Banana Bread with Browned Butter is a classic-style loaf with a deeper, richer flavor thanks to the nutty butter base. It's a dependable bake that works just as well for breakfast as it does for an afternoon snack.
Preheat oven to 350°F. Grease a 9x5-inch loaf pan or line with parchment paper.
In a small saucepan, melt the butter over medium heat. Continue cooking, stirring often, until golden brown with a nutty aroma (about 4–5 minutes). Remove from heat and let cool slightly.
In a large bowl, whisk together the mashed bananas, brown sugar, eggs, and vanilla. Slowly whisk in the browned butter.
In a separate bowl, mix the flour, baking soda, salt, and cinnamon (if using). Add to the wet ingredients and stir just until combined.
Pour batter into the prepared loaf pan and smooth the top.
Bake for 55 minutes or until a toothpick inserted in the center comes out clean.
Cool in the pan for 10 minutes, then transfer loaf to a wire rack to cool completely.
