Hello dear M nostalgics

I remember that when I was young, about 20 years ago, you could buy muesli flakes (whether oat, wheat or rye flakes, I can't remember) from Quakers in Migros. They were very hard in consistency, lumpy, sweet in taste and had no fruit or anything like that in them, no chocolate chips, no raisins or anything like that.
Migros then removed the flakes from the range and shortly afterwards put its own very similar product on the shelves. I can't remember the name. The color of this packaging (of the new product) was dark reddish against light grape red. The size was very similar to the "M-Classic Crunchy Choco" product, for example. These new flakes were also very hard, sweetish and lumpy. These products were still on the shelves until about 4 years ago. Now they have also disappeared. They were my absolute favorite flakes and I always ate them with milk. The consistency remained quite hard even after 5 minutes in the milk. That's why I loved them so much!
Does anyone happen to know which flakes I mean, what they were called? Does anyone know an address/shop where these new (or the old original Quakers) can be obtained?

Best muesli greetings
