These cakes are made using a basic mixture, but are transformed by the original decoration using caramelized sugar spirals, which are not difficult to make.
Preheat the oven to 180°C/350°F/Gas 4. Line the cups of a bun tin (pan) with paper cake cases. Beat the butter with the sugar until light and creamy. Add the lemon rind. Gradually add the eggs in small amounts, beating after each addition.
