I agree. Not a cake or icing or candy (unless chocolate candy) fan but I love love love me some ice cream . And can totally chug a regular shake. My DDs had that cake one after they ran the Disney half marathon so it was their reward. And they oddly chose strawberry which came with a strawberry shortcake type cake. They shared it and a burger and fries. They needed the carbs.
I tried a boozy one at D-Luxe burger and it was disappointingly runny. More like milk. And the CM there said they can't get them any thicker because the booze in it doesn't allow it to be frozen. I bought that line and drank the milky booze drink...ick. But in thinking now...what about mudslides and the such? They are pretty frozen.
