If you’ve been following our blog for a while you’ll know that we’re often looking for something to make with our leftover bananas. While banana bread is our favourite and we’ve loads for you to try if you like banana bread as well, we also like to try something new. This time, I found a recipe for banana and chocolate chip slice in a Mary Berry cookbook and made a few tweaks to use ingredients we had to hand.  And rather than using chocolate chips we used M&Ms to decorate – they added a nice zip of chocolate and made them look fun (and very appealing to little eyes).


Preheat the oven to 180C/160C Fan / Gas 4 / 350F and prepare a small baking tin.

Get your kids to grease a tin with butter. Either a small 6 inch square baking tray or, we used a small loaf tin. Line it with greaseproof/baking paper.

Make the crumb

Get your kids to measure the flour (75g), oats (75g), and sugar (75g) and add to a large bowl. 

Measure the butter and cut it into little pieces before adding to your bowl.

Rub the butter in using your fingertips until the mixture looks like breadcrumbs. This is one of my kids favourite things to do – they love getting their hands messy and getting to feel everything with their hands.

Add half the mixture to the base of your baking tray and get your little one to press it down with the back of a spoon.

Add the bananas

Get your kids to slice the bananas (this is a great task for little chefs who like to practice cutting but can’t use a sharp knife), and then arrange them over your crumb base.


Sprinkle the rest of the crumble on top and press it down.

Add the M&Ms

Sprinkle the M&Ms over the top of your banana crumble. If you don’t have M&Ms chocolate chips will work just as well.

Bake the banana and chocolate chip slice

Bake the banana and M&M slice into the oven for around 25 minutes. It’s ready when the top is golden brown.

Leave it to cool in the tin then slice into bars and serve.
