This festive holiday cake really makes a statement with its height and glittering meringue decorations. The cake layers are assembled in a somewhat unconventional way, using a piece of poster board formed into a cone shape. There are several steps to this cake, but it’s not difficult to make. It may look stately with its towering height, but it requires only four 6-inch round cake layers to achieve. Use your favorite raspberry jam as filling. Be sure to refrigerate the cake well to set the buttercream. This cake should be cut slightly chilled. Slices can also be served chilled, or at room temperature.

Instructions
Cake layers
Preheat oven to 350°F. Grease and flour four 6x2-inch round cake pans.
Whisk together the first 4 ingredients in a large mixing bowl. In a four-cup measure, stir together the sour cream, water, eggs and extracts. With a hand mixer running on low speed, gradually pour the liquid ingredients into the dry ingredients. Scrape the bowl down and mix again.
Divide the cake evenly between the pans. Bake for 25- 35 minutes, or until the cake springs back in the center when pressed.
Turn out the cakes on a wire rack to cool completely.
Using a serrated knife or leveler, torte each cake horizontally so that you have eight 6-inch cake layers.
Next, trim two of the layers to 5-inches, another two to four inches, and another two to 3-inches. Leave one set of 6-inch cake layers as-is (untrimmed). Save all the cake scraps in a bowl and cover with plastic wrap; reserve for later use.
Chill the cake layers in the refrigerator to firm them, about 30 minutes. Meanwhile, make the Swiss meringue buttercream.
Swiss meringue buttercream
Place a saucepan filled 1/3 full of water over medium heat. Bring to a simmer.
In a large stainless-steel bowl, combine the egg whites and sugar. Set the bowl over the simmering water and cook while whisking intermittently. Cook until the mixture is hot (110°F) and you can no longer feel sugar granules when the mixture is rubbed between your finger and thumb. Transfer the hot mixture to the bowl of a stand mixer fitted with the whisk attachment. Beat on high speed for 10 minutes or until a thick, shiny meringue forms that holds stiff peaks. The bowl should feel cool to the touch. If it doesn’t, refrigerate the meringue in the bowl for 10 minutes. Return the bowl to the mixer and swap the whisk attachment for the paddle attachment.
Beat the room temperature butter into the meringue one cube at a time on medium-low speed, waiting to add the next cube when the previous cube disappears. The batter will deflate with the butter addition, and may even look curdled (if the butter was the slightest bit cold this happens), but this is normal. When all of the butter is added, beat the mixture on high speed until light in color and fluffy, about 5 minutes. Beat in the almond extract and salt. To whiten the frosting, add just a tiny dab of royal purple gel food color to the buttercream and mix to combine. This will color correct some of the natural butter yellow tinge of the finished buttercream.
Transfer the buttercream to two large disposable piping bags with a 1” hole snipped in the tips.
Assemble the cake
Crumble the reserved cake scraps in the bowl and remove any hard or crust bits. Add Swiss meringue buttercream 1 tablespoon at time, mixing well to form a cake pop mixture that holds together and packs well. Completely fill the sugar cone with the cake pop mixture, and cover the remaining mixture for later use.
Make a tall cone shape using the poster board and secure the outside seams with packing tape. Trim it to 16” tall. The bottom opening should be about 6.5 inches in diameter. If your opening is larger or smaller, remove the tape and twist the cone so the bottom opening is 6.5-7 inches in diameter. Close all seams on the outside of the cone with packing tape, and do the same on the inside. The interior also needs to be perfectly smooth for a flawless cone shape
Make room in your refrigerator for a 16” tall cake.
Use a tall stock pot in which to place the cone upside-down, and pad the bottom of sides of the pot with tea towels or crumpled aluminum foil. The cone should be firmly standing upright with the open end toward the sky.
Pipe about 4” of buttercream into the tip of the cone. Press the filled sugar cone into the buttercream until the frosting squeezes around the sugar cone. Pipe in a little more buttercream to cover the sugar cone. Pack the remaining cake pop mixture into the cone firmly. Pipe in a thin layer of buttercream to cover it. Place a 3” cake layer on top of the piped frosting. Pipe a ring of buttercream around the edge of the cake layer and fill with a thin layer of raspberry jam. Top with a second 3”inch cake layer pipe another ring of buttercream around that cake layer and fill with raspberry jam as before.
Continue this process with the 4” cakes, 5” cakes, and 6” cakes. The cake layers should come to the top of the open end of the cone, or within 1-2” of the opening (it doesn’t need to be exactly 16” tall). If the cake has to travel, dowel the cake ¾ of the way through the center of the cake to secure all the layers together.
Transfer the upside-down cone in the pot to the refrigerator and chill for 1 hour. Remove the cone from the pot and turn upright onto a serving plate. Refrigerate the unmolded, upright cake for another hour.
Carefully unmold the cake by cutting the tape seams on the outside with an x-acto knife or sharp scissors. As you unfurl the poster board cone, snip the inside tape seams as the appear. Gently remove the unfurled poster board from the cake. Transfer the cake to the refrigerator while you make the meringues.
Meringue cookies
Preheat the oven to 170°F. Line two or more large cookie sheets with parchment paper. Fit two or more large pastry bags with a large closed star decorator piping tip.
Place the egg whites in a spotlessly clean bowl and whip them with an electric mixer on medium speed until frothy. Add the cream of tartar. Start the mixer again and continue to beat the egg whites.
Once the egg whites form soft peaks increase the speed to high and gradually add the sugar, a little at a time. Beat the egg whites until they are very shiny and hold stiff peaks but are not dry or crumbly, about 6 minutes. To make sure the sugar has completely dissolved, rub a bit of the meringue between two fingers to see if any granules of sugar remain. If grains are present, continue to beat the meringue until the sugar has fully dissolved.
Spoon the meringue into the prepared piping bags. Pipe meringues of large and small sizes onto the lined cookie sheets. Sprinkle meringues with the silver dragees before baking.
Bake for 90 minutes, turning them halfway through the cooking time to ensure even cooking. When the meringues are done, they should be dry to the touch. You can remove them from the oven, or if time permits, turn off the oven and let them stand inside the oven until the oven cools completely. When cool, you should be able to lift the cookies easily from the parchment sheet.
Decorate the cake
Apply a thin coat of the leftover Swiss meringue buttercream all over the chilled cake. Starting at the bottom of the cone, apply the meringue cookies, using the larger ones first, around the circumference of the cone.
Work your way up, using buttercream as needed as adhesive to the backs of the meringues, and fill in gaps using smaller meringues. It’s okay if not every space is filled, and you can still see some of the smooth white buttercream between the meringues.
Store the decorated cake in the refrigerator until ready to serve.
To serve the cake, cut the top 1/3 of the cake away, just below the cake pop layer, and place it on a plate to the side (you may ask guests if anyone wants the sugar cone tip!). Slice the remaining layer cake into thin, tall pieces. You may divide one tall piece into two at a buttercream layer.
Garnish cake slices with pomegranate arils, if desired.
Notes
Winter is the perfect time to make meringue cookie because of the dry atmosphere. Avoid making meringues in humid weather.
I used a tiny drop of royal purple gel food color to cancel the slight yellow tinge in the buttercream. If you do this, only use a tiny drop, and remember that food color intensifies over time. If used correctly, the addition of purple makes a wintry (or wedding) white buttercream that matches the meringue cookies.
