Id say the only sub u can prolly make would be for the FLV vanilla puddin...u can use FLV Vanilla Custard ~3%. They are similar but I do find flv vanilla pudding to be a bit sweeter.
The vanillas in this recipe work nicely together added to the cookie, the oreo filling, and the pudding. Vanilla bourbon is usually my go to in bakeries/cookies but here it was just a bit too "dark" for me...madagascar along with holy vanilla gave me the vanilla to creamy that i was after.
JF cookies is a really great flavor...its somewhere in between Fa Cookie and cap sugar cookie.. the 1:1 worked nicely for me. Of course with some butter and fw graham cracker to just add something special to that cookie.
LA CCI completed the cookie filling for me...
I LOVE GOLDEN OREOS AND HAVE EATEN PROBABLY TOO MANY OF THEM IN MY LIFE this recipe is pretty darn close...ENJOY!
