If you're looking for quick, easy and delicious dessert recipes, you won't believe how good this frozen berry cobbler is! It's also really easy to make like dump cake. It's made with just a few ingredients including mixed frozen berries, boxed yellow cake mix, butter, walnuts and oats. Serve warm with vanilla ice cream. Oh my goodness!! My family loves this dessert recipe. It's great for any time of the year but we make it for special occassions like birthdays and family gatherings.
