  • 0.5 cup butter melted
  • 0.75 cup sugar
  • 2 eggs large
  • 1 tsp vanilla extract
  • 1.5 cup all-purpose flour
  • 1 tsp baking soda
  • 0.5 tsp salt
  • 0.5 tsp cinnamon
Cinnamon crunch topping
  • 0.3333 cup brown sugar

  • 0.25 cup flour
  • 0.0625 tsp salt pinch

Equipment

  • 1 sheet pan

Method
 

Prep and topping
  1. Preheat oven to 350°F and grease a 9x5 loaf pan. Lightly coat all sides so the loaf releases cleanly.
  2. Mix brown sugar, cinnamon, melted butter, flour, and salt until crumbly, then set aside. The mixture should look like small clusters, not a paste.
Make the banana bread batter
  1. Whisk melted butter, sugar, eggs, and vanilla into mashed bananas until smooth. Stop once no banana streaks remain for a tender crumb.
  2. Fold in all-purpose flour, baking soda, salt, and cinnamon until just combined. Mix gently so the batter stays thick and won’t over-develop gluten.
Bake
  1. Pour the batter into the pan, then sprinkle the cinnamon crunch topping generously and evenly over the top. Make sure the surface is well covered so it crackles as it bakes.
  2. Bake at 350°F for 60–70 minutes, until the top is deeply golden and crunchy and a toothpick comes out clean from the center. Let it cool slightly before slicing so the crust shatters instead of smearing.

Notes

For the cleanest slices, cool the loaf 20–30 minutes before cutting, so the cinnamon crust stays crackled. Store covered at room temperature up to 3 days or refrigerate up to 5 days; freeze slices up to 2 months. For a lighter swap, use half the butter called for in the batter and topping with neutral oil (texture may be slightly softer).
