# Expert Tips:

01 -
  • The texture is incredibly moist without being dense or heavy
  • They freeze beautifully so you can bake once and eat for weeks
02 -
  • Over mixing is the enemy of fluffy muffins, stop as soon as flour disappears
  • Letting them cool in the pan for those 5 minutes prevents them from falling apart
03 -
  • Use really ripe bananas with lots of brown spots for the sweetest flavor
  • Room temperature ingredients blend more easily and create better texture
