Equipment

  • electric beater
  • 9X13 pan
  • parchment paper

Ingredients
  

  • 2 1/4 c all purpose flour
  • 1/4 c finely crushed graham crackers
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 1/4 c packed brown sugar (275g)
  • 1/4 c granulated sugar (55g)
  • 1/2 c brown butter, cooled to softened butter (113g) (10tbsp unsalted butter, reduced to 8 tbsp or sub with 1/2 c softened butter)
  • 1/2 c tahini, well stirred (113g)
  • 2 large eggs, room temperature
  • 1 large egg yolk, room temperature
  • 2 tsp vanilla extract
  • 1 2/3 c chocolate chips, divided
  • 7 oz jar marshmallow creme or Fluff
  • 3/4 c roughly crushed graham crackers

Instructions
 

  • To prepare browned butter, place butter into a sauce pan over medium high heat. Butter will melt and begin to foam. Using a whisk, stir constantly. Foam will subside, brown bits will form at the bottom and the butter will have a nutty smell. Remove from heat, pour into a heat proof bowl and cool for 15 minutes to room temperature. Transfer to the fridge to chill an addtional 20-30 minutes. Butter should be soft, but not cold in order to cream. If it has turned cold, bring to room temperature for 10 minutes.
    Alernatively, prepared browned butter the day before. Bring to room temperature before baking, along with all the other ingredients.
  • In a separate bowl, whisk together flour, finely crushed graham crackers, baking soda and powder and salt. Set aside.
  • In a mixing bowl, with paddle attachment, cream together the browned butter, sugars and tahini until light and fluffy (~5 minutes). 
    Add in eggs and yolk one at a time, beating well after each. Add vanilla and beat again for about an additional minute.
    By hand, using a spatula, add dry ingredients to the wet 1/2 at a time. Mix until JUST combined. Fold in 1/3 c chocolate chips.
    Loosely cover the dough in plastic cling. Place dough in the fridge to chill for one hour.
  • Preheat the oven for at least 30 minutes. Line a 9X13 baking pan with parchment paper, leaving 1-2" of an overhang on the two longer sides. This "sling" helps to remove the bars from the pan after cooling.
  • Roughly divide the chilled cookie dough into thirds. Reserve about 1/3 for topping. Evenly press 2/3 of the chilled dough along the bottom of the prepared baking pan.
    Scoop even dollops of marshmallow creme, or fluff along the chilled dough. A spoon dipped in hot water can help. Spread the marshmallow creme evenly along the bottom. Top with 1 c of semi sweet chocolate chips (or hershey bar pieces for a more classic touch). Top the marshmallow creme and chocoate with roughly crushed pieces of graham crackers.
    Top everything with the remaining 1/3 of the chilled dough. This will not completely cover the top of the bars. Instead, scoop dough into your hand. Press it into a flat disk and place around the pan. This is similar to topping a fruit cobbler with biscuit dough. This is done so the filling pushes through. Top with the remaining 1/3 c chocolate chips if desired.
    **For more solid looking bars, use 1/2 dough for the base and 1/2 for the topping. Try to press the pieces of dough together, covering all the filling.
  • Bake in a 350F oven for 25-32 minutes or until golden brown with set edges pulling slightly from the edge of the pan.
    At 25-28 minutes, the edges will be baked and the center will be slighlty underbaked. This is my prefered way. For more well baked bars, bake 28-32 minutes.
    Cool pan on a cooling rack for 45-60 minutes. Bars are cool enough to eat at 30 minutes, but they will not be firm enough to lift out of the pan until closer to an hour.
    Using the sling, remove bars from the pan, slice and enjoy!
