Zusatztipps für die Zubereitung

Make sure the butter is fully softened for easy creaming with the sugar. Use parchment paper with an overhang to lift the bars out without breaking. Allow the shortbread to cool completely before frosting to keep the frosting smooth and intact.

Varianten und Anpassungen

For a lemony twist, add 1 tsp finely grated lemon zest to the shortbread base. White chocolate chips can be stirred into the dough before baking for extra richness and texture.

Serviervorschläge

Pair these dessert bars with a glass of sparkling Moscato for a light, celebratory touch. For children or a simple pairing, serve alongside a cold glass of milk.
