Marshmallow and chocolate chip focacchia

I used https://alexandracooks.com/web-stories/the-best-and-easiest-overnight-focaccia/ as the base recipe. When I took the dough out of the fridge, I flattened it (using my fingertips) in a buttered 9×13" glass baking dish. I covered it in semisweet chocolate chips and marshmallows (large ones quartered). I folded it into 3rds length wise, then again width wise. I stuck it in my oven (slightly warmed since it was a cooler day). Once it had time to rise (about 3 hours) I drizzled with olive oil, sprinkled on a little kosher salt, and then some light brown sugar and proceeded to dimple it. I baked it woth my oven set to 450⁰F (no idea what the actual temp was because my oven is dying.. a thermometer doesn't help, because the temp fluctuates the entire time). About 18 minutes into the bake, I stuck more marshmallows on top, sticking them to the melted brown sugar. I baked until the marshmallows were toasty, but not burned. In the last couple of minutes in the oven, I sprinkled on more chocolate chips. I let it cool for about 30 minutes before cutting into it… it was sticky, sweet, gooey, and delicious!
