Preheat oven to 350°F. Line a 9x13 pan with parchment paper.
In a large bowl, mix eggs, melted butter (or coconut oil), coconut sugar, and vanilla until creamy.
Add baking soda, salt, almond flour, and coconut flour. Stir until a dough forms.
Fold in the crushed graham crackers.
Press ¾ of the dough into the pan to create the bottom layer.
Spread marshmallow cream or mini marshmallows evenly over the dough.
Sprinkle most of the chocolate chips on top.
Drop spoonfuls of the remaining dough over the top and gently press. Leave some gaps!
Sprinkle with remaining chocolate chips.
Bake for 30–35 minutes, or until golden on top and set around the edges.
Let cool for 10–15 minutes before slicing for neat bars (or dig in warm and gooey!).
