Tips
Don't overbake - cookies should look slightly underdone when you remove them as they'll continue cooking on the hot pan.
Press the fork gently to avoid flattening the cookies too much while still creating the classic crosshatch pattern.
Reserve some M&Ms for pressing into the tops before baking for extra visual appeal and chocolate in every bite.

FAQ
Can I use regular-sized M&Ms instead of mini?
Yes, but chop them roughly or use fewer as they're larger and may overwhelm the cookie dough.
How do I know when the cookies are done?
Edges should be set and lightly golden while centers still look slightly soft and underbaked.
Can I freeze the baked cookies?
Yes, freeze in airtight container for up to 3 months. Thaw at room temperature before serving.
