Preheat your oven to 350°F. Begin by greasing a 10-inch cast iron skillet or another oven-safe pan.
In a large mixing bowl, cream the softened butter and sugar together until the mixture looks crumbly.
Add the egg, mashed bananas, and vanilla extract to the bowl. Mix until combined—don’t worry about small banana lumps.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually blend these dry ingredients into the wet mixture until just combined. Avoid overmixing to keep the bread tender.
Stir in 1/2 cup of the chocolate chips, ensuring they’re evenly distributed throughout the batter.
Pour the batter into your greased skillet, spreading it out evenly. Sprinkle the remaining chocolate chips and, if desired, some dried banana chips on top for extra texture and flavor.
Place the skillet in the oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the banana bread to cool in the skillet on a wire rack before slicing. Enjoy warm or at room temperature!
