Robots are appropriate for any occasion. They are neutral but friendly so you can use this card for birthdays, get well soon, congratulations on your new baby, good luck on your exams, anything!
I'm going to let our fair submitter describe these amazing cakes in her own words!
I made this cakes for my older sister's 20th birthday, the robots are made to look like her and her boyfriend of three years. The one on the left is her, with pink strawberry flavour cake with jam and on the left is her boyfriend with chocolate cake and nutella. Both are covered in marzipan with a touch of edible glitter (Oh and the heart at the top is a biscuit with red icing).
Bravo! These are super adorable!
