Place the bananas, berries, oats and apple juice in a high-sided jug. Using the whisk attachment, blitz for a few minutes until the berries and banana are completely smooth and the porridge oats are whizzed up, moving the blender around. Taste for sweetness – if the bananas are lovely and ripe, the mixture should be sweet enough; if not, add honey to taste.
Divide the smoothie mixture into 12 ice-lolly moulds and freeze for at least 2 hours.
To give the lollies a chocolate coating, snap the chocolate into pieces and place in a heatproof bowl over a small pan of simmering water, making sure the water isn’t boiling and the bottom of the bowl doesn’t touch the water. Stir until completely smooth, then take off the heat and leave for 5 minutes.
Wiggle the lolly sticks to loosen the lollies and lift them out. One by one, dip the tips in the chocolate and leave to set for a few minutes before serving. TIP A fun way to serve these lollies is to cover some flower-arranging oasis with fresh flowers, tin foil or coloured tissue paper, and stick the lollies in. For an extra-special entrance, pop in a few sparklers – but be careful!
