Ingredients for alex guarnaschelli coconut cake
Twelve ingredients transform into Guarnaschelli’s signature tropical layers—crisp exterior, moist interior, and pockets of toasted coconut.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Room temperature, high-fat content |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smooth texture |
| Light Brown Sugar 🍚 | ½ cup | Packed, for moisture balance |
| Large Eggs 🥚 | 2 whole | Room temperature, separated |
| All-Purpose Flour 🌾 | 2 cups | Sifted, spooned lightly |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 1 tbsp | Pure Madagascar bourbon |
| Unsweetened Shredded Coconut 🥥 | 1 cup | Toasted until golden |
| Shredded Coconut 🥥 | 1 cup | For topping, plus extra |
| Whole Milk 🥛 | ½ cup | Room temperature |
| Vegetable Oil 🫒 | ¼ cup | Light, for crispness |
| Cornstarch 🌾 | 1 tbsp | For tender crumb |
The butter and sugars are non-negotiable here. European-style unsalted butter (like Plugrá or Land O’Lakes) creates that signature tenderness, while superfine sugar dissolves smoothly for a silky texture. For the coconut, unsweetened, freshly toasted is essential—pre-shredded loses its crunch. I source mine at Whole Foods or Trader Joe’s, where they toast it in-house for maximum aroma. The vanilla extract should be pure Madagascar bourbon—imitation extracts lack the depth Guarnaschelli’s technique demands.
No superfine sugar? Regular granulated pulsed in a food processor works, but sift it well to avoid graininess. Substituting coconut? Toasted pecans or macadamia nuts add richness, though texture will differ. For a lighter cake, reduce flour by 2 tbsp and fold in whipped egg whites instead of creaming. The cornstarch is critical—it prevents a gummy texture, so don’t skip it. If you’re baking in a high-altitude area, add 1 tbsp extra flour to compensate for the thinner air.
Store the cake in an airtight container with a layer of parchment between slices to maintain crispness. It keeps at room temperature for 3 days or refrigerated for 1 week, though I recommend serving within 48 hours for peak texture. For gifting, wrap individual slices in parchment and tie with twine—it reheats beautifully in a 275°F oven for 10 minutes to restore that buttery crunch. Freeze portions for up to 3 months by wrapping tightly in plastic.

Step-by-step instructions for alex Guarnaschelli's coconut cake
Here's how to craft this decadent tropical masterpiece with perfect layers and crispy edges.
👨🍳 Step 1: Prepare the Coconut Crust for Crispy Layers
Toast the 1 cup unsweetened shredded coconut in a dry skillet over medium heat for 3-4 minutes until golden brown and fragrant. Watch closely—it burns quickly. Transfer to a food processor and pulse until finely ground, resembling coarse sand. This creates the signature crunchy base.
In a small bowl, mix the toasted coconut with 1 tablespoon cornstarch and set aside. This combination prevents the crust from becoming gummy while adding that essential tropical texture. The cornstarch also helps absorb excess moisture during baking, ensuring crispy layers rather than soggy ones.
🍳 Step 2: Cream Butter and Sugars to Lighten the Batter
In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter (at room temperature) with the 2 cups granulated sugar and 0.5 cup light brown sugar on medium speed for 4-5 minutes. You're looking for a pale, fluffy mixture that nearly triples in volume. This thorough creaming incorporates air, which creates the cake's signature light, airy texture.
Here's the thing—don't rush this step. The butter should be completely smooth with no visible graininess. If you see any butter clumps at the bottom, let it mix another minute. The reason we wait is that proper aeration prevents dense, heavy cake layers. I've found that using room-temperature butter yields the best results—it emulsifies more evenly with the sugars.
🥘 Step 3: Combine Wet Ingredients for Perfect Moisture Balance
Add the 2 whole large eggs (at room temperature) one at a time, mixing on low speed after each addition until fully incorporated. Then add the 0.5 cup whole milk, 0.25 cup vegetable oil, and 1 tablespoon vanilla extract, mixing just until combined. The batter should be smooth with no visible streaks of flour.
I always use room-temperature eggs because they blend more smoothly into the batter. Cold eggs can create pockets of liquid that don't incorporate properly, leading to uneven texture. The vegetable oil adds moisture without adding flavor, while the vanilla extract enhances the tropical notes. At this stage, the batter should be thick but pourable—similar to heavy cream consistency.
👨🍳 Step 4: Fold in Dry Ingredients Gently
In a separate bowl, whisk together the 2 cups all-purpose flour, 2 teaspoons baking powder, and 0.5 teaspoon salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix—stop as soon as the flour disappears. Overmixing develops gluten, which can make the cake tough.
Lastly, gently fold in the 1 cup shredded coconut (for topping) using a rubber spatula. The coconut should be evenly distributed throughout the batter. This step is crucial for maintaining the cake's lightness while ensuring each slice has that signature coconut flavor and texture. The batter will be thick and slightly sticky—this is normal and indicates proper hydration.
🔥 Step 5: Assemble and Bake for Perfect Layers
Preheat your oven to 350°F. Grease and flour three 6-inch round cake pans and line the bottoms with parchment paper. Divide the coconut crust mixture evenly among the pans, pressing it firmly into the bottom to create an even layer. This forms the foundation for those crispy, flavorful layers that define this cake.
Divide the batter evenly among the prepared pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. The cakes should be golden brown with a slightly domed top. Here's the key: rotate the pans halfway through baking for even heat distribution. This ensures all layers rise uniformly and develop that perfect texture throughout.
Pro Tips For Making Alex Guarnaschelli Coconut Cake
- Cream Butter Properly: Use a stand mixer with the paddle attachment to beat the butter and sugars until it’s palely golden—not just lightened, but actively turning color. I learned this the hard way: under-creaming means a denser cake that won’t rise as well, and you’ll end up with a sad, flat coconut top. ---
- Measure Flour Right: Spoon the all-purpose flour into your measuring cup and level it off with a knife—don’t scoop directly from the bag. This recipe relies on precise ratios, and packing the flour (even slightly) will throw off the texture, making the cake gummy instead of tender. ---
- Don’t Overmix the Batter: Stop folding in the coconut and flour as soon as they’re just combined—no streaks, but no extra mixing either. Overmixing develops gluten, and this cake needs to stay light and airy. I used to ignore this and ended up with a cake that tasted more like a dense muffin. ---
- Bake Until Golden: Pull the cake out when the top springs back slowly and the edges are pulling away from the pan—then let it cool completely before checking the center. My first few times, I cut into it too soon and got a raw middle, which ruined the whole experience. Patience here makes all the difference.
Troubleshooting this dish
Dense Cake Layers
If your cake turns out dense instead of light and airy, the issue likely lies in overmixing the batter or using cold ingredients. I’ve found that creaming the butter and sugars for 4-5 minutes until pale and fluffy is critical—this incorporates air that prevents density. Also, ensure your eggs and milk are at room temperature; cold ingredients can cause the batter to set too quickly, trapping air bubbles. If you suspect overmixing, try folding the dry ingredients into the wet mixture by hand using a rubber spatula instead of the mixer. 💡
Coconut Not Toasted Enough
The signature crunch comes from properly toasted coconut, so if it tastes bland or lacks texture, you likely didn’t toast it long enough. Toast the 1 cup shredded coconut in a dry skillet over medium heat for 3-4 minutes**, stirring constantly, until golden brown and fragrant. Watch closely—it burns quickly! For extra insurance, pulse the toasted coconut in a food processor until it resembles coarse sand before mixing with cornstarch. This step is non-negotiable for that signature tropical crunch. 🥥
Cake Sticking to Pans
Coconut cake has a tendency to stick if the pans aren’t properly prepared. Always grease your 6-inch round cake pans with butter or baking spray, then dust with flour, tapping out any excess. Line the bottoms with parchment paper for extra insurance. I also recommend preheating the oven for 15 minutes before baking to ensure even heat distribution. If the cake still sticks, try using a thin layer of vegetable oil instead of butter for greasing. 🧈
Uneven Baking
Uneven baking often results from uneven heat distribution in the oven. To prevent this, rotate your cake pans halfway through baking (around 15 minutes in) for even browning. If your oven runs hot, consider lowering the temperature to 340°F and adding 5-10 minutes to the baking time. Another trick is to place a baking sheet on the lower rack to reflect heat upward. Always check for doneness with a toothpick—it should come out clean or with a few moist crumbs. 🔥
Cake Too Dry or Crumbly
A dry or crumbly cake usually means the batter was overmixed or the oven was too hot. To fix this, ensure you’re mixing just until the flour disappears when combining wet and dry ingredients. If the cake still turns out dry, try adding 1-2 tablespoons of milk or melted butter to the batter before baking. For extra moisture, brush the baked layers with a simple syrup made from ½ cup sugar and ¼ cup water before assembling. This step adds tenderness without altering the texture. 💧
Coconut Crust Too Gummy
If your coconut crust turns out gummy instead of crisp, the cornstarch wasn’t mixed properly or the coconut wasn’t toasted enough. In a small bowl, combine the toasted coconut with 1 tablespoon cornstarch and pulse in a food processor until it resembles coarse sand. Press this mixture firmly into the bottom of the pans before adding the batter. For extra crispiness, bake the crust alone for 5 minutes before adding the batter. This pre-baking step ensures a firm foundation. 🌟

Frequently asked questions
Can I make this coconut cake gluten-free?
Yes! Replace the 2 cups all-purpose flour with a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. For best results, add 1 teaspoon xanthan gum to help bind the cake. Keep the rest of the recipe identical—just ensure your gluten-free flour is sifted before measuring. The texture will be slightly denser but still delicious!
How do I store leftovers to keep them fresh?
Store the cake in an airtight container at room temperature for up to 3 days, or refrigerate for 1 week. For maximum crispness, place parchment paper between layers. To refresh stale slices, warm them in a 275°F oven for 10 minutes with a sprinkle of water on top. Freeze portions for up to 3 months by wrapping tightly in plastic.
What's the secret to that perfect tropical flavor?
The magic comes from toasting the coconut until golden and fragrant, then grinding it into a coarse sand texture. The vanilla extract (use pure Madagascar bourbon) and light brown sugar add depth, while the cornstarch prevents gumminess. Don't skip the crust layer—it's what gives that signature tropical crunch!
Can I use this recipe for a layer cake?
This recipe makes three 6-inch layers perfect for stacking. Let each layer cool completely before assembling with coconut cream frosting or whipped cream. For extra flair, toast ½ cup extra coconut and sprinkle between layers. Chill the cake for 1 hour before slicing to maintain structure.
Why does my cake have a raw center even after baking?
This usually happens if the oven wasn't hot enough or the batter was too thick. Preheat your oven for 15 minutes before baking, and check temperature with an oven thermometer. If your oven runs cool, increase the temperature to 360°F and bake for 35 minutes. For thick batters, try adding 1 tablespoon extra milk to improve flow.
