A baked good sold in many NYC delis they have the consistency of a muffin, but the shape of a piece of toast, sometimes lathered with white icing on the top. They come in many different flavors such as chocolate, marble and carrot. Great for a pre drinking snack if you don't have the time to eat a proper dinner, as it will soak up a lot of the alcohol.
"Hey Max, I plan on drinking tonight. I'm going to have a muffin toast, how about you?"
