Why you’ll love this dish

"So easy and tasty — my whole family loved these bars. Perfect for mornings when we’re rushing out the door."

How this recipe comes together

This is a straightforward mix-and-bake recipe: mash ripe bananas, stir in oats and flavorings, press the batter into a pan, and bake until golden. No eggs or flour needed, and the peanut butter is optional if you want extra richness. The texture falls between a firm cookie and a soft granola bar — chewy, satisfying, and easy to slice.

What you’ll need

2 ripe bananas, 2 cups rolled oats, 1/2 teaspoon ground cinnamon, 1/4 cup honey or maple syrup, 1/4 cup peanut butter (optional), 1/2 teaspoon vanilla extract, Pinch of salt

Substitution tips:

  • Rolled oats: quick oats can work in a pinch but yield a softer, denser bar. For a gluten-free version, ensure your oats are certified gluten-free.
  • Honey or maple syrup: use maple syrup to keep the bars vegan.
  • Peanut butter: swap for almond butter or sunflower seed butter for an allergy-friendly option.
    If you like extra banana flavor, try pairing these with a buttery slice of 3-ingredient banana bread for a banana-forward brunch.

Step-by-step instructions

  1. Preheat the oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper, letting extra hang over the sides for easy removal.
  2. In a large bowl, mash the ripe bananas until mostly smooth with a few small lumps.
  3. Add the rolled oats, ground cinnamon, honey or maple syrup, peanut butter (if using), vanilla extract, and a pinch of salt. Stir until everything is evenly combined.
  4. Transfer the mixture into the prepared pan and press it down firmly and evenly with the back of a spoon or your hands.
  5. Bake for 25–30 minutes, or until the edges turn golden and the center is set.
  6. Let the pan cool completely on a rack, then lift out using the parchment overhang and slice into bars.

Best ways to enjoy it

Serve these bars warm with a smear of yogurt or cooled alongside a fruit salad for breakfast. They also pair well with a small green smoothie or a cup of coffee for a quick work-from-home snack. For lunchboxes, wrap individual bars in parchment — they travel nicely without crumbling.

Storage and reheating tips

  • Fridge: Store cooled bars in an airtight container for up to 5 days.
  • Freezer: Freeze bars in a single layer on a tray, then transfer to a freezer bag for up to 3 months. Thaw overnight in the fridge or on the counter for an hour.
  • Reheating: Warm a bar for 10–15 seconds in the microwave or 5–7 minutes at 300°F (150°C) in the oven to revive that fresh-baked feel.

Pro chef tips

  • Press firmly: Compressing the batter evenly in the pan gives a better hold and cleaner slices.
  • Test for doneness: Insert a toothpick into the center; it should come out mostly clean with a few moist crumbs. Overbaking makes the bars dry.
  • Add texture: Fold in 1/3 cup chopped nuts or seeds to the batter for added crunch without changing bake time.
    For another easy banana recipe that uses very few ingredients, try my favorite 3-ingredient banana bread.

Creative twists

  • Chocolate chip: Stir in 1/3 cup mini chocolate chips before baking.
  • Fruit and nut: Add 1/4 cup raisins or dried cranberries plus 1/4 cup chopped walnuts.
  • Spice it up: Increase cinnamon or add 1/4 teaspoon nutmeg for warm autumn flavors.
  • Protein boost: Mix in a scoop of your favorite protein powder (start with 2 tablespoons and adjust for texture).

Helpful answers

Q: Can I make these without sweetener?
A: If your bananas are very ripe and sweet, you can reduce or omit the honey/maple syrup. Expect a milder sweetness and slightly different texture.

Q: Are these gluten-free?
A: Oats are naturally gluten-free, but contamination can occur. Use certified gluten-free rolled oats to ensure the bars are safe for a gluten-free diet.

Q: How do I make the bars vegan?
A: Use maple syrup instead of honey and ensure any optional add-ins (like chips) are vegan-friendly.
