Probably because muffins are just about the pinnacle of baked goods. They can be made in a multitude of delicious flavors (blueberry, banana, cranberry, corn, etc.), they are highly transportable, long lasting, are packable and stackable, make great impromptu gifts, and bring warmth and gladness to the heart. In Equestria, they could also be infused with all manner of magical and healing properties. No other baked good can approach their simultaneous delightfulness and utility. Perhaps a better question would be why wouldn't Derpy like muffins.

Would Muffin Empress Derpy use different silos for different flavors of muffins as well, or would she uniformly distribute them as a 'not all eggs in one basket' strategy?
