Festive eggnog cake is the perfect dessert to serve this holiday season! Make this moist eggnog-flavored cake bursting with delicious seasonal spices and layered with creamy eggnog buttercream!
Preheat the oven to 350 degrees Fahrenheit. Grease 2 8-inch round cake pans and set aside.
In a large mixing bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, salt, nutmeg, and cinnamon.
Add the eggnog, vanilla, and oil to the dry ingredients and beat with the paddle attachment of a stand mixer or a hand mixer just until fully combined.
In a separate bowl, whip the egg whites until medium-stiff peaks form. Fold into the batter until no streaks of egg whites remain.
Separate the batter evenly into the two cake pans and bake for 35-40 minutes, or until the center of the cake springs back when pressed on.
Allow the cake layers to cool completely before frosting. For easier frosting, wrap the cooled cake layers in plastic wrap and freeze for 4 hours or chill in the fridge overnight before assembling.
Eggnog Buttercream
Add the butter to the bowl of a stand mixer fitted with the paddle attachment. Alternatively, you can use a large mixing bowl and use a hand mixer to beat the butter until smooth and creamy.
Add the powdered sugar, vanilla extract, rum extract, and salt. Mix until combined.
Use immediately to frost the cooled cake layers for best results.
