Ingredients

Wet Ingredients
  • 2 large eggs
  • 1 cup mashed bananas
  • ¾ cup sugar (you can lower this to ⅓–½ cup for a less-sweet loaf)
  • ⅓ cup oil
  • ½ cup Greek yogurt
Dry Ingredients
  • 1 ¾ cups whole wheat flour (see notes for alternative options)
  • ¼ cup cornstarch or additional whole wheat flour
  • 2 teaspoons ground cinnamon
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon salt
Crumb Topping
  • ½ cup flour (plain or whole wheat)
  • ½ cup brown sugar
  • 1 teaspoon cinnamon
  • ¼ cup butter

Instructions 

1. Get the Pan Ready
Heat your oven to 360°F. Line and grease a 9×5 inch loaf pan.
2. Mix the Topping
Combine flour, brown sugar, and cinnamon in a medium bowl. Add the butter and work it in with your fingertips until you have a bowl of soft crumbs. Keep refrigerated until it’s time to use.
3. Combine Dry Ingredients
Add all dry ingredients to a large bowl and mix until evenly blended.
4. Combine Wet Ingredients
In a separate large measuring jug, whisk all wet ingredients together until smooth.
5. Bring the Batter Together
Pour the wet mixture into the dry mixture. Fold gently with a spatula—stop as soon as the flour disappears (it’s fine if the batter is a little lumpy). Spread into the loaf pan and sprinkle the crumb topping evenly over the surface.
6. Bake
Bake 50–60 minutes, or until a toothpick inserted in the center comes out clean.
Let the loaf rest in the pan for 10 minutes, then remove and cool on a wire rack. Peel off the parchment before cooling completely.
 
Recipe Notes
About the Whole Wheat Flour
This loaf does have the hearty flavor that comes with whole wheat. If you’d prefer a different texture, any of these combinations work:
  • 1 ¾ cups whole wheat flour + ¼ cup cornstarch (as written)
  • 1 cup whole wheat flour + 1 cup all-purpose flour
  • 2 cups all-purpose flour (add 1–2 extra tablespoons if the batter feels thin)
Mixing Tip
  • Avoid overmixing—this is key to keeping the bread tender. Stick with a spoon or spatula, not a mixer or whisk.
Muffin Option
  • The batter works beautifully as muffins. Bake for about 20 minutes.
Moisture Tips
  • The Greek yogurt adds richness and moisture even when using all whole wheat flour. Again, don’t overmix or the crumb will turn dense and gummy.
Crumb Topping Tips
To keep the topping crisp and crumbly:
  • Use cold butter—no substitutions.
  • If the mixture looks too wet, add a little extra flour.
  • Gently press the topping onto the batter to help it stick during baking.
Choosing Bananas
  • Use ripe bananas with plenty of brown spots; very black, overly fermented bananas may make the flavor too intense.
 
Storage
Wrap the cooled loaf in foil or keep it in an airtight container.
  • Refrigerator: up to 5 days
  • Freezer: up to 3 months
To freeze, wrap the loaf tightly in plastic wrap, then foil. Defrost on a wire rack at room temperature. You can warm slices in the oven if desired.
Freezing tip: Freeze slices individually with parchment between them so you can grab exactly what you need.
