Why You’ll Love Lemon Mascarpone Layer Cake Recipe
I love how this cake combines several layers of lemon flavor without becoming overpowering. The homemade lemon curd adds a refreshing tang, while the moist lemon cake provides a tender crumb. The whipped mascarpone frosting is smooth, airy, and less sweet than traditional buttercream, making it the perfect complement to the citrus notes. I also appreciate that this cake looks impressive enough for celebrations while remaining surprisingly simple to assemble.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.)
Lemon Curd
1/4 cup (60ml) fresh lemon juice (about 1–2 lemons)
2 tsp finely grated lemon zest
1/3 cup (69g) sugar
4 egg yolks
3 tbsp (42g) salted butter
Lemon Cake Layers
2 1/2 cups (325g) all purpose flour
1 3/4 tsp baking powder
1/4 tsp baking soda
1/2 tsp salt
1/2 cup (112g) unsalted butter, room temperature
1/2 cup (120ml) vegetable oil
1 1/2 cups (310g) sugar
1/2 tsp vanilla extract
4 large eggs
3/4 cup (180ml) milk
1/2 cup (120ml) fresh lemon juice
2 tbsp fresh lemon zest
Whipped Mascarpone Frosting
2 1/2 cups (600ml) heavy whipping cream, cold
1 1/2 cups (173g) powdered sugar
2 tsp vanilla extract
16 oz (452g) mascarpone cheese, chilled
Directions
I begin by making the lemon curd. I combine the lemon juice, lemon zest, sugar, egg yolks, and salted butter in a double boiler.
I whisk constantly while heating until the mixture thickens and coats the back of a spoon.
I transfer the curd to a heatproof bowl, press plastic wrap directly onto the surface, and refrigerate until completely chilled.
To prepare the cake layers, I preheat the oven to 350°F and prepare three 8-inch cake pans with parchment paper and grease.
In a bowl, I whisk together the flour, baking powder, baking soda, and salt.
In a large mixing bowl, I beat the butter, oil, sugar, and vanilla extract until light and fluffy.
I add the eggs one at a time, mixing well after each addition.
I mix in half of the dry ingredients until mostly combined.
In a separate container, I combine the milk and lemon juice.
I slowly add the milk mixture to the batter and mix until smooth.
I add the remaining dry ingredients and mix just until incorporated.
I gently fold in the lemon zest.
I divide the batter evenly among the prepared cake pans.
I bake the cakes for 22 to 25 minutes or until a toothpick inserted into the center comes out with a few moist crumbs.
I cool the cakes in their pans briefly before transferring them to wire racks to cool completely.
For the frosting, I whip the heavy cream, powdered sugar, and vanilla extract until soft peaks form.
I add the chilled mascarpone cheese and continue whipping until stiff peaks form.
To assemble, I level the cake layers if necessary.
I place the first cake layer on a serving plate and pipe a frosting border around the edge.
I spread half of the lemon curd inside the frosting border.
I add a layer of mascarpone frosting over the lemon curd.
I repeat the process with the second cake layer.
I place the final cake layer on top and frost the outside of the cake.
I decorate the cake as desired and refrigerate until ready to serve.
I prefer serving the cake slightly chilled for the best texture and flavor.
Servings and Timing
Yield: 12–14 slices
Prep Time: 2 hours
Cook Time: 35 minutes
Total Time: 2 hours 35 minutes
Variations
I sometimes add fresh berries between the cake layers for extra color and flavor. When I want a stronger citrus profile, I mix additional lemon zest into the frosting. For a more elegant presentation, I decorate the cake with candied lemon slices or edible flowers. I also enjoy using orange curd in place of lemon curd for a slightly different but equally delicious variation.
Storage/Reheating
I store this cake covered in the refrigerator for up to 4 days. Because the frosting contains mascarpone cheese and whipped cream, I keep it chilled until serving. If I need to prepare it ahead of time, I assemble the cake the day before and allow the flavors to develop overnight in the refrigerator. I do not recommend reheating this cake, as it is best enjoyed chilled or slightly cool.
FAQs

I often prepare the lemon curd a day or two in advance and store it in the refrigerator until I’m ready to assemble the cake.

How do I prevent the cake from becoming dense?

Can I decorate the cake in advance?
I usually decorate it several hours ahead of serving and keep it refrigerated until needed.
