Banana & Peanut Butter Flapjacks

Healthy and nutritious banana and peanut butter flapjacks sweetened with honey. The flapjacks are gluten, dairy and refined sugar free.

Banana and Peanut Butter Flapjacks

I make flapjacks (or oat bars as they are known in the US) a lot, and these Banana & Peanut Butter flapjacks are one of my favourites at the moment. Packed with protein and refined sugar free, they make fab healthy breakfasts on the go. I often go swimming in the morning after the school run, so I take one of these to have in the car after my swim and they keep me nice and full until lunchtime.

Using Up Over Ripe Banana's

I'm always looking for recipes to use up those pesky black banana's in the fruit bowl. These banana and choc chip muffins are my usual go to recipe, as is this yummy banana cake, but I wanted to find another way to use up over ripe banana's. Who knew banana's in flapjacks were so good? They make the flapjack lovely and squidgy. Just the way I like them!

Step By Step Banana and Peanut Butter Flapjacks

Melt the peanut butter and honey in a heavy bottom saucepan over a medium heat. Keep stirring to prevent the mixture catching on the bottom of the pan.

Next you need to mash the over-ripe banana's with a fork and add it to the peanut butter and honey mixture.

Then its time to stir in the gluten free oats. I added in a handful of chopped walnuts too but it's completely optional.You could try chopped dried apricot if you wanted to make them more fruity.

Making Flapjacks in a saucepan

Press the flapjack mixture into a lined baking tin and bake in the oven for 15 - 20 minutes. Leave to cool before cutting into squares. They will keep for up to 10 days in an airtight container.

Top Tips For Making Banana and Peanut Butter Flapjacks

  • These flapjacks are refined sugar free but if you like your flapjacks on the sweeter side add 150g light brown sugar when you melt together the peanut butter and honey.
  • Add chopped dried fruit or nuts such as walnuts or pecans for added texture and taste. A large  handful should be enough.
  • If you're not too keen on peanut butter, replace it with salted butter. The same goes for honey, if you prefer golden syrup use that instead. The result will be a lot sweeter (and obviously not refined sugar free anymore!

    1. My kids love flapjacks too. These banana and peanut butter ones were really yummy. Will definitely be making these again soon.

  2. I haven't had a flapjack in such a while, since you don't really get them here, but I do sometimes have them for nostalgia's sake when I am back in the UK. I should really make some, like the idea of banana and PB flavored ones.
