Recipe FAQ
What is lemon bar crust made of?
Classic lemon bar crust is usually made with butter, flour, and sugar that’s mixed to a crumbly consistency and then baked.
How do I know when lemon bars are done?
Lemon bars should have a consistency like Jello when they’re done. If you shake the pan and the jiggle like firm Jello, they’re ready to take out of the oven.
Do lemon bars need to be refrigerated?
Yes, lemon bars should be refrigerated. They’ll last for about a week in the refrigerator.
Why are my lemon bars gooey?
Lemon bars are actually supposed to be a bit gooey. However, if your bars are so gooey that they don’t hold their shape, then they weren’t cooked long enough. The best way to tell if your bars are ready to come out of the oven is to use the jiggle test. Gently shake the pan, and if your lemon squares jiggle like set Jello, then they’re done.
How do you cut lemon squares cleanly?
Run warm water over a sharp knife, wipe it dry, and then make a smooth, even cut across the lemon square pan.
Can lemon squares be frozen?
Absolutely. They freeze very well and will last for up to 3 months in the freezer.
How to Store Old Fashioned Lemon Squares
Store these lemon squares in the fridge in an airtight container or covered with plastic wrap for up to a week. For longer storage, freeze them in single layers separated by parchment paper in an airtight, freezer-safe container for up to 3 months.
