Butter the hell out of your pan. Give it a good dusting with some flour and shake it all around. Dump the excess flour. Set aside.
Cut pears in half and core. Slice thinly.
Put enough brown sugar to cover the bottom of the pan in entirety. I ran out of dark brown sugar, so I added some light. It didnt make a difference. Be generous with the sugar. I didnt measure. Maybe 1 1/2 cups unpacked. Sprinkle corn starch over the brown sugar. Better yet, use a small metal strainer (which I didnt use). Layer pear slices.
Prepare cake mix as directed and pour over pears.
Is used a cast iron pan and baked my cake at 325 F for 38 minutes. You may have to go to 350 F depending on what youre using for baking. Allow to cool about 20 minutes. Run a rubber spatula around the edges to loosen.
Find something suitably sized for flipping purposes. Flip that bad Larry and give it a rough shake like it owes you money if it doesnt drop right out. If it so happens that any of the surface is damaged, you can easily patch it with some brown sugar mixture on the bottom of the pan. Most chances are, you wont have to do much patching. Cut it like a pizza and serve.
