Sorry moonpoodle, this recipe just doesn't seem to work. I followed exactly with not very eatible results. The batter was pretty much dough, I had to stir the candy in with my hands. I went with it anyway placing a scoop in each baking cup and while it was baking I thought it was going to work, but as soon as I took them out of the oven the centers sunk right in. I ened up with what tasted like shortbread with really chewy caramel in the center. After they cooled they became hard as rocks and I had to toss them. I'm not sure if there is something missing from the recipe, but these did not turn out anything like the picture indicates.
Ok, I'm going to start by saying that the reason this recipe just did NOT turn out may be that I didn't give it the benefit of the doubt. I followed the directions exactly, but the batter that resulted had the thickness and consistency of cookie dough, not traditional cupcake batter. I truly did not see a way that it could possibly work, since it was such a thick batter and didn't look like it would even "accept" the candy pieces. Assuming that an ingredient had been inadvertently left out of the published recipe, I ended up adding some milk, which appeared to solve the problem. However, the cupcakes took far longer to bake than the stated 20 minutes. When they finally appeared "done," they were all sunken in and had a too-delicate texture. Maybe the milk was not missing after all (or maybe an egg should have been added instead?), and I had made the batter just too thin. I don't know. These are also WAY, WAY too sweet. I, my fiance and our roommate all found them to be far too sugary -- and I had even omitted adding the frosting and topping! My fiance, who is a very good cook in his own right, was of the opinion that there was also too much butter flavor to the cake part. So... regardless of what I may or may not have done wrong -- or if there are any missing ingredients -- if I were to make these cupcakes again I would easily cut the sugar in half. The candies add more than enough sweetness on their own. What I *do* know is that this recipe took a long while to make, given the time needed to chop a lot of very sticky candy bars. Between the time factor and the expense -- butter and the candy not exactly being low-cost ingredients -- I will not be making these again unless and until some other cook can tell me what I did wrong.
