Try and upside down cake in a cast iron skillet. Here's one idea.....
Boil one bag of fresh cranberries for 3 minutes. Add one can of cranberry sauce to the fresh berries and let stand to cool.
Preheat oven to 350. Place cast iron skillet in oven and melt 2 tlbs of butter. Lightly sprinkle granulated sugar over melted butter.
Cover bottom of skillet with 1/2 of berry mixture. Prepare box cake mix according to package instructions. Pour 1/2 of cake batter over berries. Bake for 30 minutes at 350 degrees.
Immediately invert cake onto plate by placing plate overtop the skillet while turning the plate and skillet upside down. Do this in a smooth motion to prevent cake from sliding off plate.
There will be sufficient berries and batter to make 2 cakes.
