Thread seems to have stalled and yes it is spelled wrong.

Makes One 2-pound loaf
• 3 tablespoons unsalted butter, melted, plus more for the pan
• 3 large, ripe bananas
• 1 large egg, lightly beaten
• 3/4 cups sugar
• 2 cups all-purpose flour
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 1/2 teaspoon kosher salt
1. Heat the oven to 350 degrees F, and butter a 5-by-9-inch loaf pan.
2. Peel the bananas and in a large mixing bowl, mash them well with a fork. Stir in the sugar and then the egg, mixing thoroughly. Stir in the butter.
3. Sift together the flour, baking soda, baking powder and salt. Fold the dry ingredients gently into the wet, mixing just until you no longer see any streaks of raw flour. (Do not over-mix, or the banana bread will be tough!)
4. Pour the batter into the prepared pan and bake for 45 to 55 minutes, until a toothpick inserted into the middle of the loaf comes out clean and the bread is just starting to come away from the sides of the pan.
5. Cool in the pan on a rack for 5 minutes, and then turn out onto the rack to cool completely before slicing and serving.
