Chocolate Flapjack Recipe Ingredients
Below are the few ingredients used, you’ll probably have most of the ingredients at home already. If not, you can get what you need online or at your local supermarket.
- Porridge Oats: Any brand of porridge oats is fine to use.
- Golden Syrup: Golden syrup helps to bind the dry ingredients together; it also adds a delicious sweet caramel flavour to the flapjacks.
- Butter: The butter I used was salted, feel free to use either salted or unsalted butter.
- Brown Sugar: I used light brown muscovado sugar but any light brown sugar will do. Using this type of sugar adds a good flavour to the flapjacks. Caster sugar is a good alternative.
- Cocoa Powder: Adding cocoa powder to this chocolate flapjack recipe is a must! It makes the biggest difference and adds a rich, dark and indulgent taste. This is my favourite cocoa powder ever but any brand will do.
- Chocolate: I added both white and milk chocolate chips to this flapjack recipe which is also covered in melted chocolate. Adding the chocolate topping is an optional step!

Equipment
Below is the main equipment needed:
- Baking Tin: This recipe uses a 9″ baking tin to create 12 big slices or you can make 16 medium sizes.
- Parchment Paper: Used to line the baking tin. It makes removing the flapjacks a lot easier and helps to prevent scratches.
- Mixing Bowls: You’ll need a large enough mixing bowl to mix the melted butter mixture and oats together.
- Offset Spatula: To smooth-out the chocolate topping.
