S'Mores Bars with M&Ms and Graham Cereal

Author TheSpicedLife


  • 2 cups AP flour
  • 1 t baking soda
  • 3/4 t fine sea salt
  • 1 cup smooshed graham cereal
  • 1 cup old fashioned rolled oats
  • 1 1/2 cups light brown sugar
  • 18 T (1 cup + 2T ; 2 sticks) unsalted butter, cut into tablespoon-sized pieces
  • 1 cup semi sweet chocolate chips
  • 2 cups mini marshmallows, divided
  • 1/2 cup lightly scooped and intact graham cereal squares
  • 3/4 cup M&Ms


  1. Preheat the oven to 350 F.
  2. Prepare a 9X13 baking pan by lining it with parchment paper that overhangs the sides of the pan (a light coating of oil in the pan will help it to stick).
  3. Whisk together the flour, baking soda and salt. Place in the bowl of a stand mixer.
  4. Measure the graham cereal by scooping 1 measuring cup of it. Press with your hands to break and flatten. Repeat until the cup is full. Add this to the flour mixture, and the rolled oats and brown sugar as well.
  5. Mix on medium speed to mix all of this together.
  6. Add the butter, a piece at a time while mixing on medium low, until it is combined and crumbly, the butter pieces no larger than the size of a pea. You may need to finish this by hand, rubbing the butter pieces into the mixture.
  7. Dump half of this mixture into the pan. Spread it out evenly and then press firmly into the pan.
  8. Bake for 12 minutes.
  9. Remove the pan from the oven and sprinkle the chocolate chips and 1 cup of the mini marshmallows evenly over the pan. Then sprinkle the rest of the oat mixture over this by clumping and then sprinkling with your hands--make sure it covers the pan evenly. Sprinkle the M&Ms and graham cereal squares over this.
  10. Press the topping lightly to make sure it adheres.
  11. Bake for an additional 16-18 minutes, until turning light golden brown.
  12. Remove the pan and sprinkle the remaining 1 cup of mini marshmallows over the top.
  13. Switch the oven to broil and place the pan back in the oven. Broil until the marshmallows are puffed, melty, and golden brown (just a few minutes, so keep an eye on it!).
  14. Cool completely before removing by the overhanging parchment to a cutting board to slice. Be warned--these bars are messy but worth it.
