I present my Italian Lemon Mascarpone Tart, blending creamy mascarpone with a bright zing of lemon zest and juice within a sour cream-based, buttery short crust. I included all-purpose flour, powdered sugar and cold unsalted butter for the crust while three eggs perfectly bind the tangy, irresistibly rich filling exquisitely.

I recently discovered an incredible Italian Lemon And Mascarpone Tart that is surprisingly easy to put together. The recipe is creamy, tangy, and loaded with that bright lemon punch that I totally love.
The secret behind it is the food processor technique; both the filling and the sour cream short crust pastry come together in no time. For the crust I mix 1 1/2 cups of all-purpose flour with 1/4 cup powdered sugar, a pinch of salt, 1/2 cup cold unsalted butter, and 3 tablespoons of sour cream.
The filling is where things get interesting; I blend 8 oz of mascarpone cheese with 3 large eggs, 3/4 cup granulated sugar, the zest from 2 lemons, 1/3 cup fresh lemon juice and an extra touch of sour cream. This tart is not only a twist on the traditional lemon cheesecake tart, it feels like a creative upgrade on a classic lemon dessert.
Enjoy every bite!
Why I Like this Recipe
1. I really love the balance between the tangy lemon flavor and the creamy mascarpone filling. It feels so refreshing and unique compared to other desserts I make.
2. I like that it’s super simple to put together cause both the crust and the filling come together in the food processor, which means less mess and less stress.
3. The sour cream short crust is my favorite part because it’s flaky and melts in your mouth, making every bite feel like a little treat.
4. I enjoy how versatile it is too – whether I serve it slightly chilled or at room temperature, it always tastes just right and brings a bit of sunshine to my day.

FAQ
Italian Lemon And Mascarpone Tart Recipe Substitutions and Variations
- For the crust’s all-purpose flour, you can swap it for pastry flour or try mixing half whole wheat flour with half all-purpose for a nuttier flavor.
- If you don’t have sour cream on hand, plain full-fat Greek yogurt works pretty well as a replacement in both the crust and filling.
- Instead of cold unsalted butter, you can use salted butter, but remember to cut back a little on the added salt in the recipe.
- For mascarpone cheese in the filling, try blending cream cheese with a bit (about 1-2 tablespoons) of heavy cream to get a similar creamy texture.
- If you’re out of granulated sugar, consider using coconut sugar. Just be aware that it might change the flavor and color slightly.
Pro Tips
1. When making the crust make sure your butter and sour cream are super cold. It really helps create a flaky, tender base and stops the butter from melting too fast when you mix it with the flour.
2. Try not to overprocess or overwork the dough in your food processor. If you blend it too much, you’ll end up with a greasy dough instead of that nice crumbly texture you want.
3. Let the crust cool a little bit after its initial 10-minute bake before putting on the filling. Giving it a few minutes helps it firm up better so it doesn’t get soggy once the creamy lemon topping is added.
4. When blending the mascarpone filling, make sure to scrape down the sides of the food processor. This way you’ll get every bit of mix smooth and consistent, keeping nasty lumps out of your tart.
