This recipe makes about 5 baking trays of buttery lemon flavoured biscuits, and who would not like those? If you have only one baking tray, let the tray cool before placing a new batch of biscuits on it. You can easily make half of the recipe, too.
Using a food processor with a blade, mix all ingredients till they hold together as a ball. You might want to do that in batches if your food processor is small. Wrap in cling wrap and refrigerate for 1 hour.
Preheat oven to 180 C / Gas 4. Grease several baking trays or line with greaseproof paper.
Thinly roll out mixture on a lightly floured work surface and cut out biscuits. Place on the baking tray.
Bake in the preheated oven till light golden, about 8 to 12 minutes, depending on the thickness of the biscuits.
Let cool. In a small bowl stir icing sugar with lemon juice to make a thick icing and spread on biscuits. Decorate with sugar sprinkles and let dry.
