01 - Preheat oven to 425°F. Line a baking sheet with parchment paper and set aside.
02 - Steam or boil the cubed sweet potatoes until fork-tender, approximately 10–12 minutes. Drain thoroughly and mash until completely smooth.
03 - In a large mixing bowl, combine the mashed sweet potato, egg, almond flour, Parmesan cheese, garlic powder, salt, and black pepper. Mix until the mixture is uniform and well incorporated.
04 - Spread the sweet potato mixture onto the prepared baking sheet, shaping it into a 12-inch round approximately 1/4 to 1/2 inch thick.
05 - Bake the crust for 20–22 minutes until firm and lightly golden on the edges.
06 - While the crust bakes, gently warm the honey in a small saucepan with the chili flakes or hot sauce and apple cider vinegar over low heat for 2–3 minutes. Remove from heat and set aside.
07 - Remove the crust from the oven. Spread the marinara sauce evenly across the surface. Sprinkle with shredded mozzarella, arrange the pepperoni slices on top, and scatter the sliced onion and bell pepper if desired.
08 - Return the assembled pizza to the oven and bake for an additional 8–10 minutes, until the cheese is melted and bubbly and the edges are crisp.
09 - Drizzle the prepared hot honey generously over the finished pizza. Garnish with fresh basil leaves and additional crushed red pepper to taste. Slice and serve immediately.
