The cupcakes are vanilla (recipe here), the icing is plain butter buttercream tinted grassy green, and the flowers are all made from gumpaste. I used a daisy patchwork cutter (see here) to cut the large daisy, and small daisy cutter which I have had for years to do the small ones. I left them to dry in flower forming cups - a recent, and very awesome purchase - so they were slightly curved.
I hope the birthday girl enjoys them as much as I did making them.
Update: Here are the pics of the matching Upsy Daisy cake.
