1-First Step: Prepare the Mise en Place Start by selecting 3 ripe bananas, ideally with black peels for peak sweetness. Peel and mash them in a large bowl using a fork until smooth, measuring about 1 1/2 cups. This releases their juices, key for moisture. Melt 1/3 cup butter in the microwave or stovetop, then stir into the bananas. Add 1 cup sugar (brown for richer taste), 1 beaten egg, and 1 tsp vanilla extract. Mix until combined, about 1 minute. Room-temperature items prevent lumps.

2-Second Step: Combine Dry Ingredients In a separate bowl, whisk 1 1/2 cups flour, 1 tsp baking soda, and a pinch of salt. This ensures even distribution and proper rise. Avoid packing flour; spoon and level for accuracy. Sifting helps if your flour clumps. These dry goods react with banana acids for lift without toughness.

3-Third Step: Mix Wet and Dry Gently fold dry mixture into wet using a spatula. Stir just until no flour streaks remain, 30-45 seconds. Overmixing develops gluten, leading to dense bread. Batter should look lumpy, thick, and ribbon off the spoon. Let rest 5 minutes if time allows; baking soda activates fully.

4-Fourth Step: Pour and Bake Scrape batter into prepared pan, smoothing the top. Tap pan on counter to release air bubbles. Bake at 350°F (175°C) for 60-65 minutes. Check at 55 minutes; toothpick inserted in center should emerge clean or with moist crumbs. Tent with foil after 40 minutes if browning fast. Rotate pan halfway for even cooking. Ovens vary, so use an oven thermometer for precision.

5-Fifth Step: Cool Properly Cool in pan 10 minutes on a wire rack. Loosen edges with a knife, then invert onto rack. Cool fully, 1-2 hours, before slicing. This prevents gumminess. Warm slices taste best, but patience pays off.
