Preheat your oven to 160C Can / 180C and place cupcake cases into your cupcake tin. I sprinkle a little rice into each hole before the case as this helps reduce unwanted moisture.

Cream together your softened butter and sugar using an electric hand whisk. Do so until lighter in colour and fluffier in texture.

Gradually add your eggs (I whisk briefly in between each addition) and mix in.

Sift in your flour, cocoa, baking powder and xanthan gum and then mix with your electric hand whisk until combined.

Spoon your mixture into your cupcake cases and place in the preheated oven for 20-22 minutes.

Remove from the oven and allow to cool very briefly in the tin, then move the cases to a cooling rack.

To make your buttercream, place your butter in a stand mixer (or electric hand whisk if you don't have a stand mixer), mix on its own on a high speed for about 5 minutes. The butter should change from a more yellow colour to being a lot more pale.

Melt your white chocolate (I do this is the microwave), put to one side to cool whilst making the rest of the buttercream.

Add your icing sugar gradually to the butter (I do this in two stages). I mix each addition of icing sugar for around 3-5 minutes before adding the second half.

Now add in your melted, cooled white chocolate mix for a couple of minutes to combine. It should be the right consistency at this point. If you think it's too thick you can add a couple tsp of milk - it needs to be pipable. If too thin you can add more icing sugar.

Dip each of your gluten free 'oreos' into the melted white chocolate and place onto a cooling rack to fully set. I place each biscuit onto a fork above the bowl of melted chocolate and then spoon the chocolate over to coat.

Once set draw on eyes and mouth like a snowman (and a nose if you have the right colour writing icing) and make a triangle out of orange fondant and stick it to the face using a tiny amount of the buttercream you've already made.

Transfer your white chocolate buttercream into a piping bag you don't need a nozzle just cut a hole (about 2cm) in the bag. Then pipe your buttercream on top. If you'd prefer you can spoon the icing on - just make it look like a snowman's body!

Stick the snowman's head into the buttercream so it's nicely positioned.

Sprinkle over some desiccated coconut if you wish so it looks a bit like more snow flakes. And add some colourful sprinkles for the snowman's buttons. Repeat till you have a gang of snowmen!

Enjoy!
