R ules to follow when making yo-yo's:

1. Licking the beaters is not optional.

2. Smooshing a fork into rounds of dough is expected.


3. One absolutely must observe the puffery process through the glass of an oven window.


4. Though the book instructs otherwise, a healthy dollop of lemon buttercream ought to squish out when you bite into the cookie. Here, the fingers demonstrate the effect your incisors should have upon the frosting.


5. Required: pretend you're Scrooge McDuck and stack your toothsome treats as though they're coins.


NOT PICTURED: Eating a cookie fresh out of the oven, but that's a given...
