tips to make Sunburst Lemon Bars
- Make sure the butter is softened to room temperature for a smooth crust mixture.

FAQs
1. Can I use bottled lemon juice instead of fresh?
While bottled lemon juice can be used in a pinch, fresh lemon juice provides a brighter flavor that enhances the taste of the bars.
2. How do I know when the lemon bars are done baking?
The lemon bars are done when the filling is set and no longer jiggly in the center. A slight golden color around the edges is also a good sign.
3. Can I make these bars ahead of time?
Yes! You can make Sunburst Lemon Bars a day in advance. Just be sure to store them in the refrigerator until you’re ready to serve.
