Place the marshmallow mixture in to a large piping bag with a small round piping nozzle.
Pipe a generous blob of māngohe (marshmallow) on to every second pihikete (biscuit) and let it sit for 20 minutes so the māngohe (marshmallow) has time to set.
Place a biscuit on top of each one and press it gently down. Allow the marshmallow to set for at least an hour in the fridge before eating!
These will keep well for up to a week in a sealed container in the fridge.
