Melt the chocolate in a double boiler. Mix all ingredients well. Place on a parchment-lined baking sheet.
Bake in a preheated oven at 120 ° C (top / bottom heat) for about 40 minutes. Stir once. I turn on the grill setting for the last few minutes - it gives off a delicious roasted aroma. But you have to stop next to it - the muesli burns very quickly.
Let cool down well, the muesli will be nice and crispy.
