What is the normal consistency of cupcake batter?

Cupcake batter should have a consistency similar to thick cake batter. It should be smooth and pourable, but not too runny or watery. The consistency should be thick enough to hold its shape when spooned into the cupcake pan, but not so thick that it doesn't spread out evenly when baking. If the batter is too thick, it will make dense, heavy cupcakes. If the batter is too thin, the cupcakes will be light and fluffy, but they may not hold their shape well.
