1. Pre heat oven to 350 degrees
2. Line a 9 inch pan with parchment paper and spray with cooking spray
3. Place cookies in a food processor and process until finely ground. In a medium bowl, mix the cookie crumbs with melted butter until crumbs are evenly moistened. Press mixture into the bottom of your pan, using the back of a measuring cup, press down to form an even layer, about 1 inch thick. You will have some left over cookie crumbs, save those as extra toppings. Bake the crust for 8 mins and then freeze for up to 1 hour.
4. In a large bowl, combine the heavy whipping cream, condensed milk and vanilla extract. Using an electric mixer, whisk on low speed for 30 seconds. Once the cream starts to thicken, turn the setting to medium high and whisk until the mixture turns even thicker then turn the setting to high and keep whisking for about 2 minutes until you get stiff peaks or resembles whipped cream.
5. Melt the Biscoff spread or cookie butter for 20 seconds in the microwave.
6. Remove the Biscoff crust from the freezer and chop the crust into chunks. Add the chunks to the ice cream mixture along with milk chocolate chunks and 2 tbsp of melted Biscoff spread and gently fold to evenly mix. (Add as much or as little of the Biscoff and chocolate chunks as you like)
7. Take about one third or your ice cream mixture and spread it out into the bottom of your loaf tin. Next take some of your melted Biscoff spread and pour it over the ice cream (Not to much, its quite sweet) We like to use a tooth pick and swirl the spread into the ice cream mixture. Next top it with more Biscoff cookie chunks and chocolate chunks.
8. Add another layer of ice cream and finish with extra Biscoff chunks and chocolate chunks.
9. Cover with clingfilm and freeze for 4-6 hours until ice cream sets.
10. To serve, let the ice cream sit out for a few minutes before scooping and top with remaining cookie crumbs and extra chocolate chunks.
