Line a tray with cling film.
Lay the bread onto the tray, ensuring each piece is not overlapping.
In a saucepan over a medium heat, bring the milk and Shape It Powder to the boil, stirring occasionally.
Use a fork to pierce holes in the bread to help the milk mixture soak in evenly.
Pour half of the hot milk mixture over the bread, and keep the remaining liquid hot. Allow it to soak in for 1 minute.
Turn the bread over and pour the remaining hot milk solution over any unsoaked parts. Allow the bread to soak and refrigerate for 2–3 hours.
