Ingredients for alvin zhou 150 hour cake
Twelve ingredients, 150 hours of patience—this cake transforms humble pantry staples into restaurant-quality perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 3 cups | Cold, cubed for cake layers |
| Granulated Sugar 🍚 | 4 cups | Superfine preferred for smoothness |
| Almond Flour 🌰 | 3 cups | Blanched, finely ground |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for light texture |
| Large Eggs 🥚 | 12 whole | Room temperature, separated |
| Vanilla Extract 🌿 | 2 tbsp | Pure Madagascar bourbon |
| Almond Extract 🌰 | 1 tbsp | Pure, high-quality |
| Baking Powder 🍞 | 1 ½ tsp | Double-acting preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Heavy Whipping Cream 🥛 | 4 cups | 36% fat, cold |
| Powdered Sugar 🍚 | 6 cups | Sifted for buttercream |
| Slivered Almonds 🌰 | 1 cup | Toasted for garnish |
| Almond Paste 🌰 | 1 cup | High-quality, smooth |
The butter and almond flour are non-negotiable here. European-style butter (like Plugrá or Bérurier) has higher fat content for better flavor and creaminess. For almond flour, Bob's Red Mill is reliable, but if you're feeling fancy, blanch your own almonds and grind them fresh—the flavor difference is night and day. Eggs should be organic, free-range if possible, as they yield richer yolks for the buttercream. The vanilla and almond extracts? No imitation here—stick with pure bourbon vanilla and high-quality almond extract, like McCormick's or Lalique. These are the ingredients that make this cake sing.
No almond flour? Substitute with 2 cups ground almonds, but toast them first to deepen the flavor. Running short on butter? Vegetable shortening works in a pinch, though it won’t taste as rich. For the buttercream, if you can’t find 36% cream, whip heavy cream with 2 tbsp powdered sugar first, then fold in the butter. The almond paste is tricky to find—Trader Joe’s or Whole Foods usually carry it, or you can blend almond flour with a little almond extract and a splash of water. Pro tip: Toast your slivered almonds in a dry pan for 2-3 minutes until golden—they’ll add a nutty crunch that elevates the whole cake.
Buttercream keeps for up to 5 days in the fridge, covered tightly. The cake layers? Wrap individually in plastic and store in the fridge for up to 3 days before assembling. For long-term storage, freeze the fully assembled cake (without frosting) for up to 3 months. When ready to serve, bring it to room temperature for 2-3 hours—this is key for those crisp edges and melt-in-your-mouth texture. Leftovers? Slice and freeze in airtight containers for up to a month. Trust me, it’s even better the second time around.

Step-by-step instructions for Alvin Zhou's 150-Hour cake
Here's how to build this legendary cake layer by layer, ensuring perfect texture and flavor at every stage.
Prepare the Cake Batter with Precision
Begin by combining the 3 cups unsalted butter and 4 cups granulated sugar in a stand mixer fitted with the paddle attachment. Cream on medium speed for 5-7 minutes until the mixture is light, fluffy, and nearly doubles in volume. This step is critical—it incorporates air that will create that signature tender crumb. I like to scrape down the sides every minute to ensure even mixing.
Next, add the 12 whole large eggs, one at a time, mixing well after each addition. The batter should become smooth and slightly thickened. In a separate bowl, whisk together the 3 cups almond flour, 1.5 cups all-purpose flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. Gradually add the dry mixture to the wet ingredients, alternating with the 2 tablespoons vanilla extract and 1 tablespoon almond extract, mixing just until combined. Overmixing here will develop gluten, so stop as soon as the batter is homogeneous.
Bake the Cake Layers to Perfection
Preheat your oven to 350°F and prepare three 8-inch round cake pans by lining the bottoms with parchment paper. Divide the batter evenly among the pans, smoothing the tops with a spatula. Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. The layers should be golden and just set—don't overbake, or they'll dry out during the long resting period.
Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely. This resting time is crucial—it lets the layers set properly before assembly. I usually let them cool for at least 2 hours at room temperature before proceeding. If you're short on time, you can refrigerate them for 1 hour to speed up the process, but room temperature is ideal for the best texture.
Create the Almond Buttercream Filling
In a separate bowl, beat the 4 cups heavy whipping cream until it forms soft peaks. Gradually add the 6 cups powdered sugar, mixing until fully incorporated. Then, add the 1 cup almond paste, mixing until smooth and creamy. This buttercream should be thick but still pipeable—if it's too stiff, soften it with a splash of milk or cream. The almond paste adds a subtle depth of flavor that complements the vanilla cake beautifully.
For the almond glaze, melt the remaining 1 cup unsalted butter in a saucepan over low heat, then whisk in the 1 cup almond paste and 1 cup powdered sugar until smooth. Let it cool slightly before using—it should be thick enough to coat the layers but still spreadable. This glaze will give the cake its signature sheen and add an extra layer of almond flavor.
Assemble the Cake with Precision
Place the first cake layer on a cake stand or plate, then spread a generous layer of the almond buttercream over the top. Repeat with the second layer, ensuring the buttercream is evenly distributed to prevent gaps. Press the layers together gently but firmly—this ensures they stick without squishing out the filling. Wrap the entire cake in plastic wrap and refrigerate for at least 4 hours, or overnight. This chilling step is non-negotiable—it allows the layers to fully adhere and the flavors to meld.
Once chilled, remove the cake from the fridge and apply the almond glaze evenly over the top and sides. Sprinkle the 1 cup toasted slivered almonds over the glaze while it's still wet to create a beautiful, textured finish. Let the glaze set for 30 minutes before slicing—this ensures it holds its shape and gives the cake that professional, polished look. Serve at room temperature for the best experience.
Pro Tips For Making Alvin Zhou 150 Hour Cake
- CREAM BUTTER AT ROOM TEMP: I learned this the hard way—cold butter from the fridge will give you a dense, greasy cake. Let it sit out for 2 hours (or microwave in 15-second bursts) until it’s soft but not melted. The goal is to mimic the texture of a warm stick of butter, not a puddle.
- SIFT ALMOND FLOUR LIKE FANCY BAKING: Almond flour is sneaky—it packs down and lies. Sift it twice (yes, twice) with the all-purpose flour to avoid a brick-like texture. I used to skip this and wondered why my cake turned out like a doorstop.
- DON’T OVERMIX THE BATTER: This is the thing that matters most. Once you fold in the eggs, mix just until combined—about 15 strokes max. Overmixing develops gluten, and you’ll end up with a chewy, dense cake instead of the light, airy texture Alvin’s recipe promises.
- USE A TOOTHPICK TEST—BUT WAIT: Stick a toothpick in the center and call it done when it comes out clean and the cake springs back when touched. I was skeptical until I tried it—rushing it out of the oven too soon leads to a gummy middle. Give it 5 minutes past the toothpick test.
Essential equipment for great alvin zhou 150 hour cake
Precision Mixers
Your stand mixer is the workhorse of this recipe, so invest in a high-quality model like the KitchenAid Artisan Series or Cuisinart Premium. These handle the heavy cream and buttercream with ease, especially during the 5-7 minute butter-cream stage. I’ve found the KitchenAid’s 5-quart bowl is ideal for this recipe’s volume, and the paddle attachment ensures even mixing without overdeveloping gluten. Avoid budget mixers—they struggle with dense batters and can overheat.
For the buttercream, a hand mixer works in a pinch, but it’ll take 10-15 minutes of continuous mixing. If you’re serious about baking, the Mixer’s 6-speed control lets you adjust for delicate stages like whipping cream to soft peaks. Pro tip: Keep your mixer clean—leftover almond paste residue can turn rancid quickly. 💡
Baking Pans
Use three 8-inch round cake pans with 2-inch tall sides—these are non-negotiable for even baking. I recommend Wilton Perfect Results pans with nonstick coating, but if you’re baking frequently, carbon steel pans (like Le Creuset) conduct heat better and create a crispier crust. Line the bottoms with parchment paper to prevent sticking, and grease the sides lightly with butter or baking spray.
Avoid dark-colored pans—they absorb heat unevenly and can burn the edges. If your pans are less than 2 inches tall, the cake may overflow during baking. For a crispier edge, bake in glass pans (like Pyrex) for the final layer, but monitor closely—they bake faster. 🔥
Cooling Racks
Never skip the cooling step—this cake’s texture depends on it. Invest in a large wire cooling rack (at least 18-inch diameter) to ensure even airflow. I use a OXO Good Grips rack with adjustable legs to accommodate all three pans simultaneously. Place the pans on the rack immediately after baking to prevent soggy bottoms from residual heat.
For the 4-hour chilling phase, use a large plastic wrap (like Glad Press'n Seal) to wrap the assembled cake tightly. This prevents drying and helps the layers set uniformly. If you’re short on space, a second-tier cooling rack lets you stack pans vertically while cooling. 💫
Offset Spatula
A 6-inch offset spatula (like OXO Good Grips) is essential for spreading buttercream evenly between layers. The flexible silicone edge glides smoothly, preventing gaps that can cause crumbling. Use it to create a slightly domed shape on each layer before adding the next—this ensures the final cake has clean, straight sides.
For the almond glaze, the same spatula helps spread it thinly over the top and sides. Work quickly—glaze sets in 10-15 minutes—and keep a damp cloth handy to wipe up drips. A small offset spatula (4-inch) is perfect for touching up edges after sprinkling almonds. ✨
Digital Thermometer
Precision is key with this cake, so a digital instant-read thermometer (like Thermoworks ThermaPen) ensures your buttercream reaches 68°F before piping and your oven hits 350°F accurately. I also use it to check the internal temp of the cake layers—205-210°F at the center means they’re done without overbaking.
For the almond glaze, monitor its temperature—it should be 100-110°F when applied to avoid melting the buttercream underneath. A thermometer prevents guesswork and ensures professional results every time. 🌡️

Frequently asked questions
Why does this cake need 150 hours?
The extended resting time is what creates the signature texture and flavor depth. Each hour allows the cake layers to hydrate evenly, the buttercream to set perfectly, and the flavors to meld together. The initial 2-hour cooling prevents cracking, while the 4-hour chilling after assembly ensures clean slices and prevents crumbling. Think of it as marinating for a cake!
Can I make this cake in smaller pans?
Yes, but you’ll need to adjust the baking time and layer count. For 6-inch pans, bake at 325°F for 20-25 minutes and make 4 layers instead of 3. The key is maintaining the same layer thickness (1.5 inches) and resting times. Just reduce all quantities proportionally—this cake thrives on precision, not size!
What’s the biggest mistake beginners make?
Skipping or rushing the resting periods! Many try to assemble the cake immediately after baking, which leads to soggy layers and crumbling. Always let the layers cool completely (2+ hours) before assembly, and never skip the 4-hour chilling. Patience is what transforms this from a good cake to a masterpiece.
How do I store leftovers?
Slice the cake and store in an airtight container at room temperature for up to 3 days. For longer storage, freeze slices (without glaze) for up to 1 month. To serve, let frozen slices thaw at room temperature for 1-2 hours—this restores the perfect texture. The glaze can be reapplied fresh if needed.
Can I substitute almond flour?
Not ideally—almond flour gives this cake its signature richness and moisture. As a last resort, you could use 2 cups ground almonds (toasted for depth), but the texture will be denser. For a lighter version, blend 1.5 cups almond flour + 1 cup cake flour, but the almond flavor will be less pronounced. This isn’t a swap you want to make lightly!
