Slice FOUR 1" thick slices of challah bread. Set slices aside.

Put eggs, milk, cinnamon and vanilla in a shallow bowl (large/wide enough to lay a bread slice in it flat. Use whisk or fork to mix into a wet batter. Set aside.

Put Raisin Bran Crunch (REMOVE RAISINS) in a food processor; pulse until they become much smaller flakes. No food processor? Put cereal in a large plastic storage bag. Seal bag, lightly pound cereal with rolling pin or meat mallet until flakes are crushed into smaller pieces.

Place bowls (egg batter on the left/crunchy topping on the right) on kitchen counter, side by side.

Place 1 bread slice into egg batter. Once bottom side is coated, flip bread over, coat other side. Gently press bread into the batter, to ensure it's fully covered. Lift bread up; let excess batter drip down into the bowl. Immediately place bread into the crunchy topping Cover one side of the bread; flip and cover other side with topping. Repeat until all slices are covered (both sides) with batter and topping. Lay slices on parchment paper (or wax paper) while coating other slices.

Preheat air fryer to 370℉. Lay bread slices in the inner basket in single layer, leaving space in between each slice (for best air circulation). Cook at 370°F. for 5 minutes. Once done (5-6 minutes) the French toast should be lightly browned on top, cooked through, and crispy on the outside.

Use a spatula to transfer French Toast out of the air fryer onto serving plates. Serve immediately, garnished with favorite toppings (butter, syrup, powdered sugar, fruit, etc.). Enjoy!
