Line an 8×8 inch (20×20 cm) baking dish with parchment paper and transfer the mixture into the tin. Press the mixture down firmly with the back of a spoon to compact it—this helps the flapjacks hold together and gives a nicer texture.

Bake at 180°C fan (or 180°C if using a standard oven) for 20 minutes, until the edges are golden and the middle is set.

Allow the flapjacks to cool in the tin for about five minutes so they firm up slightly. Lift them out using the parchment paper and cut into 16 even squares while still slightly warm.

Storing & Freezing

Store the flapjacks in an airtight container at room temperature for up to five days. They also freeze well: wrap individual portions or stack squares separated by parchment. Defrost at room temperature for around an hour—perfect for adding straight to a lunchbox from the freezer.

Instructions

Notes

Keep the flapjacks in an airtight container at room temperature for up to five days.

If you need gluten free oats, buy a certified gluten free brand as oats can be cross-contaminated during processing.
