Return the pan to the oven and bake for 20-30 minutes, or until golden on top.
Let cool in pan for 10 minutes.
Notes
Butter: I use salted butter in both the filling and the topping. If using unsalted butter, add a pinch or two of salt to both the filling and the topping.
Peaches: I don't peel the peaches before using. The peaches should be ripe but not over-ripe and smooshy for this recipe.
Bourbon: The bourbon just adds a bit of extra flavor. Feel free to omit it or to use 1/2 teaspoon bourbon flavor instead.
Milk: Any milk from skim milk to whole milk will work in this recipe.
