Dairy-free protein ice cream that isn't gritty

Soy milk + plant protein + a little fat. Soy milk has the most protein of the plant milks, and 2 tablespoons of coconut cream stops plant protein from tasting gritty.

The base

1½ cups unsweetened soy milk
1 scoop pea or soy protein
2 tbsp coconut cream or 1 tbsp nut butter
1–2 tbsp maple or agave
⅛ tsp xanthan gum (optional)

Tips

Blend well and rest 5 minutes before freezing.
Oat milk works but adds little protein.
Check your protein powder is dairy-free; many 'plant' blends are fine, some add milk.
