Recipe Help & Answers

What is the best way to achieve a soft shortbread base?

Use softened unsalted butter and avoid overmixing the dough to keep the base tender and crumbly.

How do I prevent the frosting from becoming too runny?

Beat the butter and powdered sugar until creamy, then add milk gradually to maintain a spreadable but firm texture.

Can I substitute the star-shaped sprinkles?

Yes, you can use any decorative sprinkles or edible glitter to suit your preference or the occasion.

Is chilling necessary before cutting the bars?
