Grind the oats finely to make oat flour.
Mix whole wheat flour, oat flour, baking powder, and salt in a bowl.
Add Greek yogurt and honey, then knead into a dough.
Roll out the dough thinly and slice it into long strips.
Twist the strips into a braided breadstick shape.
Place parchment paper in the air fryer and arrange the twisted dough pieces on top.
Bake in the preheated air fryer at 180°C (356°F) for 10–12 minutes.
Brush the remaining honey over the baked breadsticks to finish.
