What you need: two cans of peach slices in heavy syrup, one stick of butter, one box of yellow cake mix, ground cinnamon, and a 9"x13" metal pan. Preheat your oven to 350F degrees.
Open and pour both cans of peaches and syrup into the baking pan. Then open and pour the yellow cake mix on top of the peaches. Press the cake down a bit.
Cut up the stick of butter and place the pieces of butter all over the top of the yellow cake mix.
Then sprinkle about 1/4 teaspoon of ground cinnamon over the top and put the pan in the oven for 30 minutes. Set the pan on a wire rack to cool for a bit.
Serve warm with a large spoon or spatula. Delicious and easy!
Store leftovers covered in the fridge.
