Creating Warm Snickerdoodle Cobbler is a breeze when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare Baking Dish: Grease a 9×13-inch baking dish with cooking spray or butter.
3. Mix Dry Ingredients: In a large bowl, combine the flour, sugar, baking soda, baking powder, ground cinnamon, and salt, mixing well.
4. Mix Wet Ingredients: In another bowl, whisk together the melted butter, egg, vanilla extract, and milk until smooth and well combined.
5. Combining Mixtures: Gradually add the wet mixture to the dry ingredients, stirring until just combined. Do not overmix.
6. Pour Batter: Pour the batter evenly into the prepared baking dish, smoothing the top.
7. Prepare Topping: In a small bowl, mix the additional sugar and cinnamon. Sprinkle this mixture evenly over the top of the batter.
8. Bake: Place the baking dish in the preheated oven and bake for 40-45 minutes or until the cobbler is golden brown and a toothpick inserted into the center comes out clean.
9. Cool Down: Once baked, remove from the oven and allow it to cool for about 10-15 minutes. This step allows the dessert to set slightly.
10. Serve Warm: The cobbler is best served warm for the ultimate experience.
