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!

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.

Nutrition














These were delicious! Thank you for sharing. š
Thanks so much š
It would be helpful to know what the nutritional info relates to! Is it per portion as the size you made? Per full batch? Per 100g? Some kind of reference please
Sure, it’s per portion for meals or for this recipe per bar š enjoy
size of tin would be useful
I used a 23cm square tin.
The online grams to ounces converter i used says that 400 grams is equal to a little over 14 ounces, which is less than 2 cups. Your recipe says it’s 4 cups. Which do I use???
Hi, always go with the converted weight as more accurate than using cups. enjoy
