Did you go a little overboard buying Girl Scout cookies this year? No judgement here; I know how easy it is to get carried away when you see those boxes stacked on a table outside your local grocery store. (Not to mention the cute kids selling them!)
And while they're great on their own, there's only so many cookies you can eat before you start to wonder why you bought seven boxes of the same kind. If you've got a surplus of Thin Mints in your pantry, you're going to want to make this milkshake.
