Preheat the oven to 375°F. Prep 2 small cast iron skillets with cooking spray or butter. Place on a lined baking sheet because things will get bubbly!
Mix the peaches, ginger, maple syrup and vanilla. Set aside.
Combine the oat flour, butter, brown sugar, salt and cinnamon. Using a fork or your hands, cut the butter into the oat mixture until it takes on a crumb-like appearance.
Heap half the peach mixture into each of the skillets. Top each with half the topping.
Bake about 30 minutes or until juices bubble and the topping becomes golden brown.
Let cool slightly. Serve warm with or without ice cream – your choice!
