You are currently viewing Jelly Cake with Watermelon and Cherries

A low sugar jelly cake with watermelon, cherries and berries. This recipe is a real treat during summertime. It’s light, fruity and very creamy. Basically, everything that screams an amazing dessert. If you haven’t made a jelly cake before, now’s the time to do it.

Berries are the ultimate ingredient during the summer months. They are fragrant, sweet and full of flavour. It’s no surprise, but making desserts with these summer-goodies is the best thing you can do during this short period of time.

Back in Lithuania, jelly cakes are very popular during celebrations… and the more layers you add, the more impressive cake you’ll end up with. I took this idea and incorporated it into this summer jelly cake with mascarpone, cherries and watermelon layers.

Now I’m not going to lie, this jelly cake isn’t the quickest recipe. You’ll need some planning and preparation, and need to start at least 48 hours before serving. Unfortunately, there are no big shortcuts. You need properly chill each layer before adding a new one. But guys… this recipe is worth the effort, believe me! My Fussy Easter was quite sceptical about the cake, but the moment he tasted it, he was blown away by the flavours.

Another advantage of this cake is it’s very low in sugar. All the berries and fruits are in season, so they’re full of natural sugars with lots of sweetness. Due to this, there’s no need to add loads of additional sugar to this recipe.

How to Make Jelly Cake with Watermelon

This four layered jelly cake is a real summer celebration, but in order to nail this recipe, you’ll need to pay attention to each individual layer.

Here’s some advice on each…

Crust layer

Let me tell you a secret. I don’t use biscuits for my base. I use the leftover bits from baking tart cases. Every time I bake a tart, I keep the leftover cuts and store them. The moment I have a full jar of scraps – it’s time to bake a cheesecake.

So, for this recipe, I used my lovely tart leftovers, blitzed them in a food processor with melted butter and added the base to a cake case. Simple!

Cheese layer

This layer is like making a silky and creamy panna cotta (I took inspiration from this recipe). Mix all the ingredients, dissolve the gelatine sheets and pour the mixture on top of the crust layer.

Cherry and strawberry layer

Similarly to the cheese layer, you’ll need to heat and mix all the ingredients. After that, blitz the mixture in a food blender and pour it through a sieve to get a silky texture. Add the soaked gelatine sheets and heat with the berry mixture to dissolve them.

Watermelon layer

Make the watermelon juice – cut the fruit, blitz in a food blender, pour the flesh through a sieve and remove all the seeds and pulps.

Heat the juice, add the gelatine sheets, dissolve them and pour the mixture on top of the cherry layer (just be sure the previous layer is completely set first!).
