Creating this amazing Cranberry Eggnog Bread Pudding can be straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare Bread: In a large mixing bowl, combine the cubed bread with melted butter, tossing to coat.
3. Mix Wet Ingredients: In another bowl, whisk together the eggnog, milk, eggs, sugar, vanilla extract, cinnamon, and nutmeg until fully combined.

6. Transfer to Baking Dish: Spoon the bread mixture into the greased baking dish, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 40-45 minutes, or until the center is set and the top is golden brown.
8. Cool: Remove from the oven and allow to cool for 15-20 minutes before serving.
9. Dust with Powdered Sugar: For a final touch, dust with powdered sugar if desired.
