There's A Genius Hack To Prevent Cookies From Spreading In The Oven

To prevent your cookies from spreading into each other on the pan while they cook, all you need to do is grab a muffin tin to shape your cookies.

Using this method, your cookies will only have space to grow “up,” resulting in round cookies that are full, thick, and tall that won’t spread into each other.
