Ingredients
Cake Ingredients
- All-purpose flour: Provides structure and supports the rise of the cake.
- Granulated sugar: Sweetens and contributes to a tender, light crumb.
- Milk: Adds moisture, richness, and helps dissolve sugar for a smooth batter.
- Colored jimmies (sprinkles): Adds bursts of color and visual fun; minimal effect on texture.
- Butter: Adds richness, flavor, and contributes to a tender crumb.
- Egg whites: Provide structure, lift, and lightness to the cake.
- Cornstarch: Lightens the cake, giving a softer, finer crumb.
- Canola or vegetable oil: Keeps the cake moist without adding strong flavor.
- Baking powder: Leavening agent that ensures proper rise and fluffiness.
- Vanilla extract: Enhances sweetness and overall flavor depth.
- Salt: Balances sweetness and boosts flavor.
- Almond extract (optional): Adds a subtle nutty note and complements strawberry flavor.
Strawberry Filling Ingredients
- Strawberries: Provide fresh fruit flavor and moisture.
- Granulated sugar: Sweetens the filling and draws out fruit juices.
- Lemon juice: Adds brightness and balances sweetness.
- All-purpose flour: Thickens the filling so it holds its shape between cake layers.
Strawberry Buttercream Ingredients
- Powdered sugar: Provides sweetness and structure for smooth, pipeable frosting.
- Butter: Adds creaminess, richness, and stability.
- Crushed freeze-dried strawberries: Infuses concentrated strawberry flavor without adding excess moisture.
- Heavy cream: Adjusts frosting consistency for easy spreading or piping.
- Salt: Balances sweetness and prevents the frosting from tasting flat.
Topping
- Fresh strawberries & jimmies: Add flavor, texture, and visual appeal.
Tips To Get Your Recipe Right
- Ensure your egg whites are pristine: Any grease or leftover soap will prevent them from reaching stiff peaks, which are essential for a light, airy sponge. Even a tiny speck of yolk can ruin the fluffiness.
- Fold, don’t stir: When incorporating whipped egg whites, use a silicone spatula and gently fold them in. Overmixing knocks out the air, leaving a dense, heavy cake instead of a soft, cloud-like texture.
- Sprinkle smartly: Toss your jimmies in a small pinch of flour before folding them into the batter. This prevents them from sinking to the bottom during baking and keeps your Funfetti effect vibrant.
- Use freeze-dried strawberries in the buttercream: They provide intense strawberry flavor and natural pink color without adding excess moisture, which would otherwise curdle the frosting.
- Cool fillings completely before assembly: Your stovetop strawberry filling must be fully chilled before touching the cake. Warm filling can melt the buttercream and cause the layers to slide, ruining the structure.
Storage Tips
- Room temperature for a few hours only: Because of the fresh strawberry filling, the cake should not sit out overnight. It is safe for serving during a party, but long-term storage requires refrigeration.
- Refrigeration for 4–5 days: Place the cake in an airtight container or under a cake dome. This keeps the sponge fluffy, protects the buttercream, and ensures the strawberry filling stays safe to eat.
- Freezing slices for up to 3 months: Freeze individual slices on a plate for about an hour until the strawberry frosting is solid. Wrap each slice in plastic wrap and a layer of foil. Thaw in the fridge overnight, then let sit at room temperature for 30–60 minutes before serving to restore a soft, melt-in-your-mouth texture.
- Protect cut edges: Press parchment paper directly against any exposed sponge to lock in moisture.
- Avoid decorating too early with fresh fruit: Only add fresh strawberries immediately before serving to prevent them from weeping and making the cake soggy.
- Never cover a warm cake: Wrapping or covering while warm traps steam, which can make the sponge soggy and cause the buttercream to slide off.
- Always cover when chilling: Refrigerators pull moisture from baked goods quickly. Keep the cake in a dome or airtight container to maintain softness and prevent drying.
FAQs
Can I use frozen strawberries for the homemade filling?
Yes, frozen strawberries work perfectly for the center filling. You do not even need to thaw them first. Just toss them straight into the saucepan with your sugar, lemon juice, and flour. They will release a little extra water as they melt, so you might just need to let the mixture simmer for an extra minute or two until it gets nicely thick and jammy.
Why did my cake layers turn out dense instead of fluffy?
This usually happens during the very last step of making the batter. Because this recipe relies on whipped egg whites for its volume, you have to fold them in incredibly gently with a silicone spatula. If you use an electric mixer or stir too aggressively, you will pop all those tiny air bubbles, resulting in a flat, heavy sponge instead of a light and airy one.
Can I just use fresh strawberry puree in the frosting instead of freeze-dried berries?
It is highly recommended to stick to the freeze-dried strawberries. Fresh strawberry puree holds a lot of water, and adding that liquid to a butter-based frosting will almost instantly cause it to separate, curdle, and become a runny mess. The freeze-dried fruit gives you that gorgeous pink color and intense flavor without ruining the silky texture.
Does the cake have to be refrigerated, and how long does it last?
Yes, because of the cooked fruit filling, this cake must be kept in the fridge, where it will stay fresh for up to five days. This is especially important in warm, tropical climates; if you leave the cake out on the counter, the heat and humidity will quickly cause the buttercream to melt and slide right off the sides of your sponge.
What is the absolute best way to serve this dessert?
While it needs to be stored in the fridge, it is always best eaten at room temperature. Let your chilled slice sit out for about 30 minutes so the butter in the frosting can soften up. It makes a fantastic, bright dessert to enjoy while winding down in the evening with a good television drama or while reading a few chapters of a new book.

Directions
- Make The Funfetti Layers
- Set your oven to 350°F. Grease two 8-inch or 9-inch round cake pans so they are ready to go.
- In a clean bowl, use a mixer to beat the egg whites until they hold stiff, glossy peaks. Set this bowl aside for later.
- In a large bowl, whip the softened butter for a minute or two until it is pale and fluffy. Pour in the oil and granulated sugar, beating for another two minutes to create a wonderfully light and airy base.
- In a separate medium bowl, sift together your flour, cornstarch, baking powder, and salt.
- Alternately add your sifted flour mixture and the milk into the butter bowl. A good rule of thumb is to start with a third of the flour, mix in half the milk, add more flour, the rest of the milk, and finish with the last of the flour. Mix gently until just combined.
- Stir in the vanilla extract, the optional almond extract, and your colorful jimmies.
- Grab your whipped egg whites and gently fold them into the batter using a silicone spatula. Use a very light hand so you don't deflate the air bubbles you just created.
- Divide the batter evenly between your two prepared pans and smooth the tops.
- Bake for 20 to 22 minutes. You will know they are done when a toothpick inserted into the center comes out clean. Let the cakes cool completely before moving on.
- Simmer The Strawberry Filling
- While your cakes are cooling, combine the chopped strawberries, granulated sugar, lemon juice, and flour in a medium saucepan.
- Cook the mixture over medium heat, giving it a stir every so often, until it begins to boil. Once it boils, drop the heat to medium-low and let it simmer for 10 to 12 minutes. It will reduce into a beautifully thick, jammy filling. Make sure to let it cool down entirely before you use it.
- Whip The Strawberry Buttercream
- Beat the softened butter on its own for 3 to 4 minutes to make it incredibly light and fluffy.
- Slowly beat in 3 cups of your powdered sugar, about half a cup at a time. Next, pour in 3 tablespoons of heavy cream and mix it well. Check the consistency of your frosting. If it feels too thin, mix in a little more powdered sugar. If it feels too stiff to spread, splash in a little more heavy cream.
- Blend in your crushed freeze-dried strawberries. Give it a taste, and add a tiny pinch of salt if you want to balance out the sweetness.
- Assemble The Cake
- Place one cooled cake layer onto your serving plate and spread a very thin layer of buttercream over the top.
- Scoop about a third of your frosting into a piping bag. Pipe a thick, sturdy ring around the outer edge of the cake layer. This acts as a wall to hold the soft fruit inside.
- Spoon your cooled strawberry filling right into the center of that frosting ring. To keep the top cake layer from getting soggy, pipe a very thin layer of buttercream directly over the fruit filling and carefully smooth it out with an offset spatula.
- Place your second cake layer on top and press down very gently to secure it. Use your remaining buttercream to frost the top and sides of the entire cake.
- Decorate the top with extra fresh strawberries and more sprinkles if you like. Because of the fresh fruit filling, you will need to store any leftovers in the fridge. However, always serve the cake at room temperature. A chilled slice will soften up nicely after about 15 to 30 minutes on the counter.
