Line a baking sheet with parchment paper and grease it lightly.
Preheat oven to 400 degrees F.
Place sweet potato chunks and coconut flour in the food processor and blend until the mixture becomes a fine texture.
Add egg, olive oil, sea salt, and garlic powder, and pulse until the dough becomes pasty.
Scoop out 2 tablespoons of the dough on the parchment paper and use your hands to shape into a circular crust that's about 1/4 - 1/2 inch thick. Repeat with the rest of the dough.
Bake in the oven for 15 minutes.
While the crust is baking, make the cashew cheese by blending all ingredients in a blender until smooth and creamy. Add more water if the consistency is too thick.
Once the crust is done baking, top with 1 tsp marinara sauce.
Add the cashew cheese (you might not use all of it), then top with a slice of pepperoni.
Add black olive slices, or for Halloween, cut the olives into shapes for spiders before adding them.
Place back in the oven and bake for another 5 minutes.
Sprinkle with your favorite toppings, then enjoy!
