A vibrant, no-bake twist on the Italian classic, Limoncello Tiramisu features layers of soft ladyfingers soaked in citrus syrup, a creamy lemon mascarpone filling, and bright, fresh flavor in every chilled bite. It’s light, cheerful, and perfect for spring or summer celebrations.
Make syrup: Simmer limoncello syrup, lemon juice, 2 Tbsp sugar, and lemon zest until sugar dissolves. Let cool.
Prepare custard: Whisk yolks with sugar over simmering water until thick and pale. Cool slightly.
Make filling: Mix mascarpone with lemon curd and vanilla. Fold in custard.
Whip cream: Beat cream to soft peaks and gently fold into the mascarpone mixture.
Assemble layers: Quickly dip ladyfingers in cooled syrup (2 seconds per side). Layer half in the dish, top with half the filling, and add optional blueberries.
Repeat: Add a second soaked-ladyfinger layer and remaining filling. Smooth the top.
Chill: Cover and refrigerate at least 4 hours or overnight. Garnish with zest and white chocolate before serving.
Notes
This recipe uses pasteurized egg yolks for safety and is completely alcohol-free, making it family-friendly. Be sure to chill it long enough to let those lovely layers set.
