Cut the pound cake or sponge cake into bite-sized 1-inch cubes. If the cake is very fresh and soft, spread the cubes on a sheet pan and let them sit out for 20–30 minutes so they dry slightly and can better soak up the eggnog pudding.

If using alcohol, stir together the dark rum or bourbon with about 2 tablespoons of eggnog. Lightly brush or drizzle this mixture over the cake cubes. Do not saturate them—you want just a light, flavorful coating, not soggy cake. Skip the alcohol for a family-friendly version and use plain eggnog instead if desired.

In a large mixing bowl, whisk together the instant vanilla pudding mixes, chilled eggnog, and whole milk for 2–3 minutes, until thick and smooth. Whisk in the vanilla extract, ground nutmeg, and ground cinnamon (if using). Let the mixture sit for about 5 minutes to continue thickening until it mounds softly on a spoon.
2 boxes (3.4 oz each) instant vanilla pudding mix, 3 cups chilled eggnog, 1 cup whole milk, 1 teaspoon pure vanilla extract, 1/2 teaspoon ground nutmeg, 1/4 teaspoon ground cinnamon
In a chilled mixing bowl, combine the cold heavy whipping cream, powdered sugar, vanilla extract, and a pinch of salt. Beat with a hand mixer or stand mixer on medium-high speed until soft peaks form, then continue just until medium to firm peaks hold their shape while still looking soft and glossy. Do not overwhip or the cream will become grainy.

Gently fold about 1 cup of the whipped cream into the eggnog pudding mixture using a spatula, turning the bowl as you go. Fold just until combined to keep as much air as possible. This creates a lighter, mousse-like eggnog layer.

In a large trifle bowl or clear glass bowl, add an even layer of cake cubes to cover the bottom, allowing for a few small gaps. Spoon about one-third of the eggnog pudding mixture over the cake and gently spread it to the edges.

Spread a layer of whipped cream (about one-third of the remaining whipped cream) over the eggnog pudding. Repeat the layers—cake cubes, eggnog pudding, whipped cream—aiming for about three sets of layers, depending on the height of your bowl. Finish with a generous final layer of whipped cream on top.

Right before chilling, sprinkle the top layer of whipped cream with freshly grated or ground nutmeg. Add crushed gingersnap or Biscoff cookies, white chocolate curls, and/or a ring of maraschino cherries or fresh cranberries around the edge for decoration, if desired.

Cover the trifle bowl loosely with plastic wrap and refrigerate for at least 4 hours and up to 24 hours. This chilling time allows the cake to absorb some of the eggnog pudding and lets the flavors meld.
Keep the trifle chilled until serving. Scoop down through all the layers with a large spoon so each portion includes cake, eggnog pudding, and whipped cream. Serve cold.
