In the food processor, blitz the TREK Power Biscoff® bars into small chunks.
With an electric mixer, mix the cream cheese, powdered sugar, and Biscoff® spread until smooth.
In a separate bowl, whip the heavy cream until stiff peaks form.
Add the whipped cream to the cream cheese mixture and whip until combined.
Fold in the TREK Power Biscoff® bar chunks.
Spread the mixture evenly over the biscuit base and chill in the fridge for at least 5-6 hours, preferably overnight.
