In a wide, shallow bowl, crack each of the eggs and whisk them together.
Add the milk, cinnamon, and vanilla to the eggs and thoroughly whisk all the ingredients.
Lightly spray your air fryer basket with cooking oil. Then, doing so one slice at a time, dip the brioche bread in the egg mixture, coating both sides of the bread.
Next, place as many pieces in your air fryer basket as you can without overlapping slices.
Air fry at 350°F for 3-5 minutes, flip each piece, then air fry for an additional 3-5 minutes until golden.
Top with your favorite toppings like fresh berries, powdered sugar, whipped cream, or syrup, and enjoy!
