If your brioche bread is very fresh, lightly toast the slices or leave them out for a bit to help firm them up. This helps prevent sogginess when dipping.

In a shallow dish or mixing bowl, add eggs, milk, vanilla, cinnamon, and salt. Whisk until fully combined and smooth.

Heat a skillet over medium heat and coat with nonstick cooking spray. Quickly dredge one slice of brioche bread in the egg mixture, coating both sides without letting it sit too long.

Place the bread directly into the heated skillet. Because cinnamon can settle quickly into the first slice, sprinkle a little extra cinnamon directly on top of each slice after adding it to the pan to keep the flavor balanced.

Cook for 2 to 3 minutes on each side, until golden brown and cooked through. Repeat with remaining slices, working in batches as needed. Serve warm with powdered sugar and maple syrup.
