Preheat the oven to 350 F. Prepare a 9X13 baking dish by pouring the melted butter into the pan and coating the bottom and sides. There will be extra butter in the pan. Leave it!

Put the canned peaches, including the juice, into a medium saucepan. Turn the heat to medium and add one cup of sugar and 1/2 cup of water. Bring the mixture to a simmer.

Once the peaches are simmering, stir the cornstarch into the remaining water. Pour the mixture into the saucepan and simmer for about three minutes until the sauce thickens. Remove the peaches from the heat and let them cool slightly while making the batter.

In a medium mixing bowl, whisk together the flour, vanilla, 1 1/2 cups of sugar, and milk.

Pour the peaches into the pan on top of the butter, do not mix. Spoon the flour mixture over the peaches. It may not cover the peaches completely, which is totally fine!

Add the cinnamon to the remaining sugar and dust it on the cobbler.

Bake for thirty minutes or until golden brown.
