Homemade frosty

Here's a recipe I saw on pinterest (tweaked a little)... for those times when you need something sweet but don't want to go overboard!

Serving: 2
1 banana
1 scoop chocolate protein powder*
3 T unsweetened cocoa powder
2 1/2 cups almond milk
3 cups of ice
1-2 tsp vanilla

*you need the protein powder to sweeten up this frosty. The cocoa alone won't do it.

If you don't have protein powder, I'm not sure what to add instead. :/ Any other suggestions?

You can change the amounts of ice and almond milk to fit your thickness preference!
