What you'll love about the recipe

  • Healthy peanut butter flapjacks are delicious and satisfying. They are slightly chewy and slightly crunchy like a granola bar. Packed with wholegrain oats, they'll keep you feeling full and energised
  • Made with just 3 everyday store cupboard ingredients, these easy oat bars will be cooling on your kitchen counter in just 30 minutes
  • Dairy free flapjacks are low in sugar and gluten free. Peanut butter provides plenty of richness, so there's no butter and no additional oil in the recipe

Ingredients

Peanut butter, oats, honey.

Oats. Make sure you use certified gluten free oats if necessary. You'll need porridge or rolled oats. Steel cut or pinhead oats are not suitable as they'll remain too hard and chewy

Peanut butter. You can use smooth or crunchy peanut butter. For the best healthy flapjacks, make sure your peanut butter is free from added oils and sugar

Honey. There's just a little honey in these flapjacks - they are sugar free and made without syrup. The honey both sweetens the mixture and helps the oats to stick together. As you'll be melting the honey, this recipe is ideal for crystallised honey that you want to use up

Optional ingredients and variations

I love the flavour of these simple 3 ingredient healthy peanut butter flapjacks. But there's lots of variations you can try to make the recipe your own.

  • Nuts and seeds. Of course you can add some chopped unsalted peanuts to the recipe. Or try some pumpkin or sunflower seeds for extra texture. Bear in mind that if you add too many chunky ingredients, the flapjacks will be more likely to crumble.
  • You can also add dried fruit such as raisins, sultanas or chopped apricots or dates.
  • Chocolate chips are a good addition to peanut butter flapjacks.
  • Or try some of your favourite spices. A teaspoon of ground cinnamon goes very well.

If you are short on time, you might also like to try these no-bake flapjacks with peanut butter. Just mix the ingredients and pop them in the fridge.

How to make healthy peanut butter flapjacks

Line the base of an 18 x 18cm baking tin with baking paper. Preheat the oven to 160 degrees (140 fan)

Melt the peanut butter and honey together in a saucepan over a very low heat. As soon as the mixture has melted, remove it from the heat so that it doesn't turn to caramel!

Stir in the oats, and any optional ingredients, and stir well. Ensure that all the oats are coated by the peanut butter mixture.

Spoon the mixture into the lined baking tray. Press down firmly with the back of a spoon, ensuring that you get into the corners. This is important to ensure that the baked flapjacks hold together well.

Allow to cool in the tin and cut into 9 squares. If you are making these healthy peanut butter flapjacks for young children, you might want to cut them a little smaller.

Serving and storage

Healthy peanut butter flapjacks can be served as a quick on-the-go breakfast. They are perfect as a healthy snack, or energy bar. After school, after the gym, or any time you need a pick-me-up.

Store the flapjacks in an airtight container for up to a week. They can also be frozen for longer storage.

Frequently asked questions

How many calories in a peanut butter flapjack?

One generous slice of these healthy peanut butter flapjacks has 200 calories. You could also cut them a little smaller to reduce the calories;) They are very satisfying and will keep you feeling energised.

Are flapjacks healthier than cake?

Of course, that really depends on both the flapjack and the cake, as it's possible to have healthy and unhealthy versions of both. Many flapjacks and cakes can be very high in sugar and saturated fat. These healthy peanut butter flapjacks are low in added sugar and saturated fat. In addition, they are made with healthy wholegrains which are high in fibre.

      Hi, yes you can freeze healthy peanut butter flapjacks. Wrap them well and defrost at room temperature.

    These came out so good. I used agave instead of honey and I love these. So delicious, perfect texture of slightly chewy. I also made a chocolate one by adding a little more peanut butter and cocoa powder and it was soo good! Thank you for this incredibly simple yet delicious flapjack recipe.

      Hi, thanks for your question. You've prompted me to realise that at the moment the recipe states grams for the honey and it should actually read mls. I going to change this now. In answer to your question, you'll need 120ml of maple syrup - it's an equal replacement for honey. I hope you enjoy the flapjacks!

    Have not tried yet. Can I use sugar instead of honey (I know not so healthy). I don’t like honey!

      Hi Sue. It would be better to use another 'liquid' sweetener rather than honey, otherwise you'll affect the texture of the flapjacks and they won't stick together. How about maple syrup or golden syrup instead?
