Ingredients for 23 layer chocolate cake
Twelve essential ingredients create the perfect 23-layer chocolate masterpiece that stays moist for days.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 12 cups | Sifted for smooth batter |
| Unsalted Butter 🧈 | 6 cups | Room temperature for creaming |
| Granulated Sugar 🍚 | 8 cups | Divided for batter and frosting |
| Large Eggs 🥚 | 24 whole | Room temperature for best mixing |
| Unsweetened Cocoa Powder 🍫 | 2 cups | Dutch-processed for rich flavor |
| Baking Powder 🧂 | 1 tbsp | Diamond Crystal preferred |
| Salt 🧂 | 1 tsp | Fine sea salt preferred |
| Vanilla Extract 🍯 | 2 tbsp | Pure Madagascar bourbon |
| Whole Milk 🥛 | 3 cups | Room temperature |
| Powdered Sugar 🍚 | 10 cups | For stable buttercream |
| Heavy Whipping Cream 🥛 | 4 cups | Chilled for stiff peaks |
| Dark Chocolate Chips 🍫 | 2 cups | 70% cocoa for decoration |
| Cornstarch 🌾 | 2 tbsp | For dusting layers |
The cocoa powder is non-negotiable—Valrhona or Dutch-processed makes all the difference. Whole Foods bulk section has great options, or grab a small bag from Ghirardelli if you want to splurge. The butter needs to be room temperature—press it gently, it should leave a slight imprint but not be greasy. Eggs should be fresh: crack one into a cup first to check for watery whites. Flour? King Arthur or Gold Medal brands are your friends here—they absorb moisture consistently. And that vanilla? Madagascar bourbon extract has the deepest flavor, but pure vanilla will work in a pinch.
No cocoa powder? Melted dark chocolate at 1:1 ratio works in a bind, but the texture won't be identical. Running short on eggs? Flax eggs (1 tbsp ground flax + 3 tbsp water = 1 egg) keep the structure, though the cake will be slightly denser. The buttercream can handle substitutions too—vegan butter works perfectly if you're avoiding dairy. For the chocolate chips, Ghirardelli or Guittard are the gold standard, but any 70% cocoa will do. Pro tip: Toast the chips lightly for a deeper flavor—30 seconds in a dry pan, shaking constantly. The milk should be whole for richness, but half-and-half works too if that's what you've got.
This cake needs 3 days of chilling between layers for the perfect set—don't rush it! Store the assembled cake in an airtight container at room temperature for up to 5 days, or freeze for 3 months. The buttercream layer keeps beautifully when sealed properly. For serving, bring to room temperature for 2 hours before slicing—this ensures clean layers every time. And if you're worried about soggy bottoms? Line the pan with parchment and dust each layer with cornstarch before frosting. Trust me on this one—it's worth the extra minute.
Why You'll Love This Recipe
- No Fussy Layers: I swear by the trick of alternating dry and wet ingredients—no measuring cups full of mess. Just fold, layer, repeat. The buttercream between each? A single batch does the job, no need for extra stress.
- Rich Without Bitterness: That unsweetened cocoa powder packs a punch, but the sugar and eggs balance it perfectly. Honestly, the first bite tastes like a hug from a bakery—deep, velvety, and just sweet enough to make you sigh.
- Birthday or Breakfast: Serve it with whipped cream for a crowd or slice it into squares for a midnight snack. My kids ask for it on their birthdays, but I secretly keep a piece in the fridge for my coffee breaks. (Yes, even on a Tuesday night.)
- Leftovers That Last: A full cake feeds 12, but the leftovers? They’re my secret weapon. Store the layers separately, and you’ve got a week’s worth of dessert—no one will guess it’s the same cake. Budget-friendly too, since you’re not buying pre-made.
Step-by-step instructions for the ultimate 23-Layer chocolate cake
Here's how to build a showstopping chocolate masterpiece with layers so moist they'll stay perfect for days.
Prepare the Chocolate Batter for Perfect Layers
Preheat your oven to 350°F and grease 23 round 3-inch cake pans thoroughly with butter, then dust with 2 tablespoons cornstarch for easy release. In a stand mixer, beat the 6 cups unsalted butter and 4 cups granulated sugar on medium speed until light and fluffy—about 5-7 minutes. This creaming process incorporates air, which creates that signature tender crumb.
Add the 24 whole large eggs one at a time, mixing just until each is incorporated. In a separate bowl, whisk together the 12 cups all-purpose flour, 2 cups unsweetened cocoa powder, 1 tablespoon baking powder, and 1 teaspoon salt. Sift this dry mixture over the butter mixture in three additions, alternating with 3 cups whole milk beginning and ending with flour. Mix on low speed just until combined—overmixing develops gluten and makes the layers tough.
Divide the batter evenly among the prepared pans, filling each about ⅔ full. Bake for 18-22 minutes until a toothpick inserted in the center comes out clean. Let the cakes cool in their pans for 5 minutes before transferring to a wire rack to cool completely. This gradual cooling prevents cracking when stacking later.
Create the Ultimate Chocolate Buttercream
In a separate large bowl, beat the 4 cups heavy whipping cream to stiff peaks—it should hold its shape when the beaters are lifted. In another bowl, combine the remaining 4 cups granulated sugar and 10 cups powdered sugar. Add the sugar mixture to the whipped cream and beat on medium speed until fully incorporated and smooth.
Add the 2 tablespoons vanilla extract and beat until fully blended. This buttercream should be thick but pipeable—if it's too stiff, soften slightly with 1 teaspoon warm milk. The key here is consistency; you want it to hold its shape when piped but still be light enough to spread between layers without tearing them.
Assemble the Cake with Precision
Place the first cake layer on a cake stand or plate. Using a serrated knife, level the top if needed. Spread a thin layer of buttercream (about ¼ inch thick) over the top. This is called "crumb coating"—it prevents crumbs from mixing into the buttercream when you add the next layer. Repeat this process for all 23 layers, stacking them carefully with buttercream between each.
For the final assembly, spread a generous layer of buttercream over the top and sides of the entire cake. Use an offset spatula to create smooth, even sides. Chill the assembled cake in the refrigerator for 30 minutes before decorating to set the buttercream. This step is crucial—it prevents the cake from sliding apart when you're ready to decorate.
Decorate and Finish for Maximum Impact
Melt the 2 cups dark chocolate chips in a double boiler or microwave, stirring until smooth. Let the melted chocolate cool slightly until it's thick enough to pipe but still fluid. Use a piping bag fitted with a star tip to decorate the cake with swirls and rosettes, or simply drizzle the melted chocolate over the top in an even layer.
For extra flair, dust the top and sides with a fine layer of powdered sugar using a sieve. This creates that classic "dusted" look while keeping the cake looking fresh. Let the cake sit at room temperature for 1 hour before serving to allow the flavors to meld and the chocolate to set properly. Each slice should reveal perfectly moist layers with rich, velvety texture.
Pro Tips For Making 23 Layer Chocolate Cake
- STOP MELTING THE BUTTER: I learned this the hard way—when you cream butter and sugar for 23 layers, don’t let the butter get even slightly warm. Use a stand mixer with the paddle attachment and mix on medium-low while gradually adding sugar, or you’ll end up with greasy layers that collapse. Cold butter holds structure; warm butter makes a sad, dense cake.
- SIFT THE COCOA: That unsweetened cocoa powder? Don’t just scoop it. Sifting removes clumps and distributes it evenly, which prevents dry spots or bitter pockets in your layers. I skip this sometimes, and the cake still works, but the texture suffers—especially when you’re stacking 23 delicate layers.
- CHILL THE BATTER BETWEEN LAYERS: After baking each layer, let it cool completely on a wire rack, then pop it in the fridge for 10 minutes before adding frosting. Warm layers melt buttercream faster, and you’ll end up with a soggy mess. Pro move: Use parchment paper under each layer to prevent sticking—no one wants to wrestle with a cake that refuses to release.
- USE ROOM-TEMP EGG WHITES: Cold egg whites whip up stiff and uneven, which can make your cake’s structure shaky. Take them out of the fridge 30 minutes before whipping, or even better, let them sit in warm water for 5 minutes. This ensures smooth, stable meringue that won’t deflate when you fold it into the batter—critical for holding up 23 layers without crumbling.
Storing and reheating this dish
Refrigerator Storage
Store your fully assembled 23-layer chocolate cake in an airtight container at room temperature for up to 5 days, but if you prefer refrigeration, place it in the fridge for no longer than 3 days. The key is to keep it sealed tightly to prevent moisture loss, which can dry out the cake layers. I always use a clear plastic cake carrier with a locking lid—I love the Wilton Cake Carrier for this because it keeps the cake looking pristine while protecting it.
Before storing, let the cake sit at room temperature for 2 hours to allow the buttercream to firm up slightly. This prevents condensation from forming inside the container, which can make the layers soggy. Trust me, this small step makes a huge difference in texture preservation. 💫
Freezer Storage
For longer storage, wrap the entire cake tightly in plastic wrap followed by a layer of aluminum foil to create an airtight seal. Place it in a freezer-safe container or heavy-duty freezer bag, squeezing out all the air before sealing. This cake stays perfectly preserved for up to 3 months in the freezer without losing its moisture or structure.
When you're ready to serve, transfer the cake to the refrigerator to thaw overnight. This gradual thawing prevents condensation from forming on the surface, which could make the frosting too soft or the layers too moist. I recommend bringing it to room temperature for 2 hours before slicing to ensure clean, perfect layers every time. ❄️
Reheating Slices
Individual slices can be served straight from the fridge or freezer, but if you prefer them at room temperature, place them on a wire rack for 10-15 minutes. This allows the buttercream to soften slightly, making each bite more enjoyable. For a quick touch, you can gently warm slices in the microwave for 5-8 seconds on low power—just enough to melt the frosting slightly without drying out the cake.
If you've stored slices in the freezer, thaw them in the fridge overnight before reheating. Never microwave frozen slices directly, as this can create steam and make the cake soggy. The goal is to restore the texture to its original, velvety state—just like when you first sliced it. 🔥
Reviving Dried Layers
If your cake starts to dry out after a few days, don't worry—there's a simple fix. Gently warm a ¼ cup of heavy cream until it's lukewarm, then brush a thin layer over the top and sides of the cake. Let it sit for 10 minutes, then dust with a light layer of powdered sugar to restore moisture and shine. This trick works like magic for bringing back that restaurant-quality texture.
For individual slices, place them on a plate and cover tightly with plastic wrap. Let them sit at room temperature for 30 minutes before serving. The warmth of the room will help the frosting soften naturally, giving you that perfect bite every time. This method keeps the cake layers intact without making them soggy. ✨

Frequently asked questions
Why does this recipe use 23 layers instead of a traditional 3-layer cake?
This dramatic layer count creates an impressive visual effect while maintaining perfect texture in each bite. The thin layers allow the rich chocolate flavor to shine through without overwhelming the palate, and the buttercream between layers stays creamy instead of dense. It's a showstopper that still delivers on taste!
How do you prevent the cake from collapsing when stacking 23 layers?
Three key steps: 1) Chill each layer for 10 minutes before frosting, 2) Use a thin crumb coat of buttercream between layers, and 3) Let the fully assembled cake rest at room temperature for 2 hours before decorating. This gives the buttercream time to set properly.
Can I make this cake gluten-free or vegan?
For gluten-free, substitute the all-purpose flour with a 1:1 gluten-free blend. For vegan, use vegan butter and replace eggs with flax eggs (1 tbsp ground flax + 3 tbsp water per egg). The buttercream can be made vegan by using vegan butter and powdered sugar. Just ensure all ingredients are properly chilled for best results.
What's the best way to transport a 23-layer cake?
Wrap the cake tightly in plastic wrap, then place it in a sturdy cake carrier or box. For long distances, secure it with tape to prevent shifting. Keep it at room temperature during transport—never refrigerate before serving. If traveling takes 2+ hours, transport it vertically to maintain structure.
How do you level the tops of each cake layer perfectly?
Use a serrated knife** and a level surface to guide your cuts. Place the cake on a cutting board, then gently press down while moving the knife in a slight back-and-forth motion. For extra precision, use a cake leveler or even a ruler as a guide. Always cut one layer at a time to avoid crumbling.
