Combine the cinnamon and sugar in a small bowl to create the topping. Set aside.
Preheat your oven to 350°F and prepare a 12-cup muffin tin by spraying it with nonstick spray.
In a separate bowl, whisk together the eggs, milk, sugar, vanilla, cinnamon, allspice, and nutmeg until well combined.
Fold in the cubed bread, ensuring each piece is coated with the mixture.
Divide the bread mixture evenly into the prepared muffin tin cups, then sprinkle each with the cinnamon-sugar topping.
Bake in the preheated oven for about 25 minutes or until the tops are golden and set.
Once done, remove from the oven and let them cool slightly. Serve with your favorite syrup for an extra touch of sweetness. Enjoy!
