Serving Suggestions
These versatile bars are delicious on their own, but you can elevate them in several ways. For breakfast, serve with a dollop of Greek yogurt and a drizzle of honey. As a dessert, warm slightly and top with a scoop of vanilla ice cream or a swirl of whipped cream.
They also pair wonderfully with a hot cup of coffee or a cold glass of milk, making them perfect for an afternoon pick-me-up or lunchbox treat.
Notes
- Store in an airtight container at room temperature for up to 3 days or refrigerate for up to a week
- Freeze individually wrapped bars for up to 3 months; thaw at room temperature or microwave for 20-30 seconds
- Bars are done when the edges are golden brown and the center is set but still slightly soft
FAQs
Can I make these bars vegan?
Yes! Replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) and ensure your chocolate chips are dairy-free.
My bars turned out too moist. What went wrong?
This could be due to extra-large or very ripe bananas adding more moisture. Next time, add an extra 2-3 tablespoons of flour or oats to absorb the excess moisture.
Can I reduce the sweetener?
Absolutely. The ripe bananas provide natural sweetness, so you can reduce the honey or maple syrup to 2-3 tablespoons if preferred.
Are these suitable for school lunches with nut allergies?
No, these contain peanut butter. However, you can substitute sunflower seed butter to make them school-safe for children with nut allergies.
