50 g butter
2-3 spoons of cacao powder (I use instant, sweetened, but maybe natural would be even better)
1-2 spoons of sugar
180 g condensed (sweet) milk
2,5 packs of biscuits (those simple cheap ones, usually butter based)
(anything else you might want to add: nuts, coco, raisins, love...)
And then you just crumble the biscuits into small peaces (with your hands) in a big bowl
In a sauce pan you melt butter and all other ingredients until you get a smooth mass.
Once done you mix the mass with the biscuit crumbles (at first it seems that the mass is not enough, but don't worry, keep stirring).
And finally either find some form or just wrap it all in the aluminum foil (so it gets a shape) and put in the fridge for at least 2 h.
Voila fini:))
