This elegant Limoncello Mascarpone Cake combines a moist, citrus-infused olive oil crumb with a silky mascarpone frosting. Perfect for any celebration, it is finished with a tangy lemon curd for the ultimate Italian dessert experience.
Line a nine-inch pan with parchment paper and grease the sides. Preheat the oven to 345F.
In a medium bowl, whisk together the flour, baking powder, and baking soda until airy and uniform.
Stir together the milk, limoncello, and lemon juice in a measuring cup and set aside.
Build a Fragrant, Emulsified Batter
Rub the lemon zest into the sugar using your fingertips until the sugar is damp and fragrant.
Add the eggs to the sugar and beat on medium-high speed for about one minute until the mixture is pale and foamy.
With the mixer running, slowly drizzle in the olive oil, then pour in the milk and limoncello mixture until the batter is glossy and smooth.
Reduce the mixer speed to low and add the dry ingredients, mixing just until the flour disappears.
Bake, Test, and Finish with Frosting
Pour the batter into the prepared pan and bake for 40 to 50 minutes without opening the oven door prematurely.
Test the center with a toothpick, it should come out completely dry when the cake is finished.
Once the cake is fully chilled, spread the mascarpone frosting over the top and finish with dollops or a drizzle of lemon curd.
Notes
Safety Tip: Respect the two-hour safety rule for dairy-based desserts when serving at room temperature.Storage Tip: Store the frosted cake in an airtight container in the refrigerator for up to 3 days. Allow slices to sit at room temperature for 20 minutes before serving to restore the frosting's silkiness.Technique Tip: Avoid over-beating the mascarpone cheese, as it can break and turn grainy. Stop mixing as soon as the frosting is thick enough to hold its shape.Temperature Tip: Use room temperature eggs and milk to ensure the olive oil emulsifies properly for a glossy, unified batter.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
