Place the chia seeds in a small bowl with 5 tbsp boiling water and leave for 10 minutes to soak.
Meanwhile, place the dates, 200g apricots, cinnamon and coconut oil in a food processor and blitz to give a coarse paste. Add the soaked chia seeds and pulse until well blended.
Transfer to a large bowl and stir in the remaining apricots, chopped and 100g Walnuts. Press into the prepared tin. Mix the remaining Walnuts and seeds together, sprinkle over the date mix and press in gently. Allow to chill until required.
Cut into 12 rectangles to serve.
