Preheat griddle to 350 degrees F or heat a skillet over medium heat.

Make batter: 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 to be completely smooth.

Cook: Grease griddle with butter. Dip bread slices into the egg mixture, dredging them well on both sides, and place on hot pan. Cook for a few minutes, until the bottom of the breads starts to get golden brown. Flip and cook on the other side the same.

Serve warm with syrup and a sprinkle of powdered sugar.
