Notes
This recipe is by Kim Hardesty at LowCarbMaven.com who shares easy keto recipes with a gourmet vibe.Use a high-speed blender capable of blending ice. If your blender isn't able to break up ice chunks, the texture won't be as smooth. Using crushed ice cubes can help if you don't have a good smoothie blender.Make it even healthier! Green vegetables, baby spinach, green juice, or healthy greens can be added for added nutrition.
