Preheat the oven to 350℉. Prep 3 - 9” cake pans with cooking spray containing flour or line with parchment paper. Set them aside.
Whisk together the dry ingredients: all-purpose flour, baking powder, baking soda, cinnamon, nutmeg, allspice, cardamom, ginger, cloves, and salt in a small bowl. Set aside.
In a large bowl, combine the wet ingredients: beat the butter, sugar, and brown sugar until light and fluffy.
Add in the eggs, one at a time, and beat until incorporated.
Add in the molasses and vanilla.
Begin and end with flour while alternating the flour mixture and the buttermilk.
Pour batter equally between all three prepared pans.
Bake for 20-22 minutes or until a toothpick stuck in the center of the cake comes out clean.
Let the cake rest in the pans for 10 minutes before inverting and releasing them.
Allow the cakes to cool completely on a wire rack.
How to Make Eggnog Buttercream Frosting
In a large bowl, beat the room temperature butter for 1-2 minutes until it becomes light in color.
Add the powdered sugar and beat until smooth. Next, incorporate the eggnog, vanilla, nutmeg, and cinnamon, ensuring the mixture is smooth and creamy.
Sugared Cranberries
Combine ½ cup of water in a large skillet with ½ cup of white sugar.
Dissolve the sugar over medium-low heat, add the cranberries, and toss them with the sugar mixture.
Remove the cranberries from the saucepan using a slotted spoon and place in the refrigerator for at least 1 hour.
Place the 1 cup of granulated sugar in a large bowl and add the cranberries a bit at a time.
Toss in the granulated sugar and allow the cranberries to dry completely before adding them to the top of the cake.
Assemble the Layer Cake
Place the bottom layer on a cake stand with the flat side facing up to assemble the cake.
Scoop about ½ cup to ¾ cup of frosting and spread it evenly over the cake.
Repeat the same thing with the second layer. For the last layer, place it with the top side facing up.
Spread a thin layer of frosting on top and around the edges of the cake using an offset spatula.
Scrape the majority of the frosting off to create a barely frosted cake. Smooth the top layer.
Decorate the top as desired with sugared cranberries, rosemary, anise, and cinnamon sticks.
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Remove the cake about 30 minutes before serving.
