Crack the eggs into a shallow dish, like a pie plate. Add the half-and-half, vanilla, ¼ cup sugar and ½ teaspoon cinnamon. Whisk lightly until combined; set aside.
In a separate shallow dish, stir together the breadcrumbs, crushed cereal and remaining ¼ cup sugar, and ½ teaspoon cinnamon. Use a fork to stir in the melted butter.
Dunk the bread strips in the egg mixture, turning to coat. Then lay them in the dish with the crumb mixture, turning them over, sprinkling, and pressing so the crumbs totally cover the surface. Place on a lined baking sheet to either bake or flash freeze for later.
To bake, preheat the oven to 425°F. Bake until golden brown around the edges, about 10-12 minutes (15-18 minutes if baking from frozen).
