Reduce the champagne until syrupy — if it’s too thin, the flavor won’t shine through.

Make the champagne reduction the day before and keep it covered in the fridge.

Replace the champagne with prosecco or sparkling rosé for a different twist.

In The Test Kitchen

When I tested these champagne cupcakes, I wanted a recipe that actually tasted like champagne instead of something sweet with bubbles in the background. Reducing the champagne first was the game changer — it concentrates the flavor so it comes through in both the cupcake and the buttercream without making the texture heavy or dense. The batter stays light, the crumb tender, and the frosting has that subtle, grown-up sparkle that makes these perfect for New Year’s, anniversaries, or any celebration.

Ingredient Notes

A selection of baking ingredients, perfect for making Champagne mini cupcakes, including a bottle of sparkling wine, butter, eggs, sugar, a flour canister, salt shaker, milk, and jars—all set on a white background.

Brut or Extra Brut for the cleanest flavor.

Prosecco or cava work well.

High-quality unsalted butter at room temperature.

Salted butter works, but skip the added pinch of salt in the frosting.

Heavy Cream or Whole Milk

Heavy cream gives the softest crumb.

Sifted powdered sugar for the smoothest buttercream.

None recommended for this style of frosting.

Step By Step Instructions

Reduce the champagne

Simmer ⅔ cup champagne until you have 6 tablespoons. Let it cool completely before using.

Prep Time: 25 minutes

Cook Time: 12 minutes

Total Time: 37 minutes

Serves 24

For the Mini Cupcakes:

▢ 2/3 cup champagne or sparkling wine (Brut or Extra Brut)
▢ 1¼ cups all-purpose flour
▢ 1¼ teaspoons baking powder
▢ ¼ teaspoon salt
▢ ¾ cup granulated sugar
▢ ¼ cup unsalted butter (at room temperature)
▢ 2 large eggs
▢ 2 teaspoons vanilla extract
▢ ¼ cup champagne reduction (from above)
▢ ¼ cup heavy cream or whole milk

For the Champagne Buttercream:

▢ 10 tablespoons unsalted butter (at room temperature)
▢ 2.5 to 3 cups confectioners’ sugar (sifted)
▢ 2½ tablespoons champagne reduction (from above)
▢ 1 teaspoon vanilla extract
▢ Pinch of salt (to taste)
▢ Edible gold glitter spray (for a festive finish)

In a small saucepan, simmer 2/3 cup champagne over medium heat until it reduces to 6 tablespoons total (about 10–12 minutes).
Remove from heat and let cool completely.
Preheat the oven to 350°F (177°C) and line a 24-cup mini muffin tin with cupcake liners.
In a small bowl, whisk together the flour, baking powder, and salt. Set aside.
In a medium mixing bowl, beat the butter and sugar together until light and fluffy, about 2–3 minutes.
Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
In a small cup, combine ¼ cup champagne reduction with ¼ cup cream or milk.
Add the dry ingredients to the butter mixture in three parts, alternating with the champagne-cream mixture. Begin and end with dry ingredients. Mix until just cobined—do not overmix.
Fill each cupcake liner about 2/3 full (about 1 tablespoon of batter).
Bake for 11–13 minutes, or until a toothpick inserted in the center comes out clean.
Cool cupcakes in the pan for 5 minutes, then transfer to a wire rack to cool completely before frosting.
In a medium bowl, beat the butter on medium-high speed until light and creamy, about 2 minutes.
Gradually add 2.5 cups of confectioners’ sugar, mixing on low after each addition.
Add the champagne reduction and vanilla extract, then beat until fluffy and smooth.
Adjust the texture by adding more sugar (to thicken) or a splash of cream (to loosen), as needed.
Add a pinch of salt to taste to balance the sweetness.
Pipe the buttercream onto cooled cupcakes using a piping bag fitted with a star tip (like Wilton 1M or 2D).
Hold your edible gold glitter spray about 6–8 inches away and mist a light coat over the frosted cupcakes for a sparkly finish.
Let the glitter dry for a few minutes before serving or storing.

Erren’s Top Tips

Don’t skip cooling the champagne reduction — warm reduction can melt the butter in the batter.
If the batter seems slightly thick, that’s okay. Overmixing will toughen the crumb.
Use a small cookie scoop for even cupcake sizes.
For extra champagne flavor, brush the tops of the cooled cupcakes lightly with a teaspoon of reduction before frosting.

Variations & Add-Ins

Strawberry Champagne Cupcakes: Fold ¼ cup finely diced strawberries into the batter.
Rosé Cupcakes: Replace the champagne with sparkling rosé for a soft pink hue.
White Chocolate Drizzle: Drizzle melted white chocolate over the frosted cupcakes for a luxe finish.
Confetti Version: Add 2 tablespoons of rainbow sprinkles to the batter for birthday celebrations.

Storage & Freezing

Store frosted cupcakes in an airtight container for up to 3 days at room temperature.
Freeze unfrosted cupcakes for up to 2 months. Thaw at room temperature, then frost fresh.
You can freeze the champagne reduction in an airtight container for future batches.
