This moist Lemon Mascarpone Cake is tender, light, and full of bright lemon flavor. Using mascarpone in both the batter and the frosting creates a luxuriously creamy texture that keeps the crumb delicate and soft. It’s a lovely layer cake for celebrations or a sunny weekend dessert.

What is Mascarpone?
Mascarpone is a rich Italian cream cheese made by thickening fresh cream with a mild acid. It adds smooth richness and a velvety mouthfeel without overpowering the lemon notes, which is why it works so well in this cake recipe.
The Difference between Cream Cheese and Mascarpone
Although mascarpone is sometimes called Italian cream cheese, it has a higher fat content and a softer, silkier texture than regular cream cheese. It’s slightly sweeter and less tangy, which yields a more delicate frosting and a richer cake crumb. If you prefer a tangier finish you can substitute cream cheese, but mascarpone gives the cake its signature velvety character.

How to Make a Lemon Mascarpone Cake
The full, printable recipe appears below; here’s a concise overview of the method so you can see the flow of steps.
- Preheat the oven to 325°F (163°C). Grease and flour three 8-inch cake pans and line the bottoms with parchment rounds if desired.
- Whisk dry ingredients: In a medium bowl combine cake flour, baking powder, baking soda, and salt; whisk and set aside.
- Make the lemon-milk mixture: In another bowl mix milk, vegetable oil, lemon juice, lemon extract, and lemon zest. The mixture may look slightly curdled as the lemon reacts with the milk—this is fine.
- Cream butter and mascarpone: In a mixer bowl beat softened butter and mascarpone at medium speed until smooth. Gradually add granulated sugar and beat 2–3 minutes until light.
- Add eggs: Add room-temperature eggs one at a time, mixing until each is incorporated.
- Alternate dry and wet: On low speed, add the flour mixture and the milk mixture alternately, beginning and ending with the flour. Mix only until combined to avoid overworking the batter.
- Bake: Divide batter between the prepared pans and bake at 325°F for 28–30 minutes, or until a toothpick inserted in the center comes out clean or with a few crumbs. Cool in pans 5–10 minutes, then turn out onto a rack to cool completely.


Filling for the Cake
We use a simple lemon whipped cream for the filling. Chill the mixing bowl and whisk for about 10 minutes, then whip heavy cream with powdered sugar and lemon extract to stiff peaks. If desired, fold in fresh lemon zest for extra brightness.

Alternative Fillings
Lemon curd is an excellent option for an assertive lemon layer; layer it with whipped cream to balance the texture. You can also use the mascarpone frosting as a filling. For a less perishable option, a lemon buttercream will hold up better at room temperature.
Lemon Mascarpone Frosting
The mascarpone frosting is silky, slightly softer than traditional buttercream, and tastes similar to a cream cheese frosting but richer. Beat softened butter until smooth, add softened mascarpone, powdered sugar, and lemon extract, and mix until fluffy. If the frosting becomes too soft while working, chill briefly in the refrigerator to firm it up.

Assembling and Decorating
- Place the first layer on a cake plate and pipe a frosting dam around the edge.
- Spread the lemon whipped cream into the dam, then add the second layer and repeat. Top with the third layer.
- Fill gaps with frosting and apply a thin crumb coat. Chill the cake briefly (15 minutes in the freezer or longer in the fridge) to set the layers before applying the final coat.
- If the frosting gets too soft while decorating, chill the bowl, piping bag, or the assembled cake for a few minutes.
- After the final coat, smooth the sides, pipe decorations if desired, and garnish with thin lemon slices or zest.

Refrigerating and Serving Details
Because the filling is whipped cream and the frosting contains mascarpone, the cake should be refrigerated. For best flavor and texture, remove the cake from the refrigerator 2–3 hours before serving so it can come to a pleasant serving temperature.

Freezing Cake Layers
The cake layers freeze very well for up to three months and often seem moister after freezing. Turn cooled layers out onto foil-wrapped cardboard rounds, wrap while slightly warm with plastic wrap and then foil, and freeze. When ready to use, thaw wrapped on the counter until condensation forms on the foil—about 30–45 minutes—then unwrap and finish thawing before assembling. Many bakers prefer assembling while the layers are partially frozen since they’re easier to handle.
