RECIPE NOTES & TIPS
Use full-fat sweetened condensed milk and cream - this will ensure that the ingredients whip up best. Light or low fat versions will not give the right consistency in this recipe.
Beat base ingredients together well - until you have a thick pouring consistency, but don't overbeat, as the cream may curdle or go a little grainy.
By adding extra spread and crumbled biscuits in layers, it ensures that the spread and biscuits are evenly mixed through the ice cream.
Wrap the tin well in plastic wrap, or add a lid to the container when ready to freeze.
Freeze for a minimum of four hours, or until set.
Biscoff ice cream can be frozen for up to 3 months.
