Take your bread and slice each slice into thirds.
In a dish with walls or a bowl (I use a casserole dish), add your eggs, milk, and vanilla, Whisk together with a whisk or fork.
On a plate, combine your cinnamon and sugar and mix together until combined.
Quickly dip each slice of toast in the egg mixture on the front and back (don't let soak). Either dip the slice in the cinnamon sugar mixture or sprinkle on the front and back.
Place each slice onto the air fryer tray in a single layer, leaving room between each slice for air flow. (You will most likely have to do these in 2-3 batches, depending on the size of your air fryer)
Set your air fryer to 350 degrees F and fry for 6-8 minutes.
Serve with maple syrup, sprinkled with powdered sugar, or just as is.
