Place bread slices flat on a sheet pan. Bake at 250F for 15 minutes, flipping halfway through.
In large shallow bowl, whisk together remaining ingredients.
Taking one bread slice at a time, dip bread into egg mixture and coat both sides.
In large skillet, melt 2 Tbsp. butter or use nonstick pan. Place the soaked bread into the skillet and cook 2-3 minutes each side or until golden brown.
Repeat with remaining slices and serve with maple syrup.
