Baked for 40 min. in a 8x8 glass dish. This came out soooo good, no problems with raw center as others mentioned. This is the recipe I will use for peach cobbler from now on! So easy and quick and good! YUMMY!! Thanks so much! Read More Sprinkle dry cake mix evenly over top of peach mixture. Poke holes into cake mix to allow juice through. Cut stick of margarine into small pats, placing randomly over the top. Sprinkle with the remaining 1/2 cup of sugar and a light dusting of cinnamon.
