Cream the butter & sugar until pale and mousse like
Beat in the eggs & vanilla
In a separate bowl combine the flour,baking powder & salt
Add dry ingredients to the butter & eggs, mix gently.
If the mixture is too sticky then add more flour sparingly.
Halve the dough,make into fat discs,wrap each half into clingfilm and rest in fridge for at least 1 hour.
Remove one disc and place onto a floured surface.Roll out to a thickness of ½cm. Cut with the cookie cutters & place onto greased or lined baking sheet leaving a small space between each one.
Bake the cookies for 8-12 minutes until light golden around the edges
Cool on a rack
For the icing mix hot water with the icing sugar, very slowly, mix to form a thick paste. Colour as desired
Decorate the biscuits with the icing. I then used ready prepared writing icing to decorate the butterflies in more detail
