Zusatztipps für die Zubereitung

Ensure the butter is softened but not melted to achieve a light, crumbly shortbread texture. Press the dough firmly and evenly to prevent cracks during baking. Cooling the bars fully before frosting helps keep the frosting smooth and prevents melting.

Varianten und Anpassungen

For a fresh lemony twist, add 1 tsp finely grated lemon zest to the shortbread dough. Incorporate white chocolate chips into the dough for an extra layer of richness. Use colored or flavored sprinkles to match the theme of your celebration.
