In a mixing bowl, whisk together the 2 large eggs, 1 tablespoon of whole milk, 1 tablespoon of maple syrup, 1 teaspoon of pure vanilla extract, and 1/2 teaspoon of ground cinnamon until well combined.
Take your 4 slices of brioche and cut them into strips, about 1 inch wide.
Dip each brioche strip into the egg mixture, ensuring that both sides are coated. Allow any excess mixture to drip off.
Preheat your air fryer to 370°F (188°C) for about 5 minutes.
Place the dipped brioche strips in a single layer in the air fryer basket, making sure not to overcrowd them.
Air fry the French toast sticks for 8-10 minutes, flipping them halfway through the cooking time.
Remove the French toast sticks from the air fryer and serve warm with toppings.
