Add the chocolate, juice from one mandarin orange and coconut oil to a double boiler. Melt everything together, stirring often until a thick fudge forms. You can always add a touch more coconut oil or almond milk to get the consistency you prefer.
Add the fudge to a silicone pumpkin mold and let freeze for at least 3 hours.
Meanwhile, carefully cut graham crackers into house shapes. I suggest using a sharp serrated knife.
Create the orange frosting by adding the yellow and red food coloring to the vanilla frosting. Stir to form orange color.
Begin to build the houses! Pro tip: the more frosting the better.
Take the chocolate pumpkins from the freezer.
Decorate, have fun and enjoy!
