Storage: Wrap cooled bread or cake tightly in plastic wrap or store in an airtight container at room temperature for up to 3 days. For longer storage, freeze for up to 3 months.
Variations: Add 1/2 cup chopped nuts (walnuts, pecans, or almonds) to the banana bread batter for added texture and flavor.
Tip: Use bananas that are very ripe with brown spots for the best sweetness and moisture content.
Substitution: If you don't have buttermilk for the cake, you can substitute milk with 1 tablespoon of lemon juice or vinegar added to it; let it sit for 5 minutes before using.
