A fantastic way to use up a whole bunch of overripe bananas sitting on the counter. Turn them into these tasty snack bars! My kids love them.
🧄 Ingredient notes
What do you need to make these banana oat bars?
- ripe (or overripe), spotty bananas
- rolled oats (old fashioned or quick cook oats)
- ground cinnamon
- ground flaxseed
- baking powder
Top your banana oatmeal bars with any toppings of your choice!
For the photos, I used coconut flakes, pumpkin seeds and a drizzle of brown rice syrup. Another favorite of my family is mini dark chocolate chips and chopped pecans or walnuts. Peanut butter or prepared PB2 is also amazing on these!
Get creative with your toppings, if you'd like. Or, leave them plain, whatever you and your family prefer. I'll share some ideas for different toppings below!

The overripe bananas give the bars sweetness and moisture. The oatmeal gives them substance, nutrition and helps everything stick together, along with the ground flaxseed.
And, the ground cinnamon is for flavor! You can switch up the cinnamon with vanilla extract, if you'd like. See my recipe notes below for suggestions on additional alternative spices and flavoring.
No egg at all is needed for these bars. The bananas and oatmeal work together with the ground flaxseed to hold everything together.
No flour is needed for these banana oat bars. The oats (either old fashioned oats or quick oats) combined with the mashed banana and ground flaxseed keep everything together.
The texture for these banana oatmeal bars is like a soft and chewy breakfast granola bar. The ripe bananas give them sweetness. If you'd like them to be a little sweeter, you can drizzle them with brown rice syrup, maple syrup, agave nectar or honey before baking.
You could also top them with something sweet, like chocolate chips, chocolate chunks, diced dates, raisins, chopped dried apricot, chopped dried peach, etc.
Mash the bananas
Mash with potato masher or fork. Make sure they are mashed very well, with only very small chunks remaining (see picture #1).
Mix in ground flax, cinnamon, baking powder and then oats
Stir everything together. See picture #5 for what the completed batter should look like.
Spread, shape, top, drizzle and bake!
These bars will not spread out or rise too much, so make them into the shape, width and height you want from the beginning.
It's helpful to gently press any toppings down into the batter so they don't fall off after baking and cutting. That's what you see me doing in picture #8.
Definitely use a silicone mat or parchment paper to line your baking sheet, because these will stick without it. You could also make these in a 13x9 baking pan.

- Use parchment paper or a silicone mat on your baking sheet, otherwise they will stick.
- Lightly press toppings down before drizzling any liquid sweetener and before baking.
- Mash your bananas very well.
- The more ripe your bananas are, the sweeter these bars will be naturally, without adding any sweetener to them. So, choose those spotty bananas for this! The same kind of bananas you would use to make banana bread.

Healthy Banana Oatmeal Bars (5 ingredients, no flour, no egg, sugar free)
Basic Banana Oatmeal Bars
- Preheat oven to 350°F.
- In a large bowl, mash the banana very well with a potato masher or fork.
- Add ground cinnamon, ground flaxseed and baking powder and mix together with banana.
- Add rolled oats to the bowl and mix together well.
- Line a baking sheet or 13x9 baking dish with parchment paper or a silicone mat. Spread batter evenly in a rectangle on lined baking sheet. Keep the batter on the parchment/silicone mat, so it doesn't stick. Shape the batter into a wide rectangle about 1-inch deep. This batter does not spread as it bakes. It will stay in place and harden into chewy bars.
- Add dry toppings, if using (like coconut flakes, pepitas) across surface. Gently press the toppings into the batter with your fingers or a spoon.
- Drizzle wet topping, if using (like brown rice syrup) across surface.
- Bake banana oatmeal bars in oven for 25 minutes, or until firm to the touch.
- Allow to cool and then slice into bars. Store cut bars in refrigerator for 3-4 days.
