Add your double cream, condensed milk and Biscoff spread to a large bowl.
Whisk on a low-medium speed until the ingredients are smooth and even.
Turn the whisk up a bit higher and whisk until the mixture is starting to thicken and is lovely and smooth. It'll only take 1-2 minutes. It doesn't need to be extremely thick, it just needs to be smooth and starting to thicken.
Alternatively, you can whip the cream up to soft peaks, and fold the ingredients together. The Biscoff spread may need mixing on it's own briefly as it's firmer than the other ingredients!
For Assembly
Melt your 125g Biscoff spread until smooth - this takes 20-30 seconds in the microwave. Also crush your biscuits to chunks!
Add 1/3 of your ice cream mix to your tin/tub and swirl through 1/3 of the melted spread and biscuits.
Repeat twice more so all the ingredients are used up.
Put the tub/tin your freezer till frozen and firm and enjoy!
Notes
You can of course use an ice cream maker if you have one - but this is designed for those who don't!
I used the smooth Biscoff spread but you can use the Crunchy spread if you prefer instead!
The extra Biscoff spread/Biscuits are optional, but delicious.
How long it takes to freeze depends on your freezer - freeze until completely solid.
No-churn ice cream can naturally take longer to scoop as it doesn't have any additives, but the swirled through Biscoff helps it!
This will last in the freezer for up to a month! (If not longer!)
