Preheat your oven to 350°F (175°C). This ensures that the muffins bake evenly and rise properly.

Grease a muffin tin or line it with muffin liners to prevent sticking.

In a large mixing bowl, whisk together the flour, baking soda, baking powder, and salt. This helps to evenly distribute the leavening agents throughout the flour.

In another bowl, mash the ripe bananas until smooth. You can use a fork or a potato masher.

Add the granulated sugar, brown sugar, melted butter, eggs, and vanilla extract to the mashed bananas. Whisk until well combined and smooth.

Pour the wet ingredients into the dry ingredients. Gently fold them together using a rubber spatula until just combined. Be careful not to overmix, as this can make the muffins tough.

Fold in the chocolate chips until evenly distributed throughout the batter.

Spoon the batter into the prepared muffin tin, filling each cup about ⅔ full.

Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

Remove the muffins from the oven and let them cool in the pan for about 5 minutes before transferring them to a cooling rack to cool completely.

Enjoy your banana muffins warm or at room temperature!
