Cobbler made from frozen fruit, cake mix, and a can of soda - my kind of food prep! 1. First spray your 9 x 13 pan with Pam. Then pour your berries into the pan. 2. Spread frozen berries out so that they are all evenly dispersed. 3. Add dry white cake mix over the top. 4. Pour a can of Sprite Zero soda slowly over cake mix. Do not stir 5. Bake 350 for 45-50 min.
