Ingredients
- 1/2 cup (1 stick) unsalted butter
- 2 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1 1/2 teaspoons Diamond Crystal Kosher Salt
- 1 cup packed light brown sugar
- ~2 cups mashed ripe bananas (from 4-5 bananas)
- 2 large eggs
- 1/2 cup full-fat Greek yogurt
- 1 teaspoon vanilla extract
Brown the Butter
First, melt the butter in a light-colored saucepan over medium heat. A light-colored pan lets you see the color change.
Keep swirling the pan as the butter melts. It will foam up, then the foam will subside.
Watch for brown specks to form at the bottom and for the butter to smell nutty. This happens quickly. As soon as you see this, pull it from the heat and pour it into a large bowl to cool.
Combine the Ingredients
Preheat your oven to 350F and grease a 9×5-inch loaf pan.
To the bowl with the cooled brown butter, add the packed light brown sugar and whisk to combine.
Add the mashed bananas, eggs, Greek yogurt, and vanilla extract. Whisk until everything is well combined.
In a separate, smaller bowl, whisk together the all-purpose flour, baking powder, and salt.
Add the dry ingredients to the wet ingredients. Use a rubber spatula to fold everything together until just combined. Don’t overmix; a few lumps are fine.
Bake the Bread
Pour the batter into the prepared loaf pan and smooth the top.
Bake for ~55-65 minutes. At the 55-minute mark, insert a toothpick into the center. If it comes out clean, it’s done. If not, give it another 5-10 minutes.
If the top starts to get too dark before the center is cooked, you can loosely tent it with aluminum foil.
Let It Cool Completely
Let the bread cool in the pan for at least 20 minutes before turning it out onto a wire rack.
It’s important to let it cool completely before slicing. The texture sets up as it cools. This bread is even better the next day.
