Ingredients

Oats. If necessary, use certified gluten free oats, or just standard porridge oats if you're not GF. Instant oats are not ideal as they won't give such a good texture.
Banana. The riper the better, as it'll have more natural sweetness. Bananas also help to stick the flapjacks together.
Chocolate banana flapjacks don't taste strongly of banana as there's only one in the recipe, but if you want to make the recipe without banana, replace it with 120 ml of apple sauce.
Butter, coconut oil or olive oil. Choose whichever you prefer.
Honey. Just a tablespoon helps to bring out the rich dark chocolatey flavour. You could also use maple syrup if you prefer.
Cocoa. Make sure it's unsweetened cocoa rather than drinking chocolate. Cocoa gives a fantastic depth of flavour in baking.
It's good for you too, as it is high in antioxidants. (Read more here about the health benefits of cocoa.)
If you're feeling indulgent, why not try this healthy chocolate porridge which is made with cocoa?
If you prefer you can also use cacao powder, which is a less unprocessed form of cocoa.
Dark chocolate. I've also added chunks of chocolate to the cocoa flapjack mixture. Use chocolate chips if you prefer. They are optional, (but more chocolate always seems like a good thing;))
For vegan chocolate flapjacks, use coconut oil or olive oil, maple syrup and dairy free chocolate.
How to make healthy chocolate flapjacks
I use a 20 x 10 cm loaf tin to cook this quantity of mixture. If you want to double the mixture, use a 20 x 20 square tin.
Place a piece of baking paper in the base of the tin so that it is easier to remove the flapjacks.
Preheat the oven to 180 degrees (160 fan).
If you are using butter or coconut oil, melt it gently in a pan over a low heat. If your honey is hard or set, add that to the pan too so that it melts down and is easier to mix in.

Meanwhile, peel and mash the banana with a fork in a large bowl.

Add the oats, cocoa, butter or oil and honey to the mashed banana and mix well.
Stir in the chocolate chunks. It's hard not to eat the mixture at this point, but it tastes even better when cooked!

Spoon the mixture into the prepared tin.

Bake for 30 minutes. If necessary turn the tin partway through baking so that the flapjacks cook evenly.

These chocolate flapjacks smell utterly delicious when straight out the oven, but leave them to cool for a few minutes before taking them out the tin as they might break.
When they are comfortably cool enough to handle, remove from the tin and finish cooling on a wire rack.
Cut into 6 pieces, or make them smaller and turn them into chocolate mini bites if you prefer.

Storage
Healthy chocolate flapjacks will store in an airtight container for 3 or 4 days. You can also wrap them well and freeze for up to 3 months.
Frequently asked questions
That depends on the recipe! Many flapjacks contain a lot of butter and sugar. This cocoa flapjack recipe with dark chocolate has just half a teaspoon of honey and a teaspoon of butter per generous portion. Healthy chocolate flapjacks are also packed with the goodness of wholegrain oats, banana and unsweetened cocoa.
Each of these flapjacks has 177 calories. However, the portions are pretty generous, so if you are trying to cut down on calories, you might want to cut the recipe into 8 portions, or turn them into little flapjack bites to serve with fruit.
Yes, both porridge and rolled oats will make delicious flapjacks. You can also use jumbo oats if you want a super chunky texture. Instant oats are not so good as they are much finer in texture.
