Wondering how much batter to use per cupcake? For standard 2½-inch cupcakes, fill cupcake liners with ¼ cup batter or about ⅔ to ¾ of the way full. Avoid adding too much batter, or the cupcakes will overflow the cups as they bake and cause a mess.

How full should cupcake liners be filled?

Cupcake liners should never be completely filled to the top. If you fill them to the top, then the cupcake itself is going to overflow and cause a mess. We recommend filling our baking cups 2/3 full to allow room for your cupcakes to rise.

What happens if I overfill my cupcakes?

If you overfill the liners, there's too much batter and not enough space to climb. The batter can spill over the sides and you'll be left with flat cupcakes. ... You can also bake a test cupcake and see how it turns out before baking the rest.
