Brown Butter Banana Bread Recipe

Brown Butter Banana Bread

This isn't your average banana bread. Browning the butter is the key step that adds a deep, nutty flavor, and a mix of flours gives it a more complex character without being heavy. The final texture is incredibly moist, almost custardy.

Notes

Flavor improves next day.
Do not overmix batter - some lumps are good.
