Strawberry Layer Cake Ingredients
For the Sponge
• Champagne – Adds a unique flavor and moisture to the cake; sparkling wine can be a delightful substitute.
• All-Purpose Flour – Creates the cake’s structure; a gluten-free flour blend works well for those with dietary needs.
• Baking Powder – Ensures a lovely rise in the sponge; always check its freshness for best results.
• Unsalted Butter – Brings richness and moisture; swap with vegan butter for a dairy-free option.
• Granulated Sugar – Sweetens the sponge perfectly; brown sugar can enhance the flavor profile.
• Eggs – Contribute to the cake’s texture and richness; use aquafaba as an egg-free alternative.
For the Strawberry Mousse
• Heavy Cream – Essential for a luscious mousse; full-fat coconut cream makes a great non-dairy substitute.
• Fresh Strawberries – Provide vibrant color and natural sweetness; consider raspberries for an exciting variation.
• Gelatin – Stabilizes the mousse for a beautiful texture; agar-agar serves as a vegan alternative.
• Vanilla Extract – Elevates the overall flavor; almond extract can offer a delightful twist.
Step‑by‑Step Instructions for Strawberry Layer Cake
Step 1: Prepare Dry Ingredients
Begin by preheating your oven to 350°F (175°C) and greasing two 9-inch round cake pans. In a large mixing bowl, whisk together 2 cups of all-purpose flour and 1 tablespoon of baking powder until well combined. This step is crucial for ensuring an even rise in your Strawberry Layer Cake, creating that light and fluffy texture everyone loves.
Step 2: Cream Butter and Sugar
In another bowl, cream together 1 cup of unsalted butter and 1 ½ cups of granulated sugar using a hand mixer or stand mixer on medium speed until the mixture is light and fluffy, about 3-5 minutes. Then, add in 4 large eggs one at a time, mixing well after each addition. The mixture should appear pale and airy, providing the foundation for a moist cake.
Step 3: Combine Mixtures
Gradually fold the dry ingredients into the creamed mixture using a spatula, being careful not to overmix. Once just combined, gently stir in 1 cup of champagne until your batter is smooth and well incorporated. This step brings the delightful flavor of champagne, making your Strawberry Layer Cake truly special.
Step 4: Bake
Divide the batter evenly between the prepared cake pans and smooth the tops with a spatula. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely, ensuring they don’t become soggy.
Step 5: Make Strawberry Mousse
While the cakes cool, prepare the strawberry mousse. Puree 2 cups of fresh strawberries in a blender, then strain the puree to remove seeds. In a small bowl, dissolve 1 tablespoon of gelatin in 2 tablespoons of warm water, and fold this into the puree along with 1 cup of whipped heavy cream. The mousse should be fluffy and light, ready for layering.
Step 6: Assemble Cake
Once the cake layers are completely cool, trim the tops with a serrated knife to level them. Place one layer on a serving plate and brush it generously with champagne syrup. Spread a layer of strawberry mousse on top, allowing some to overflow for a beautiful ombré effect. Repeat with the second layer, stacking it gently on top.
Step 7: Crumb Coat
Apply a thin layer of buttercream frosting over the entire cake to create a crumb coat. This seals in crumbs and ensures a smooth surface for the final layer. Chill the cake in the refrigerator for about 20 minutes to set the crumb coat. This step helps achieve a flawless finish when applying the outer layer of frosting.
Step 8: Decorate
Finally, frost the entire cake with your favorite buttercream or cover it with fondant for an elegant touch. Decorate the top with fresh strawberries, edible flowers, or gold leaf for that stunning presentation. Your Strawberry Layer Cake is now ready to impress, creating a beautiful centerpiece for any celebration.

How to Store and Freeze Strawberry Layer Cake
Fridge: Store the cake tightly covered in the refrigerator for up to 3 days. This keeps it fresh and delicious, perfect for after-celebration indulgence.
Freezer: If you want to enjoy the Strawberry Layer Cake later, wrap individual slices in plastic wrap followed by aluminum foil. Store in the freezer for up to 2 months.
Thawing: To thaw, simply transfer the wrapped cake to the fridge for several hours or overnight. This helps maintain its delightful texture and flavor.
Reheating: For a quick refresh, warm a slice in the microwave for about 10-15 seconds. Enjoy it slightly warm for an extra cozy treat!
Make Ahead Options
These Champagne & Strawberry Layer Cake components are perfect for meal prep, allowing you to enjoy celebration time without the kitchen stress! You can prepare the sponge and strawberry mousse up to 24 hours in advance; simply bake the cake layers and cool them completely before tightly wrapping them in plastic wrap. The mousse can be mixed and stored in the refrigerator, but be sure to give it a gentle stir before layering to maintain that fluffy texture. When ready to serve, assemble the cake with the mousse layers and apply a crumb coat, chilling briefly to set before frosting. This way, you’ll have a stunning dessert that’s just as delicious, saving you valuable time for your special gathering!

Champagne & Strawberry Layer Cake Recipe FAQs
How do I choose ripe strawberries for the cake?
Absolutely! Look for strawberries that are bright red, firm to the touch, and have a sweet fragrance. Avoid those with dark spots all over, as they might be overripe. You want the strawberries to be fresh so that they contribute to the luscious flavor of the mousse.
What’s the best way to store leftover cake?
Very important! Store your Champagne & Strawberry Layer Cake tightly covered in the refrigerator for up to 3 days. This keeps it fresh and moist. Alternatively, if you’re not planning to consume it right away, you can freeze individual slices wrapped in plastic wrap and then aluminum foil for up to 2 months.
Can I freeze the strawberry mousse?
No, I don’t recommend freezing the mousse itself because the texture may change and become grainy once thawed. However, you can prepare the mousse a day in advance and store it in the refrigerator in an airtight container. It will be just as delightful when you’re ready to assemble your cake!
What if my cake layers sink in the middle after baking?
Oh no! If that happens, it might be due to underbaking or opening the oven door too early. To prevent this, always test your cake layers with a toothpick; it should come out clean when they’re done. If they do sink, you can trim the tops evenly and still layer them with mousse for a scrumptious creation!
Are there any allergy-friendly substitutions I can make?
Certainly! For a gluten-free option, replace all-purpose flour with a certified gluten-free flour blend. If you’re accommodating a dairy allergy, use vegan butter in the sponge and full-fat coconut cream instead of heavy cream when making the mousse. Replacing eggs with aquafaba—three tablespoons per egg—also works wonders for a vegan version, ensuring everyone can enjoy this delightful cake!
