Start by mixing the bottom layer, in a large mixing bowl, mix together the fresh or frozen blueberries, flour, and sugar. Making sure that all of the blueberries are coated.
Then spray an air fryer safe pan with olive oil, and spread the bottom layer into the pan. Depending on the size of the pan, you may make 2 of them (as I did)
Then in another bowl mix together the cobbler, the fl our, sugar, baking powder, ground cinnamon, egg, and milk. Mix well together.
Drop the cobbler over the bottom layer.
Then place the pan in the air fryer basket or in the air fryer oven. Set the temperature to 330 degrees F, for 10 minutes.
Remove once golden on top, let cool, before serving.
Plate, serve and enjoy!
