Preheat the oven to 350 F.

In a mixing bowl, whisk together egg, almond butter, maple syrup, and melted coconut oil.

In a separate bowl, combine almond flour, coconut sugar, baking soda, and salt. If needed, sift the almond flour to make sure there are no lumps left.

Gently combine the wet and dry ingredients together with a spatula.

Fold in 3/4 of the chocolate chips or chopped chocolate bars into the cookie dough. Save the rest of the chocolate for later.

Grease an 8 or 9 inch cast iron skillet with coconut oil. Add half of the cookie dough to the bottom of the cast-iron skillet

Then, add a layer of graham crackers (you can break them up in however large pieces you would like).

Add the rest of the cookie dough on top of the graham crackers.

Place marshmallows, the rest of the chocolate, and more graham crackers on top.

Bake for 17 - 20 minutes or until your preferred doneness.
