Ingredients

Fluffy White Cake

  • 2 cups all-purpose flour
  • 1 ½ cups granulated sugar
  • 3 ¼ teaspoon baking powder
  • 1 teaspoon salt
  • 10 tablespoon unsalted butter diced and at room temperature
  • ¾ cup + 1 tbsp whole milk
  • 2 teaspoon vanilla bean paste or pure extract
  • 5 large egg whites

Cranberry Filling

  • 6 oz fresh or frozen cranberries
  • ¾ cup granulated sugar
  • 3 tablespoon orange or cranberry juice
  • 1 teaspoon vanilla bean paste
  • ½ teaspoon cinnamon
  • 1 pinch cloves

Spiced Buttercream Frosting

  • 1 ½ cups unsalted butter softened
  • 4 to 6 cups confectioners' sugar
  • 2 to 4 tablespoon milk
  • 2 teaspoon vanilla bean paste or extract
  • ½ teaspoon ground cinnamon
  • ½ teaspoon ground cardamom
  • teaspoon ground gloves

Instructions

Fluffy White Cake

  • Preheat the oven to 350°F. Grease, flour, and line the bottoms of three 6-inch cake pans with parchment paper. Set aside.
  • In the bowl of a stand mixer fitted with paddle attachment, add the flour, sugar, baking powder, and salt. Mix on low speed just to combine. Add the butter and mix on medium speed until the mixture becomes crumbly and the butter pieces are coated in flour. 
  • Add the vanilla to the milk. Pour in about half of the milk mixture into the butter mixture. Mix on medium speed until evenly moistened. The batter will still be quite lumpy.
  • Mix the remaining milk with the egg whites. With the mixer on low speed, slowly stream in about ⅓ of the egg mixture at a time. Mix until the egg mixture is completely incorporated then stop the mixer and scrape down the sides of the bowl. Repeat this two more times using the remaining egg mixture. If there are still some lumps in the batter at the end, that is okay. Do not over mix.
  • Evenly distribute the batter among the prepared pans. Bake for 24 to 27 minutes or until a toothpick inserted in the center of the cakes comes out clean. Allow the cakes to cool on a wire rack for 10 to 20 minutes before removing them from the pans. Let the cakes completely cook before filling and frosting.

Cranberry Filling

  • Place the cranberries, sugar, and juice in a saucepan over medium heat. Cook the cranberries until the liquids start to release from the fruit and come to a simmer. Lower the heat to low and simmer for about 10 minutes. 
  • Remove from the heat and blender the mixture with an immersion blender. The cranberry filling won’t be very smooth, but that is okay.
  • Return the cranberry filing to the stove and stir in the vanilla, cinnamon, and cloves. Simmer for another 3 to 4 minutes to thicken. 
  • Scrape the mixture into a heat-safe container, cover, and refrigerate until cool and thick.

Spiced Buttercream Frosting

  • Using a stand (or hand) mixer fitted with the paddle attachment, beat butter on medium-low speed until smooth and creamy (1 to 3 minutes).
  • Stop the mixer and add 4 cups of confectioners' sugar. Mix in the sugar on low speed until just combined. Add 2 tablespoons of milk, vanilla, and spices and mix until blended.
  • Turn the mixer up to medium-high speed and mix for 3 to 5 minutes, until the buttercream is light, airy, and nearly white. If needed, add the additional confectioners’ sugar or milk until desired consistency is achieved. The buttercream should spread smoothly without tearing the crumb of the cake but thick enough that it holds shape when piped and spread between the layers.
  • Reduce the mixer speed to low and mix for about a minute or two to smooth out the air bubbles.

Assembly

  • Fill a piping bag fitted with a 1M star piping tip with buttercream and set aside.
  • Place one layer of cake on a cake board or serving plate. Spread on ¼ cup of buttercream with an offset spatula until smooth. It will be a rather thin layer of buttercream. Pipe a ring of buttercream around the outer edge of the cake to create a frosting dam. Fill the dam with about ⅓ cup cranberry filling and spread it out with the back of a spoon. 
  • Place the next layer of cake on top and repeat. Place the final layer of cake on top and crumb coat the cake in a thin layer of buttercream. Chill the cake in the refrigerator for 15 minutes. 
  • Reserve 1 to 1 ¼ cups of buttercream for decorating. Smoothly frost the cake with the remaining buttercream, leaving the top edge unfinished.

To Decorate

  • Reserve about ½ cup of the buttercream and tint the remaining portion green. Fit a #4B piping tip in the bottom of a piping bag. Using a small offset spatula, stripe the inside of the piping bag with some of the plain buttercream. “Paint” the inside of the piping by swiping up the sides of the bag in a few different spots. Fill the piping bag with the green buttercream.
  • Use the edge of an icing smoother or offset spatula to lightly mark a triangle shape on the side of the cake. Starting at the bottom of the cake, pipe shell patterns with the 4B piping tip to fit the triangle shape, one row at a time. Allow the rows to slightly overlap and the shells on the sides to fan out as you work your way up to the top point of the tree. Be sure to release the pressure on the piping bag between shells to create clean tails.
  • Fill a piping bag fitted with the #3 piping tip with plain buttercream. Pipe swags down the length of the tree. Place gold and red sugar pearls on the tree to resemble lights and ornaments.
  • Switch the piping tip to a #129 and pipe snowflakes around the sides of the cake as desired.
  • For the top of the cake, spoon a mixture of your favorite gold holiday sprinkles around the edge. Enjoy!
