Ever wondered how whoopie pies go from machine to market? The Science Channel went behind the scenes to see how The Piping Gourmets—a company known for "all natural and GFCO-certified gluten free" desserts—creates the treats.

In the above episode of their "How It's Made" series, large quantities of ingredients are blended together to create a thick chocolate cake mixture, which a nozzle then shoots onto a tray in uniform circles. The baking sheets are loaded into an oven, and the raw batter is baked into tiny cakes. Finally, the pastries are smothered with filling, squished together, and packaged into boxes. Learn more about the process in the video above.
