Preheat griddle to 350 degrees F or heat a skillet over medium heat.
Add all ingredients, except the bread, to a blender or to a shallow dish and whisk well to combine. If whisking by hand, it's okay if the flour doesn't mix in completely smooth.
Grease skillet with butter or non-stick spray. Dip the bread in the batter and turn to generously coat both sides.
Place on hot skillet and cook for a few minutes, until the bottom of the bread starts to get golden brown. Flip and cook on the other side the same.
Make Ahead Instructions: The batter can be made a day ahead of time, stored in the fridge.Freezing Instructions: Allow cooked French Toast to cool completely, then place in freezer safe bag or container and freeze for up to 3 months.
