Prepare the Equipment: Lightly grease a 10-inch heavy-bottomed pot. Alternatively, line with parchment paper, leaving an overhang for easy removal.
Combine Wet Ingredients: In a mixing bowl, combine mashed bananas, melted butter, sugar, egg, and vanilla extract. Mix until well blended.
Incorporate Dry Ingredients: In a separate bowl, whisk together flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing.
Add Nuts (Optional): Fold in chopped nuts, if desired.
Transfer to Pot: Pour the batter into the prepared pot, spreading evenly.
Prepare for Baking: Cover the pot with its lid. Arrange hot coals on top of the lid and underneath the pot, maintaining a moderate, even heat. Alternatively, place on a grill over indirect heat.
Bake: Bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean. Check for doneness after 45 minutes, adjusting coal placement to prevent burning if necessary.
Cool and Serve: Remove the pot from the heat and let the bread cool slightly before lifting it out using the parchment paper overhang (if used). Slice and serve warm or at room temperature.
Tips: For a richer flavor, use brown butter instead of melted butter. Spices like cinnamon or nutmeg can be added to the dry ingredients for enhanced flavor. To prevent the bread from sticking, ensure the heavy-bottomed pot is well-greased or lined with parchment paper. If the top begins to brown too quickly, reduce the heat by removing some of the coals from the lid.
