| Granulated Sugar | 1/2 cup (100g) | Sweetness and structure. |

| Egg | 1 large, room temperature | Binding and lift. |
| Vanilla Extract | 1 tsp | Flavor enhancement. |

Optional Mix-ins (1/2 cup): Semi-sweet chocolate chips, chopped walnuts, or toasted pecans.
2. Essential Kitchen Tools
- 8.5 x 4.5-inch loaf pan
- Large mixing bowl
- Medium mixing bowl
- Fork or potato masher (for bananas)
- Whisk and silicone spatula
- Kitchen scale (for precise measurements)
- Toothpick or cake tester
3. Step-by-Step Baking Workflow
Step 1: Prep
- Preheat your oven to 350°F (175°C).
- Grease the loaf pan with butter or non-stick spray, and line it with parchment paper leaving an overhang for easy removal.
Step 2: Wet Ingredients
- In a large bowl, mash the bananas thoroughly until smooth.
- Whisk in the melted butter until completely incorporated.
- Whisk in the sugars, egg, and vanilla extract until well combined and smooth.
Step 3: Dry Ingredients
- In a separate bowl, whisk together the flour, baking soda, and salt.
- Gently fold the dry ingredients into the wet banana mixture using a spatula. Stop mixing just as the flour disappears to prevent gluten development (which leads to a tough texture).
- If using mix-ins, gently fold them in now.
Step 4: Bake
- Pour the batter into the prepared loaf pan and smooth the top.
- Bake for 50 to 60 minutes.
- At the 45-minute mark, insert a toothpick into the center. It should come out clean or with a few moist crumbs.
- If the top is browning too quickly, tent the pan loosely with aluminum foil.
Step 5: Cool
- Let the banana bread cool in the pan for 10 minutes.
- Lift it out using the parchment overhang and place it on a wire rack to cool completely before slicing.
