Amalfi Cake Recipe: Lemon-Zest Layers with Crunchy Almond Topping

This Amalfi cake recipe brings a taste of the Italian Riviera straight to your kitchen with its signature lemon-zest layers and crunchy almond topping. 🌟 The cake's origins trace back to the Amalfi Coast, where it became a beloved dessert after World War II when coffee and rum became widely available. What makes this recipe special is the delicate balance of flavors—bright lemon zest in the sponge layers, rich coffee or rum-soaked custard, and a buttery almond crumble that adds texture.

The process is straightforward but requires patience, as each layer must be baked, soaked, and assembled carefully. You'll start with a light, airy sponge cake infused with lemon zest, then soak it in a fragrant coffee or rum custard for moisture and depth. The final touch is a golden almond topping that adds a satisfying crunch. This cake is perfect for special occasions, holiday gatherings, or when you want to impress with a dessert that feels both elegant and comforting.

What you'll end up with is a stunning layered cake that's as beautiful as it is delicious—golden layers peeking through the almond crumble, with every bite offering a harmonious blend of citrus, coffee, and nuts. The almond topping not only adds texture but also ties into the traditional Italian flavors of the Amalfi Coast. Whether you're baking for a celebration or simply craving a taste of Italy, this recipe delivers restaurant-quality results with a homemade touch.

For those looking to modernize the classic, consider using vegan custard or adding a layer of fresh berries between the sponge and custard. The key is to take your time with each step, ensuring every layer is perfectly balanced in flavor and texture. Let's get started on creating this iconic Italian dessert!

Ingredients for amalfi cake

Light sponge layers, zesty lemon, and buttery almond crunch—this Italian classic needs just 15 ingredients.

The lemon zest is non-negotiable—fresh is a must—and you'll want to zest 3-4 lemons (about 2 tablespoons total). Trader Joe's and specialty grocers often carry pre-grated zest, but it's cheaper to zest your own. For the almonds, blanched almond flour gives the best texture, but slivered almonds work in a pinch if you're in a hurry. The butter should be room temperature but not melted—press a cube between your fingers to test. If it leaves a dent, it's ready. The eggs? Room temperature makes all the difference for a light sponge.

No rum? Strong coffee or espresso works perfectly for the custard—just use the same amount. The custard soaks the layers, so don't skip it! For the almond topping, if you can't find blanched almond flour, pulse raw almonds in a food processor until fine. The brown sugar adds moisture to the crumble, so don't omit it. The powdered sugar is just for dusting between layers—sift it lightly so you don't weigh down the sponge. And if you're feeling fancy, swap the vanilla extract for vanilla bean paste—the seeds add beautiful speckles to the cake.

The almond topping keeps for 3 days in an airtight container, but the cake itself? Best eaten fresh—the custard soaks in overnight, making it moist but not soggy. If you're prepping ahead, bake the cake layers a day in advance, wrap them tightly in plastic, and store at room temperature. The custard can be made 2 days ahead and reheated gently before assembling. For serving, dust with powdered sugar and add fresh berries—raspberries or blackberries complement the lemon beautifully.

Step-by-step instructions for lemon-zest layers with crunchy almond topping

Here's how to build this showstopping Italian cake layer by layer.

In a medium saucepan, combine the 1 cup heavy cream, 0.5 cup dark rum, and 0.5 cup brown sugar. Bring to a gentle simmer over medium heat until the sugar dissolves completely. Remove from heat and let cool for 5 minutes. This step prevents scrambling when you add the eggs later.

In a separate bowl, whisk together the 6 whole large eggs and 2 tbsp lemon zest until smooth. Slowly pour the warm cream mixture into the eggs while whisking constantly. Return the mixture to the saucepan and cook over low heat, stirring continuously with a wooden spoon, until it thickens enough to coat the back of the spoon—about 8-10 minutes. The custard should be thick but still pourable. Pour into a bowl, cover with plastic wrap (touching the surface), and chill in the refrigerator for at least 2 hours.

Preheat your oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper. Sift together the 3 cups all-purpose flour, 2 tsp baking powder, and 0.5 tsp salt in a large bowl. Set aside.

In a stand mixer fitted with the paddle attachment, cream the 1.5 cups unsalted butter and 2 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. Add the 6 whole large eggs one at a time, mixing well after each addition. Scrape down the sides of the bowl, then add the 1 tbsp vanilla extract and mix for another 30 seconds. Gradually add the dry ingredients, mixing on low speed just until combined. Divide the batter evenly among the prepared pans.

Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean. Let the layers cool in the pans for 10 minutes, then transfer to a wire rack to cool completely. This cooling step is crucial for clean slicing later.

Place the first cake layer on a serving plate. Spread ⅓ of the chilled lemon custard evenly over the top, leaving a ½-inch border uncovered. Dust the border with ⅓ of the 0.25 cup powdered sugar to prevent crumbs. Repeat with the remaining layers and custard.

In a small bowl, combine the 1.5 cups almond flour and 0.5 cup ground almonds. Press this mixture firmly over the top layer, creating a smooth, even surface. This almond crust gives the Amalfi Cake its signature texture and flavor.

Cover the assembled cake with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. This chilling time allows the flavors to meld and the cake to set properly. The longer it chills, the more pronounced the lemon flavor becomes.

Before serving, dust the top with the remaining ⅓ of powdered sugar** for a beautiful finish. Slice into wedges and serve at room temperature. The contrast of the moist lemon layers, rich custard, and crunchy almond topping makes each bite unforgettable. Pair with a dollop of whipped cream for an extra touch of indulgence.

Lemon Custard Variations

For a brighter twist, infuse your custard with 1 tsp lemon extract along with the zest. I’ve found this adds a more intense citrus flavor without altering the texture. If you prefer a boozy note, swap the rum for ½ cup Grand Marnier—it adds a floral depth that pairs beautifully with the lemon. For a non-alcoholic option, use ½ cup orange juice instead of rum, balancing the lemon with a complementary citrus sweetness.
