Soak the Dates : Place the pitted dates in a bowl and cover with hot water. Let soak for 60 minutes to soften. Drain well.
Add Ingredients to Blender : Add the soaked dates, full-fat coconut milk, vanilla, cinnamon, and a heavy pinch of salt to a high-speed blender.
Blend Until Smooth : Blend until completely smooth and creamy, stopping to scrape down the sides as needed. The sauce should be thick and glossy.
Adjust & Serve : If needed, add 1–2 teaspoons of warm water to thin. Serve immediately or store in an airtight container in the fridge.
