Pink Champagne Cake
A special cake for any celebration. Pink champagne adds a light flavor to the cake and the buttercream for a very delicate party cake. Strawberries and white chocolate complement the delicate champagne flavor to make the cake shine. Pink champagne cake was popular in California during the 1960’s. Best eaten the day the day it is made and assembled, but will last for a couple of days unrefrigerated. This cake recipe is from American Cake by Anne Byrn. The buttercream and strawberry puree recipes are slightly adapted from The Cake Bible by Rose Levy Beranbaum. The amount of buttercream in my recipe will cover an 8 inch 6-layer cake, which is one and a half of the original recipe. Listed in the notes section, are the ingredient amounts if you want to make a 3-layer cake. Three recipes make up this cake and the prep and cook times are listed in the instructions for each recipe. Give yourself plenty of time. All three recipes can be made in advance.

  • 1 ½ cups / 332g granulated sugar divided
  • cup / 75 ml water
  • 7 large egg whites room temperature
  • ¾ tsp + ⅛ tsp cream of tartar

  • Finely grated zest from one lemon
  • Pink food coloring*
  • ½ cup / 125 ml strawberry purée
  • Decorate with shaved white chocolate or sliced strawberries, or grated coconut, or edible rose petals, or other candy garnishes
Strawberry Purée -Takes about 20 - 30 minutes to make, not including the defrosting time.
  1. Start defrosting the strawberries the day before or first thing in the morning. They will take several hours for the strawberries to defrost and release their juice. Suspend a colander over a large mixing bowl. Add the frozen strawberries to the colander and let the strawberries thaw out and release their own juices. Occasionally press down on the strawberries to encourage the juices to release. You should get close to 1 1/4 cup juice.
  2. In a small saucepan, pour in the strawberry juice and turn the heat to medium high. Reduce the juice to about 1/4 cup.
  3. Purée the strawberry pulp in a food processor until smooth. There will be some texture because of the seeds, but you want it as smooth as you can.
  4. When the strawberry juice is reduced add the strawberry puree and stir. Add the lemon juice and taste the strawberries. Depending on how tart or sweet the strawberries taste, add about 2 -3 teaspoons of granulated sugar. You will not want it very sweet because the buttercream will be sweet. Stir until the sugar is dissolved. Pour the strawberry purée into a heat proof glass measuring cup. You should have about 1 ¼ cup. The purée can be stored in an airtight container for 10 days in the refrigerator, or frozen for up to one year.
Cake - Takes about 20 minutes to mix, about 25 minutes to bake, 40 minutes - 1 hour to cool
  1. Place the oven rack in the middle of the oven and preheat to 350˚F/ 175˚C / Gas Mark 4
  2. Prepare 3, 8-inch cake pans. Cut a circle of parchment paper for each pan, large enough to fit inside your cake tins. Lightly butter the bottom and sides of each pan, then coat with a light dusting of cake flour around the sides and bottom. Tap the pan against the counter to release any excess flour. Discard the excess flour. Place the parchment paper circles inside each cake tin. Set aside.
  3. Place the flour, baking powder, and Kosher salt inside a medium size bowl. Mix the flour mixture with a wire whisk to get all the ingredients thoroughly mixed together. Set aside.
  4. Place the egg whites, champagne, vanilla and oil in a medium mixing bowl and whisk together until thoroughly mixed through. Set aside.
  5. Put granulated sugar and butter in a bowl of a stand mixer, or large bowl if using a handheld mixer. Mix on medium speed until lighter and fluffy, about 3-4 minutes.
  6. Scrape down the sides of the mixing bowl with a rubber spatula.
  7. Turn the speed on low and add a portion of the flour to the butter, and mix. Then add a portion of the egg whites to the bowl and mix. With the beater on, alternate adding the flour and the egg whites to the butter, ending with the flour.
  8. Turn off the mixer and stir in one tiny drop of pink food coloring. Stir by hand until all mixed through.
  9. Divide the batter evenly between the three prepared cake pans.
  10. Place all three pans in the oven on the center rack and bake until the cake is lightly golden brown, the cake has pulled away from the sides of the pans, and a cake tester comes out clean when poked in the center of each cake. About 23-27 minutes. Be careful not to overbake the cakes. The cakes will taste dry if they are overbaked.
  11. Place the cakes in the pan on cooling racks and cool for 10 minutes. After the cakes have cooled for 10 minutes, run a knife around the edge of each cake pan to loosen the cakes. Turn the cake upside down resting the top of the cake in one hand, and pull the pan away. Carefully peel off the parchment paper and place the cake right side up on the cooling rack. Repeat for the remaining cakes. Cool completely before frosting. Can be made in advance. Wrap each cake tightly with plastic wrap and store on the counter for 1 day.
Pink Champagne Buttercream- Takes about 20 to 30 minutes to make.
  1. In a large mixing bowl beat the butter with a hand-held mixer until smooth. Set aside away from any heat source.
  2. Place a heatproof glass measuring cup to the side next to the stove where you will be working. In a small heavy saucepan heat 1 cup plus 3 Tbs sugar and 3/8 of a cup (90 ml) of water over medium high heat. Stir the sugar in the water until it is completely dissolved and the liquid is bubbly. Reduce the heat to the lowest setting. (If using an electric range turn off the heat and set the saucepan aside).
  3. In a large mixing bowl of a stand mixer, beat the egg whites until foamy. Add the cream of tartar and beat until the egg whites form soft peaks. Add the remaining sugar, one tablespoon at a time to the egg whites, and beat on high speed until stiff peaks form. Turn off the mixer and return your attention back to the sugar syrup.
  4. Turn the heat up to high and boil the sugar syrup until it reaches the temperature of 248˚F - 250˚F (120˚C) using a candy thermometer or an instant read thermometer. Pour the syrup into the heatproof glass measuring cup to stop the cooking.
  5. Return to the egg whites and turn the speed up to high speed. If using a handheld mixer, slowly drizzle the syrup into the egg whites without the syrup touching the beaters. If you are using a stand mixer, turn the speed off, add a little of the syrup, then turn the speed up to high and beat for 5 seconds and stop. Repeat the process until the syrup is added into the egg whites, scraping the clinging syrup with a rubber spatula to get every drop. If you get the syrup on the whisk or beaters, the syrup will just spray over the sides of the bowl and not mix into the egg whites. Once all the syrup is added, turn the speed down to medium and beat for a couple of minutes to cool the whipped egg whites.
  6. On low speed, beat in the whipped butter into the cool egg whites, one tablespoon at a time. The buttercream will look thin at first, but it will eventually thicken up. If at any time the buttercream starts to look curdled, stop adding butter and turn the speed up a little. Beat until smooth. Once smooth, continue to add the butter one tablespoon at a time until done.
  7. Lower the speed and add in the pink champagne and lemon zest, and beat in. Add one tiny drop of pink food coloring and mix until thoroughly mixed through. (Can be made in advance up to this point, keep in the refrigerator for 2 days or freeze).
  8. Measure in a dry measuring cup, 2 ¾ cup (685 ml) buttercream and place in a medium mixing bowl. Set the remaining buttercream aside. Add ½ cup (125ml) cooled strawberry purée to the buttercream and beat by hand until mixed together. Cover both bowls of buttercream and keep on the counter away from any heat until you are ready to assemble the cake.
Putting it all together- About 30 minutes to assemble.
  1. For a 6-layer cake, measure with a ruler the height of each cake and mark the center with a toothpick. Measure and mark the center point around the circumference of each cake. The toothpicks are your guide to cut each cake in half through the middle. With a long serrated knife, rest the serrated edge up against the side of a cake and on top of the toothpicks. With a gently sawing motion cut through the cake, paying attention to your markers and turning the cake as you work your way around the circumference, and then through the middle of the cake. Repeat for each cake. Keep the pairs together. Select which cake layer is going to be your top layer and set aside.
  2. Take apart one divided cake and place the bottom portion of the cake on your cake plate.
  3. Spread ½ cup (125ml) of the strawberry buttercream over the top of the cake. Make a smooth and level layer of buttercream. Place the top portion of the cake on top of your frosted layer and spread ½ cup (125 ml) of strawberry buttercream evenly and smoothly across the top.
  4. Continue to stack and frost the tops of each layer with ½ cup (125ml) strawberry buttercream until you get to the top layer. The strawberry buttercream is to be used only for the middle layers of frosting. While you are stacking your cake layers, try to get them as level as possible. Trim off the top of each layer if they are uneven, before you frost the layers.
  5. For a three layer cake frost each layer with 3/4 cup pink champagne buttercream or strawberry pink champagne buttercream.
  6. Once the layers are assembled, spread a thin "crumb" layer of pink champagne buttercream around the top and sides of the cake. This is to get the cake frosted with a thin protective layer so the crumbs won't show through the frosting. Once done, spread more buttercream all over the top and working down the sides of the cake for a nice finishing layer of buttercream. Frost as much as wanted or needed.
  7. Decorate the cake with shaved white chocolate over the top of the cake and extra strawberries for decoration.
  8. Keep the cake in a cool spot loosely covered with aluminum foil up to 2 days unrefrigerated. Best if eaten the day it is assembled.
Recipe Notes

Cake flour has less gluten and produces a more delicate cake than with all-purpose flour. If you like to bake cakes, cake flour is nice to have around. Swans Down and Softasilk are two brands that sell cake flour. Do not buy self-rising cake flour. If you do not want to buy cake flour, or cannot get some, substitute 1 cup of all-purpose flour, plus 2 Tbs all-purpose flour, plus 2 Tbs cornstarch for every cup of cake flour.
