6-5-13 FAIL. This does not taste anything like a Frosty. It tastes barely better than a protein shake. Maybe I added too much cocoa powder but it was very bitter. I had some left over chocolate sweetened condensed milk on hand that I added to it. I'll drink it cuz I'm thirsty, but not a big fan. Skinny Shake: tastes like a Wendys frosty: 3/4 cup Almond Milk, about 15 ice cubes, 1/2 tsp Vanilla, 1-2 Tbsp unsweetened Cocoa powder, and1/3 of a frozen banana. Blend well.
