Brown Butter Smores Cookie Bars are made with a graham cracker cookie dough, melty dark chocolate, marshmallow, and topped with more brown butter cookie dough.
In a medium saucepan, brown the butter over medium heat. Continue cooking until the butter foams and the milk solids turn golden brown. Remove from the heat immediately to prevent burning. Pour the browned butter mixture into a large mixing bowl.
Allow the butter to cool until it is warm to the touch but not hot. Add the brown sugar and white sugar and mix until combined. And then the eggs one at a time, mixing after each addition until just incorporated.
Mix in the baking soda, baking powder, and salt and mix until evenly distributed. Fold in the flour and graham cracker crumbs and fold everything together with a spatula until a soft cookie dough forms. Be careful not to overmix.
Line an 8x8-inch baking pan with parchment paper. Press about two-thirds of the cookie dough evenly into the bottom of the prepared pan.
Sprinkle the mini marshmallows evenly over the dough, followed by the chocolate. Take the remaining cookie dough and place small pieces of dough over the top of the marshmallows and chocolate. The top does not need to be completely covered.
Bake in a preheated 350°F oven for about 30 minutes, or until the edges are golden brown and the center is set.
Remove from the oven and allow the bars to cool on a wire rack to before slicing.
Serve as is or warm a slice for a few seconds in the microwave and top with a scoop of vanilla ice cream.
