FromScratch, I had raves over that cake hen I made the strawberry and the Mimosa. I had to cut them in tiny slices for family, friends, employees, and I think a few patients.
I think I lucked out on the Moscato brand, Bella someting, in an earlier thread. I had a few bottles of other brands too. I tasted each (and I hate wine taste), the one I chose just screamed dessert. I knew immediately that one was it. Mellow, not one bit of bitterness, and the subtle taste was going to be perfect in the background of the cake and frosting.
For the texture, it was perfect for the syrup. I did have a few bubbles.
I have googled cupcakes and listened to LiasPeps, and it looks like they don't convert well to cupcakes.
Try again before you give up on it. Get that brand asti and follow the recipe exactly. I tweaked the filling and frosting, but I left the cake alone. You must be like me. I have to change a recipe and make it mine. But since I was dealing with champagne in the batter for the first time, I'm glad I did.
