Instructions

Prepare the Cake Layers

Preheat & Prepare Pans:
Preheat your oven to 350°F (175°C). Grease and flour three 8-inch round cake pans (or two 9-inch pans, adjusting baking time as needed). Line the bottoms with parchment paper for easier removal.

Sift Dry Ingredients:
In a medium bowl, sift together the flour, baking powder, and salt. Set aside.

Whisk the Eggs and Sugar:
In a large bowl, beat the eggs and granulated sugar using an electric mixer on medium-high speed until the mixture becomes pale, thick, and ribbons form when the beaters are lifted (about 3–4 minutes).

Incorporate Wet Ingredients:
With the mixer on low, gradually add the melted butter. Then mix in the champagne, milk, vanilla extract, and lemon zest until just combined.

Combine with Dry Ingredients:
Gently fold in the sifted flour mixture using a spatula, being careful not to overmix to keep the batter light and airy.

Bake:
Divide the batter evenly among the prepared pans. Smooth the tops and bake for 20–25 minutes for 8-inch pans (or adjust time for larger pans). The cakes are done when a toothpick inserted into the center comes out clean.

Cool:
Allow the cakes to cool in the pans for 10 minutes, then remove them and transfer to a wire rack to cool completely.

Make the Strawberry Filling

Combine Ingredients:
In a small saucepan, combine the sliced strawberries, granulated sugar, champagne, and lemon juice.

Cook the Mixture:
Place the saucepan over medium heat and cook for 5–8 minutes, stirring occasionally, until the strawberries soften slightly and release their juices.

Cool:
Remove the mixture from the heat and let the filling cool completely. The mixture will thicken a bit as it cools.

Prepare the Champagne Buttercream

Beat the Butter:
In a large bowl, beat the softened butter with an electric mixer until creamy and smooth.

Add Powdered Sugar:
Add the powdered sugar, gradually beating on low speed until fully incorporated. Beat until light and fluffy by increasing the speed to medium-high.

Mix in Champagne & Flavorings:
Add the champagne, vanilla extract, and a pinch of salt. Continue beating until the frosting is smooth. If you prefer a subtle pink hue and extra strawberry flavor, blend in a few tablespoons of strawberry puree.

Adjust Consistency:
If the frosting is too thin, add a bit more powdered sugar; if too thick, add an extra teaspoon of champagne. Beat until you reach your desired consistency.

Assemble the Cake

Level the Cakes:
If necessary, level the tops of your cooled cakes with a serrated knife so they stack evenly.

Layer & Fill:

Place the first cake layer on a serving plate.(Optional) Brush lightly with a champagne syrup (a mix of equal parts champagne and simple syrup) for extra moisture. Spread a generous layer of the strawberry filling evenly over the cake.

Pipe or spread a layer of champagne buttercream on top.

Stack the Layers:
Place the second cake layer on top of the filling, repeat with another layer of strawberry filling and buttercream, then add the final cake layer on top.

Frost the Cake:
Smoothly use the buttercream left to cover the top and sides of the cake. For a decorative touch, you can add a swirl of extra strawberry puree or garnish with fresh strawberry slices.

Chill & Serve:
Refrigerate the assembled cake for at least 1 hour to allow the flavors to meld and the frosting to set. Before serving, let the cake sit at room temperature for about 15 minutes.

Notes & Tips

• Champagne Substitutes:
  If you’d prefer a non-alcoholic version, substitute champagne with sparkling white grape juice in both the cake and the frosting.
• Decorative Ideas:
  Top the cake with fresh strawberries, edible gold leaf, or a light dusting of powdered sugar for an elegant finish.
• Storing Leftovers:
  Keep any leftovers in an airtight container in the refrigerator. Allow the cake to return to room temperature before serving for the best flavor and texture.
