I used full-fat ricotta and plain Greek yogurt (instead of sour cream) because that's what I had in the fridge. I like that you mix everything one bowl. It's a very rich batter (heavy on the eggs, cheese, yogurt; light on the flour). The resulting texture is kind of custard-y:
It's so good. I ate a slice and went back for another an hour later. This would be an easy and pretty summer dessert to bring to a potluck. I've read reviews that this works with just about any summer fruit- I'd like to try with peaches! Or a peaches/blueberry combo!
