Start by making your french toast batter in a mixing bowl, mix together the sugar, cocoa powder, salt, milk, eggs and vanilla extract.
Cut the challah bread (if not already cut) into slices, the thickness will depend on how you like it, I cut mine rather thick.
Then place the sliced challah bead into the french toast batter, and let it soak 5 minutes per side.
Then spray an air fryer safe pan with non-stick cooking spray, which will make it easier for you to flip.
Set the temperature to 400 degrees F. (or 390 F, if you air fryer only goes up that high) for 4 minutes. Then flip and do another 4 minutes.
Note: The actual cooking time for your french toast will depend on the thickness, the wattage of your air fryer and the degrees that you have it on. 390 vs 400. Please check and make sure that it's fully cooked.
Remove from the air fryer, garnish as you wish.
Plate, serve & enjoy!
