7 graham cracker sheets (all but 2 in a sleeve)
1/2 cup butter (1 stick), melted
1/2 cup peanut butter
1/2 cup brown sugar
1 egg
1 tsp baking powder
pinch of salt

1/2 cup flour (i used white whole wheat)
10 marshmallows, quartered (or use mini marshmallows)
2 Hersheys chocolate bars, broken into squares (or use chocolate chips)
remaining 2 sheets of graham crackers in the sleeve, crumbled


  1. Place 7 graham cracker sheets in a food processor and process until fully crumbled. If you don’t want to use a food processor you could smash very well by hand in a Ziploc bag and pour into a bowl.
  2. Add melted butter, peanut butter, brown sugar, and egg and process to combine.
  3. Add baking powder, salt, and flour, pulse to combine until loose ball forms.
  4. Transfer to a 9×9 pan lined with parchment paper.
  5. Bake at375 for 8 minutes.
  6. Remove from oven, top with marshmallows, chocolate pieces, and crumbled graham crackers. Press down lightly on the top to push toppings lightly into crust.
  7. Bake 7-8 more minutes or until marshmallows reach desired brownness.
  8. Let cool and then cut in the pan. Bars will crumble on the edges when cut but should hold together to eat. Top with ice cream if desired.


In a box of graham crackers there are usually 3 individually wrapped sleeves. Each sleeve has 9 sheets. A sheet is a graham cracker (the one that can be broken in half or into 4 pieces) You need one sleeve for the recipe. 7 sheets will go in the bars and 2 will be crumbled on top.

These can be made in a bowl if you don’t want to use a food processor. You just have to smash the graham crackers really well.
