That certainly may be part of it! Too many fairies baking. Happening on Raspberry truffles that pouring is now slow too and I used to be able to hit 100 consistently on it, so bet you are right. These are the only two recipes I have left to finish and I was saving them for the baking badges. Didn't know there would be the bake off as well!
Will try tomorrow when more fairies are in school!
