You Need: A Whisk
Sub In: Two Forks
A whisk introduces air as you're blending ingredients.

You can do this with a fork, too; it will just take longer for your mixture to get fluffy. Even better, place two forks so their tines interwine, tape their handles together, and whisk away. The space between the forks helps add air.
Tip: Don't use this makeshift whisk on nonstick pans; the forks can damage the lining.
