I've owned this book now for almost 2 years and I can safely say it's the cupcake book I use most out of my extensive collection - so much so that the pages are stuck together with cake batter and buttercream! I have tried lots of recipes from this book including carrot cake, vanilla, chocolate, raspberry & white chocolate, coconut & lime, strawberry & cream, orange, lemon and amaretto to name just a few that come to mind. I have been told many times that the carrot cake cupcakes are the best people have ever tasted.
I read previous reviews about dense or heavy sponge and to a certain extent I agree. There seems to be a bit of a battle between The Hummingbird Bakery Cookbook
and this one. I own both books and as far as I can see the main difference between them is that the Primrose Bakery book uses the creaming method (and no baking powder) to make the mixture rise whereas the Hummingbird bakery favour the all in one method (using baking powder). I think the omission of baking powder is the reason the primrose Bakery's cakes are slightly heavy, so all I do is add 1 teaspoon of baking powder to the mix and the cakes are perfect. I bake, on average, 2 batches of cupcakes from this book every fortnight to take into work and have always had favourable reports and they certainly disappear very quickly.
Another tip I would give is that the icing amounts are very generous so if you are just spreading the icing with a knife you will probably have enough if you halve the mixture. I ice the buttercream with an icing bag and nozzle for a more professional finish. This uses more buttercream but even so I still have some buttercream left over. I have found that the more you use this book, the more comfortable you become with the recipes and you can tweak them to your own tastes. All in all, this is one book I reach for time and again in the kitchen.
