Place all ingredients in a high-speed blender and mix until you have a super creamy consistency.
If necessary, you can add a little more plant-based milk. Ideally, leave the sauce in the fridge to chill for a 1, this will enhance the flavors, but it's not essential.
The dip thickens a bit, but you can add a little milk later if you want it a bit runnier.
Notes
The dip can be stored in the fridge for up to 3 days.
