Preheat a griddle pan on medium-low and spray generously with cooking spray.
While the pan is heating up combine the egg, half and half, cinnamon, and vanilla extract in a shallow plate/bowl. Whisk together until fully incorporated.
Cut the baguette into 1-½ to 2 inch pieces. Place a few pieces in the milk mixture and let sit for a few seconds. Turn over the baguette and let it sit for an additional 5 seconds.
Add soaked baguette pieces to the hot pan and cook on medium-high for a few minutes or until the pan side down is browned but not burnt. Turn them over and repeat for an additional minute or two.
Plate the french toast and sprinkle powdered sugar over the top of the dish. Add a pat of butter and serve with syrup if desired.
Crispy French Toast - Use 1-2 tablespoons of coconut oil per batch of french toast you fry. This will give the crispiest outside with keeping the center soft!
No Stale Bread? If you don't have stale bread, simply slice the baguette into 1-inch thick slices and let sit out on the counter 30-60 minutes until it starts to harden up. Note: you will not need to soak the bread as long if it isn't stale.
