Pour melted butter into a 8x8-inch casserole dish and swirl the pan gently to coat the bottom of the pan.
Whisk together milk, bisquick, and vanilla. Pour over the butter. Stir gently to distribute but don’t stir completely together.
In a large mixing bowl, stir together sugars, cinnamon, and nutmeg. Stir in the peaches until completely coated with the mixture. Spoon peaches evenly over the batter.
Bake 55-65 minutes, or until golden brown and set.
Let cool for at least 10-15 minutes, then serve warm or at room temperature, preferably with a scoop of vanilla ice cream!
Notes
Storing: Cover your cobbler with plastic wrap and/or foil to keep out moisture and store in the refrigerator for up to 3 days.
Freezing: Cobblers freeze quite well if properly stored. Wrap tightly with a couple layers of plastic wrap and foil, ideally right in the baking dish for easy reheating, then pop into the freezer. Thaw in the refrigerator overnight, then bring up to room temperature. You can also heat in oven for several minutes or until warmed through.
