This is the perfect recipe for kids to help with. Take them to a Farmers' Market to pick out some fresh peaches and then get cooking!
Preheat oven to 425 F.
Toss thinly sliced peaches with sugar, lemon juice and cornstarch in a 2 qt, non reactive baking dish in the middle of the oven for 10 minutes.
You can make the topping while the peaches bake.
Blend in small pieces of butter with your fingertips until mixture resembles coarse meal.
Stir in water just until combined.
Remove peaches from the oven and drop spoonfuls of the topping over them. Bake in the middle of the oven until topping is golden brown, about 15-20 minutes. Topping will spread as it bakes.
Serve warm all on its own or dress it up with a dollop of vanilla ice cream or whipped cream. The perfect dessert for a warm summer night.
