The biscuits were distinctly more chocolaty than the others and held their own when dunked into a freshly poured cup of tea. When they are made with custard powder they are known as “yo-yos” – this is more localised to Melbourne.

Transfer the biscuits onto a baking tray lined with baking paper or a silicone mat and bake for 10-11 mins until the biscuits are firm and starting to go golden on the edges. In the bowl of an electric mixer add the butter and sugar and mix on a medium speed for 5 minutes until the butter is light and creamy.

When we've worked our way through all those custard creams I'll be putting the tin to good use storing my sewing supplies or felty works in progress. The recipe from the Women’s Weekly “Best Ever Recipes” cookbook published back in the 1970’s or 1980’s which, to this day, is still my all time favourite cookbook. It also fared well after going for a dip in the obligatory cup of tea - becoming soft but also having enough strength to hold itself together. Custard Creams are also excellent dippers and to be frank, there’s very little that brings me more comfort than a cup of tea and a couple of (9) biscuits.

Cream butter – Place butter in a bowl and beat with an electric mixer on medium high for 1 minute until smooth and fluffy.That’s a fact, 9 out of 10 Brits actually voted the humble Custard Cream to be their favourite biscuit. When you’re ready to eat them, transfer them to a wire rack or plate and let them sit at room temperature for an hour or two until fully thawed. Once the eggs are fully incorporated add half of the flour and mix to combine, add the milk, custard powder and vanilla extract followed by the remaining flour and mix again. Treats such as Gingernuts, Bourbon Biscuits, Party Rings and Hob Nobs are almost always accidentally vegan. If they’re dark or really thin they can conduct heat more quickly and melt the butter too fast so the cookies melt before they have a chance to cook.

Icing Sugar (Confectioner's Sugar - US): Used for its very fine texture and because it dissolves without leaving any grain. I thought it may have been heat related so chilled the second half of the balls for 20 minutes and same result. Pureicing sugar (packet labelled as such) is made with 100% sugar only and is used for icing that sets hard, like royal icing.The powder is activated when liquid is added, producing carbon dioxide and forming bubbles that cause the mixture to expand. Leave to completely cool before spreading the buttercream and sandwiching the biscuits together otherwise they might break.
