I substituted the sour cream for greek yogurt, but they turned out too doughy and only moist with a mouthful of berries.. Not my favourite recipe.
Very moist and not too sweet. I used a combo of blueberries, blackberries, raspberries and strawberries and a mixed berry yougurt. They were great and the fact that they are healthy is even better! I cooked mine for 23 minutes and they were perfect. Made for PAC Fall 2011.
