The recipe starts with a classic Italian pan di spugna base, where lemon zest and juice infuse every bite with that signature Amalfi brightness.

For an extra touch, garnish with fresh berries or a sprinkle of edible flowers—though the cake shines on its own. Let’s get started on creating your own taste of Italy.

Ingredients for amalfi coast lemon cake

Sunshine in a box—these ingredients bring Amalfi's citrus brightness to your kitchen.

The lemons are non-negotiable here. Organic, bright yellow ones from the grocery store's produce section work best—avoid those with green patches. I grab mine from Whole Foods when I can, but any well-stocked supermarket has good lemons. For zest, use a fine grater and scrape only the yellow part, no white pith. That bitter stuff ruins everything. The butter? European-style like Plugrá or President melts better and adds richness. If you can only find regular butter, let it sit out for 2 hours before mixing.

No superfine sugar? Pulse regular granulated sugar in a food processor for 30 seconds—game-changer for smooth batter. Short on almond flour? Slivered almonds blended into a fine powder work, but texture won't be identical. The gelatin might be tricky if you've never bloomed it—just sprinkle it over cold water and let it sit for 10 minutes. No vanilla extract? Seeds from 1 vanilla bean mashed with 1 tbsp sugar works too. For the glaze, if powdered sugar clumps, sift it through a fine mesh strainer—no one wants lumpy cake.

This cake keeps beautifully—3 days at room temperature covered loosely with plastic, or 1 week refrigerated in layers separated by parchment. The filling stays fresh for 5 days in the fridge too. For make-ahead prep, bake the sponge 1 day ahead, store components separately, and assemble when ready to serve. The glaze sets quickly, so have everything ready before pouring—10 minutes max once mixed.

Step-by-step instructions for Amalfi Coast lemon cake

Here's how to create layers of zesty lemon flavor and tender crumb—just like the sun-drenched cakes of the Amalfi Coast.

In a small saucepan, combine the 0.75 cup fresh lemon juice, 0.5 cup granulated sugar, and 0.5 cup heavy cream. Bring to a gentle simmer over medium heat for 3-4 minutes until slightly thickened and fragrant. You'll see the mixture reduce slightly and develop a glossy sheen—this is your lemon syrup that will infuse every layer.

While the syrup simmers, bloom the 2 tsp unflavored gelatin in 3 tablespoons cold water in a small bowl. Let it sit for 5 minutes until fully softened but not liquid. This step ensures your filling will set properly without becoming grainy. I always use a clean, dry spoon to press down on the gelatin—this helps it absorb the water evenly.

In a medium bowl, whisk together 1.5 cups powdered sugar, 1 tbsp vanilla extract, 0.5 tsp lemon extract, and the bloomed gelatin mixture. Stir until completely dissolved and smooth. In a separate chilled bowl, whip the 1 cup heavy cream to stiff peaks—it should hold its shape when you lift the beaters.

Gently fold the whipped cream into the powdered sugar mixture using a spatula, being careful not to deflate the cream. Then add the warm lemon syrup in a slow, steady stream while folding continuously. You want to maintain that light, airy texture while incorporating all that vibrant lemon flavor. The filling should be thick but still spreadable—like a luxurious lemon curd.

Preheat your oven to 350°F and grease two 9-inch round cake pans (I use butter and flour for easy release). In a large mixing bowl, cream together the 1.25 cups unsalted butter and 2 cups granulated sugar on medium speed until light and fluffy—about 3-4 minutes. Scrape down the sides of the bowl as needed to ensure even mixing.

Add the 4 whole large eggs, one at a time, mixing well after each addition. Then whisk in the 0.5 cup fresh lemon zest, 1 tbsp vanilla extract, 1 tsp baking powder, and 0.5 tsp salt. Sift in the 2.5 cups all-purpose flour and 1.5 cups almond flour alternately, beginning and ending with the flour. Mix just until combined—don't overmix or your cake will be dense.

Divide the batter evenly between the prepared cake pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. The cakes should spring back gently when pressed in the center—that's your signal they're perfectly baked. I like to rotate the pans halfway through baking for even browning.

While the cakes are still warm, poke holes all over with a skewer and brush each layer with the remaining lemon syrup. This step ensures maximum moisture and flavor infusion. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely. The contrast of warm cake and cool filling is what makes this recipe truly special.

Once completely cooled, level the tops of the cakes if needed. Place one cake layer on a serving plate and spread half of the lemon cream filling evenly over the top. Dust the edges lightly with powdered sugar to prevent filling from oozing out. Repeat with the second cake layer and remaining filling.

For the final touch, spread a thin layer of the remaining lemon syrup over the top cake layer. Dust generously with powdered sugar for that classic Amalfi Coast look. Chill the cake in the refrigerator for at least 2 hours before serving—this allows all the flavors to meld together beautifully. Each slice should deliver that perfect balance of tender cake, tangy lemon, and creamy filling.

Dietary considerations for this dish

Gluten-Free Adaptation

Swap the 2.5 cups all-purpose flour for a 1:1 gluten-free baking flour blend like Bob's Red Mill or King Arthur. Add 1 extra tbsp almond flour to improve texture and moisture retention. I've tested this with 1.5 cups gluten-free blend + 1.5 cups almond flour—the result is still tender but slightly denser. For best results, let the batter rest for 15 minutes before baking to hydrate the blend properly. 💛

Dairy-Free Options

Replace the 1.25 cups unsalted butter with 1 cup dairy-free butter alternative like Miyoko's or Earth Balance. For the heavy cream filling, use 1 cup full-fat coconut cream chilled overnight to achieve stiff peaks. The almond flour already provides richness, so no additional substitutions are needed—just be mindful of the coconut flavor's subtle sweetness when pairing with lemons.

Nut-Free Version

Omit the 1.5 cups almond flour entirely and increase the all-purpose flour to 3 cups total. Add ½ cup ground oats for moisture and texture. The cake will be lighter but still flavorful. For the filling, use ½ cup ground oats + 1 tbsp cornstarch mixed with the powdered sugar to replace the almond flour's binding properties. The lemon flavor remains the star of the show.

Lower Sugar Adaptation

Reduce the 2 cups granulated sugar to 1.5 cups and the 1.5 cups powdered sugar to 1 cup. Use 1 tbsp erythritol or monk fruit sweetener blended with the powdered sugar to maintain volume. The lemon's natural sweetness will still shine through, though the filling may be slightly less stable. Chill the cake for an extra 30 minutes before serving to help the reduced sugar set properly.

Vegan Modifications

Replace the 4 eggs with 4 tbsp flax eggs (1 tbsp ground flax + 3 tbsp water per egg) and use ½ cup applesauce to maintain moisture. For the gelatin, use 2 tbsp agar-agar powder bloomed in 3 tbsp water instead. The texture will be slightly firmer but still delicious. I've found that vegan versions benefit from an extra 5 minutes in the oven to ensure proper doneness.
