It's very easy to make. My wife and I do it all the time. Take a normal protein shake and put it in an ice cream maker, takes 25 minutes. My standard recipe is:
3 cups unsweetened almond milk
4 scoops Metabolic Drive protein powered of choice
A few stevia packets
Put in ice cream maker for 25-30 minutes, done, delicious, no carb protein ice cream! Add some raw nuts if you're feeling it.
