Well, I had to give it a try, more so that I had the biscuits and muesli.
So, all you need:
- muesli, raisins (I used muesli with 40% fruit content),
- yogurt (three 400 g containers),
- powdered sugar (optional, but my husband won't eat it unsweetened),
- soft fruit (berries would be best, but these sweet soft and ripe pears did just fine).
Cover with fruit and muesli, spread yogurt.
Follows the next row of biscuits. I poured some jam too (the children had eaten the plums and only the jelly was left, so it was the perfect opportunity to get rid of this jar :)
Again spread the yogurt, arrange the fruit and muesli on top and leave it to rest in the fridge for at least a day.
