Alex Guarnaschelli's Coconut Cake Recipe: Vanilla-Coconut Layers with Buttery Crispness

Alex Guarnaschelli’s coconut cake delivers the perfect balance of vanilla richness and toasted coconut crunch—layers of tender cake separated by a buttery coconut cream that melts in your mouth. 💛 The secret lies in her signature technique of flaking toasted coconut into the batter and folding it just before baking, ensuring every bite has that signature texture. I’ve recreated this recipe exactly as she would, with precise measurements and a foolproof method for achieving that signature crispness without drying out the cake.

What sets this coconut cake apart is the harmony of flavors—vanilla extract enhances the coconut’s natural sweetness while unsalted butter keeps the layers moist and rich. The cake bakes in a single pan, making it easier to handle than traditional layered cakes, yet it still delivers that impressive restaurant-quality finish. The key is patience: letting the cake cool gradually before slicing ensures clean layers and prevents crumbling.

By the time you take that first bite, you’ll taste the toasted coconut flakes crunching against the soft vanilla cake, followed by the creamy coconut cream that ties everything together. This is the kind of dessert that feels like a hug—comforting, indulgent, and impossible to resist. The recipe is designed for foolproof success, even for home bakers, with clear steps to achieve Guarnaschelli’s signature texture every time.

Perfect for special occasions or a weekend treat, this cake keeps well for 3-4 days at room temperature, making it ideal for gifting or meal prep. The method scales easily for larger gatherings, and the flavor combination works equally well with fresh or dried coconut. Let’s get baking—your taste buds will thank you.

Ingredients for alex guarnaschelli coconut cake

Eight layers of vanilla-coconut bliss with Guarnaschelli's signature buttery crunch—just these ingredients transform into restaurant-quality cake.

The unsalted butter here is non-negotiable—it's what gives those layers that melt-in-your-mouth richness. Plugrá or Land O'Lakes are my go-tos, but any good-quality brand works. Keep it cold when creaming to avoid flat cakes. For the coconut, Bob's Red Mill unsweetened shredded toasts up perfectly—look for vibrant white flakes (the yellow kind has additives). The vanilla extract matters too: Madagascar bourbon has that complex depth you taste in Guarnaschelli's version. If you're using vanilla bean paste, scrape out every bit of those seeds—worth the extra minute.

No vanilla bean paste? Double the extract and add a pinch of cinnamon for depth. Running low on baking powder? Baking soda plus cream of tartar at half the amount works in a pinch. The coconut milk can be swapped for Greek yogurt or sour cream if you're not keen on coconut flavor in the cream layer. For the sugar, superfine is ideal, but if you only have granulated, pulse it in a food processor first. The lemon zest adds brightness—skip it if you're sensitive to citrus, but trust me, it makes the coconut sing. And if you've got extra coconut milk, freeze the can for smoothies later.

This cake needs time to set—24 hours at room temperature is ideal before slicing. Store leftovers in an airtight container with parchment between layers for up to 5 days. The coconut cream layer? Make it a day ahead—it thickens beautifully overnight. For gifting, wrap individual slices in parchment and tie with twine. The cake freezes surprisingly well too: 2 months wrapped tightly in plastic. Just let it thaw at room temp before serving—never microwave, or you'll lose that crispness.

Step-by-step instructions for alex Guarnaschelli's coconut cake

Here's how to bake this showstopping cake with layers of vanilla-coconut flavor and buttery crispness.

In a stand mixer fitted with the paddle attachment, beat the 1.5 cups cold cubed unsalted butter and 2 cups granulated sugar on medium-high speed for 3-4 minutes until light and fluffy. You'll see the mixture nearly double in volume and turn pale—this is your signal that air has been incorporated perfectly. The cold butter creates fine crumbs rather than clumps, ensuring a tender crumb.

I like to scrape down the sides of the bowl every 30 seconds to make sure everything gets evenly creamed. This step is non-negotiable—properly creamed butter and sugar create those signature air pockets that make the cake light as a cloud. If your butter is too soft, chill the bowl for 10 minutes before continuing.

Add the 4 whole room-temperature large eggs one at a time, mixing on low speed after each addition until fully incorporated. Then add the 2 tbsp vanilla extract and 1 tbsp vanilla bean paste, mixing just until combined. The vanilla bean paste adds depth that regular extract can't match—you'll taste the difference in every bite.

This is where the magic happens—those egg yolks bind everything together while adding moisture. I always use room-temperature eggs because they emulsify better with the butter, creating a smoother batter. If you're worried about overmixing, don't be—this stage is forgiving as long as you don't go over 1 minute total mixing time.

In a separate bowl, whisk together the 2.5 cups sifted all-purpose flour, 2 tsp baking powder, 0.5 tsp salt, and 1 tbsp lemon zest. The lemon zest adds a bright citrus note that cuts through the coconut sweetness beautifully. Sift the flour mixture directly into the wet ingredients and mix on low speed until just combined—you should still see some flour streaks.

Overmixing develops gluten and makes the cake tough, so stop as soon as everything comes together. Here's the thing—this batter will look thick and slightly curdled, but that's normal. The coconut milk and toasted coconut we'll add next will help create that signature moist yet tender crumb. Fold in the 2 cups unsweetened shredded toasted coconut by hand using a silicone spatula.

In a small saucepan, combine the 1 can chilled full-fat coconut milk with 1.5 cups powdered sugar. Heat over medium-low heat for 3-4 minutes, stirring constantly, until the sugar dissolves completely and the mixture reaches 160°F. Remove from heat and let cool to room temperature—this prevents the cake layers from steaming when assembled.

The chilled coconut milk is crucial here—it thickens as it warms, creating that perfect custard-like filling. If you use warm coconut milk, the cake layers will become soggy. Taste the mixture and adjust sweetness if needed, but it should be sweet enough to balance the cake's richness.

Preheat your oven to 350°F and grease two 8-inch round cake pans (or line with parchment circles). Divide the batter evenly between the pans and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Rotate the pans halfway through baking for even browning.

Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. While they cool, assemble the cake by placing one layer on a plate, spreading half the coconut milk filling, then adding the second layer. Dust the top and sides generously with powdered sugar for that classic coconut cake finish. Serve at room temperature for the best texture.

This version swaps the vanilla bean paste for 1 tbsp macadamia nut paste (blend toasted macadamia nuts with 1 tbsp coconut milk until smooth) and adds ½ cup crushed macadamia nuts to the batter.
