We lightened up this cobbler by using reduced-fat sour cream and far less butter than most traditional recipes. It's moist and delicious, bursting with warm fresh raspberries and juicy peaches. It's a rustic, hearty, satisfying dessert that hits all the right flavor notes. You'll love making it to feed a crowd for an after-dinner treat, or you may even find yourself reaching for a bowl at breakfast as a sweet pick-me-up in the morning—we won't judge you. You can also feel free to substitute thawed, frozen fruit for the fresh fruit, if desired. Substitute nectarines or apricots for the peaches, and blueberries or blackberries for the raspberries.
