Blend the oats in a blender. Peel the apples, clean them of their seeds and grate them coarsely. Mash the bananas. Chop the dried fruits into medium-sized pieces. You can put raisins/cranberries in whole.
Mix all the ingredients for the cake layer well. If the mixture is too runny, add a few more oats or dried fruits. The texture needs to be soft but dense.
Prepare a cake form (about 9 1/2″ (24 cm)) with removable walls, lay it out with baking paper. Distribute the cake layer in it, shape a border around the edges. Put it in the fridge.
Put the gelatin in a little water and leave it to swell. Make it as described on the package.
Boil the carrots in 4 1/5 cups (1 L) water until the water is fully absorbed. Mash them, add the starch, butter, sugar and nutmeg - mash once again. Add the gelatin and stir.
Pour the cream over the cake layer and return to the fridge. Leave it to harden overnight. Optionally, you can decorate with ground nuts of your choice or finely chopped dried fruits.
Note: If you'd like a stiffer cream, you can use 2 gelatins.
