Zusatztipps für die Zubereitung

To add a zesty brightness, gently fold in 1 tsp of finely grated lemon zest to the shortbread dough before pressing it into the pan. For a richer variation, try mixing white chocolate chips into the dough. These simple tweaks can elevate the classic flavor and add a personal twist.

Varianten und Anpassungen

This recipe is vegetarian and can be easily customized. Consider swapping the butter for plant-based alternatives to make it vegan if desired (note: adjustments may be needed for texture). The star-shaped sprinkles can be replaced with other festive decorations to suit holidays or themes.
