Healthy Banana Quinoa Breakfast Bars Recipe Image with Title

I like to pride myself on the fact that my kids are pretty good eaters and not super picky. However, they are kids, and there are a few healthy foods where I have to use my stealth cooking skills to get them to willingly dig in.

One of those is quinoa. Yes, my friends, I am a quinoa ninja.

A healthy helping of cheddar cheese plus a dunk in ketchup makes Cheesy Quinoa Bites a finger food fave. And what kid doesn’t love barbecue sauce and Ranch dressing? So Barbecue Ranch Quinoa Chicken Salad is actually a welcome addition to dinner.

But the best quinoa recipe for kids that I’ve ever found are these healthy breakfast bars. I’ve made Cinnamon Apple Breakfast Bars and Pumpkin Breakfast Bars, and these are happily devoured in the morning. I just tell the kids they are oatmeal breakfast bars. No need to mention the quinoa!

So I added another favorite fruit – bananas – and these might just be the all-time favorite quinoa breakfast bars I’ve ever made! I can even be super sneaky and get some dreaded spinach into their bellies by serving one with a blueberry smoothie.

Banana Breakfast Bars Recipe

These wholesome bars are super easy to whip up. Combine the dry ingredients, combine the wet ingredients, mix it all together, and bake. And they are good in the fridge for a week, and longer if you freeze them.

Perfect for a portable breakfast on-the-go. They are soft and chewy, but firm enough to hold together if you want to grab one on the way out of the house.

But my kids actually like to eat them on a plate slightly warmed with a bit of butter or even a drizzle of maple syrup or a smear of almond butter.

What do you need to make banana oatmeal breakfast bars?


  • Quick cooking oats – gluten free, if needed
  • Quinoa – cook quinoa using your favorite method and cool completely
  • Baking powder
  • Ground flax seed – you can purchase flax meal or grind flax seeds in your blender
  • Cinnamon
  • Honey – can also use maple syrup or agave
  • Overripe bananas – mashed, you’ll need 2 or 3, depending on the size
  • Egg – an egg, egg whites, or liquid egg or egg white substitute in this recipe and it will turn out fine. Use the equivalent of one egg or two egg whites.
  • Almond butter – you can also use another nut butter or sunflower seed butter
  • Vanilla extract
  • Walnuts – chopped, and lightly toasted, if desired

MAKE THEM NUT-FREE: use sunflower seed butter for the almond butter and omit the walnuts or substitute with pumpkin seeds if you’d still like that bit of crunch. Or try chocolate chips!


  • 9-inch square baking pan
  • parchment paper – lining your baking pan with parchment the bars much easier to remove once they are cooled so you can cut them into nice squares.
  • two bowls
  • whisk
  • spatula
  • serrated knife – using a serrated knife and cutting with a gentle sawing motion will give you the cleanest cut.

Brianne’s Banana Breakfast Bars Recipe Pro Tips

How much dry quinoa do you need to make 1 cup of cooked quinoa?

Quinoa typically triples in volume when you cook it. So if you want to make exactly 1 cup of cooked quinoa, you will want to cook 1/3 cup dry quinoa in 2/3 cups of water or other liquid.

However, I recommend making a bigger batch because you can keep it in the fridge for up to a week and use it in a number of other recipes like Berry Banana Quinoa Yogurt Parfaits or Mango Avocado Quinoa Chicken Salad.

How do you cook quinoa?

This recipe uses cooked and cooled quinoa. You can see how to cook quinoa using the stove, microwave, slow cooker, rice cooker, or Instant Pot.

Or simply follow the package instructions. Typically you’ll rinse the quinoa, add to a pot with water, bring to a boil, and simmer for 10-15 minutes. To cool it quickly, spread it out in a thin layer on a baking sheet.

How do you store oatmeal breakfast bars?

You can keep the bars at room temperature in an airtight container for a day or so, but I would recommend storing them in the refrigerator where they will last several days to a week.

Can oatmeal breakfast bars be frozen?

Yes, these bars are freezer-friendly. Store them in a plastic freezer storage bag or an airtight container, removing as much of the air as possible. Kept frozen, they will be good for up to two months. If you leave them longer then that, they are still safe to eat. But the quality and flavor may be affected.

It is not necessary to individually wrap the bars. But to keep them tasting their best, I would recommend wrapping or packaging them in groups of two to four.
