These were fun to bake. I followed a cutting biscuit recipe from Nigella which provided very yummy biscuits, not too crumbly and dry as they sometimes are.
85g of butter
Half a cup of sugar
1 large egg
Half a teaspoon vanilla extract
One and a half cups all purpose flour
Half a teaspoon baking powder.
Cream the butter and sugar, then beat in the egg and vanilla. Sift the flour and baking powder together and then stir into the butter mixture, ensuring they are thoroughly mixed. Form into a fat disc, wrap in cling film and rest in the fridge for at least an hour.
Then roll them out with a pin and cut out the shapes that you want. Then cut out the centres of the shapes in order to make an area for the "glass".
Put some boiled sweets in a baggie and hit them with a rolling pin to break them up (the kids loved this bit!). I used Fox's glacier fruits, I don't know if these are the best, I'd be interested to hear how different sweets worked for other people.
Then bake at 180c for 8 - 12 minutes. Take care not to overcook - I thought that the "glass" hadn't melted, but in fact it was bubbling! They ended up a little burnt, but they were still yummy and the "glass" was easy to eat.
