This old fashioned Peach Cobbler with sourdough biscuits on top is the best peach cobbler you will ever make! The sourdough biscuit topping needs to be prepared a day in advanced, but it is so worth the extra wait. There are no shortcuts in this fantastic recipe. We use fresh peaches and a from-scratch sourdough biscuit topping. It is absolutely delicious and best served warm with vanilla ice cream on top.
