For perfectly baked cookies, use a light-colored quality cookie sheet. You want the cookie bottoms to be ever-so-slightly browned, so undercook them just a little bit. Cookie dough can be made in advance and frozen, allowing you to bake cookies quickly whenever you choose!
When my children complain about something I’m serving, I still request they eat a small amount, but I listen to why they don’t like it and make adjustments. I used to serve broccoli with a cheese sauce on top because I know my children love cheese.
