Just in time for New Year’s Eve, I’m sharing a fabulous high altitude champagne cake with champagne buttercream. The cake is the lightest, softest cake you could imagine, and the silky buttercream is flavored with a champagne reduction that adds the most delicious flavor and a lovely ivory color. To decorate the cake, I scattered the buttercream with gold and white sugar pearls and coarse sparkling sugar. Delicate, shimmering fondant snowflakes add the perfect touch for a New Year’s Eve cake.
I’ve also included an option to make this recipe into a delicious mimosa cake, so be sure to scroll through the post for instructions!

Why is champagne so good in cake?
Champagne cake is a vanilla cake that is made with champagne, which replaces the usual milk or buttermilk in a vanilla cake recipe. The fizzyness of the champagne lightens the cake batter, making an incredibly soft, tender, light and fluffy cake with a delicate champagne flavor.
You can pair a champagne cake with any complementary flavor of filling or buttercream. Strawberry buttercream or raspberry buttercream would both be fantastic. But a champagne buttercream adds even more champagne flavor to this special occasion cake.
See the recipe card at the end of the post for the full ingredients list and instructions.
Ingredients
- Cake Flour. Cake flour, rather than all-purpose flour, makes a very soft, tender crumb that’s just irresistible.
- Granulated Sugar. Adds sweetness and moisture.
- Baking Powder. Leavens the cake, making it rise.
- Coarse Kosher Salt. Balances the sweetness.
- Champagne. Adds moisture, flavor and sweetness. The bubbles contribute to the light and airy texture of the cake.
- Vegetable Oil. Adds moisture and keeps the cake soft and fluffy.
- Eggs. Structure and richness.
- Vanilla Extract. Flavor.
TIP: The cakes are very soft, and parchment paper on the bottoms of the pans ensures they won’t stick to the pans when you turn them out.
Instructions
This cake is so easy to make! Just sift the dry ingredients together, whisk in the liquid ingredients, and the cake batter is ready to bake.
- Preheat the oven to 350, and grease three 8-inch cake pans with non-stick spray. Line the bottoms of the pans with a circle of parchment paper, and spray the paper as well.
- In a large bowl, sift together the flour, sugar, baking powder and salt. Sifting the dry ingredients is important for removing any lumps and ensuring a light and fluffy cake.
- Add the champagne, oil, eggs and vanilla, and whisk for about 30-40 seconds until smooth and well combined.
- Divide the batter between the pans. Bake on the center oven rack until a cake tester or toothpick comes out clean, about 22-25 minutes.
- Set the pans on a wire cooling rack, cover loosely with a clean kitchen towel, and cool completely before frosting.
TIP: You should open your bottle of champagne right before adding it to the cake batter for maximum fizzyness.
Making the Buttercream
Make a champagne reduction.
- To get the most champagne flavor into your buttercream without adding excessive liquid, you’ll need to make a champagne reduction. This simply means that you’ll be boiling the champagne down to let the water evaporate, leaving behind a concentrated champagne syrup.
- To make a champagne reduction, pour the champagne into a saucepan and set over medium heat. Simmer until the champagne is reduced to about 1/3 cup.
TIP: Cool the champagne reduction completely to room temperature before adding it to your buttercream.
Add to buttercream.
- In the bowl of your stand mixer fitted with the whisk attachment, beat the butter for one minute.
- With the mixer on low, gradually add the powdered sugar, the meringue powder, salt and vanilla; the mixture will be clumpy. Add the cooled champagne reduction.
- Increase the speed to medium, and whip for 4-5 minutes, scraping the bowl several times, until very light and fluffy.
- Stack, fill and frost the cooled cakes with the buttercream.
How to Make a Mimosa Cake
A mimosa is a delicious drink, often served with breakfast, made with champagne and orange juice. With a few simple adjustments, you can turn this champagne cake into a mimosa cake!
Cake
- Instead of 1 1/2 cups champagne, add 1 cup of champagne + 1/2 cup orange juice.
- Add 1 teaspoon freshly grated orange zest + 1 1/2 teaspoons orange extract.
Buttercream
- Add 1 teaspoon orange extract.
- For the look pictured here, fill and frost the cake with the buttercream. Tint about a half cup of buttercream with a drop of orange gel food coloring + a drop of yellow food coloring. Swirl the orange buttercream around the cake, but leave the top white.

Frequently Asked Questions
There’s no need to buy an expensive bottle of champagne for your champagne cake, unless you really want to splurge. I’ve made champagne cakes with both Korbel and Martini & Rossi brands, which are pretty affordable and add wonderful flavor to the cake. A sweet champagne, rather than dry, adds the best flavor.
No. The alcohol in the champagne in both the cake and the buttercream is completely cooked off, leaving behind just the flavor.
It tastes like champagne, but if you’re not familiar with the flavor, you’ll notice sweet vanilla flavor notes with a pleasant tartness from the champagne.
If you want to make this cake without champagne, try substituting another sweet, fizzy, bubbly liquid, such as Sprite, Ginger Ale, or a non-alcoholic sparkling beverage.
If you’re not able to find cake flour in your local grocery store, you can purchase it online. I usually use Swans Down cake flour for my white cakes and vanilla cakes, but Softasilk works just as well, too. In a pinch, you can make a cake flour substitute with all-purpose flour and corn starch. Measure 1 cup of flour into a bowl, then remove 2 tablespoons. Add 2 tablespoons of corn starch to the flour and whisk together until well combined.
If you want to fill or frost your cake with something other than the champagne buttercream, fruit flavors would complement the champagne cake the best. Keep in mind that other flavors might overpower the flavor of the champagne in the cake, though. Strawberry, raspberry, and even lemon would all be wonderful.
This cake is so soft and moist, it will stay fresh tasting for days after baking. Leftover cake should be stored in an airtight container or cake carrier at room temperature for up to 5 days.
The delicate snowflakes make the most gorgeous decoration on this snowflake cake, making it perfect for a Christmas cake or New Year’s Eve cake. I made the snowflakes out of white fondant, and used these plunger style snowflake cutters to cut the snowflakes. After they dried and hardened, I brushed them with edible silver luster dust.
1. Roll out the fondant to about about 1/8 inch thick, using powdered sugar or corn starch to keep it from sticking.
2. Use the snowflake cutters to cut the snowflakes, then use the spring-loaded plunger to push them out onto a flat surface (like a cutting board) that’s lined with wax paper or parchment paper.
3. Let the snowflakes dry and harden for at least one day.
4. Use a small craft paint brush to lightly dust the snowflakes with shimmering luster dust.
5. You can now store the snowflakes in a container in a cool, dry place, like your pantry, for several days or weeks until you’re ready to decorate your cake.
6. After frosting your cake, press the snowflakes lightly against the buttercream before it crusts over.

I asked Heather to make a cake for New Year’s, and I was SO incredibly delighted by this cake. It had such a soft and moist texture, and we absolutely loved it. Heather was easy to contact, and was super responsive. I loved the buttercream so much. It wasn’t too sweet, it was the perfect balance, and my family raved about it.. I can’t recommend Heather’s beautiful cakes enough!
Thank you so much, Amanda! 🙂
Hi Heather I was just wondering does the champagne have to be room temperature or can I use it cold for both in the batter and buttercream.
It’s always a good idea to use room temperature ingredients when mixing cake batter, or it won’t mix and bake as evenly. I would just keep it at room temp, then open the bottle right before using it for the cake batter. For the champagne reduction in the buttercream, it won’t make too much difference if it’s chilled or not.
Does this recipe work non-high altitude locations?
Eva, you would need to make some adjustments for lower altitudes, such as decreasing the flour a little and increasing the leavening. I suggest reading this article for guidance: https://www.kingarthurbaking.com/learn/resources/high-altitude-baking
I made this into cupcakes. Filled them about 3/4 full and baked for 16 minutes. It worked out great! I thinned the frosting out a smidge with some cream and the whole family loved it!
That’s great! I’m glad to know the recipe works for cupcakes, too.
Hi there, I was wondering how you made your cute snowflakes (or where you bought them) for this cake? Thanks. 🙂
Ellie, in the FAQs section, I provided a link to the snowflake cutters I used. I cut them out of white fondant, then placed them on the cake. 🙂
I made this at sea level and it is delicious. I made it for my grandmothers wedding – doubled the recipe and made three 9” rounds and three 6” rounds for a two tiered cake. I also subbed the cake flour for 1 cup all purpose flour less two tablespoons, add two tablespoons of cornstarch
I made this cake in Vermont (Altitude 200’) and it came out perfect! No variations, it was moist and fluffy with a subtle champagne flavor. Paired it with a homemade raspberry filling and Cream-cheese frosting. Pictures @sweet_madge on Instagram 🙂
That’s great that it works at low altitude, too!
How many cups of icing does your recipe make? Working on my daughter’s wedding cake.
Thank you
Karin Overby
It makes about 5 cups of buttercream.
Hi! I live in southwest Virginia and used this recipe without making any adjustments. The cake turned out AMAZING! It’s moist and fluffy, and oh so good! It smells and tastes so fancy!
I’m so glad you love it!
i’m an amateur and baked this at sea level with no adjustments, in two 9 in pans for about 20 min. it came out a little dense and moist, but it tastes great! plus i am serving it two days after baking so i don’t think anyone will notice it’s a bit dense as it will dry out a bit. forgot to add the champagne reduction to the buttercream, but added some orange zest to the buttercream filling. delish! thank you!
Since you’re at sea level, you likely need more leavening to give it more rise so that it’s not dense.
