Combine the cinnamon and sugar for the topping in a small bowl. Set aside.

Preheat your oven to 350°F. Prepare a 12-cup muffin tin with nonstick spray.

In a large bowl, beat the eggs, then add in the milk, sugar, vanilla, cinnamon, allspice, and nutmeg. Mix until well combined.

Add the bread cubes to the egg mixture, ensuring all pieces are well-coated.

Spoon the mixture evenly into the muffin tin cups. Sprinkle the reserved cinnamon-sugar topping over each muffin.

Bake for 25-30 minutes, or until the tops are lightly golden and set.

Let the muffins cool slightly before serving. Enjoy with a drizzle of syrup!
