1. Place all ingredients in your blendtec (I like using the blendtec as opposed to other blenders because I NEVER have any lumps when it's done mixing).
2. Press the smoothie or frozen treat button and you're done!
3. Top with crushed Thin Mints, and if you're feeling really crazy you can top with whipped cream and green sprinkles!
NOTE: You can place the Frosty in the freezer to thicken or until ready to serve!
