It's-Just-Peanut-Butter Cookies

This is a COVID-19 stuck-at-home recipe Alton Brown published up on Facebook in his usual humorous fashion. No changes made — or necessary. I might add some chocolate chips if I'm feeling adventurous...

• 120 g light brown sugar (about 1/2 c)
• 120 g granulated white sugar (about 1/2 c)
