Wholesome Ingredients for These Banana Squares
Every ingredient serves a purpose, creating layers of flavor and nutrition in these delightful dessert bars:
- Ripe bananas: The star of the show, bananas bring natural sweetness and moisture. Look for bananas with plenty of brown spots for the best flavor. Need a substitute? Try pureed applesauce for a similar texture.
- Chopped walnuts: Optional but encouraged, walnuts add a satisfying crunch and are packed with omega-3 fatty acids. Swap with pecans or skip altogether if nut-free.
- Buttermilk: This adds tangy richness to the batter and activates the baking soda for a tender crumb. No buttermilk? Make your own by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk.
- All-purpose flour: The base for the squares—consider substituting half with whole wheat flour for added fiber.
