Ingredients & Substitutions
All-Purpose Flour: 2 ½ cups (300g) of flour provides the essential structure for our soft, pale yellow sponge cake layers. You will also need an additional ½ cup (60g) for the golden streusel coating.
Granulated Sugar: 1 ½ cups (300g) sweetens the cake and helps achieve a tender crumb. You’ll need an extra ¼ cup (50g) for the streusel.
Unsalted Butter: 1 cup (226g) of softened butter is creamed into the cake batter for richness. An additional ¼ cup (57g) of cold, cubed butter is required for the crumbly streusel.
Large Eggs: 4 whole eggs provide the necessary lift, binding, and natural pale yellow hue to the sponge cake layers.
Fresh Lemons (Zest & Juice): You will need 3 tablespoons (45ml) of fresh lemon juice and 2 tablespoons (12g) of fresh lemon zest to flavor the cake. Reserve a small piece of fresh bright yellow lemon peel to twist for the garnish.
Buttermilk: 1 cup (240ml) of room-temperature buttermilk guarantees a thick, soft, and deeply moist sponge cake.
Baking Powder & Baking Soda: 2 teaspoons (8g) of baking powder and ½ teaspoon (3g) of baking soda ensure the thick cake layers rise beautifully.
Mascarpone Cheese: 16 oz (450g) of chilled mascarpone cheese is the luxurious, velvety base for the thick, smooth white filling and frosting.
Heavy Whipping Cream: 1 ½ cups (360ml) of very cold heavy cream is whipped into the mascarpone to make it spreadable, light, and perfectly smooth.
Powdered Sugar: 1 ½ cups (180g) of powdered sugar sweetens and stabilizes the mascarpone frosting. You’ll need an extra 2 tablespoons (15g) for the final dusting on top of the cake.
Fresh Green Mint: 1 tiny fresh green mint sprig is required per slice for a vibrant, aromatic garnish.
Vanilla Extract & Salt: 2 teaspoons (10ml) of vanilla and 1 teaspoon (6g) of kosher salt enhance all the foundational flavors in the cake and frosting.
Equipment Needed
- Two 8-inch or 9-inch round cake pans
- Stand mixer or electric hand mixer
- Baking sheet lined with parchment paper (for the streusel)
- Offset spatula (for spreading the mascarpone cream)
- Fine mesh sieve (for the powdered sugar dusting)
Step-by-Step Instructions
Step 1: Bake the Buttery Golden Streusel
Preheat your oven to 350°F (175°C). In a small bowl, whisk together the ½ cup (60g) of flour and ¼ cup (50g) of sugar. Cut in the ¼ cup (57g) of cold, cubed butter using a pastry blender or your fingers until the mixture resembles coarse, wet sand.
Spread the crumb mixture evenly onto a parchment-lined baking sheet. Bake for 12-15 minutes, or until the streusel turns a deep, buttery golden-brown. Remove from the oven, let it cool completely, and crumble it into small, uniform pieces.
Step 2: Mix and Bake the Pale Yellow Lemon Sponge
Keep the oven at 350°F (175°C) and grease two round cake pans, lining the bottoms with parchment paper. In a medium bowl, whisk together the 2 ½ cups (300g) of flour, baking powder, baking soda, and salt.
In a stand mixer, cream the 1 cup (226g) of softened butter with the 1 ½ cups (300g) of granulated sugar and lemon zest until light and fluffy (about 3 minutes). Beat in the eggs one at a time, then mix in the vanilla extract and lemon juice. The batter should begin taking on a lovely pale yellow color.
Alternate adding the dry ingredients and the 1 cup (240ml) of buttermilk to the mixer, beginning and ending with the dry ingredients. Mix until just combined. Divide the batter evenly between the two pans and bake for 30-35 minutes until a toothpick inserted into the center comes out clean. Let the thick layers cool completely.
Step 3: Whip the Smooth White Mascarpone Cream
In a chilled mixing bowl, beat the cold 16 oz (450g) of mascarpone cheese on medium speed for 1 minute just to soften it. Pour in the 1 ½ cups (360ml) of cold heavy whipping cream and the 1 ½ cups (180g) of powdered sugar.
Whip on medium-high speed until thick, stiff peaks form. The resulting frosting should be pure, creamy white and flawlessly smooth. Do not overmix, or the mascarpone will curdle.
Step 4: Assemble the Cake
Place one cooled, pale yellow lemon sponge cake layer onto a cake stand or serving plate. Spread a thick, even layer of the creamy white mascarpone filling over the top using an offset spatula.
Place the second sponge cake layer on top. Use the remaining rich white mascarpone cream to frost the entire outside (top and sides) of the cake, ensuring a smooth, fully coated surface.
Step 5: Coat, Dust, and Garnish
Take handfuls of the cooled, buttery golden streusel crumbs and gently press them into the thick mascarpone frosting all over the top and sides of the cake. Ensure the cake is completely coated in a thick layer of the golden crumbs.
Using a fine mesh sieve, give the entire cake a generous powdered sugar dusting. Slice the cake and serve on a simple white ceramic dessert plate. Garnish each individual slice with a small twist of fresh bright yellow lemon peel and a tiny sprig of fresh green mint right before serving.
Expert Tips for Success
- Room Temperature Ingredients: Ensure your eggs and buttermilk are at room temperature so the lemon sponge batter emulsifies correctly, trapping air for a softer crumb.
- Chill the Bowl: When whipping the mascarpone and heavy cream, a chilled metal bowl ensures the fat stays solid, yielding the smoothest white mascarpone cream possible.
- Cool the Crumb: Let your buttery golden streusel cool completely before pressing it into the cake; otherwise, the residual heat will melt the mascarpone frosting.
- Don’t Skimp on Garnish: The fresh bright yellow lemon peel twist and fresh green mint sprig are essential for the aromatic, bakery-style finish.
Storage & Reheating/Freezing
Because of the dairy-rich mascarpone cream, this cake must be stored in the refrigerator. Keep it in an airtight cake dome or wrapped loosely in plastic wrap for up to 4 days.
If you want to freeze the cake, it is best to freeze the un-frosted pale yellow lemon sponge layers wrapped tightly in plastic wrap for up to 3 months. Thaw overnight in the fridge before making the mascarpone cream and assembling.
What to Serve With This
If you’re planning an extravagant full-course meal, this bright, citrusy dessert is the ultimate palate cleanser. Start your dinner off right with a light lemon orzo pasta salad or a comforting bowl of tiktok lasagna soup.
For your main entrée, serve a vibrant grilled mediterranean bowl or cozy up with a hearty chicken pot pie pasta. If you are creating a full dessert spread for a party, this Italian Lemon Cream Cake pairs incredibly well alongside a classic cheesecake recipe or a fun, bubbly raspberry sherbet champagne float.
Frequently Asked Questions
Yes! In fact, making the cake a day in advance allows the flavors to meld beautifully in the fridge. Just wait to add the buttery golden streusel crumbs and powdered sugar until right before serving to maintain the crispy texture.
While cream cheese can work in a pinch, it has a tangier flavor and firmer texture. Mascarpone cheese is essential for authentic Italian Lemon Cream Cake, providing a richer, smoother, and sweeter white cream filling.
Store leftover Italian Lemon Cream Cake in an airtight container or under a cake dome in the refrigerator for up to 4 days. Because of the mascarpone frosting, it should not be left at room temperature.
Using whole eggs and fresh lemon juice/zest provides a naturally gorgeous pale yellow color. Avoid overbaking, as browning the edges too much can detract from the bright, vibrant color of the crumb.
Mascarpone has a high fat content and can split or curdle easily if over-whipped or if the heavy cream isn’t cold enough. Whip the mixture just until stiff peaks form, and always use chilled dairy.
