Heat oven to 180C/160C fan/gas 4. Lightly rub the butter and flour together with your fingertips until the mixture looks like fresh breadcrumbs.
Mix the sugar and egg together in another in a bowl with a whisk and when it is really well combined and runny add it to the flour mixture.
Add all the other ingredients and squish it together with your hands, keep working the dough until it’s smooth, soft and comes together in one piece.
Roll the dough out on a lightly floured surface with a rolling pin until it is about half a centimetre thick. Cut into shapes. We did 15 rabbit heads, 15 large circles and 30 mini circles.
Place your biscuits on baking sheets lined with baking paper and bake in batches for about 15 mins (or until they are lightly golden at the edges).
Let them cool in the tin for a few minutes before carefully transferring them to a wire rack to cool completely and become crisp.
While the biscuits cool mix enough cold water with the icing sugar to create a thick icing. Place a quarter of the icing in another bowl and add a very small amout of pink gel food colouring. Transfer both the white icing and the pink icing into disposable piping bags and snip off the end to make a very small nozzle on the pink icing and a wider one on the white icing.
Pipe white icing over the small round biscuits and leave to dry. Then pipe white icing to cover all of the large circular biscuits and the rabbit biscuits (be fairly sparing and spread it out with the back of a spoon – it doesn’t have to be neat on these ones). Once you’ve iced each one sprinkle generously with dessicated coconut before the icing dries.
Take the pink icing and use to create paws on the smaller circles then stick 2 of them onto each of the large circles using icing like glue. With the icing you have left, coat the marshmallows and cover those in coconut too before sticking them onto the middle of the larger circles to create a fluffy tail. Leave to set completely for about 15-20 mins then serve.
