These cookies need a milk chaser, and that's a good thing. I prefer desserts that demand a cold glass of milk.
By that I mean, rich, dense and chocolatey. For me, there is definitely such a thing as “too sweet” — many commercially made desserts fit this category — but there is no chocolate “too rich.”
The cookies are bittersweet with subtle cinnamon and cayenne pepper. They're okay on their own, but the dulce de leche adds a needed creaminess. I have had the recipe bookmarked for two years, but you shouldn't wait anywhere near that long to make a version of these.
