Strain the juice from one can of peaches. Pour the peaches from the first can into the baking dish. Open and pour the other two cans of sliced peaches with all the syrup into the baking dish.
Mix in the ground cinnamon, cornstarch and 2 tablespoons (25 g) of light brown sugar into the sliced peaches until well combined. Make sure all the peaches are coated.
Bake the peach cobbler for 30 - 40 minutes or until the top is a beautiful golden brown and the peach filling is bubbling around the edges of the baking dish.
Cool the peach cobbler for 30 minutes. Once the cobbler has cooled a bit, scoop out the warm peach cobbler onto a plate or shallow bowl. Top with cold vanilla ice cream or freshly whipped cream and enjoy!
