Ingredients for 100 layer cake
Precision ingredients for a showstopping 100-layer cake with flawless swirls and crunchy magic.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 6 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 3 ½ cups | Divided for cake and frosting |
| Unsalted Butter 🧈 | 2 cups | Room temperature, European preferred |
| Large Eggs 🥚 | 12 whole | Room temperature, separated |
| Pure Vanilla Extract 🌿 | 2 tbsp | Bourbon or Madagascar preferred |
| Baking Powder 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Milk 🥛 | 1 ½ cups | Room temperature, whole preferred |
| Confectioners' Sugar 🍚 | 6 cups | Sifted for smooth frosting |
| Heavy Whipping Cream 🥛 | 2 cups | Cold, full-fat preferred |
| Pecans 🌰 | 1 ½ cups | Toasted, chopped for crunch |
| Brown Sugar 🍚 | ½ cup | Packed, for topping |
| Corn Syrup 💧 | ¼ cup | Light corn syrup preferred |
| Vanilla Bean Paste 🌿 | 1 tbsp | For deeper vanilla flavor |
| Cream of Tartar 🧂 | 1 tsp | For stable meringue |
The cake layers demand high-quality flour—King Arthur or Gold Medal work best for that tender crumb. European-style butter like Plugrá or President adds richness without graininess, while room-temperature eggs ensure even baking. For the vanilla, Bourbon or Madagascar extract delivers that authentic depth—imitation extracts lack the complexity. Measure your dry ingredients by weight if possible; digital kitchen scales eliminate packing errors that ruin layer consistency. The milk should be room temperature to blend seamlessly into the batter, and whole milk provides the best texture for delicate layers.
No European butter? Plugrá or Land O'Lakes unsalted are solid substitutes, though they lack the fat content. Running short on vanilla? Vanilla bean paste at half the amount intensifies flavor without liquid adjustments. For the crunchy topping, pecans from Trader Joe's stay fresher longer than store-brand varieties. The corn syrup can be swapped for light agave nectar, but it may alter caramelization slightly. Always toast your nuts—350°F for 8-10 minutes until fragrant. The cream of tartar stabilizes the meringue; if omitted, add an extra egg white to compensate. For the buttercream, confectioners' sugar from Wholesale Club is finer and dissolves more easily than grocery-store brands.
Store cake layers at room temperature in an airtight container for up to 3 days before assembly—this prevents moisture loss that causes soggy bottoms. The crunchy topping keeps for 1 week in the fridge, though it's best used immediately for maximum crunch. Buttercream can be refrigerated for 5 days or frozen for 3 months—thaw gradually at room temperature. For competition cakes, assemble the day before; flavors meld beautifully overnight. Always use parchment paper between layers to prevent sticking, and keep your work surface chilled to maintain buttercream structure during swirling.

Step-by-step instructions for vanilla buttercream swirls and crunchy topping magic
Mastering this cake requires precision and patience—each layer must be flawless.
👨🍳 Step 1: Prepare the Cake Layers
Preheat your oven to 350°F and grease 12 3-inch round cake pans (use parchment circles for easy release). Sift together the 6 cups all-purpose flour, 1.5 tsp baking powder, and 0.5 tsp salt in a large bowl. Set aside.
In a separate large bowl, cream the 2 cups unsalted butter and 1.5 cups granulated sugar on medium-high speed until light and fluffy—about 3-4 minutes. Add the 12 whole large eggs one at a time, mixing well after each addition. Scrape down the sides of the bowl as needed. Stir in the 2 tbsp pure vanilla extract and 1 tbsp vanilla bean paste.
Gradually add the dry ingredients to the wet mixture, alternating with the 1.5 cups milk, beginning and ending with the flour mixture. Mix on low speed until just combined—overmixing develops gluten and makes the cake dense. Divide the batter evenly among the prepared pans.
🔥 Step 2: Bake and Cool the Layers
Bake the layers for 18-20 minutes or until a toothpick inserted into the center comes out clean. The edges should be golden brown, but the tops may still look slightly underdone—they'll firm up as they cool. Let the layers cool in the pans for 5 minutes before transferring to a wire rack to cool completely.
Here's the thing—don't rush this cooling step. Warm layers will sweat when you frost them, causing soggy results. I like to cool them completely before leveling the tops with a serrated knife if needed. Once fully cooled, wrap each layer individually in plastic wrap and refrigerate until ready to assemble.
🍳 Step 3: Make the Vanilla Buttercream
Beat the 2 cups heavy whipping cream and 1 tsp cream of tartar in a chilled bowl until soft peaks form. In a separate large bowl, beat the 2 cups unsalted butter (softened) and 3.5 cups granulated sugar until light and fluffy. Gradually add the 6 cups confectioners' sugar and mix on low speed until combined.
Add the whipped cream mixture and 2 tbsp pure vanilla extract to the buttercream, mixing on medium speed until smooth and fluffy. This is your base frosting—it should be thick enough to hold its shape but still pipeable. If it's too stiff, add 1-2 tablespoons milk to loosen. Taste and adjust sweetness if needed.
🥘 Step 4: Assemble the Cake Layers
Place the first cake layer on a cake stand or plate. Spread a thin layer of buttercream (about ¼ inch thick) on top, then pipe a swirl of buttercream in the center. Place the second layer on top, press down gently, and repeat the process. Continue layering all 12 layers, ensuring each one is level and centered.
For the final frosting, spread a thin layer of buttercream over the entire top and sides of the cake. Use an offset spatula to create a smooth base. Now for the magic: pipe a rosette of buttercream in the center of the top layer, then gently swirl it outward with a spatula to create those signature 100-layer cake patterns. Chill the cake in the refrigerator for 1 hour to set.
🔪 Step 5: Add the Crunchy Topping
Toast the 1.5 cups pecans in a dry skillet over medium heat for 5-7 minutes, stirring frequently, until fragrant and golden brown. Let them cool completely, then chop coarsely. In a small saucepan, combine the 0.5 cup brown sugar, 0.25 cup corn syrup, and 2 tbsp butter (from your ingredients). Bring to a boil over medium heat, then simmer for 3-4 minutes until thickened slightly.
Remove from heat and stir in the toasted pecans until evenly coated. Spread this mixture evenly over the top of the chilled cake, pressing down gently to adhere. Let the topping set at room temperature for 30 minutes before slicing. The contrast of the crunchy pecan topping against the silky buttercream is what makes this cake truly special.
Pro Tips For Making 100 Layer Cake
- Weigh Your Butter: I learned this the hard way—packing butter cups with a spoon leaves too much air, making your layers denser than they should be. Use a kitchen scale for 227g (1 cup) and press it into the bowl with a fork to melt evenly. No extra grease, no dry crumbs.
- Stop When You Can’t: The cake pulls away from the pan edges before the timer dings—that’s your cue. I used to overbake, and the layers turned rubbery. Test with a toothpick: it should come out with a few moist crumbs, not wet batter or dry flour.
- Sift the Flour Twice: Yes, even if the recipe doesn’t say so. The first sift removes lumps, but the second breaks up any hidden air pockets that’ll make your cake collapse between layers. Do it right over the bowl—no flour clouds in your kitchen.
- Chill the Pans: Skip the preheating step if your kitchen’s warm. Cold pans + room-temp batter = even rise. I started leaving mine in the fridge for 10 minutes before baking, and the layers became light as cloud instead of dense as bricks.
Wine and beer pairings for these flavors
Sweet Dessert Wines
For this rich, buttery cake, a Moscato d'Asti from Italy is my go-to choice—its light, fizzy sweetness cuts through the density beautifully. The effervescence cleanses your palate between bites, making each layer taste fresh. Look for a 2022 vintage from producers like Saracco or G.D. Vajra for that perfect balance of floral notes and honeyed fruit. 🍷
Bold Red Pairings
If you prefer red wine, a Zinfandel with its jammy, spiced profile stands up to the cake's vanilla and pecan flavors. Opt for a California Zin like Ravenswood or Seghesio—their dark fruit and peppery finish complement the caramelized topping. Serve slightly chilled (55-60°F) to enhance the wine's fruitiness without overpowering the dessert.
Creamy Beer Options
A Belgian-style witbier like Hoegaarden or Stella Artois adds a refreshing contrast with its citrusy coriander notes. The light body and subtle sweetness won’t compete with the cake’s richness. For something heartier, try a honey wheat ale—breweries like Allagash make excellent options with their caramel and vanilla undertones that echo the cake’s flavors. 🍺
Coffee Liqueur Twist
For a post-dinner treat, serve the cake with a shot of Kahlúa or Tía María alongside. The coffee’s bitterness balances the cake’s sweetness, creating a sophisticated pairing. Drizzle a little over the top before serving for an extra layer of indulgence. This works especially well if you’ve added a hint of espresso powder to your buttercream.
Non-Alcoholic Pairings
Don’t overlook sparkling apple cider like Martinelli’s—its crisp acidity and subtle sweetness make it a perfect non-alcoholic match. For something warmer, try chai tea with a splash of vanilla cream, mirroring the cake’s primary flavors. A vanilla bean milkshake (made with whole milk and a touch of corn syrup) is another crowd-pleaser that complements the cake’s texture beautifully. 🥤

Frequently asked questions
How do I prevent the layers from collapsing when assembling?
Chill the cake for 1 hour after frosting to set the buttercream between layers. Use a thin layer of frosting (about ¼ inch) between each layer to prevent sogginess. Press layers gently but firmly—never force them. If layers shift, let the frosting firm up slightly before adjusting. Patience is key!
Can I make this cake in smaller pans for fewer layers?
Yes! For a 50-layer cake, use 5-inch pans and halve all ingredients. For a 25-layer cake, use 6-inch pans and reduce ingredients by 75%. Adjust baking time (+2-3 minutes per layer) since larger pans take longer to cook through. The swirling technique works the same—just scale the frosting quantity accordingly.
Why does my buttercream look grainy?
Grainy buttercream usually means undissolved sugar or improperly softened butter. Sift your confectioners' sugar thoroughly and use room-temperature butter (not melted). Beat the butter and sugar on medium-high until completely smooth before adding other ingredients. If it's still grainy, strain through a fine-mesh sieve for a silky finish.
How far in advance can I prepare the cake layers?
Bake and cool the layers, then wrap individually in plastic wrap. Store at room temperature for up to 3 days or refrigerate for 1 week. The buttercream can be made 2 days ahead and refrigerated (re-whip before using). The crunchy topping should be made fresh—it loses crispness when stored. Assemble the cake the day before serving for best texture.
Can I substitute pecans for another nut in the crunchy topping?
Try walnuts or almonds for a different texture. For a sweeter topping, use hazelnuts or pistachios. Toast all nuts until fragrant (350°F for 8-10 minutes) and chop them finely. The caramelized sugar mixture works with any nut—just adjust the amount to preference.
