Just to let you know, I made this cake and it is delicious! As I said in my other comment I used pears. I also did not use all the topping. I just put a thin layer using about half the mixture. The cake is so soft and tender. I'm sure any fruit would work here. I had a small slice, still quite warm, but then I just had to have another piece😂😋. Thank you!!

Quark is a type of fresh dairy product, popular in many European countries, especially Germany. It’s similar to yogurt or cream cheese but with a slightly tangy, mild flavor and a creamy texture. It’s very versatile-you can use it in baking, cooking, or enjoy it as a snack with fruits or honey. 😊 If you don’t have quark available, you can often substitute it with Greek yogurt or a mix of cream cheese and yogurt. ~ *_Anna_* 🌿💝 kitchen-by-nature.com/
