Preheat the Air Fryer: Preheat your air fryer to 320°F (160°C) for about 5 minutes. This ensures it’s at the right temperature when you put the muffins in.
Prepare the Batter:
In a mixing bowl, whisk together the flour, sugar, salt, and baking powder.
In another bowl, whisk together the milk, vegetable oil, egg, and vanilla extract until well combined.
Pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix; a few lumps are okay.
Gently fold in the blueberries.
Fill the Muffin Cups:
Line your air fryer basket or muffin tin with liners.
Fill each muffin cup about 2/3 full with the batter.
Air Fry the Muffins:
Place the muffin tray or basket into the preheated air fryer.
Cook the muffins at 320°F (160°C) for about 12-15 minutes or until a toothpick inserted into the center comes out clean.
Check on them periodically to ensure they’re not browning too quickly. If they are, you can cover them loosely with foil.
Cool and Enjoy:
Once done, carefully remove the muffins from the air fryer and let them cool in the muffin tin for a few minutes.
Transfer the muffins to a wire rack to cool completely.
Enjoy your delicious, soft air fryer blueberry muffins!
