Coffee Cupcakes with Coffee Buttercream Frosting

I actually made these more than a week ago. But I've just been too lazy in posting them. They are from my 'Primrose Bakery' book and they are good! I have to say, I really do like the recipes in this book. The ones I've tried anyway, of course.

These are dedicated to Sister No.1 who celebrated her birthday a week ago Saturday.

Happy Belated Birthday, Sis! I'm sure you had a blast celebrating in Melbourne!
