Brew your coffee and chill it in the refrigerator for at least 2 hours, or ideally, overnight.
In a high-speed blender, combine the cold coffee, MCT oil, heavy whipping cream, ice, xanthan gum, collagen peptides, liquid stevia (to taste), sugar-free coffee syrup (to taste), and a pinch of pink Himalayan salt.
Blend on high for 30-60 seconds until the mixture is smooth and frothy.
Pour the frothy keto iced coffee into a tall glass and serve immediately.
