Overnight Eggnog Coffee Cake makes a delicious holiday breakfast. The whole thing can be prepped the night before and then popped in the oven Christmas morning.
After about 33 minutes of baking, you have a warm coffee cake flavored with eggnog, cinnamon, and nutmeg. Drizzle with an easy eggnog glaze for a little extra sweetness.
Prep The Night Before
No one wants to spend a holiday morning in the kitchen. This coffee cake can be completely prepped and placed in a baking pan the night before. You’ll start by combining the streusel ingredients and then mixing together the batter. Transfer the batter to a greased 9×13-inch pan and then sprinkle the steusel on top. Cover with plastic wrap and refrigerate overnight.
Note: You can bake it right away if you wish. Decrease the baking time slightly.
2-Ingredient Glaze
After baking, to finish off the coffee cake, drizzle it with an easy 2-ingredient glaze. Place 1 cup of powdered sugar in a small bowl and whisk in 2 to 3 tablespoons of eggnog. You want it thin enough that it’s easy to drizzle, but thick enough that it doesn’t totally sink into the coffee cake.
Lots Of Eggnog Flavor
One cup of eggnog in the batter gives this coffee cake lots of eggnog flavor. Plus there’s 1 teaspoon of rum extract to enhance the eggnog’s flavor. Cinnamon and nutmeg in the streusel nicely complement the flavor of the eggnog. If you don’t have rum extract, you can use vanilla extract instead.
