Pro Tips

Use super ripe bananas—the riper they are, the sweeter and more flavorful your bread will be!
Toss the blueberries in a little flour before mixing them into the batter to keep them from sinking.
Don’t overmix! Stir the batter just until combined for the fluffiest texture.
Chill the crumb topping for 5 minutes before sprinkling it on for a better crumbly texture.
Let the bread cool before slicing so it holds together perfectly!
