Her notes:
"These 3 Ultimates were just made for each other, just take my word for it. Caramel butter and milky caramel fudge and honeycomb crumble give the custard a sweet fudgy caramel vibe. The vanilla frosting swirl, well, why not, it tastes good. This has been my adv for a week. I usually have several set ups going, but not this week. Simple, not very creative, but if you like sweet dessert vapes, mix this, it’ll curb your sweet tooth."

The only thing I changed was the sweetener. Lynda used CAP.
