Ingredients for alex guarnaschelli coconut cake

Toasted coconut crust meets tender vanilla cake—just eight ingredients for a dessert that feels like a hug.

The coconut is everything here. Unsweetened shredded coconut from the bulk bin at Whole Foods or Trader Joe's gives the best texture—none of that sweetened junk. Toast it in a dry pan for 3-5 minutes until golden and fragrant (that nutty aroma is non-negotiable). For the coconut milk, full-fat canned versions like Thai Kitchen or Aroy-D work best—they thicken beautifully. Skip the carton stuff, it's too watery. The vanilla extract? No shortcuts—imitation will taste like perfume in your cake.

No powdered sugar? Confectioners' sugar from the grocery store works fine, but if you're feeling fancy, blend granulated sugar in a food processor for 30 seconds. Running short on heavy cream? Whipped coconut cream at a 1:1 ratio keeps it dairy-free (though the frosting won't pipe as nicely). The lemon zest is optional but worth it—one organic lemon gives that bright pop. For the crust, if you can't find unsweetened coconut, toast regular shredded coconut first to burn off excess sweetness. And yes, room-temperature butter is crucial—no one wants to fight with cold lumps in their cake batter.

The cake keeps beautifully—3 days at room temperature wrapped in parchment, or 1 week in the fridge. The crust stays crisp if you store it in an airtight container with a slice of bread to absorb moisture (trust me on this). Freezes for 3 months if you wrap it like a burrito in foil. The frosting? Make it the day you serve—it softens in the fridge. I always double the recipe because this disappears faster than you can say 'Alex Guarnaschelli'—and that's saying something.

Step-by-step instructions for Alex Guarnaschelli's coconut cake recipe

Here's how to create a perfectly balanced vanilla-coconut cake with a toasted crust that'll impress anyone.

Preheat your oven to 350°F and toast the 2 cups unsweetened shredded coconut on a baking sheet for 8-10 minutes, stirring once, until it turns a beautiful golden brown. You want it to smell nutty and toasty—this is the foundation of our flavor. Let it cool completely before using, as warm coconut can make the butter melt too quickly in the next step.

While the coconut toasts, measure out the 1 cup unsalted butter and let it sit at room temperature for 30 minutes if it's cold. You'll know it's ready when it leaves a slight indentation when pressed. This ensures smooth creaming with the sugar later. In a small bowl, combine the toasted coconut with 1 tbsp lemon zest and mix well. Set aside for now—this will become our crust.

In a stand mixer fitted with the paddle attachment, beat the 1 cup room-temperature butter with the 2 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. You're looking for a texture that nearly doubles in volume and becomes pale in color—this incorporates air that will make your cake tender. Scrape down the sides of the bowl with a spatula to ensure even mixing.

Add the 4 whole large eggs, one at a time, mixing well after each addition. Then stir in the 2 tsp pure vanilla extract until fully combined. The mixture should be smooth and slightly thickened. This is where the magic happens—the vanilla enhances the coconut flavor while keeping the cake's natural sweetness in balance.

In a separate bowl, whisk together the 2.5 cups all-purpose flour (sifted), 1 tsp baking powder, and 0.5 tsp salt until evenly distributed. Gently fold this dry mixture into the butter-sugar-egg mixture in three additions, mixing just until combined. Be careful not to overmix—you should still see a few flour streaks. This prevents a dense cake.

Next, fold in the toasted coconut mixture from Step 1. You'll notice the batter becomes slightly thicker and more textured. For the 13.5 oz coconut milk, open the can and pour in just the thick cream portion (the watery part can be saved for smoothies). Fold this into the batter gently—you want to maintain as much air as possible. The coconut milk adds moisture and richness without making the cake too heavy.

Grease two 9-inch round cake pans and line the bottoms with parchment paper. Divide the batter evenly between the pans and smooth the tops. Bake in the preheated 350°F oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The edges should be golden brown, and the top should spring back slightly when pressed gently.

Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This gradual cooling prevents cracking. While they cool, you can prepare the optional frosting by whisking together the 2 cups powdered sugar, 0.5 cup heavy cream, and a pinch of salt until smooth and fluffy. This light frosting enhances the cake's natural flavors without overpowering them.

Once completely cool, place one cake layer on a serving plate and spread a thin layer of frosting. Add the second layer and frost the top and sides. Sprinkle with additional toasted coconut for texture and presentation. The contrast between the moist cake, creamy frosting, and crunchy coconut makes every bite exciting.

Slice and serve at room temperature. The cake should be tender yet sturdy, with a perfect balance of vanilla sweetness and coconut richness. The toasted crust adds a delightful crunch that complements the soft interior beautifully. Store leftovers covered at room temperature for up to 3 days or refrigerated for up to 1 week.

Flavor customization for this recipe

Spiced Variations

Add warmth with ½ tsp cinnamon and ¼ tsp cardamom to the dry ingredients for a chai-inspired twist. The spices complement the coconut beautifully while adding depth. For a tropical kick, mix in 1 tsp lime zest with the lemon zest—it brightens the entire cake. 🌶️

Chocolate Infusion

Replace ½ cup granulated sugar with ½ cup Dutch-process cocoa powder for a mocha-coconut fusion. Add ¼ cup hot coffee or espresso to the batter for extra richness—this works surprisingly well with the vanilla. The chocolate deepens the flavor while keeping the cake tender.

Fold in ½ cup chopped fresh pineapple or ½ cup diced mango after mixing the dry ingredients. The fruit adds moisture and a subtle tartness that balances the sweetness. For a more elegant touch, use ¼ cup raspberry jam swirled into the batter before baking—it creates beautiful pockets of fruit throughout.

Nutty Enhancements

Toast ½ cup chopped macadamia nuts with the coconut for a luxurious texture. The buttery flavor of macadamias pairs perfectly with coconut, adding a gourmet touch. For a crunchier finish, sprinkle toasted chopped pecans on top of the frosting before serving. Both nuts elevate the cake's texture and flavor profile.

Gluten-Free Adaptation

Swap the all-purpose flour for a 1:1 gluten-free baking flour blend (like Bob's Red Mill) and add ½ tsp xanthan gum to the dry ingredients. The texture remains moist, though slightly denser. For extra moisture, increase the coconut milk to 15 oz total. The cake still holds its shape beautifully while accommodating dietary needs. ✨

Use vegan butter (like Miyoko's) and replace the heavy cream with full-fat coconut cream** for the frosting. The flavor remains rich, though slightly more coconut-forward. For binding, ensure your gluten-free flour blend includes xanthan gum. This adaptation works surprisingly well without compromising texture. 🥥
