You ask Moonflower if she wants an oatmeal cookie.

Moonflower: "Ooh! For realsies?!"

You use Oatmeal Cookie, and give Oatmeal Cookie to Moonflower.

You and Moonflower sit at the table together, and begin to eat.

Moonflower: "Mmmh! M'startin' to change my mind on the tasty thing. Heehee! I like you a lot, Trailblazer!"

You feel stuffed. Phew!
