First, prepare the peaches. Preheat the oven to 425. Combine the sliced peaches, sugar, cinnamon, bourbon, and corn starch in a large bowl and stir it all together well to make sure the peaches are coated completely. Transfer the mixture to an 8 x 8 baking dish and bake the peaches for 10 minutes. Meanwhile, work on the topping. Combine the flour, brown sugar, baking powder and butter in a bowl. Use a pastry blender to cut the butter into the rest of the mixture until it is moist and crumbly.

Heat the water in a small sauce pan and let it come to a gentle boil over medium heat. Stir in the rest of the topping mixture until it makes a pasty dough and take it off of the heat. Evenly crumble the topping over the peaches. Then stir the sugar and cinnamon together in a small bowl and sprinkle that evenly on the very top. Bake the cobbler for about 30 minutes, until the top is crispy. Let it cool and set for a couple of minutes, then serve warm with ice cream!
