Set your oven to 350 degrees Fahrenheit. Let it get nice and hot before you start. A hot oven helps the batter rise.

Put the stick of butter in your baking dish. Place the dish in the warming oven to melt. Watch it so the butter does not burn.

Whisk the flour and sugar in your mixing bowl. Slowly pour in the milk and the vanilla extract. Stir until the batter is very smooth and thick.

Take the baking dish out of the hot oven. Pour the batter right over the melted yellow butter. Do not stir the batter into the butter.

Open your cans of peaches with your can opener. Do not drain the syrup from the fruit cans. The syrup adds a lot of great flavor.

Gently spoon the peaches over the top of batter. Sprinkle a little bit of cinnamon over the fruit. Again, do not stir the layers together at all.

Slide the dish into the middle of the oven. Bake it for about thirty to forty-five minutes. The crust should rise to the top and brown.

Remove the cobbler when the top looks very golden. Let it sit for ten minutes before you scoop. This helps the juices thicken up a bit.
