Limoncello Tiramisu in 25 Minutes - Creamy Citrus Mascarpone

Instructions:

1. In a shallow wide bowl, whisk together the limoncello liqueur, water, fresh lemon juice, and granulated sugar until the sugar is completely dissolved.
2. In a large mixing bowl, use an electric hand mixer to beat the chilled mascarpone, heavy whipping cream, powdered sugar, lemon curd, lemon zest, and vanilla paste on medium-high speed until stiff peaks form and the mixture is light and airy.
3. Quickly dip half of the ladyfingers into the limoncello soak for about 2 seconds per side. Arrange them in a single layer in the bottom of a 9x9 inch baking dish.
4. Spread half of the citrus mascarpone filling over the layer of ladyfingers using an offset spatula to create an even surface.
5. Repeat the dipping process with the remaining ladyfingers and create a second layer. Top with the remaining mascarpone mixture.
6. Cover the dish tightly and refrigerate for at least 6 hours (or overnight) to allow the ladyfingers to soften and the flavors to meld.
7. Before serving, garnish with white chocolate shavings and fresh mint leaves.
