"Esco Bars 6000 Whipp'd tastes just like vanilla gelato with whipped cream or a vanilla milk shake. The cream is very light and sweet, so it’s not heavy or too milky."
If it was me, I would start with the following.....
WF Vanilla Gelato 2%
SSA Whipped Cream 1.5%
INW Shisha Vanilla 1%
FLV Cream 1%
I'd try that first, then tweak as needed and also........
Consider WF Vanilla Cream Extra at 1% in place of FLV Cream.
I would consider adding CAP Milkshake at 2% - 3%, for something that leans more milkshake tasting, if desired. Maybe in place of WF Vanilla Gelato. All depends.
That should get you in the ballpark, per the description. You will likely need to tweak the percentages to taste.
Good luck!!!
