Ingredients for 100 layer cake
Precision-baked layers, delicate fillings, and flawless fondant create this showstopping masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 6 cups | Sifted for aeration, plus extra for dusting |
| Granulated Sugar 🍚 | 3 cups | Superfine preferred for smooth texture |
| Unsalted Butter 🧈 | 2 cups | Cold, cubed, 50% fat content |
| Large Egg Whites 🥚 | 12 whole | Room temperature for stability |
| Vanilla Extract 🌿 | 2 tbsp | Pure Madagascar bourbon |
| Baking Powder 🧂 | 1 ½ tsp | Diamond Crystal brand recommended |
| Salt 🧂 | ½ tsp | Fine sea salt for balance |
| Jam Filling 🍓 | 2 cups | Raspberry or apricot preserves |
| Light Custard Filling 🥛 | 1 ½ cups | Vanilla bean-infused |
| White Fondant 🎂 | 4 lb | Premium quality, 1600-1700 bloom |
| Powdered Sugar 🍚 | 2 cups | For dusting between layers |
| Cornstarch 🌾 | 1 tbsp | For fondant smoothness |
| Glycerin 💧 | 1 tsp | For fondant elasticity |
| Edible Luster Dust ✨ | 1 oz | Pearl white for elegant finish |
The flour and sugar form the foundation of these paper-thin layers. King Arthur or Gold Medal flour yields the best structure, while superfine sugar dissolves completely for silky texture. For butter, Plugrá or European-style brands provide superior fat content—critical for layering. Egg whites must be separated meticulously; even a trace of yolk can cause instability. Mise en place is non-negotiable: measure every ingredient precisely before starting. The mandoline should be set to 1/8-inch thickness for uniform layers—any thicker and the structural integrity suffers.
Substitutions require careful consideration. Cake flour can replace all-purpose at a 1:1 ratio, but add 1 tsp cornstarch per cup to prevent crumbling. For sugar, turbinado or raw sugar works but may leave granular texture—pulse in a food processor first. Egg whites can be replaced with aquafaba (3 tbsp per egg white) but require whipping to stiff peaks. The custard filling can be made with coconut milk for dairy-free adaptation, though texture will differ slightly. Fondant alternatives like buttercream or ganache exist, but neither achieves the same clean, elegant finish—this is where the 100-layer technique truly shines.
Storage demands precision. Assembled cake must rest 24 hours at room temperature before refrigeration to allow fondant to set properly. Once chilled, it keeps 5-7 days in an airtight container. For long-term storage, wrap tightly in plastic and freeze for up to 3 months—thaw overnight in the fridge before serving. The fondant layer should be dusted with powdered sugar between assembly stages to prevent sticking. Work in a 50-55°F environment for optimal fondant handling; humidity above 60% creates sticking issues.
Why You’ll Love This Recipe
- No Mixer Needed: The egg whites stiffen like magic—no stand mixer required. I’ve done this with a whisk and a bowl, and honestly? The layers are lighter than my mood on a Sunday morning.
- Butter-Sugar Whip: That butter-sugar combo? It’s the secret weapon. The sugar dissolves into the butter just enough to keep every layer moist but not sticky—like a hug from your favorite baker.
- Birthday or Breakfast: Slice it for a party or pack it for lunch. Between us, I’ve had it cold, room temp, and even reheated (yes, it’s that good), so it’s my go-to for any excuse—or no excuse at all.
- Pantry Staple Magic: Five ingredients, zero specialty items. The flour, sugar, and butter you already own will make this happen, and the leftovers? They disappear faster than I can say “second slice.”
Step-by-step instructions for creating a 100 layer cake
Precision and patience transform simple ingredients into architectural dessert art.
Prepare the Cake Layers
Preheat your oven to 350°F and prepare three 8-inch round cake pans with parchment paper liners. In a stand mixer fitted with the paddle attachment, cream together the 2 cups unsalted butter and 3 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. This step incorporates air, which is critical for the delicate texture of each layer.
Add the 12 whole large egg whites one at a time, mixing just until each is incorporated. Then add the 2 tablespoons vanilla extract, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. Sift in the 6 cups all-purpose flour gradually, mixing on low speed until just combined. Avoid overmixing—the batter should be smooth but slightly lumpy. Divide the batter evenly among the three prepared pans.
Bake and Assemble the Cake Structure
Bake the layers for 25-30 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely. Once cooled, level the tops if necessary using a serrated knife.
Place the first layer on a cake stand or plate. Spread 1 cup jam filling evenly over the top, leaving a ½-inch border uncovered. Repeat with the second layer, using the remaining 1 cup jam filling. For the third layer, use the 1.5 cups light custard filling instead of jam. This layered filling strategy creates the signature “100 layers” illusion through strategic placement.
Prepare the Fondant Bridge
Roll out half of the 4 lb white fondant on a lightly floured surface to ⅛-inch thickness. Cut a strip approximately 1-inch wide and 12-inches long to serve as the bridge between layers. Knead the remaining fondant with 1 tablespoon cornstarch and 1 teaspoon glycerin to improve elasticity and prevent cracking.
Roll out the remaining fondant to ¼-inch thickness and cut into 12 identical circles slightly larger than the cake layers. These will form the decorative “layers” that create the visual effect. Dust each circle lightly with powdered sugar to prevent sticking, then carefully place them on top of the cake, spacing them evenly to create the layered appearance.
Apply Fondant and Final Touches
Using the fondant bridge, gently press it between two cake layers to create the illusion of multiple tiers. Cover the entire cake with a thin layer of the remaining fondant, smoothing it with your hands to eliminate air bubbles. This technique, called “draping,” ensures a seamless finish that highlights the layered design.
Once the fondant is fully applied, dust the cake with 2 cups powdered sugar using a fine-mesh sieve for an elegant, snowy appearance. Finally, apply the 1 oz edible luster dust using a soft brush in circular motions to add a subtle sheen. Allow the cake to rest for 30 minutes before slicing to ensure the fondant sets properly and the layers hold their shape.
Pro Tips For Making 100 Layer Cake
- WHISK EGGS TO STIFF PEAKS: I learned this the hard way—half-cooked layers from underwhipped egg whites ruin everything. Beat those whites until they hold a sharp peak when you lift the whisk, even if it takes 5 minutes. No shortcut here; fluffy layers depend on it.
- MELT BUTTER SLOWLY: Skip the microwave for butter—melt it gently in a bowl over simmering water (double boiler) until it’s just liquid, not steaming. I used to rush it, and the cake turned dense. Patience here means lighter layers.
- SIFT FLOUR BEFORE MIXING: This isn’t the prettiest method, but it’s the tastiest. Sift the flour with sugar first—it aerates the batter and prevents lumps. I skip this when I’m lazy, but the difference in texture is noticeable.
- CHILL BATTER 30 MINUTES: Let the batter sit covered at room temp before baking. I was skeptical until I tried it—this helps the layers rise evenly and prevents sinking. No, it won’t double in size, but it’ll bake more reliably.
Troubleshooting your 100 layer cake
Cake Layers Too Thick
If your cake layers aren’t paper-thin, your mandoline might be set too high. Adjust the blade to 1/16-inch thickness for precision—any thicker and the structural illusion suffers. I recommend a Dehiller mandoline with fine-adjustment knobs for consistent cuts. Always test on a scrap cake layer first to verify thickness before slicing the full batch. 🌟
Fondant Cracking or Stretching
Fondant cracks when too dry or handled roughly. Knead in 1 tsp glycerin and 1 tbsp cornstarch to improve elasticity, then work quickly in a 50-55°F environment. Avoid over-stretching—use a damp cloth to smooth seams instead. If cracks appear, cover with a thin fondant patch and re-smooth. Humidity above 60% is the enemy here. ⚡
Layers Not Aligning Properly
Use a cake dowel (or wooden skewer) to support each layer while assembling. Insert it through the center of the first layer before adding filling, then stack carefully. Misalignment ruins the visual effect—take your time! I also recommend a leveling guide (like a Wilton cake leveler) to ensure each layer sits perfectly flat. A crooked start means crooked finish. 💡Filling Leaking Between Layers
Jam or custard leaking? Spread fillings sparingly—just enough to coat the layer without pooling. Use a palette knife for even distribution, leaving a ½-inch border uncovered. Chill the cake for 15 minutes between layers to help fillings set. For extra security, brush the cake edges with egg white before adding fondant. 🍓
Fondant Not Adhering
Dust cake layers with powdered sugar before applying fondant—this prevents sticking. If fondant still refuses to stick, lightly dampen the cake surface with water (use a spray bottle) and reapply. Avoid excess moisture, though—too much causes fondant to slide. A fondant smoother (or acrylic roller) helps press it into place without tearing. ✨
Cake Collapsing After Baking
Overmixing batter or opening the oven too soon causes collapse. Mix only until combined—lumpy is fine—and bake at 350°F for exactly 25-30 minutes. Let cakes cool 10 minutes in pans, then transfer to racks. If layers still sink, your oven runs hot—reduce temp to 325°F next time. Patience here pays off! 🔥

Frequently asked questions
How do I achieve perfectly even layers for a 100-layer cake?
A mandoline slicer set to 1/16-inch thickness is essential for precision. Always test on a scrap cake layer first, and use a serrated knife to trim any uneven edges. For extra stability, chill baked layers for 10 minutes before slicing to prevent crumbling.
Can I use buttercream instead of fondant for this cake?
Buttercream won’t create the same delicate, layered visual effect as fondant, but you can still make it work! Use a lightly sweetened whipped cream or Italian meringue buttercream for a lighter texture, then pipe thin “bridges” between layers. The result will be less crisp but still impressive.
What’s the best way to store a completed 100-layer cake?
Store at room temperature for up to 24 hours to let the fondant set properly. After that, refrigerate in an airtight container for 5-7 days. For longer storage, freeze (wrapped tightly) for up to 3 months. Always bring to room temperature before serving to prevent condensation.
How many people does this cake actually serve?
While it looks like it serves hundreds, each “layer” is just a decorative fondant circle! This recipe serves 12-15 people as a full cake. For a larger gathering, consider making two cakes or using the same technique with a 12-inch pan for more substantial portions.
What if I don’t have a mandoline slicer?
Use a sharp serrated knife and a ruler to guide even cuts. Place the cake on a cutting board, mark 1/16-inch lines with the ruler, and slice carefully. For extra precision, freeze the cake for 15 minutes before cutting to make it firmer. Practice on a test layer first!
