Creating this incredible Eggnog Cake is an enjoyable process. Follow these simple steps for success:

1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, nutmeg, cinnamon, and salt.

3. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy.

4. Add Eggs and Eggnog: Incorporate the eggs one at a time, mixing well after each addition. Then, add the eggnog and vanilla extract, combining thoroughly.

5. Combine Mixtures: Gradually fold in the dry mixture into the wet ingredients until just combined. Avoid over-mixing.

6. Divide the Batter: Pour the batter evenly into the prepared cake pans.

7. Bake: Place the pans in the preheated oven and bake for 25-30 minutes. A toothpick inserted into the center should come out clean when done.

8. Cool the Cakes: Once baked, remove the cakes from the oven and allow them to cool in the pans for about 15 minutes. After that, transfer them to wire racks to cool completely.

9. Prepare Frosting: In a bowl, mix the powdered sugar with the milk or cream to achieve a spreadable consistency. Adjust milk or sugar as necessary.

10. Assemble the Cake: Once completely cooled, place one cake layer on a serving platter. Spread a layer of frosting on top, then add the second layer. Finish by frosting the top and sides of the cake.

11. Garnish: If desired, sprinkle a touch of nutmeg or cinnamon on top of the frosted cake for added visual appeal.

Now your Eggnog Cake is ready to be enjoyed, and every step contributes to the wonderful end result.
