To tell you the truth I can't find it tasty even if I'm fond of mou cream.
This cake is something that, according to me, only children can love...
But for their parties it's so useful because it's quick and can be stored for a long time, it doesn't need spoons, plates or forks and it's totally junk :P
6 mars snacks
8 1/2 oz. rice crispies (white or chocolate ones)
3 1/2 butter
Divide mars in little pieces, put in a pan with butter and let it melt "bagnomaria".
When butter and melted mars will be well amalgamated add rice crispies and mix, keeping on low heat always "bagnomaria".
Take a baking tin (better if it's one with border that can be opened), pour the mix and press well with a spoon or even hands.
Let it get cold at room temperature, before serving take it out of the tin and cut with a long knife in slices or squares or brills.
If you want to decor the cake put on the bottom of the cake tin coloured chocolate coriandoli then pour the mixture: they will remain sticked to the cake.
P.S. : I rember this recipe from my childhood, especially in birthday parties but I never did it personally.
On the web the measures vary a lot so try this one than seems to me a good proportion then adjust the recipe following your taste (more mars, less butter or whatever).
