In a small bowl whisk together the eggs, milk, cinnamon, and vanilla.
Spray the bottom of the basic air fryer with olive oil spray. Cut the Texas toast into 3 sections. Dredge into the egg mixture and place in a single layer in the basket. Sprinkle the tops with brown sugar.
Cook at 360 degrees for 6-8 minutes or until golden. Serve with syrup and dust with powdered sugar if desired.
