This easy Eggnog Poke Cake starts with a simple yellow cake mix soaked in creamy spiced vanilla pudding for the perfect holiday dessert. Light, fluffy, and full of warm nutmeg flavor, no actual eggnog needed!
Bake the cake. Prepare and bake the yellow cake according to package directions in a greased 9×13-inch baking dish. Let cool for about 10 minutes until warm but not hot.
Poke holes. Use the handle of a wooden spoon to poke deep holes evenly across the cake.
Mix the pudding. Whisk the pudding mix, milk, nutmeg, cinnamon, vanilla extract, and rum extract if using until slightly thickened but still pourable.
Fill the cake. Slowly pour the pudding mixture over the warm cake, spreading it so it sinks into the holes. Refrigerate for at least 1 hour.
Top and chill. Spread the whipped topping evenly over the cake and dust lightly with nutmeg. Refrigerate for 2 to 3 hours if time allows.
Notes
Warm cake. Pouring the pudding over a warm cake helps it sink deeper for a creamier texture.
Pudding texture. The mixture should be slightly thickened but pourable so it fills the holes properly.
Chilling. One hour is the minimum, but longer chilling improves flavor and structure.
Make ahead. This dessert sets beautifully overnight and is ideal for holiday prep.
