Creating this Irresistible Southern Banana Cobbler is a delightful process. Follow these steps carefully for the best results:

1. Preheat your oven to 350°F (175°C).
2. Prepare the Bananas: In a medium bowl, toss the sliced bananas with lemon juice, 1/2 cup of sugar, cinnamon, nutmeg, and cornstarch. Set aside to allow the flavors to meld.
3. Mix Dry Ingredients: In another bowl, whisk together the all-purpose flour, baking powder, salt, and remaining 1/2 cup of sugar.
4. Combine Wet Ingredients: In a separate small bowl, mix the melted butter, milk, and vanilla extract until well combined.
5. Combine Mixtures: Pour the wet ingredient mixture into the dry ingredients. Stir gently until just combined; do not overmix.
6. Layer the Bananas: Pour the banana mixture into a greased 9×13-inch baking dish. Spread it evenly.
7. Add the Batter: Carefully pour the batter over the banana mixture, allowing it to flow naturally over the top.
8. Bake: Place the dish in the preheated oven and bake for 45-50 minutes or until the top is golden brown and a toothpick inserted into the center comes out clean.
9. Cool: Remove the cobbler from the oven and allow it to cool for 10-15 minutes before serving.

This step-by-step process ensures that your cobbler turns out perfectly every time!
