Ingredients for alex guarnaschelli coconut cake
Velvet crumb meets toasted coconut crunch—just these 13 ingredients transform into Guarnaschelli’s signature cake.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | 1 cup | Room temperature, full-fat preferred |
| Granulated Sugar 🍚 | 2 cups | Superfine preferred for smooth texture |
| Light Brown Sugar 🍚 | ½ cup | Packed, for moisture |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted, no substitutions |
| Coconut Flour 🥥 | ¼ cup | Not coconut powder, sifted |
| Baking Powder 🧂 | 2 tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality |
| Coconut Milk 🥥 | 1 can | Full-fat, refrigerated |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Unsweetened Shredded Coconut 🥥 | 2 ½ cups | Freshly toasted, not sweetened |
| Powdered Sugar 🍚 | 1 cup | For dusting |
| Toasted Coconut Oil 🫒 | ½ tbsp | For topping crispiness |
The butter matters here—use European-style if you can, but any good unsalted works. King Arthur or Fleischmann’s flours are my go-tos for this recipe, but any all-purpose will do. Coconut flour is non-negotiable—it’s what gives that signature moisture without heaviness. Toast your coconut in a dry pan over medium heat for 5-7 minutes until golden and fragrant—don’t skip this step. For the coconut milk, grab the full-fat canned kind (like Thai Kitchen)—the richness is key. Eggs should be at room temp, so pull them out 30 minutes before baking.
No coconut flour? Substitute with extra all-purpose flour (reduce by 1/4 cup), but the texture won’t be quite the same. Running short on vanilla? Almond extract works at half the amount. For the coconut milk, coconut cream from a can thickened with a bit of powdered sugar is a decent swap. The brown sugar can be swapped for white, but you’ll lose that subtle caramel depth. Pro tip: Sift your dry ingredients together to avoid a dense crumb—trust me, it makes all the difference.
This cake keeps beautifully—3 days covered at room temp or 5 days refrigerated. For extra freshness, store layers between parchment paper. The topping stays crisp for 2 days if kept airtight. Freeze the whole cake (unfrosted) for up to 3 months—thaw overnight in the fridge. Want to make ahead? Bake the layers and topping separately, then assemble just before serving. The aroma alone will have everyone thinking it’s from a bakery.
Why You'll Love This Recipe
- Here’s what sold me: you’re using basic pantry staples (butter, sugar, flour) but the coconut flour transforms it into something special—no pricey specialty ingredients needed. And leftovers? They’re always there, because it’s the kind of cake that disappears faster than you can say “second slice.”
- No-Mix Fuss: I swear by this recipe because it’s literally one bowl—just cream the butter and sugars, toss in the flours (that coconut flour? It’s a game-changer for texture), and bake. No sifting, no folding until it’s almost too late, no stress. My hands stay clean, my kitchen stays tidy, and somehow, it still rises like a dream.
- Tropical Comfort: The brown sugar caramelizes into something buttery and deep, while the coconut flour adds this subtle, toasty nuttiness that makes every bite feel like a hug. Honestly, it’s the kind of cake that tastes even better the second day—if you can wait that long.
- Birthday or Brunch: This cake is my go-to for anything: slice it for a weekday breakfast with coffee, stack it for a birthday cake (no one will guess it’s not from a bakery), or even crumble it over ice cream. The rich, moist crumb holds up to frosting or fruit—whatever you’re craving.
Step-by-step instructions for alex Guarnaschelli's coconut cake
Let's make this ultra-moist cake with its signature toasted coconut crunch topping.
Cream Butter and Sugars Together
In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter on medium speed until completely smooth and creamy—about 2-3 minutes. This ensures no graininess remains. Gradually add the 2 cups granulated sugar and 0.5 cup light brown sugar, mixing on medium-high speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume.
Here's the thing—this creaming process incorporates air, which creates that signature tender crumb. You'll know it's ready when the mixture is pale and ribbons form when the paddle is lifted. Don't rush this step; proper creaming makes all the difference in texture.
Mix in Eggs and Wet Ingredients
Add the 4 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 tbsp vanilla extract and 1 can coconut milk. Mix just until combined—about 30 seconds total. The batter should be smooth but not overly thick.
I like to scrape down the sides of the bowl with a spatula at this point to ensure everything is evenly incorporated. The coconut milk adds richness and helps create that signature moist texture. If the mixture looks curdled, don't worry—it'll smooth out once we add the dry ingredients.
Combine Dry Ingredients and Fold Gently
In a separate bowl, whisk together the 2.5 cups all-purpose flour, 0.25 cup coconut flour, 2 tsp baking powder, and 0.5 tsp salt. Sift the dry ingredients directly into the wet mixture and mix on low speed for 30-45 seconds until just combined. Overmixing develops gluten, which can make the cake tough.
Remove the bowl from the mixer and gently fold in the 2.5 cups unsweetened shredded coconut using a silicone spatula. Be careful not to overmix—just combine until the coconut is evenly distributed throughout the batter. The coconut gives this cake its signature tropical flavor and texture.
Prepare the Toasted Coconut Topping
While the cake batter rests, prepare the topping by melting the 0.5 tbsp toasted coconut oil in a small saucepan over low heat. Stir in 1 cup powdered sugar and mix until smooth. Remove from heat and stir in 1 cup of the shredded coconut from the batter. Let this mixture cool slightly while you prepare the cake pan.
This topping is what gives the cake its signature crunchy finish. The coconut oil helps create a glossy, crisp layer that contrasts beautifully with the soft cake beneath. If the mixture thickens too much while cooling, you can thin it slightly with a teaspoon of coconut milk.
Bake and Top the Cake
Preheat your oven to 350°F. Grease a 9-inch round cake pan and line the bottom with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
As soon as the cake comes out of the oven, immediately spread the cooled coconut topping evenly over the top. The residual heat from the cake will help set the topping and create that perfect contrast between the soft cake and crispy topping. Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
Pro Tips For Making Alex Guarnaschelli Coconut Cake
- Whip Butter First: Cream the unsalted butter and sugars until it’s pale, almost fluffy—about 3-5 minutes with a stand mixer. I learned this the hard way: skipping this step leaves the cake dense, and the coconut flavor gets lost in a heavy texture. (Yes, even if you’re impatient like me, resist the urge to rush.) ---
- Sift That Coconut Flour: Coconut flour is dense and clumpy—sift it with the all-purpose flour to avoid lumps in your batter. I used to just dump it in, and the cake turned out gummy in spots. A fine mesh sieve makes all the difference, especially when mixing with the wet ingredients. ---
- Don’t Overmix the Batter: Once you add the wet ingredients, mix just until combined—overmixing develops gluten and turns the cake tough. Fold gently with a spatula; the batter will look shaggy, but that’s how you get a light, airy crumb. (Your future self will thank you.) ---
- Rotate the Pan Mid-Bake: This cake bakes unevenly—rotate the pan 180 degrees halfway through (around 25-30 minutes). I was skeptical until I tried it: the edges cook evenly, and you avoid a raw center or overbrowned top. Sounds weird, but it works.
Troubleshooting great alex guarnaschelli coconut cake
Dense Center Issue
If your cake comes out with a dense center despite baking for the full 40 minutes, it’s likely due to undercreaming or overmixing. First, ensure your butter is properly creamed—it should be light and fluffy, not greasy. If you skipped the 3-4 minutes of creaming, the cake won’t hold enough air for a tender crumb. Also, check your oven temperature with an oven thermometer—many home ovens run 25°F hotter or cooler than set. Adjust to 325°F if needed for a slower, more even bake. 🌡️
Cracked Top Fix
Cracks often appear when the cake bakes too quickly or the oven is too hot. To prevent this, avoid opening the oven door during the first 20 minutes of baking. If cracks still form, try baking at 325°F instead of 350°F for 5-10 minutes longer. For a quick fix, cover the cracks with a thin layer of coconut topping or dust with extra powdered sugar before serving. Honestly, this is a common issue with coconut cakes—they’re worth the minor imperfections!
Dry Texture Problem
A dry cake usually means the coconut milk wasn’t fully incorporated or the batter sat too long before baking. Whisk the coconut milk vigorously before adding it to the batter, and bake within 30 minutes of mixing. If your cake still turns out dry, try reducing the flour by 1-2 tablespoons next time. For extra moisture, brush the cooled cake layers with a simple syrup made from ¼ cup sugar + ¼ cup water before assembling. This trick works wonders for restoring that signature velvet texture. ✨
Topping Not Crispy
The topping might be sticky or soft if the coconut oil wasn’t properly melted or if the mixture cooled too much before applying. Heat the coconut oil until it’s just melted (not hot) and stir in the powdered sugar until completely smooth. Spread the topping immediately after removing the cake from the oven—use a warm spatula to help it set faster. If it’s still not crispy, broil the cake for 1-2 minutes after topping to give it a final crisp. Pro tip: Toast your extra shredded coconut separately and sprinkle it on top for added crunch!
Uneven Rise
An uneven rise happens when the batter isn’t evenly distributed or the pan isn’t properly leveled. Before pouring the batter, tap the pan gently on the counter to remove any air bubbles. Also, ensure your pan is placed on the middle rack of the oven—hot spots can cause uneven baking. If your oven has a reputation for uneven heat, rotate the pan halfway through baking. For a foolproof method, bake in a 9x2-inch round pan with sides at least 2 inches tall to prevent overflow.
Storage Issues
If the cake dries out too quickly after baking, it’s likely because it wasn’t stored properly. Always wrap the cake tightly in plastic wrap or store it in an airtight container with a slice of bread (the bread helps retain moisture). For longer storage, refrigerate the cake and bring it to room temperature before serving. If the topping loses its crunch, simply toast it again in the oven at 300°F for 3-5 minutes before serving. Trust me, a little extra effort keeps this cake tasting fresh for days! 💪

Frequently asked questions
Can I substitute regular flour for coconut flour in this recipe?
While you can use regular flour, the texture will differ significantly. Coconut flour absorbs more liquid and adds that signature tropical moisture. If substituting, reduce all-purpose flour by 1/4 cup and add 2 extra tablespoons of coconut milk to maintain the cake's tenderness.
How do I know when the cake is fully baked?
The cake is done when a toothpick inserted in the center comes out clean, but look for subtle clues too. The edges should pull away from the pan, and the top should spring back gently when pressed. Baking times vary by oven—if unsure, check at 35 minutes to avoid overbaking.
Can I make this cake gluten-free?
Yes! Replace the 2.5 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). Add 1/2 teaspoon xanthan gum to help bind the crumb. The coconut flour can stay as-is since it's naturally gluten-free. Expect a slightly denser texture but still delicious.
Why does the cake need to cool before slicing?
Letting the cake cool completely (at least 1 hour) prevents crumbly slices. The residual heat helps set the structure, while cooling allows the coconut topping to crisp properly. If you can't wait, slice carefully and serve warm—but the texture won't be as perfect.
What's the best way to reheat leftover cake?
For the best results, wrap a slice in a damp paper towel and warm in the microwave for 10-15 seconds. The moisture prevents drying. If reheating the whole cake, cover with foil and warm at 300°F for 10 minutes—this restores the topping's crispness without overcooking the cake.
