Zusatztipps für die Zubereitung

Be sure to soften the butter well for both the shortbread and the frosting to achieve the best texture. Pressing the dough evenly into the pan ensures even baking and a uniform crust. Cooling the bars completely before frosting prevents melting and keeps the topping smooth and appealing.

Varianten und Anpassungen

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

Serviervorschläge

These bars pair beautifully with a glass of sparkling Moscato for adults or a cold glass of milk for kids. They are ideal for festive occasions, afternoon tea, or as a charming homemade gift.

Recipe FAQs

How do I ensure the shortbread base is tender?

Use softened unsalted butter and mix it gently with sugar before folding in flour. Avoid over-mixing to keep the base tender and crumbly.

Yes, you can add lemon zest or cocoa powder to the frosting to create different flavor variations that complement the buttery base.

What is the best way to store these bars?

Store bars in an airtight container at room temperature for up to 3 days or refrigerate to keep the frosting firm for longer freshness.

How can I prevent the frosting from melting?

Ensure the shortbread base is completely cooled before spreading the frosting. Refrigerate the bars after frosting to help it set firmly.
