Some of us were also puzzled here when one of our employees suggested the recipe. And then another employee made us a batch of gooey buttercake and OMG, it was SOOOO good! :) So, we gave the recipe a try and the customer response was phenomenal. Definitely one of those flavors most enjoy in a high-VG medium.
So what it is? Think of a rich, buttery shortbread base with a milky, caramel backnote. Drooling yet? You SHOULD BE! Give it a try.
