Why this recipe works
I randomly came up with this recipe a few days ago after asking my nutritionist what snacks to make Luise for her tough mudder challenge which was a 20km race.
Bananas are an excellent source of carbohydrates, potassium and vitamin B6, all of which can help boost energy levels.
Oats are a combination of high fibre and complex, slow-digesting carbohydrates. This results in a slow release of sugar into the blood after a meal which provides a sustained supply of energy to the body.

Ingredients to make Breakfast Banana Bars
Using these 3 simple ingredients you will either already have or can get from any supermarket. (brands featured aren’t sponsored)

- Oats – Help to bind the mashed banana. I opt for gluten-free oats but any will work.
- Bananas – When mashed help make the oats stick together.
- Cinnamon – Adds a natural sweetness and spice to these banana bars.
See recipe card for full information on ingredients and quantities.
Substitutions
- Oats – You could also use oat flour to make these bars. You could also try using buckwheat if you’re sensitive to oats.
- Additions – Try adding blueberries, strawberries, or chocolate chips to the mix for some great flavour bursts!
- Cinnamon – This is an optional ingredient that I think boosts the flavour but you could definitely leave it out.
Variations
- Deluxe – I love these healthy oat bars as they are but adding extras is also easy to do! You could also top them with yoghurt or fruit compot.
- Kid friendly – Kids will love these as they are (especially if you put chocolate chips into them). Make mini bars or cut them up into small pieces for little ones. Or serve them with my Peanut Butter Milkshake to get top marks!

How to make Breakfast Banana Bars

Step 3: Line a with baking paper and pour in the mix. Press down firmly with the back of a fork to compact it into the tin. Bake in the oven for 20-25 minutes at 200C.
Hint: Riper bananas make for sweeter oat bars.
Leftovers
Leftover banana oat bars are great! Keep them in an airtight container or bag for up to 2 days at room temperature. Or store them in the fridge or up to 4 days. You can also freeze these for another day. Just allow to defrost overnight.
Recipe FAQs
This can happen if you don’t allow them to cool. They will come out the oven still soft. Just allow them to cool and they will firm up.
Try adding in chocolate chips, nuts, seeds, berries. Whatever you fancy!

Notes
Nutrition














I just tried making this without the bananas but it didn’t stick, what could I use instead of bananas?
Hi
Just want to check carrot cake can we use normal sugar instead of coconut sugar and what can we substitute instead of coconut fat?
Hey Heena, normal sugar will work just fine š the coconut fat is there to replicate a cream cheese style filling but by all means leave it out!
Yom yom yommmmm
Do you have the nutritional values please?
I would love to know rough calories too please for tracking!
Hey Laura, unfortunately I don’t write calories for any of my recipes as it’s not something that’s important to me. I would urge you to input the ingredients into your own app if it’s something you need to know. Thanks
Wow! These are great and so easy to make. Im taking some to work for lunch tomorrow.
Thank you Emily š so pleased you enjoyed them!
These look great. Unfortunately, I only have jumbo oats in the house. Would that work or would the bars fall apart?
Thank you Sam, no worries they should work fine as well š let me know how you get on!
Thanks James, it was fine and theyāre tasty! It must be quite a forgiving recipe as I had to chop out various bits of bad banana and therefore guessed the amount of oats but they still came out well! Cheers.
Just burned my mouth because I couldn’t wait. My kids will be happy tomorrow morning!
I made these the other day and they are so moreish! Are they freezable?
Glad you enjoyed them Jade š I think it should be fine to freeze them.
Awsome
Brilliant simple idea!!
Please get a book in hard back please
I always lose the down loaded one.
Thank you Fiona š most are printing my new eBook to have in their kitchen. Unfortunately a hard copy isn’t viable right now but hopefully will happen in the future. Thanks for the support!
Hi there James. I have been making banana slices for age. You can also swap the oats (I use raw, sprouted, organic, gluten free oats) for Linseed. YuM! š
