If you have more of the b/c, Just smooth it good in the bowl with a spatual. Just mash and turn it over. etc. till you see it is nice a smooth. reapply where you need it. let it set and then smooth ever how you finish smoothin. Next time, yes, be sure it looks smooth in your mixing bowl. Don,t beat it wide open. Most of the time, if you b/c cream come up over the blade , then you will get best results. Good Luck. I think you can fix your problem. You can also use hot water spatula, and don,t let it be wet, and smooth around this area also. Some people do spray (my friend does) with warm-hot water and then use the spatual. I have done this also. Lots of ways can get you there.
