To prepare filling: Combine peaches, 1/4 cup sugar, cornstarch, lemon zest, lemon juice and a pinch of salt in a large bowl; toss to coat. Transfer to a 9-inch shallow glass or ceramic baking dish.
To prepare topping: Whisk flour, cornmeal, baking powder, baking soda and salt in a large bowl until well blended. Whisk egg, buttermilk, oil and 2 tablespoons sugar in a small bowl. Add the wet ingredients to the dry ingredients and stir to blend.
Stir the remaining 1 tablespoon of sugar and cinnamon together in a small bowl and set aside.
Evenly spoon the batter over top of the peach mixture. Sprinkle the cinnamon sugar evenly over the topping. Place the baking dish on a baking sheet to catch any drips. Bake until the peaches are bubbly, the topping is golden brown and a toothpick inserted in the center of the topping comes out clean, 40 to 50 minutes. Let cool for about 20 minutes before serving.
