Instructions
Preheat oven to 375 °F. Generously butter a 6 or 7-inch cast iron skillet (for a larger 9 or 10-inch skillet, simply double all the ingredients).
Combine flour, brown sugar, salt, and cinnamon in a large mixing bowl.
Cut butter into chunks and add to bowl with flour; work in with a couple of forks or cool hands (rubbing the pieces of butter in the flour to break them up) until flour is evenly moistened, and squeezing a bit of dough between your fingers will hold its shape. Add oats and mix until evenly incorporated, breaking into coarse crumbles. Refrigerate briefly while you prepare the filling.
In a bowl, toss peach wedges with bourbon. Sprinkle over sugar, cornstarch and salt and toss to coat. Dump into prepared skillet, smoothing and arranging peaches into an even layer. Sprinkle crumb mixture over top, breaking larger pieces into chickpea-sized crumbles. It's ok if it domes a little bit in the middle, the peaches will cook down in the oven.
Place skillet on a baking sheet (to catch any overflow). You may want to line it in foil too just in case.
Bake for 40 to 45 minutes (up to 55 minutes for a larger skillet) or until crumbles are golden brown and peach juices are bubbling up through the crumbles at the edges. Remove from oven and let cool for at least 20 minutes to allow the filling to thicken before serving. Serve with vanilla ice cream.
