Prep the dates. If using dates, soak them in warm water for 10 minutes to soften. Drain well.
Blend until smooth. Add coconut milk, water, dates or maple syrup, vanilla, and salt to a blender.
Blend on high for 30–45 seconds until fully smooth and creamy. If you like, blend in cinnamon, cardamom, or a teaspoon of MCT oil for extra body.
Check the texture. For a thicker, more decadent creamer, reduce the water. For a lighter creamer, add a splash more water and blend again.
Taste and adjust. Add a little more sweetener if needed, a tiny pinch more salt to round it out, or more vanilla for aroma.
Strain (optional). If you used dates and want an ultra-smooth finish, pour the creamer through a fine-mesh strainer or nut milk bag.
Bottle it up. Transfer to a clean glass jar or bottle with a tight lid.
Label with the date.
