Follow these straightforward steps to create your amazing 4 Ingredient Blueberry Cobbler:

1. Preheat Your Oven: Begin by preheating your oven to 350°F (175°C).

2. Prepare the Baking Dish: Grease a 9-inch square baking dish with butter or cooking spray to prevent sticking.

3. Mix the Blueberries: In a bowl, combine the blueberries and ½ cup of sugar. Let them sit for about 10 minutes as they release their juices.

4. Make the Batter: In a separate bowl, mix together the remaining ½ cup of sugar, self-rising flour, and milk until you have a smooth batter.

5. Combine: Pour the batter into the greased baking dish. Do not stir; simply allow it to settle at the bottom.

6. Add the Blueberries: Spoon the blueberry mixture over the batter, ensuring even distribution.

7. Bake: Place the dish in the preheated oven and bake for 30-35 minutes or until the top is golden brown and a toothpick comes out clean.

8. Cool: Once baked, remove from the oven and let it cool for about 10 minutes before serving.

Your delightful cobbler is now ready to be enjoyed!
