Preheat oven to a medium broil with shelf placed two levels below broiler.
Only half of the store bought pizza dough is needed to make two servings. Cut it in half and store the other half to make again later.
Cut the pizza dough in half and roll it out on a floured surface into two 1/4” pieces.
In a large cast iron pan, melt the butter and add the oil over medium high heat.
Once the butter and oil are hot, add the rolled out pizza dough. Once lightly browned on the first side, turn the heat down to low and flip.
Sprinkle very generously with powdered sugar and very lightly with cinnamon while browning the other side.
Flip again once the other side is lightly browned, remove from heat and again sprinkle very generously with powdered sugar and very lightly with cinnamon.
Top both generously with chocolate chips and place the cast iron pan into the oven for a couple minutes to allow the chocolate to get soft. Don’t do this for too long or the chocolate chips may burn.
After two minutes top with the mini marshmallows (be careful not to touch the chocolate with your fingers - you will get burned!). Watch closely until the marshmallows become lightly browned and remove from oven.
Sprinkle generously with powdered sugar.
Let cool for two minutes on individual plates - serve - and enjoy!
