Add liquids first: Pour coconut or heavy cream and almond milk into the blender. This helps the blades catch everything smoothly.
Add the rest: Toss in berries, nut butter, chia or flax, protein powder (if using), vanilla, sea salt, sweetener, and ice.
Blend until smooth: Start low, then increase speed. Blend 30–60 seconds, scraping down the sides if needed.
Adjust texture: Add more ice for thickness or a splash of almond milk to thin it out.
Taste and tweak: If you want it sweeter, add a little more low-carb sweetener and blend again.
Serve immediately: Pour into a chilled glass and enjoy right away for the best texture.
