Start by making the snowflake decorations. Dust a mat or work surface with icing sugar and roll out the fondant
Using a cutter, cut out snowflake shapes and place them on baking or greaseproof paper to dry out and harden
Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4, and line a muffin tin with 12 light blue cupcake cases, or another colour if you can't find light blue. White would work well
Cream together the butter and caster sugar until smooth
Add the eggs, vanilla and coconut, mix them in
Add the flour and mix it in
Divide the mixture between the cupcake cases, then bake for 20 minutes or until they are golden brown. Let them cool completely on a cooling rack
Using a cupcake corer or a knife, make holes in the middle of each cake
Spoon or pipe the marshmallow fluff spread into each hole
Make the buttercream by mixing the ingredients together in a stand mixer or with an electric hand whisk until they are smooth, then put it into a piping bag fitted with a circular nozzle and pipe it onto the cupcakes
Dip the sides of the buttercream in the dessicated coconut, then add the snowflake shape in the centre
