A warmly spiced holiday cake with cinnamon, nutmeg, and ginger, topped with a creamy, festive eggnog buttercream — perfect for Christmas celebrations.
For the Cake:
2½ cups all-purpose flour
1½ cups brown sugar, packed
½ cup granulated sugar
4 large eggs
½ cup vegetable oil
1 cup buttermilk
2 tsp vanilla extract
2 tsp baking powder
1 tsp baking soda
½ tsp salt
2 tsp ground cinnamon
1 tsp ground ginger
¾ tsp ground nutmeg
½ tsp ground cloves
For the Eggnog Buttercream:
1 cup unsalted butter, softened
4 cups powdered sugar, sifted
4–5 tbsp eggnog
¼ tsp ground nutmeg
1 tsp vanilla extract
(Optional: ½ tsp rum extract)
Preheat oven to 350°F. Grease and flour two 9-inch cake pans.
In a bowl, whisk flour, baking powder, soda, salt, and spices.
In another bowl, beat sugars and oil. Add eggs one at a time, then stir in vanilla.
Alternate adding dry ingredients and buttermilk to the wet mixture. Mix just until combined.
Divide batter evenly and bake 28–32 minutes. Cool completely.
For buttercream: beat butter until creamy. Gradually add powdered sugar. Add eggnog, vanilla, nutmeg, and optional rum extract. Beat until fluffy.
Frost cooled cake layers and garnish as desired.
Make ahead: store layers unfrosted for 1 day or freeze for longer.
For cupcakes, bake 18–20 minutes.
Store frosted cake in fridge for up to 5 days.
