In a quart-sized mason jar, combine the eggs, milk (or cream), vanilla extract, and cinnamon.
Secure the lid tightly on the mason jar and shake it up! Give it a good shake to mix everything together evenly.
Once the mixture is ready, store it in your cooler or RV fridge until you're ready to use it. It’s the perfect make-ahead breakfast, and it takes up hardly any space!
When you’re ready to cook, simply grab your bread and dip it into your egg mixture. Then, cook your French toast however you like — on a skillet over the campfire, in a pie iron, or even in foil packets. For a skillet French toast, melt some butter over the fire, cook each side of the bread until golden brown, and then drizzle with syrup.
Once your French toast is cooked to perfection, add your favorite toppings!
