This went WAY better than expected! I had a Spanish Hot Chocolate in October of last year and have been thinking about it ever since, thinking it must be the thickest cream and lots of sugar to be able to do it! I thought today "No, I've got to try it myself", so I found this recipe and was shocked by how easy it was and how minimal the ingredients were! It took about 5 minutes and I had a delicious dessert to dip some cookies in or enjoy by itself, absolutely delicious! I'll be sending this recipe around for sure.
(Also if you add a little more cornstarch, I can imagine it'll be more like chocolate pudding. I also used potato flour instead of cornstarch since that's all I had and it worked swimmingly.)
