Preheat oven to 180°C / 350°F (or 160°C / 320°F for fan oven).
Mix coconut flour, almond flour, psyllium husk powder, and baking powder in a bowl.
Add warm water and olive oil, stir to form dough, then knead for 1 minute.
Shape dough into ball, cut into 4 wedges, roll into balls, and place on baking tray.
Cover with parchment, roll into flatbreads (½ cm thick), shape edges, sprinkle with sesame seeds.
Bake 20-25 minutes until golden and puffy; pierce air bubbles if needed. Rotate tray for even browning or use grill/broiler for crisp top if desired.
