Crispy French Toast Waffles

Heat the waffle iron according to its manufacturer's guidelines to achieve optimal temperature.

Combine milk, eggs, maple syrup, vanilla extract, and salt in a large mixing container and blend until everything is fully incorporated. Submerge one slice of brioche into the mixture and press it gently to ensure both sides are evenly coated. Use a slotted spoon to lift the bread from the bowl, allowing any excess mixture to fall back into the container. Place the coated brioche on a rimmed baking sheet and repeat with the remaining bread, allowing each slice to absorb the mixture for about 2 minutes.

Prepare the waffle iron by spraying it with cooking spray. Place one slice of brioche onto the preheated waffle iron and carefully close the lid without pressing it down too hard. Cook until the waffles are golden brown and the iron stops emitting steam, taking about 3 to 5 minutes. Continue cooking the remaining waffles in this manner.
