There are two main differences between a muffin and a cupcake. The most obvious is that cupcakes are generally frosted in some way, but the greater difference lies in the texture. Muffins tend to be more dense, or possible more moist, than cupcakes. Cupcakes are supposed to be a bit lighter, more tender and fluffier than muffins. As Dagmar, at A Cat in the Kitchen, described it “If you threw a cupcake against the wall, you would hear something of a â€œpoof!â€ If you threw a muffin, you would hear a ‘thud!'”
But not all muffins or cupcakes fit into this mold. There are dense cupcakes and light and fluffy muffins. Why not give them their own name to distinguish them from their origins? Fluffin – fluffy + muffin – is a term that works perfectly for both categories and can be applied to each and every cake-like muffin (and muffin-like cupcake) out there. It might take a while to catch on, but the cute factor might just give it a push into popularity.
