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
- 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
-
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)
- Avoid overmixing—this is key to keeping the bread tender. Stick with a spoon or spatula, not a mixer or whisk.
- The batter works beautifully as muffins. Bake for about 20 minutes.
- 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.
-
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.
- Use ripe bananas with plenty of brown spots; very black, overly fermented bananas may make the flavor too intense.

Refrigerator: up to 5 days
- Freezer: up to 3 months
- Can I use any bananas, or do they need to be really ripe?
Use spotty, soft bananas — they’re sweeter and make the loaf moister.
If they’re still yellow and firm, the flavour just won’t be the same. Trust me on this one!
- How much should I mix the batter?
Barely. Seriously — stop mixing as soon as the flour disappears.
Overmixing is the fast track to a dense, rubbery loaf… and nobody wants that. Fold gently and walk away!
- The top is browning too quickly! What do I do?
Just tent the loaf with foil and keep baking.
This protects the top while the centre cooks through. Easy fix, crisis averted.
- Why did my loaf sink in the middle or turn gummy?
This usually means too much moisture (extra-large bananas, extra yogurt, etc.)
OR the oven wasn’t fully preheated. Measure accurately, don’t eyeball, and make sure that oven is hot before the batter goes in.
- How do I keep my banana bread soft and moist?
Oil + Greek yogurt + ripe bananas = a beautifully tender loaf.
Bake just until a toothpick comes out clean, then pull it out — overbaking is the real moisture thief.
