Greek Yogurt Banana Bread with Walnuts
Tender, moist banana bread enriched with Greek yogurt for tangy depth and structural stability. Whole wheat flour adds nutty complexity while walnuts provide textural contrast. This version prioritizes moisture and protein retention, making it ideal for breakfast, snacks, or dessert. The yogurt replaces some fat traditionally used, creating a lighter crumb without sacrificing richness. Serve warm with butter or cream cheese, or pack slices for lunchboxes. Best enjoyed within days of baking.

Tips
Mash bananas until mostly smooth with a few small lumps for better texture and moisture distribution throughout the crumb.
Don't overmix the batter once you add dry ingredients; stop as soon as flour is incorporated to avoid developing gluten and creating a dense loaf.
Use a toothpick or cake tester to check doneness; the center should have a few moist crumbs but no wet batter clinging to it.
Good to Know
Wrap cooled bread tightly in plastic wrap or store in an airtight container at room temperature for up to 3 days, or refrigerate up to 5 days. Freezes well for up to 3 months wrapped individually.
Prepare batter up to 4 hours ahead and refrigerate. Bake fresh when ready. Baked loaf freezes excellently for later reheating.
Serve warm or at room temperature with softened butter, cream cheese, or a drizzle of honey. Pairs well with coffee or tea.
Common Mistakes
Use 2 cups mashed banana (as stated in instructions) to avoid dense, gummy crumb from excess moisture.
Stop mixing as soon as dry ingredients are combined to avoid overmixing, which creates tough, tight texture.
Use an oven thermometer to verify 350F/180C to avoid under or overbaking, which affects doneness.

FAQ
Can I use overripe bananas?
Yes, very ripe (nearly black-skinned) bananas are ideal. They have higher sugar content and mash more easily, yielding a sweeter, moister loaf. Measure the final mash at 2 cups as directed.
What if I don't have Greek yogurt?
Regular yogurt, sour cream, or buttermilk work well in equal amounts. Greek yogurt provides extra protein and slight tang; substitutes will be slightly thinner. Moisture remains similar across these swaps.
How long does banana bread keep, and can I freeze it?
Wrapped tightly, it keeps 3 days at room temperature or up to 5 days refrigerated. Freezes beautifully for 3 months wrapped in plastic wrap then foil. Thaw at room temperature or reheat gently in a 300F oven.
