In the Ninja Creami container, whisk together the milk, custard powder, and Biscoff spread until smooth.
Freeze for 24 hours or until frozen solid.
Once frozen, process using the ‘Light Ice Cream’ setting, then ‘Re-spin’.
Add two of the Biscoff biscuits into the centre and spin on the ‘Mix-in’ setting.
Scoop into a bowl and top with extra melted Biscoff and crushed biscoff biscuits.
