Combine peaches, sugar, cornstarch, lemon juice, and cinnamon in the bowl and pour into the prepared pan.
In a separate bowl, combine cake mix and cinnamon and then sprinkle over the peach mixture.
Slice butter and place all over the top of the cake mix spacing evenly.
Bake for 40-45 minutes until golden and bubbly. Halfway through baking, rotate the pan and ensure that there are no dry spots. If there are, add a bit more butter to those spots.
