Grab a big bowl and blend the heavy cream and Biscoff spread until you get a smooth mixture with medium peaks. Be careful not to overbeat; we don't want the mix to separate!
Transfer the creamy goodness into a larger bowl or separate containers.
Pop it in the fridge for about 30 minutes or until it's refreshingly cool.
Time to add the finishing touches! Sprinkle some extra Biscoff spread and, if you're feeling fancy, throw in a few Biscoff cookies on top.
Voila! Your Biscoff Mousse is ready to be enjoyed. Serve it up immediately and savor the deliciousness!
