1. Line a 26 x 16cm baking tin with nonstick baking paper. Blitz the dates in a food processor until finely chopped and sticky, adding 2 tbsp of water if needed to help the mixture come together.
2. In a small saucepan, heat the peanut butter, maple syrup and spread to melt together, mixing with a wooden spoon to combine.
3. Mix the oats, rice snaps, nuts, 4 tbsp 4-seed mix and the chia seeds in a mixing bowl. Pour in the peanut butter mixture and the blitzed dates, then use a wooden spoon to mix very well.
4. Press the mixture into the lined baking tin, then sprinkle the remaining 1 tbsp 4-seed mix evenly over the top, pressing the seeds in with your fngers. Transfer to the fridge for at least 1 hr to set. Once set, cut the flapjacks into 10 bars. Will keep for up to 5 days in an airtight container in the fridge.

Tip: Use your favourite nuts for this recipe - walnuts, pecans, macadamias and almonds all work well.
