Whenever I make the Vanilla WASC version my cakes have a crunchy top. No other version does this...just vanilla It's not a huge deal on the cakes since they get leveled, but cupcakes are an issue. I thought maybe it was the sugar content so I took a 1/2 cup sugar out and that didn't do it or anything really. I made this recipe for a long time and it seems that in the past 6 months it has done this. Help!
