The muffins turned out amazing, they were moist and sweet! On the other hand frosting was way too sweet, even tho I added only 220 gr of confectioners sugar. Next time i would add even less! I also added 2 tbsp of heavy cream to the frosting so it would be fluffier. I used store bought caramel, so i cant comment anything about that. At the end they turned out okay, not sure if i would make them again.:/
