This past year has treated me pretty well, so I decided to have a birthday celebration that my sister described as "extra." Printed invitations, wine, charcuterie, and this beautiful cake with pink champagne icing. You can tell I went all out because I splurged on a bottle of Pannier Brut Rose Champagne, which might have had something to do with the fact that the label matched my pink and gold theme. Gold edible confetti, glitter cake picks, and a table scattered with pink and gold confetti completed the look. Champagne is inherently celebratory, so you could also make this cake for a wedding shower, graduation, or anytime you would like to pop open a bottle.
The Science.
Even with all of the glittery decorations, the champagne icing is what really makes this cake stand out. I had great success blending liquor into meringue icing for my Elderflower Cupcakes a while back, but this time I wanted an icing that was more sturdy for decorating. With this in mind, I decided to make a Swiss meringue buttercream. By adding the champagne to the cooked meringue first, the bite of the alcohol evaporated off, leaving the light fruity taste of the pink champagne. Cooking off the moisture in this step also helps the butter incorporate into the meringue at the end.
The Recipe.
For the cake, follow the white cake instructions from my Orange Creme Cake, except pour the batter into three 6 x 3 inch round pans coated with baking spray and lined with parchment paper. If you would like a pink ombre effect, you can divide the batter into bowls and add pink food color before pouring into the pans. After baking, invert cakes onto a wire rack to cool completely. If you would like to make cupcakes as well, make a double batch of batter and pour the rest into lined cupcake tins and bake cupcakes for approximately 17 minutes.
Pink Champagne Swiss Meringue Buttercream:
4 large egg whites, at room temperature
1 cup sugar
1/2 cup rose champagne or sparkling wine
1 pound (4 sticks) butter, at room temperature
1/4 teaspoon sea salt
pink food color
Bring 1 inch of water to a simmer in a small saucepan. Place the egg whites, sugar, and champagne in a medium metal bowl, then place the bowl over the simmering saucepan to make a double boiler. Make sure the bottom of the bowl is not touching the water, we only want the steam to cook the egg whites gently as they whip. Using a hand mixer, beat the mixture on high speed for 5 minutes, until stiff peaks form. Remove from heat, and continue to whip until the meringue is cool, about 2 minutes. Gradually add the butter while beating on high, 2 tablespoons at a time. Add the sea salt and food color and beat until completely incorporated and the icing is smooth.
Assembling the cake:
Level off any crown on your cake layers with a serrated knife. This will ensure that you have a beautiful, even cake in the end. Place the bottom cake layer on a rotating cake stand (or a flat plate or stand you can turn with one hand). Spread with icing, then place the next cake layer, and repeat. Once you have all three cake layers, cover the entire cake with a thin crumb coat of icing. Using an offset spatula or long knife, spread another layer of icing onto the cake. In order to get perfectly smooth icing, I used this icing smoother while slowly rotating the stand.
To decorate, I pressed Wilton Gold Edible Heart Accents onto the cake, in a gradient going up the sides to mimic champagne bubbles. I then placed the cake on a gold cake board and decorated with gold glitter cake picks. For the cupcakes, I piped a swirl of icing with a 1M tip and sprinkled with the gold hearts. To complete the display, I scattered gold and pink confetti on the table and displayed the beautiful champagne bottle alongside. The cake can be stored in an air-tight container in the refrigerator for up to one week. However, water condensation might make the edible confetti disintegrate into the icing so it's best if the confetti is added shortly before serving.
