# The Mayonnaise Hack That Makes Boxed Cake Mix Worth Eating
Taste of Home recently revealed a kitchen trick that transforms ordinary boxed cake mix into something genuinely delicious: adding mayonnaise. The ingredient seems counterintuitive, yet it delivers results that even skeptical home bakers notice immediately.
Mayonnaise works because it's an emulsion of egg and oil. When stirred into cake batter, it adds fat and moisture that commercial mixes often lack.

This hack sits somewhere between convenience cooking and actual baking. It requires minimal effort, costs pennies, and demands no special equipment or technique. Yet it elevates a 35-cent box into something worth serving to guests.
