"So easy to mix up and I actually had all the ingredients on hand. However, I probably wouldn't make them again because I found the chocolate taste of the actual muffin rather bland. They really needed the chocolate chips!. I used top-quality cocoa (Valrhona) and I was surprised by how little the recipe called for. I subbed sour cream for some of the milk as suggested by others. I wonder if a dutch-process cocoa would have had better results"
