Wash the peaches and cut them into small pieces. In a small bowl combine the honey, sriracha, and cinnamon. Pour over the peaches and toss to coat. Sprinkle the cornstarch over the peaches and toss to coat again.
In a separate bowl, combine the oats, flour, salt, and brown sugar. Stir until evenly mixed. Add the butter and mix it in until it forms a crumbly, sand-like mixture. I find it best to just get my hands in there and “squish” it all together.
Preheat the oven to 375 degrees. Place the seasoned peaches in the bottom of an 8×8 (or round) baking dish. Cover the peaches completely with the oat mixture. Bake in the preheated oven for about 30 minutes or until golden brown on top and the fruit is bubbling up. Serve hot or cold!
