Drive-Thru comparable milk shake

We make these all summer long.

2 cups ice water + 1 1/2 cups powdered milk OR 3 1/2 cups milk of choice (almond/soy/rice/coconut+water/cow/cashew etc)
1/2-2/3 cup honey/sugar/agave
1/4-1/2 cup unsweetened cocoa
1-2 tsp vanilla (or I often throw in a vanilla bean)
Fill rest of blender full of ice
2 TBS olive oil or other pourable oil
1 tsp emulsifier-liquid lecithin OR 5 second spray of non-stick spray (I learned this trick from another recipe and it makes all the difference in the world)

Place ingredients in your blender and blend until smooth. I have both a Vitamix and Blendtec. If you find that your motor on your blender is struggling, you'll need to add more water and have a less thick shake. I often add a bananaor peanut butter. You can also leave out the chocolate and add more vanilla. ENJOY! We *LOVE* this recipe and use it all summer long!
