I've played around with this a ton and I actually found a lot that worked and made it hard to decide on a set recipe. So I'll share some changes or subs that I also loved, work similar, and/or scratch the same itch.

(OOO) Speckled Flakes Cereal can be swapped for (TFA) Sweet Cereal Flakes @ 2-3%, it's pretty flexible depending how much you want to push the cereal flake influence. 2.3% was my baseline.

(FA) Vanilla Cookie can be swapped for (WF) Crispy Wafer .75-1.25%. I didn't notice much change at all so I stuck in the lower % range.
I recently tried (SSA) Shortbread Cookie as a sub and it changed it quite a bit but I really enjoyed what a Fruity Pebble Shortbread Cookie would taste like. It wasn't as SNVable, took a couple days steep for it to come together.

If you want a less fluffy and thicker vape, drop the (SSA)Creme De La Creme for (FW) Yogurt.
