Preheat oven to 350 degrees and line an 8×8 baking dish with parchment paper
In a large bowl, mix together the graham cracker crumbs with coconut oil
Add the mixture to the baking dish and press down firmly to make the base
Bake in oven for 20 minutes
While the base bakes, add the milk and chocolate to a microwave-safe bowl and heat in 30 second increments until fully melted (stirring the mixture in between) then mix in honey
Pour chocolate on to graham cracker base and spread evenly and sprinkle marshmallows on top
Add to freezer to set for about an hour
Broil in oven for about 1 minute on high, add to freezer again for 5 minutes then slice into bars and enjoy!
