Peel apples (optional) and cut them into fry-like sticks.
Pat the apple slices dry with a paper towel to help the coating stick properly.
Set up three bowls: add all-purpose flour to the first bowl, non-dairy milk to the second bowl, and combine panko breadcrumbs, granulated sugar, and ground cinnamon in the third bowl.
Dredge each apple stick through the assembly line: first in flour, then a quick dip in milk, and finally coat thoroughly in the cinnamon-sugar breadcrumb mixture.
Lightly spray the coated apple sticks with nonstick cooking spray.
Arrange apple fries in a single layer in your air fryer basket, working in batches if needed to avoid overcrowding.
Set air fryer to 380°F and cook for 7-9 minutes, shaking the basket halfway through cooking time.
Apple fries are done when they turn golden brown and develop a crispy exterior.
Serve warm with optional dipping sauces like caramel, vanilla yogurt, or whipped cream.
