Place all the ingredients for the sweet cream in a blender and blend until smooth. Add the sweet cream to a resealable container and in the fridge. It will last about 1 week in the fridge.
To the same blender, add the cold brew coffee. With the lid on the blender, turn the blender on and slowly add the collagen peptides through the top of the lid. Then add 1-2 tablespoons of the sweet cream and blend until smooth and frothy.
Add ice to a glass, pour in the sweet cream coffee on top and drink up!
