Eureka! I found the perfect frozen hot chocolate for me. I have actually had Serendipity's frozen chocolate. I also have tried Big Train's frozen hot chocolate. These are my two favorite commercially available frozen hot chocolates. I have tried several frozen hot chocolate recipes, but none had the "ice creamy" taste that both of them had and not as "chocolatey" as I would have like. This is even my second version of Frozen Hot Chocolate that I have posted here. My most recent experiment was Mamafoodie.com's version which was very different from other recipes and very satisfying, but for me was almost there. She confessed that she wanted it less chocolatey than Serendipity's. This is my adaptation of her recipe with a few changes of my own. For me, I think the secret ingredient is heavy cream, which now I'm thinking we avoid using in trying to be healthy and are just afraid to go there. In the future, I may try to omit the white chocolate and butter to lessen fat content, and see how that tastes, but for now, I think this is it for me. My search is done. Please note that cooking and prep times do not include the time it takes for the batch to cool to room temperature prior to blending with ice.
