In a mixing bowl, combine the self-rising flour, sugar, milk, and ½ teaspoon cinnamon with a hand mixer until smooth and well combined.
Add the unsalted butter to a 19x26 cm (7.5x10 inch) pan and melt it in a preheated oven at 347°F(175°C) or 311°F(155°C) for fan-assisted.
Pour the batter over the melted butter and do not mix. Pour a few spoons of applesauce all over the batter and do not mix. Sprinkle ½ teaspoon cinnamon over the applesauce.
Bake in a preheated oven at 347°F(175°C) or 311°F(155°C) for fan-assisted, for 40-45 minutes, or until the top is golden brown and the cobbler is cooked through.
Let it cool slightly before serving. Enjoy warm, optionally with a scoop of ice cream or whipped cream!
Notes
Avoid Overmixing: I mix the batter just until it’s smooth; going too far can make it dense instead of light and tender.Batter Consistency: I like the batter to be pourable but not too thin. If it feels a bit heavy, I add a splash more milk to get that smooth consistency; it helps the cobbler bake up evenly.Do Not Stir After Pouring: Once the batter is poured, I leave it alone. Mixing it with the butter or applesauce stops it from forming that soft, cakey top that soaks in all the apple flavor.Check for Doneness: I start checking around the 40-minute mark. The top should be golden, and a toothpick should come out clean. If it needs more time, I will give it another 5–10 minutes.Allow Cooling Time: I always let the cobbler cool for a bit before serving. It helps it set and makes scooping much easier.
