I usually vape it after 3 days. Flavor doesnt change a hole lot, the cookie sets in slightly.. for more cookie you can add .5% FA butterscotch and decrease vienna creme to .5%
This one surprised me. Looked at the description, looked at the flavors and thought, "Hmmmm...................". Welp, waited for a week, and sure enough NAILED the Golden Oreo alright. As written, was dead on accurate. May try a 2nd batch with your butterscotch sub and see what it does to the cookie.
@Zvapez85, I'm NOT the author, but having tried this out, and the fact that it's a very low percentage of flavors, probably best NOT to sub that, if you want the true effect as written. Just my .02.
