What's in these Peanut Butter Flapjacks?
- Butter: You may use salted or unsalted butter. It gives an extra rich flavour and keeps the flapjacks moist.
- Dark brown soft sugar: This adds a distinct colour and flavour to the dish.
- Golden syrup: This recipe calls for golden syrup, which is thick and has a deep caramelized & buttery flavour. It gives a lovely sticky texture to the dish.
- Peanut butter: This recipe uses extra smooth peanut butter.
- Rolled oats: They make the flapjacks chewy and gives the best texture. I used jumbo oats. However, you can use porridge oats if you like.
- Vanilla extract: For that extra dash of flavour.
- Milk chocolate chips: You may also substitute with dark chocolate chips based on your preference.
