1. Preheat your air fryer to 320°F (160°C). This ensures even baking.

2. Prep your ingredients: Grate 1 ½ cups of fresh carrots and set aside. In a mixing bowl, combine 1 ¼ cups flour, 1 teaspoon baking soda, 1 teaspoon baking powder, 1 teaspoon ground cinnamon, and ½ teaspoon salt.

3. In another bowl, beat 2 eggs. Add ⅔ cup oil and ¾ cup sugar. Mix well until combined.

4. Combine the wet and dry ingredients: Gradually add the dry mixture to the wet mixture. Stir until just combined. Avoid overmixing.

5. Fold in the grated carrots. If using, add ½ cup chopped nuts and ½ cup raisins. Mix gently to distribute evenly.

6. Prepare the muffin cups: Place silicone or paper muffin cups in the air fryer basket. Fill each cup about two-thirds full with the batter.

7. Bake in the air fryer: Cook the muffins at 320°F (160°C) for 15-18 minutes. Check for doneness by inserting a toothpick into the center of a muffin. If it comes out clean, they are done.

8. Cool the muffins: Allow them to cool in the basket for 5 minutes, then transfer to a wire rack to cool completely.
