Preheat your oven to 425°F. While the oven heats, mix olive oil, garlic powder, cayenne pepper, and smoked paprika together in a small bowl. Lightly brush this mixture over the top of the flatbread, ensuring the edges are covered too. This flavorful base makes all the difference.
Scatter the cooked chicken evenly across the flatbread. Sprinkle on the spinach leaves, ensuring they’re well distributed. Next, top it all with shredded mozzarella. The cheese will melt beautifully, holding all the flavors together.
Place the flatbread directly on the oven rack or use a baking sheet for easy handling. Bake for 8-10 minutes until the cheese is melted and golden, and the edges of the flatbread are crisp.
While the flatbread is baking, prepare the spicy-sweet drizzle. Combine honey, olive oil, chili flakes, garlic powder, and cayenne pepper in a microwave-safe bowl. Heat the mixture in the microwave for 15-20 seconds. Stir it well to blend the flavors evenly.
After baking, slice the flatbread into pieces and drizzle the warm hot honey sauce generously over the top. You can make extra sauce for dipping if you like, which takes the flavors even further. Serve immediately and enjoy!
