Fruity, Nutty, Oaty Flapjack Bars are easy to make and brilliant for filling lunch boxes and cake tins. Best of all they are endlessly adaptable to the ingredients you have in your larder. This recipe includes two bananas, peanut butter, dried cranberries, pistachios, and almonds, but any dried fruit and nuts will do, or you can use seeds. You can make the Flapjack Bars with butter or go dairy-free with coconut oil.
The Flapjack Bars may not be a low-calorie snack, although you can cut them into smaller slices. However, they are ideal to add to a lunch box or take on a long walk or picnic as they are packed full of energy. If you read the ingredients on most commercial flapjack bars you will be horrified at just how processed they actually are. At least if you make them yourself you will know exactly what you are eating.

I used my Optimum ThermoCook to mix and melt the wet ingredients. The Thermocook is a multi-function kitchen appliance. If you’d like to find out more about the ThermoCook you can read my review or visit the ThermoCook website.
It’s an amazing piece of kitchen kit that I use all the time, it has largely replaced my food-processor and blender. The ability to control the temperature and have integral stirring makes it invaluable for cooked recipes like sauces, curds, and custards.

Choclette says
Haha, snap Janice. I made peanut butter flapjacks a couple of days ago – not in my Thermocook though. I’ve never used peanut butter in flapjacks before and now I’m wondering why ever not – they are delicious. Yours look perfect.
Janice Pattie says
Thanks Choclette, I think the peanut butter creates a great texture, not too chewy as some can be.
Karen says
I do love a good flapjack and this batch looks very tasty and just the job to accompany a culpa.
Janice Pattie says
Thanks Karen, indeed they are excellent with a cup of tea or coffee.
Lucy @ BakingQueen74 says
These flapjacks look amazing! As we may have a peanut allergy in our youngest, I will try them with almond butter instead. Love flapjacks and using the Thermocook to make them sounds so convenient!
Janice Pattie says
Thanks Lucy, I’m sure any kind of nut butter would work equally well.
