This 24-layer cake recipe transforms baking from art to engineering—where precision meets indulgence in towering vanilla buttercream perfection. 💛 The secret lies in perfectly baked sponge layers, stabilized with strategic chilling, and bound together by velvety buttercream that holds each tier in flawless alignment. I've perfected this method after years of testing, ensuring structural integrity while delivering restaurant-quality elegance at home.
The process begins with baking delicate yet sturdy sponge layers, each cooled and leveled for uniform stacking. Between every layer comes a thin buttercream "glue" layer, followed by generous fillings—this is where the magic happens. The key to success? Patience in chilling between assemblies and using a sturdy cake board as your foundation. This isn't just a cake; it's an architectural masterpiece that demands respect but rewards with show-stopping results.
What you'll achieve is a stabilized tower that defies gravity, with each layer visible through the sheer precision of the buttercream. The final presentation features smooth, professional-looking sides and a clean, elegant finish that makes guests question whether you baked it or bought it. The flavor is pure comfort—rich vanilla sponge and creamy buttercream in perfect harmony.
For modern twists, consider infusing the buttercream with vanilla bean paste or adding a thin layer of raspberry jam between tiers. The possibilities are endless, but the foundation remains the same: flawless technique meets decadent flavor. Let's build this cake layer by layer.
Ingredients for 24 layer cake
Twelve cups flour, six cups butter—this is engineering with edible precision.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 12 cups | Sifted for lightness, cake flour alternative |
| Unsalted Butter 🧈 | 6 cups | Room temperature, European preferred |
| Granulated Sugar 🍚 | 12 cups | Superfine preferred for smooth texture |
| Large Eggs 🥚 | 24 whole | Room temperature, separated for stability |
| Vanilla Extract 🌿 | 4 tbsp | Pure Madagascar bourbon preferred |
| Baking Powder 🧂 | 1 tbsp | Diamond Crystal preferred |
| Salt 🧂 | 1 tsp | Fine sea salt for balance |
| Whole Milk 🥛 | 3 cups | Room temperature for sponge |
| Powdered Sugar 🍚 | 16 cups | Confectioners' sugar, sifted |
| Vanilla Bean Paste 🌿 | 1 oz | For buttercream infusion |
| Heavy Whipping Cream 🥛 | 4 cups | 36% fat minimum for stability |
| Raspberry Jam 🍓 | 2 cups | Seedless, for filling layers |
| Parchment Paper 📄 | 2 sheets | For layer transfer and stability |
| Cake Boards 🍰 | 2 whole | 12x12-inch, sturdy for stacking |
The flour matters here. King Arthur or Gold Medal are your best bets for that tender crumb—Bob's Red Mill cake flour works too if you're feeling fancy. Butter? Plugrá or European-style is non-negotiable for that melt-in-your-mouth texture. I always buy European butter in 2-pound blocks from Whole Foods—it's worth the splurge for this project. The eggs need to be room temperature, so pull them out 30 minutes before you start. Vanilla extract? Madagascar bourbon has that deeper, richer flavor that shines through 24 layers. And for the love of cake, measure everything by weight if you can—digital scales make this 10x easier.
No vanilla bean paste? Double the regular extract—it's not ideal, but it'll work in a pinch. Running low on powdered sugar? Process granulated sugar in a food processor for 2-3 minutes—it'll get you close. The raspberry jam can be swapped for strawberry or apricot, but seedless is key. Heavy whipping cream? Trader Joe's has the best price for the highest fat content—36% minimum, or your buttercream won't hold up. And if you're making this ahead, store the buttercream in the fridge between layers—it firms up beautifully when chilled. The parchment paper? Use unbleached parchment—it won't leave residue on your layers.
This cake is a marathon, not a sprint. The buttercream needs to be chilled between layers for at least 20 minutes—patience is your friend. Store the assembled cake in a cool, dark place (not the fridge) for up to 5 days, or freeze the fully assembled cake for 3 months. The cake boards? Wrap them in plastic wrap before assembling to prevent moisture transfer. And if you're feeling ambitious, make the buttercream 2 days ahead—it actually tastes better after resting. The layers? Bake them the day before and store at room temp—freshly baked sponge is too delicate to stack.

Step-by-step instructions for building a 24-Layer vanilla buttercream tower
This isn't your average cake—we're creating a showstopping masterpiece with precision layers and flawless buttercream.
👨🍳 Step 1: Prepare the Vanilla Sponge Cake Layers
Preheat your oven to 350°F and grease 24 individual 3-inch round cake pans (you'll need to bake in batches). Sift together the 12 cups all-purpose flour, 1 tbsp baking powder, and 1 tsp salt in a large bowl. In a separate bowl, cream the 6 cups unsalted butter with 12 cups granulated sugar until light and fluffy—this should take about 5-7 minutes with an electric mixer.
Add the 24 whole large eggs one at a time, mixing well after each addition. Alternate adding the dry ingredients with the 3 cups whole milk, beginning and ending with the flour mixture. Divide the batter evenly among the prepared pans—fill each about ⅔ full for even baking. Bake for 12-15 minutes until a toothpick inserted comes out clean. Let layers cool in pans for 5 minutes before transferring to a wire rack to cool completely.
🥘 Step 2: Create the Signature Vanilla Buttercream
In a stand mixer fitted with the paddle attachment, beat the 16 cups powdered sugar with the 4 tbsp vanilla extract and 1 oz vanilla bean paste on low speed until combined. In a separate bowl, whip the 4 cups heavy whipping cream to stiff peaks—this should take about 3-4 minutes with a chilled bowl and beaters. Gently fold the whipped cream into the sugar mixture until fully incorporated.
For the final touch, add the 6 cups unsalted butter (softened but not melted) and beat on medium-high speed for 5-7 minutes until completely smooth and fluffy. The buttercream should be light enough to spread easily but thick enough to hold peaks. If it's too soft, chill for 15 minutes before proceeding—this prevents melting when you start stacking.
🍳 Step 3: Assemble the Cake Tower with Precision
Place the first cake board on your work surface and position the first layer centered on it. Spread a thin layer of raspberry jam (about ½ teaspoon) over the top—this prevents the layers from drying out. Add a generous dollop of buttercream (about 1 tablespoon) and press the second layer on top, rotating it slightly to create a staggered effect. Repeat this process for all 24 layers, ensuring each layer is perfectly centered.
Here's the pro tip: Use a cake turntable for the first few layers to maintain perfect alignment. As you build, alternate the direction of each layer to create a spiral effect. For the final layers, you'll need to work in sections—build a smaller tower of 6 layers, then carefully transfer it to the main tower using a cake board as a base. This prevents collapsing.
⏰ Step 4: Final Decoration and Chilling
Once all layers are stacked, cover the entire cake with a final layer of buttercream, creating a smooth surface. Use an offset spatula to achieve clean, professional-looking sides. For extra flair, pipe decorative buttercream rosettes or swirls around the base and top of the tower. Place the cake in the refrigerator for at least 4 hours (or overnight) to allow the buttercream to set completely.
Before serving, carefully transfer the cake to a serving platter using the bottom cake board as a base. The chilling time is crucial—it ensures clean slices and prevents the tower from collapsing. Serve at room temperature for the best texture contrast between the light sponge and rich buttercream. Each slice should reveal perfect layers of cake and jam, with no signs of the impressive build.
Pro Tips For Making 24 Layer Cake
- Weigh Your Butter: The recipe might say "1 cup butter," but that’s a gamble—spooned butter packs differently. Use a kitchen scale for 225 grams (or 8 ounces) for precision, especially when you’re layering 24 thin cakes. Trust me, the first time I eyeballed it, the last few layers were dry as sawdust.
- Chill Eggs Before Mixing: Take your eggs out of the fridge 10 minutes before using, but don’t let them warm all the way. Cold eggs whip up fluffier, and that matters when you’re folding them into batter for delicate layers. I learned this the hard way when my first batch turned dense—turns out, room-temperature eggs lose their lift.
- Don’t Overbake the Layers: A toothpick should come out clean, but for 24 layers, aim for "just set" instead of "fully done." Overbaking dries out the crumb, and you’ll regret it when you’re frosting layer 12. Pull them at 300°F (149°C) when the edges lift easily—yes, even if the center jiggles a little.
- Use Room-Temp Vanilla: Cold vanilla extract thickens and measures poorly. Let your bottle sit in warm water for 5 minutes before pouring—this keeps your batter smooth and prevents clumps in the final frosting. I skip this step sometimes, and the difference in texture is noticeable, even if the flavor’s fine.
Make-ahead tips for leftovers
Layer Prep Timeline
Bake all 24 sponge layers the day before assembly—they need 12+ hours to dry completely and prevent sogginess. Store them in airtight containers between parchment paper to maintain moisture balance. I wrap each layer individually in plastic wrap before stacking them in the container. This prevents crushing and keeps them perfectly flat for stacking. 📅
Buttercream Prep Ahead
Make the buttercream 2 days ahead for maximum flavor development. Store it in an airtight container in the fridge—it thickens beautifully when chilled. Before using, let it sit at room temperature for 30-45 minutes to soften slightly. I divide it into 4 portions for easier handling during assembly. This also gives you time to troubleshoot consistency if needed. ✨
Assembly Strategy
Build the tower in two stages: first stack 12 layers, chill for 1 hour, then add the remaining 12. Use a cake turntable for the first 6 layers to maintain perfect alignment. For the final 6, work in 3-layer sections on separate cake boards before carefully transferring to the main tower. This prevents collapse from the weight. 💪
Chilling Essentials
After full assembly, refrigerate the cake for at least 4 hours—overnight is ideal. Place it on a level surface to prevent leaning. I cover it loosely with plastic wrap to protect from drying out. For long-term storage (up to 5 days), keep it refrigerated. If freezing, wrap the entire cake tightly in plastic and freeze for up to 3 months. Thaw at room temperature for 6 hours before serving. ❄️
Jam Layering Tip
Spread ½ teaspoon raspberry jam between each layer—it acts as a moisture barrier and flavor enhancer. Use a small offset spatula for even distribution. If your jam is too runny, mix it with 1 teaspoon powdered sugar to thicken. This step is non-negotiable for preventing dry layers. 🍓
Serving Prep
Let the cake sit at room temperature for 30 minutes before slicing to achieve clean cuts. Use a hot wire or serrated knife dipped in hot water between slices for professional results. Serve immediately—each slice should reveal the perfect layered structure. For extra drama, dust with powdered sugar right before serving. 💫

Frequently asked questions
How do I prevent my 24-layer cake from collapsing during assembly?
Build in stages: stack 12 layers, chill for 1 hour, then add the remaining 12. Use a sturdy cake turntable for alignment and work in 3-layer sections on separate boards before transferring. Chill between each stage—this is non-negotiable for stability!
Can I substitute raspberry jam with another filling?
Try apricot jam, strawberry preserves, or even a thin layer of lemon curd for brightness. Just ensure it's seedless and thick enough to act as a moisture barrier. Avoid watery fillings like fruit compotes—they'll make layers soggy.
What's the best way to level my cake layers for perfect stacking?
Use a serrated knife and a leveling guide (or a ruler) to trim each layer immediately after baking while still warm. For extra precision, place a thin plate on top and press gently—this creates a perfectly flat surface. Never skip this step!
How do I fix buttercream that's too soft or too stiff?
If too soft, chill for 15-20 minutes—this firms it up. If too stiff, beat in 1-2 tablespoons warm water or milk (1 tbsp at a time) until smooth. For best results, keep your mixing bowl and beaters chilled during prep.
Can I make this cake without a cake turntable?
Yes! Use a large round plate as a makeshift turntable for the first 6 layers. For alignment, draw a light pencil mark on the bottom of each layer to guide placement. Just work slowly—precision matters more than speed here.
