I just made 2 batches of heart shaped NFSC, and now that there cooling off I see pimples all over them. ( Pimples= looks like the cookies have goosebumps.) I don't know why that happened. My oven was hot enough. So was the cooking time. The cookies taste great and are done. Will icing the cookies hide that? I been making the cookies for at least 4 years now and I seen it before, but today they stand out.
Are they air bubbles? If so, this is what I do.. I know it sounds crazy, but it works! As soon as they come out of the oven, I press my Wilton cookie spatula down on all of them (while they are hot) and that gets rid of the bubbles. In most cases though, the icing will cover them.
Thanks I'm baking today so I'll try that and let you know the outcome.
I was going to suggest the spatula technique too. For perfect smoothness, gotta use something perfectly smooth and flat, like the bottom of a class or a container.
