Ingredients

• 1 box (15.25 oz) yellow or spice cake mix

• 1 1/4 cups eggnog

• 1/2 cup (1 stick) butter, melted

Optional add-ins: 1/2 teaspoon ground nutmeg, 1 teaspoon vanilla extract, 2 large eggs, and a simple eggnog glaze for drizzling.

Directions

1. Lightly grease the insert of a slow cooker.

2. In a large bowl, whisk together the cake mix, eggnog, melted butter, and eggs and vanilla if using until smooth and evenly combined. Stir in the nutmeg if desired.

3. Pour the batter into the prepared slow cooker, smoothing the top with a spoon or spatula.

4. Cover and cook on LOW for 2 to 2 1/2 hours (or on HIGH for 1 to 1 1/2 hours), until the center is set and a toothpick inserted in the middle comes out clean.

5. Let cool 15 minutes, then drizzle with an eggnog glaze if desired and serve warm.

Serving Ideas

This cake is lovely served warm with a dusting of powdered sugar, a spoonful of whipped cream, or a drizzle of eggnog glaze. For a cozy holiday dessert plate, pair it with a cup of coffee or hot cocoa, or serve it alongside fresh fruit and toasted pecans.

Variations & Tips

• Cake Mix Swap: Spice cake mix adds extra warmth, while yellow cake mix keeps it milder.

• Eggnog Tip: Use full-fat eggnog for the richest flavor and tenderest crumb.

• Add-Ins: A handful of dried cranberries or chopped pecans stirred into the batter adds extra texture and festive flavor.

• Storage: Cover leftovers tightly and refrigerate up to 4 days; a few seconds in the microwave brings back that fresh-from-the-oven warmth.
