This easy no-bake strawberry rhubarb icebox cake features layers of ladyfingers, a creamy tiramisu filling and a homemade strawberry and rhubarb jam. The perfect "pick-me-up" sweet and tangy summer dessert. This all came about because the more rhubarb I pick the more it grows. A garden that keeps on giving.

Icebox Cake vs Tiramisu
An icebox cake is an old-fashioned dessert made famous by Nabisco and their crisp chocolate wafer cookies. The retro dessert features layers of cookies and sweetened whipped cream stacked together and chilled overnight to meld the two into soft cake-like layers.
Today, recipes like banana pudding with Nilla wafers and the trendy dot cakes are just variations of an icebox dessert. Tiramisu is another version. It's an Italian icebox cake featuring ladyfingers dipped in an espresso syrup and layered with a creamy mascarpone cheese filling.
I'd say my strawberry rhubarb icebox cake is a tiramisu strawberry rhubarb cake summer mash-up.

Ingredients You Will Need
- Fresh strawberries, rhubarb and lemon for the jam.
- Rhubarb and orange liqueur for the syrup.
- Crisp ladyfingers (a package of at least 24).
- Mascarpone cheese and heavy cream for the filling.
- 2 shortbread cookies and orange zest for the crumb topping.
- Pantry staples include sugar, cornstarch, eggs, vanilla.
