Italian Dome Cake, also known as “Zuccotto,” is a visually stunning and delightfully creamy dessert with roots in Tuscany, Italy. Its distinctive dome shape, light sponge, and luscious cream filling make it a centerpiece-worthy cake that balances elegance and indulgence. Traditionally prepared by lining a bowl with slices of sponge cake soaked in liqueur and filled with a rich blend of whipped cream, chocolate, and sometimes candied fruits or nuts, this cake is a celebration of texture, flavor, and Italian pastry artistry. It’s served chilled, which enhances its luxurious, mousse-like interior and soft cake exterior.
The origin of Zuccotto dates back to Renaissance Florence, and it’s said to be inspired by the dome of the famous Florence Cathedral, the “Duomo.” The term “zuccotto” itself means “little pumpkin” in Italian, a nod to its rounded shape. This cake was historically made in a mold shaped like a soldier’s helmet and was originally flavored with ricotta and cocoa. Over the centuries, the recipe evolved into countless variations—some filled with gelato, others with whipped cream, chocolate, or candied fruit—making it a versatile and beloved dessert across Italy.
Ingredients Breakdown
Sponge Cake: A light, airy cake made from eggs, sugar, flour, and lemon or orange zest, providing a perfect base for absorbing syrup and maintaining the dome structure.
Amaretto Syrup: Made by mixing honey with Amaretto liqueur, this syrup adds moisture and an almond-floral flavor profile.
Filling: A rich mixture of ricotta, mascarpone, powdered sugar, vanilla extract, almond extract, orange zest, and mini chocolate chips. This creamy filling is both smooth and studded with delightful chocolate bites.
Icing: A simple glaze made from powdered sugar and water, adding a glossy, sweet finish.
Decoration: Candied fruits and maraschino cherries offer classic Italian flair and a pop of color.
Step-by-Step Recipe
Begin by baking the sponge cake: Preheat your oven to 350°F (175°C) and butter and flour an 8-inch dome mold or bowl. Prepare the sponge by beating 5 large eggs with sugar, vanilla, lemon or orange zest, and salt until light and fluffy. Fold in sifted cake flour and baking powder gently. Pour the batter into the prepared pan and bake until set, about 25 minutes. Allow to cool. For the syrup, combine Amaretto and honey until fully dissolved. For the filling, mix ricotta, mascarpone, powdered sugar, orange zest, almond extract, and vanilla extract until smooth. Stir in mini chocolate chips. To assemble, line the inside of a dome-shaped bowl with plastic wrap. Slice the sponge cake and line the bowl with the slices, pressing them gently to fit the curve. Brush with Amaretto syrup. Fill with the ricotta-cream mixture, then cover with another layer of sponge cake and brush again with syrup. Cover and refrigerate for at least 6 hours or overnight. To finish, invert the cake onto a plate, glaze with icing, and decorate with candied fruit and cherries.
Tips for the Perfect Italian Dome Cake
Use a light and airy sponge to ensure proper absorption of syrup without becoming soggy. Always allow the cake to chill thoroughly to maintain the dome shape when unmolded. For best results, use full-fat ricotta and mascarpone cheeses for a richer, smoother filling. Taste the syrup and filling before assembling to adjust sweetness or liqueur strength. Line your bowl carefully with plastic wrap for easy unmolding and cleaner presentation. When brushing the cake with syrup, be generous but avoid soaking the slices completely.
Variations and Customizations
Try swapping the Amaretto for other liqueurs like Grand Marnier, rum, or coffee liqueur for a twist. Add chopped candied citrus peel or roasted nuts to the filling for added texture and flavor. Use cocoa powder in the sponge or substitute some of the flour with almond meal for a deeper nutty profile. A chocolate glaze or ganache can replace the sugar icing for a more decadent finish. In summer, you can freeze the cake and serve it semifreddo-style.
Health Considerations and Nutritional Value
While Italian Dome Cake is undoubtedly a rich dessert, it can be made lighter by using part-skim ricotta and reducing the amount of added sugar. Hazelnuts, chocolate chips, and dairy in the filling contribute protein and calcium, but also add saturated fats. Moderation is key. Homemade versions allow you to control the ingredients, avoiding preservatives and excess sugars often found in store-bought cakes. For a gluten-free alternative, use a gluten-free sponge cake base. The liqueur content can be omitted or replaced with fruit juice for a non-alcoholic version.

Italian Dome Cake with Cream Filling
Ingredients
- 1 sponge cake baked in a 9-inch tin or a pound cake sliced into ½-inch pieces (see Victoria sponge cake recipe below)
- 2 oz coffee liqueur plus 1 tablespoon or your preferred liqueur
- 4 oz semisweet chocolate broken into pieces
- 2 oz dark chocolate grated
- 10 oz heavy whipping cream
- 2 teaspoons instant espresso powder
- 1 batch Italian pastry cream Crema Pasticcera — recipe provided below
- 2 tablespoons grated chocolate or chocolate curls for garnish
- Italian Pastry Cream Crema Pasticcera — slightly adapted from Il Cucchiaio D’Argento:
- 4 organic egg yolks
- 3½ oz sugar
- 2 tablespoons flour
- 17 oz milk
- 1 teaspoon vanilla extract
- 8 oz heavy whipping cream
- 2 teaspoons instant espresso powder
Instructions
Prepare the Bowl and Line with Cake:
- Line a 2½-quart bowl generously with plastic wrap, leaving plenty of overhang to cover the top later. Cut the sponge cake in half—using a cake slicer makes this easier. Place one half of the cake at the bottom of the bowl. If using a loaf cake, slice it into triangles and arrange them like a jigsaw puzzle to cover the entire bottom and sides of the bowl. Cut a few slices from the other half into strips and use these strips to line the sides of the bowl, which only takes a few minutes and is very straightforward. Sprinkle the cake generously with your choice of liqueur; Kahlua is a great option.
Make the Pastry Cream:
- In a medium pot (off the heat), whisk together the egg yolks and sugar briskly with a wooden spoon. Gradually add the flour, mixing well into the eggs and sugar. Heat the milk until it just comes to a boil, then add the vanilla. Slowly pour the hot milk into the egg mixture in small amounts, stirring well between additions to prevent curdling. Once fully combined, place the pot over medium heat and continue stirring continuously. When the mixture boils, cook for another 3 to 4 minutes until thickened, then remove from heat. Stir as it cools to prevent a skin from forming.
- Melt the Chocolate: Melt the chocolate either in the microwave or in a heatproof bowl set over simmering water. Set aside to cool slightly.
Make the Zuccotto Filling:
- In a medium bowl, whip 10 oz (300 ml) of heavy cream with instant coffee powder until stiff peaks form; set aside. To the cooled pastry cream, add 1 tablespoon Grand Marnier, 2 oz (55 g) grated chocolate, and fold in the whipped coffee cream gently until fully combined. Spread about two-thirds of this mixture evenly into the cake-lined bowl, filling it nearly to the top but leaving a hollow center; don’t worry if it isn’t perfect, it will come together in the end.
- Fill the Zuccotto: Mix the melted chocolate into the remaining cream until the color is uniform, then spoon this chocolate cream into the hollow center of the zuccotto.
Seal the Zuccotto and Chill:
- Use the remaining cake pieces to close the top of the zuccotto. Sprinkle with additional liqueur, cover tightly with plastic wrap, and refrigerate for at least 6 hours, preferably overnight for the best flavor and texture.
Decorate the Zuccotto:
- Whip the remaining 8 oz (235 ml) heavy cream with 2 teaspoons coffee powder and 2 tablespoons sugar until stiff peaks form. When ready to serve, remove the plastic wrap from the top, place a flat plate or cake stand over the bowl, and invert the zuccotto onto the plate. Remove the bowl gently—don’t worry if the cake has cracks, it will still taste amazing. Spread the coffee-flavored whipped cream evenly over the top and create swirls or peaks as you like. Finish by sprinkling with chocolate shavings, curls, or extra grated chocolate. Chill the decorated cake for an hour if possible, though it can be served immediately if needed.
