Boil the water in a kettle.

To prepare gelatine, you need to pour hot water into a small pot (3/4 of amount stated in the gelatine's packaging instructions), then place the gelatine powder in the water and mix until it is dissolved.

Do the same with different coloured jellies. Two of them need to be made in a medium bowls and two in a rectangular or square shaped Tupperware container. The bowl ones stay in room temperature and the square ones need to be placed in the fridge to set quicker. Those jellies in plastic boxes will be used to cut the cubes out of the jelly.

Place chosen low FODMAP fruit in a large bowl or container, where you will be setting the whole "cake".

When the jelly cools down, quickly mix in all of the lactose free yogurt and add sweetener. Pour part of the white jelly mass on top of the fruit, if you want a white top of the cake later. Place it in the fridge.

When jellies for cubes are completely set in the fridge, you can continue creating your jelly cake. Cut the cubes in a jelly with a knife, doing it in a crossing pattern. Place some of cubes of different colours on top of previous layers; then you can pour some of the white yogurt jelly. If the yogurt jelly start to set in the pot, you can warm it up slightly over a water bath.

You can also add some more fruit, pour the liquid jelly from the bowls that will create thin layers, just remember to set it in the fridge after each layer or the colours of liquid jelly will mix.

In the end, of course, you need to place the stained glass jelly cake in the fridge for a few hours or until well set.

It is easier to serve the jelly cake straight from the bowl, using a large spoon to serve, but then you lack the great effect and it is messy.

The best is to place the bowl with the cake over a steaming larger pot with hot water, just for few seconds, so the edges of the jelly cake will lose up from the edges. Then place a nice serving plate on top, up side down and turn the cake over on this plate. You need to be quick so the jelly won't land on the floor!

Enjoy!
