Add the eggs, banana, milk, cinnamon, vanilla extract to a blender and blend until smooth. Alternatively, you can mash the banana in a shallow dish and whisk in the remaining ingredients.
Add 1 tablespoon of coconut oil or butter to a non-stick frying pan set over medium heat. Alternatively, you can use nonstick cooking spray.
While the coconut oil or butter melts, carefully dip a slice of bread in the egg mixture and then flip to make sure you coat both sides of the bread. Leave the bread in the mixture for about 10-15 seconds.
Place the coated bread slices in the hot skillet and cook until golden brown and crispy on each side, about 2-3 minutes per side. Repeat with more slices. You should be able to get about 8 slices depending on the type of bread you use.
Top with fruit of choice, yogurt, nut butter, and/or a drizzle of maple syrup, if desired!
