Challah makes some of the best French toast because of its spongey texture and buttery flavor. Buy a round loaf or long braided loaf of it to use for French toast — a great way to utilize leftover bread from any meal.
Whisk the eggs, milk, and spices together until just frothy. Melt half the butter in a large skillet and, working in batches, soak the bread briefly in the egg mixture, turning over so both sides are coated.
Shake off any extra liquid and place on a griddle over medium heat. Cook 4-5 minutes on each side until golden brown. Dust with confectioners' sugar and top with pure maple syrup.
