Our chocolate oat bars are flavoured with peanut butter and use five ingredients in total
If you like flapjacks you will enjoy the flavours in our chocolate oat bars. We have used crunchy peanut butter for a delicious flavour and interesting texture. The light Muscovado sugar adds a subtle caramel-like flavour but you could use caster sugar if that’s all you have in the cupboard. We use regular porridge oats rather than jumbo oats because the bars stick together better but again you can use whatever you prefer.
Ingredients
- 175g crunchy peanut butter
- 75g light muscovado sugar
- 6 tbsp golden syrup
- 175g porridge oats
- 150g milk or plain chocolate

Method
- Heat the oven to 180C (160C fan, Gas 4). Grease and line the base of a 20cm square, shallow cake tin with baking parchment.
- Place the peanut butter, sugar and syrup in a pan and heat gently until smooth. Tip the oats into the pan and stir until well coated.
- Pack the mixture firmly into the prepared tin and bake for 20-25 minutes until just turning brown at the edges. Allow to cool in the tin.
- Break the chocolate into squares and place in a bowl over a pan of gently simmering water. Allow to melt then spread over the cooled flapjacks and allow to set in the fridge. Cut into squares.
Top tips for making chocolate oat bars with peanut butter
Before you make this recipe read through our tips and tricks below for information on ingredient substitutions and advice on how to store the finished bake.
Can you freeze chocolate oat bars?
If you want to freeze these chocolate oat bars it would be best to chop the chocolate into small pieces and mix with the other ingredients. Then once cooked, cooled and cut into portions, tightly wrap the bars in clingfilm and freeze. Defrost before eating and then you could add a chocolate topping if liked. If you don’t need to freeze the bars, simply store in a cake tin or airtight container for up to one week.
Can I use smooth peanut butter instead of crunchy?
Yes you can use whichever peanut butter you prefer. You can also swap it for another nut butter such as almond or cashew if you prefer. For a more indulgent substitution you can use chocolate spreads like Nutella too.
