I know people hate TFA Coconut Extra, but I've made a pretty realistic Tennis Biscuit like so:I use INW Biscuit(1%) and TFA Cheesecake (GC) [3%] for Tennis Biscuit.
FW: Sugar Cookie 3%
FA: Cookie 0.75%
TFA: Coconut Extra 0.25%
You can even try it with FLV: Macaroon instead of the Coconut Extra - haven't tried it, but it should work.
