Preheat the Air Fryer: Preheat your air fryer to 350°F (180°C) for a few minutes while you prepare the muffin batter.

Prepare the Batter: In a large mixing bowl, combine the grated zucchini, flour, eggs, sugar, oil or melted butter, baking powder, cinnamon, and salt. Mix until well combined and the batter is smooth.

Fill Muffin Cups: Line the muffin cups of your air fryer basket with paper liners or silicone liners. Fill each muffin cup about two-thirds full with the batter.

Bake in Air Fryer: Place the filled muffin cups in the air fryer basket, making sure they are not overcrowded. You may need to cook them in batches depending on the size of your air fryer. Air fry at 350°F (180°C) for 12-15 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Cool and Serve: Once the muffins are baked, carefully remove them from the air fryer basket and transfer them to a wire rack to cool. Allow them to cool for a few minutes before serving.

Enjoy: Serve the zucchini muffins warm or at room temperature. They are delicious on their own or with a dollop of butter or cream cheese spread. Enjoy for breakfast, brunch, or as a satisfying snack!
