First, dump an entire thing of vanilla into the cookie batter you are making with your mom.
Now add whatever you want. Even Oregano. That's what I did.
Continue mixing, adding, measuring, and smiling.
Taste the batter and then spit it back into the bowl.
After that, your mom will hide so she can call your dad and tell him to run to Albertson's and get some chocolate chip cookies on his way home for lunch. Then she will say,
"Okay! Let's go upstairs and shower while your cookies are baking!"
Then your dad will come home and take you to get your cookies out of the oven.
Take your cookies out of the oven.
And that's how you do it!
