon baking soda
Press half the cookie dough evenly into the bottom of the prepared pan. Lift the parchment out and chill that layer in the fridge. Re-line the pan with fresh parchment, press in the remaining dough, and chill this second layer as well.
Place the first dough layer back into the pan. Top it with chocolate bars, breaking them as needed to cover the surface. Spread marshmallow fluff over the chocolate, then carefully flip the second chilled dough layer on top, gently pressing the edges to seal without cracking.
5 standard Hershey bars, 1½ cups marshmallow fluff
Bake for 25 minutes, until the top is golden. Cool completely before slicing to reveal those gooey, gorgeous layers you’ll fall in love with.
