Whisk together the eggs, egg whites, milk, cinnamon, and vanilla in a large shallow dish or casserole dish. If you are adding protein powder, add it in this step and whisk until completely combined.
Before dipping your bread slices, heat a large pan or pancake griddle to medium heat so it is ready to go. Grease the pan with butter or olive oil spray.
Working with two pieces of bread at a time, soak each slice in the egg mixture. Make sure to turn them over, so you coat both sides. I like to let mine soak up the mixture for about 1 minute.
Once the greased pan is hot, add the soaked bread slices to the pan and cook for a total of 4 - 5 minutes, flipping halfway through. The french toast should be golden with crispy edges. Repeat this process until you use all your bread.
Serve warm topped with a dollop of Greek yogurt, your favorite maple syrup, powdered sugar, fresh berries, and/or a dash of cinnamon. Enjoy!
