Preheat air fryer to 325°F.

In one bowl, mix oat flour, protein powder, baking powder, and cinnamon.

In another bowl, whisk the egg, oat milk, maple syrup, and vanilla.

Stir wet into dry mixture until smooth, then fold in the diced peaches.

Lightly spray four 6-ounce ramekins and divide the batter evenly.

Air fry at 325°F for 12–14 minutes, or until golden and cooked through.

Let cool slightly. Serve warm — optionally with a dollop of Greek yogurt or cinnamon drizzle.
