This 3-layer sponge cake recipe transforms a simple kitchen into a bakery wonderland with layers of light vanilla sponge, velvety buttercream, and fresh strawberry jam. The secret lies in precise measurements and patience—each layer must bake evenly and cool perfectly to create that signature stack magic. I've perfected this recipe after years of trial and error, ensuring every slice delivers that perfect balance of textures and flavors.
The foundation starts with three delicate sponge layers, baked just until golden with a tender crumb that crumbles at the edges. Between each layer, rich vanilla buttercream and fresh strawberry jam create a luscious filling that keeps the cake moist and flavorful for days. The key is chilling the cake between layers to prevent sliding, while the final buttercream frosting adds that professional finish.
By the time you're done, you'll have a cake that's light enough to eat with a fork yet sturdy enough to slice neatly. The vanilla sponge provides a clean, buttery base, the strawberry jam adds a burst of freshness, and the buttercream ties everything together with its creamy sweetness. This isn't just a cake—it's a showstopper that will impress even the most discerning dessert lovers.
Whether you're celebrating a birthday, anniversary, or just craving something special, this recipe delivers restaurant-quality results at home. The best part? You can customize the fillings—swap strawberry for raspberry or add a hint of citrus zest to the buttercream. Let's get baking!
Ingredients for 3 layer sponge cake
These precise ingredients create the perfect balance of light sponge, velvety buttercream, and fruity jam layers.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for lightest texture |
| Granulated Sugar 🍚 | 2 ¼ cups | Superfine preferred for smoothness |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, softened |
| Large Eggs 🥚 | 6 whole | Room temperature for best blending |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar bourbon preferred |
| Baking Powder 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Strawberry Jam 🍓 | 1 ½ cups | Fresh or high-quality store-bought |
| Heavy Whipping Cream 🥛 | 2 cups | Cold for best whipping |
| Powdered Sugar 🍚 | 4 cups | Sifted for smooth buttercream |
| Vanilla Bean Paste 🌿 | 1 tbsp | For intense vanilla flavor |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed for brightness |
| Unflavored Gelatin 🍬 | 1 ½ tsp | Bloomed in 3 tbsp cold water |
The flour and sugar are the backbone of this cake—King Arthur or Gold Medal flour gives the best rise, while superfine sugar dissolves smoothly for a tender crumb. Butter matters too: Plugrá or Land O'Lakes unsalted work best when softened to room temperature, not melted. Room-temperature eggs blend more easily, so take them out 30 minutes before mixing. The vanilla extract should be pure bourbon—Madagascar or Tahitian varieties add depth. For the jam, Smucker's or homemade strawberry preserves work perfectly, but avoid chunky jams that won't spread smoothly between layers.
No vanilla bean paste? Double the vanilla extract works in a pinch, but you'll miss that rich vanilla flavor. Substituting powdered sugar for granulated in the buttercream? Add 1/4 cup corn syrup to prevent graininess. The gelatin is key for stabilizing the buttercream—Great Lakes or Knox brands bloom perfectly. For a lighter cake, swap 1/2 cup of the buttercream for whipped cream between layers. The baking powder must be fresh: if it's more than 6 months old, test it first by mixing with water—it should bubble immediately.
Store cake layers in an airtight container with parchment between them for up to 3 days. The buttercream keeps for 5 days refrigerated or 3 months frozen in a sealed container. To assemble ahead, bake layers and frost the day before—chilling overnight prevents sliding. For a showstopper, dust with powdered sugar or add edible gold leaf before serving. The cake improves with time, so let it sit at room temperature for 1 hour before cutting into perfect slices.

- Birthday to Brunch: This cake isn’t just for celebrations—it’s my go-to for potlucks, office treats, or even a lazy weekend breakfast. Split it into squares, layer it with jam, or serve it plain. It’s the blank canvas that works for any occasion without extra effort.
- Leftovers That Last: Between us, this cake keeps for days in the fridge. I’ve wrapped slices in parchment and frozen them for impromptu desserts later. And because it’s made with pantry staples, it’s cheaper than store-bought but tastes like you spent hours baking. (Spoiler: You didn’t.)
Step-by-step instructions for 3-Layer sponge cake
Here's how to build the perfect vanilla sponge cake with flawless layers every time.
Prepare the Sponge Cake Batter
Preheat your oven to 350°F and grease three 8-inch round cake pans, lining the bottoms with parchment paper for easy removal. In a stand mixer fitted with the paddle attachment, beat the 1.5 cups unsalted butter and 2.25 cups granulated sugar on medium speed until light and fluffy, about 5-7 minutes. You'll know it's ready when the mixture nearly doubles in volume and leaves ribbons when the beaters are lifted.
Add the 6 whole large eggs, one at a time, beating well after each addition. Then mix in the 2 teaspoons vanilla extract and 1 tablespoon vanilla bean paste for that extra depth of flavor. In a separate bowl, whisk together the 3 cups all-purpose flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix—this can make your cake dense.
Bake the Cake Layers
Divide the batter evenly among the three prepared cake pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean and the tops spring back when gently touched. Rotate the pans halfway through baking for even browning. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
Here's the thing—if the tops look slightly domed, don't worry. Once cooled, they'll settle into perfect flat layers. For extra insurance, I like to level the tops with a serrated knife if they're uneven, ensuring clean, flat surfaces for stacking.
Make the Strawberry Jam Filling
While the cakes cool, prepare the strawberry jam filling. In a small saucepan, combine the 1.5 cups strawberry jam, 1 tablespoon lemon juice, and 1.5 teaspoons unflavored gelatin that has been bloomed in 3 tablespoons cold water. Heat the mixture over low heat, stirring constantly, until the gelatin dissolves completely and the jam is smooth and glossy. Remove from heat and let it cool to room temperature.
This step is crucial for a stable filling. The gelatin helps the jam set properly between the layers, preventing any soggy bottoms. If the mixture thickens too much while cooling, you can gently reheat it for a few seconds to loosen it up again.
Prepare the Buttercream Frosting
In a large mixing bowl, beat the 2 cups heavy whipping cream with an electric mixer until soft peaks form. Gradually add the 4 cups powdered sugar, mixing on low speed until incorporated. Increase the speed to medium and beat until the frosting is smooth, fluffy, and holds stiff peaks. Add the 1 tablespoon vanilla bean paste and mix just until combined.
For the perfect buttercream, make sure your whipping cream is ice cold before you start. This ensures it whips up quickly and holds its shape. If the frosting seems too thick, you can soften it slightly by adding a splash of milk, but generally, it should be just thick enough to hold its shape while still being spreadable.
Assemble the Cake Layers
Once all the layers are completely cool, it's time to assemble. Place the first cake layer on a cake stand or plate. Spread a thin, even layer of the strawberry jam filling over the top, leaving a ½-inch border uncovered. Repeat this process with the remaining two layers, ensuring each layer is evenly coated with jam.
Now, spread a generous layer of the buttercream frosting over the top of the first cake layer, again leaving a ½-inch border. Place the second layer on top and press down gently to secure it. Repeat this process with the third layer. Once all layers are stacked, cover the entire cake with a final layer of buttercream, creating a smooth, even surface. Use a spatula to create a slight overhang at the edges for a polished look.
Chill the cake in the refrigerator for at least 1 hour before slicing. This allows the filling to set and the frosting to firm up, making it easier to slice cleanly. Enjoy your stunning 3-layer sponge cake with its perfect balance of fluffy vanilla sponge, fruity strawberry filling, and rich buttercream frosting!
Pro Tips For Making 3 Layer Sponge Cake
- Whisk Eggs Until Actually Ribbon Stage: I learned this the hard way—stopping at "soft peaks" leaves your cake dense. Beat the eggs with sugar until the ribbon stretches 2-3 inches before breaking. Cold eggs? Run them under warm water first—they’ll emulsify faster and give you that light, airy texture you’re after.
- Weigh Butter, Don’t Scoop: Unsalted butter packs differently. Use a kitchen scale for precision—aim for room temp but not greasy (press a thumb in; it should leave a slight indent). Packed butter = soggy layers; melted butter = collapsed cake. No scale? Scoop into a ramekin first, then level off.
- Bake Layers Low and Slow: Your oven’s top rack is a trap. Place pans on the middle rack and reduce heat by 25°F (if your recipe says 350°F, try 325°F). This prevents doming and ensures even baking—no more underdone centers or burnt edges. Yes, it takes 5 minutes longer, but the texture’s worth it.
- Cool Layers on a Wire Rack: Stacking warm layers = a sad, flattened cake. Let each layer cool completely on a rack before filling. I know, I know—you’re eager to assemble. But rushing this step means your filling will leak out like a sieve. Patience here saves cleanup later.
Best sauces and condiments for this dish
Classic Vanilla Buttercream
The rich, velvety vanilla buttercream in this recipe is the star of the show—it's what brings all those delicate sponge layers together. I use 4 cups powdered sugar and 2 cups cold heavy whipping cream for a perfectly balanced texture that's neither too sweet nor too stiff. The secret is whipping the cream until it forms soft peaks before adding the sugar gradually. This ensures a smooth, fluffy consistency that spreads beautifully between layers. 🥛
For extra flavor depth, I always add 1 tablespoon vanilla bean paste—it's worth the small splurge over regular extract. If you're feeling adventurous, try adding ½ teaspoon almond extract for a sophisticated twist. For a lighter version, fold in ½ cup whipped cream after mixing to reduce density while keeping that signature richness.
Strawberry Jam Variations
The classic 1.5 cups strawberry jam filling is perfect, but don't be afraid to experiment! For a tangier profile, mix in 1 tablespoon lemon curd with the jam. Raspberry jam works beautifully too—just reduce the gelatin to 1 teaspoon since berry jams are naturally thicker. I've also had great success with apricot jam for a subtler, more floral flavor that pairs wonderfully with vanilla.
If you want to make it from scratch, simmer 2 cups fresh strawberries with ½ cup sugar and 1 tablespoon lemon juice until thickened. Strain through a fine-mesh sieve for a smooth, seedless filling. The fresh version adds a bright, vibrant taste that store-bought jam can't match. For a boozy twist, add 1 teaspoon Grand Marnier to the warm jam mixture before cooling.
Cream Cheese Frosting
For a tangy contrast to the sweet sponge, swap out the buttercream for a cream cheese frosting. Beat 8 oz cream cheese (softened) with 1 cup unsalted butter until smooth, then gradually add 3 cups powdered sugar and 1 teaspoon vanilla extract. This frosting has a lighter texture that's perfect for summer cakes. It also pairs beautifully with berry compotes instead of jam.
To make it extra special, fold in ½ cup whipped cream at the end for a fluffier finish. For a citrusy twist, add 1 tablespoon orange zest along with the vanilla. This frosting is particularly good with lemon or passionfruit curd fillings. The tang cuts through the richness of the sponge layers beautifully, creating a sophisticated balance of flavors.
Chocolate Ganache Drizzle
No cake is complete without a decadent finishing touch! Melt ½ cup dark chocolate chips with ¼ cup heavy cream over a double boiler, then let it cool slightly before drizzling over the assembled cake. For extra flair, add ½ teaspoon espresso powder to the melted chocolate for a mocha twist. The ganache adds a glossy sheen that makes your cake look like it came from a bakery.
For a white chocolate version, use ½ cup white chocolate chips and 2 tablespoons coconut milk for melting. Add ½ teaspoon vanilla extract and a pinch of salt to enhance the flavor. Drizzle over the cake just before serving so it stays glossy. You can also create a simple chocolate shell by melting 4 oz white chocolate with 2 oz dark chocolate for a marbled effect that's visually stunning.
Citrus Curd Filling
Brighten up your cake with a lemon or orange curd instead of jam. Cook ½ cup citrus juice (lemon, orange, or a mix) with ½ cup sugar and 2 egg yolks over low heat, stirring constantly until thickened. Strain through a fine-mesh sieve for a silky texture. This curd has a tangy sweetness that cuts through the richness of the buttercream beautifully.
For extra depth, add 1 teaspoon grated citrus zest to the curd mixture. You can also make a mixed berry curd by adding ½ cup cooked and strained berry purée (raspberry, blackberry, or strawberry) to the lemon juice. The curd works particularly well with a vanilla bean buttercream for a sophisticated flavor combination that feels both classic and modern.

Frequently asked questions
Can I use cake pans that aren't 8 inches?
Yes, but you'll need to adjust baking times and frosting amounts. For 6-inch pans, bake for 20-25 minutes and use half the batter. For 9-inch pans, bake 30-35 minutes and double the recipe. Always check doneness with a toothpick. The key is maintaining the same batter depth—about 1.5 inches—for even baking.
Why did my cake layers sink in the middle? This usually happens from overmixing the batter or opening the oven too soon.
How do I level uneven cake tops?
Use a long serrated knife or cake leveler. Place the pan on a cutting board, then gently saw back and forth across the dome. Keep the knife level with the board to create a perfectly flat surface. For extra precision, use a ruler as a guide. Leveling ensures clean layers and prevents sliding when stacking.
Can I make this cake without gelatin?
Yes, but your filling may be softer. For strawberry jam, try adding 1 teaspoon cornstarch mixed with 1 teaspoon water to thicken it before assembling. For buttercream, chill it for 2 hours before frosting to help it set. The cake will still taste great—just expect slightly softer fillings that won't hold shape as firmly.
How far ahead can I assemble the cake?
You can assemble it up to 24 hours ahead! Wrap tightly in plastic wrap and refrigerate. The flavors meld beautifully overnight. Bring to room temperature for 1 hour before serving. For longer storage, freeze the assembled cake (unfrosted) for up to 1 month
