You could describe an icebox cake as being somewhere between a trifle and a cheesecake. This easy to make, no bake recipe uses Lady Fingers or sponge fingers, lightly dipped in lemon and Limoncello, which helps turn them into pillows of soft zingy sponge. If your store cupboard is lacking in Limoncello, simply replace with more lemon juice.
This easy to make Lemon Icebox cake, can be ready in a few hours. Layer upon layer of sponge fingers, with layer upon layer of mascarpone and cream filling.
The sponge fingers will gradually soften as the cream filling starts to set. Which makes it easier to slice. It'll keep in the fridge for a few days.
Why this recipes works.
- Use unwaxed lemons.
- Using a mix of Mascarpone and cream gives a really nice thick consistency for the filling.
- Using natural Lemon flavouring enhances the flavours from the Lemons and Limoncello.
- A square tin makes it easier to layer the sponge fingers. And also makes it easier to slice evenly.
How to remove the wax from waxed lemons.
- To clean the wax from lemons, place them in a sieve or colander and carefully pour boiling water over the lemons. Scrub the lemons with a vegetable brush to remove the wax. Pat dry before using. You can clean other waxed citrus fruits the same way.
