2 cups heavy cream
12 ounces mascarpone cheese
1/2 cup white sugar
1/4 cup limoncello liqueur
Zest of 3 Meyer lemons
1 teaspoon Meyer lemon juice
1 teaspoon vanilla
16-18 ounces lemon wafer cookies
Lemon zest curls for garnish
Using a standing mixer with a whisk attachment, combine the cream, mascarpone, sugar, limoncello, lemon zest, lemon juice and vanilla. Mix on low speed to begin, gradually increasing speed until firm peaks form.
Use an 8-inch springform pan to assemble the cake. You will be making 4 layers each of cookies and of filling.
Begin with a layer of cookies, overlapping to insure a solid base with no spaces between the cookies.
Next, add 1/4 of the filling and smooth with an offset spatula. Repeat the cookie-filling layers 3 more times, finishing with the cream filling on top of the cake.
Smooth carefully with a spatula. Cover and refrigerate overnight.
To serve, run a knife around the sides of the cake and remover sides of the springform pan. Using 2 spatulas, carefully lift the cake off the springform bottom. Place cake on a stand or plate. Garnish with lemon zest curls, cut and serve while still cold.
