In a large bowl, mix together the almond flour, coconut flour, melted coconut oil, maple syrup, vanilla extract, cinnamon, and sea salt until a crumbly dough forms.
Press about 2/3 of the mixture into the bottom of the prepared baking dish.
Bake the crust for 10 minutes.
Remove the pan from the oven and spread the almond butter over the warm crust.
Sprinkle the dark chocolate chips evenly over the crust, followed by the marshmallows.
Crumble the remaining dough mixture over the top.
Bake for another 10 minutes, or until the marshmallows are golden and the chocolate is melted.
Let the bars cool for at least 20 minutes before slicing.
Notes
Chef Tips:
Use high-quality dark chocolate for the richest flavor.
Let the bars cool fully before slicing for cleaner edges.
For extra toasted marshmallow flavor, broil the bars for 1 to 2 minutes at the end.
Store leftovers in an airtight container so the bars stay soft and chewy.
