If the bread is not stale, let it sit on a baking sheet for an hour or so to harden it up a little bit.
In a shallow bowl, whisk the eggs & yolks, milk, sugar, cinnamon, salt and vanilla, until foamy and smooth. Set aside.
Heat a large nonstick skillet over medium heat.
Place a small amount of butter (enough to coat the bottom of the skillet when melted) in the skillet and melt.
Place 1 or 2 slices of bread at the time in the bowl with the egg mixture, turning, until saturated. Do not soak!
When butter is just melted and bubbling, add bread slices in batches, cooking until they’re golden brown and crisp, a couple of minutes per side.
Serve immediately, or transfer to the oven to keep warm while cooking remaining bread.
Top with maple syrup, berries, jam, sliced bananas, or whatever you'd like.
