Frequently asked questions

What different kinds of crust can I use?

Shortbread crust is a homemade delicacy that is easy to make and makes your lemon bars seem like they came from an expensive bakery. All you need for this recipe is flour, powdered sugar, butter, salt, and baking powder.

For this easy lemon bars recipe, you can also use a prepared graham cracker or cookie crust. A refrigerated crust is also a good crust for this dessert. You could also try this easy Amish pie crust recipe with just a few ingredients.

How can I cut my lemon bars cleanly?

To get those nice clean lemon squares like the ones you see in the bakery, keep a bowl of hot water next to you while you are cutting. Dip your knife in the water and wipe it clean before and after each slice.

Can I make these in the instant pot?

Yes, you can make these in an instant pot but you will need to find a cake pan that fits. It is also best to have a trivet and a sling to easier remove the pan afterward. Cover the pan with foil to keep out the condensation and pressure cook for 20 minutes. Let the pressure release naturally and move the pan to a wire rack to cool. 

How do I zest a lemon?

You can zest a lemon using a grater or a lemon zester. First, rinse the lemons in warm water to make sure you get all the wax off. Then, just rub the lemon gently across the grater or zester. Avoid the white parts. They are very bitter.

How to store leftovers:

  • Store: Put your leftovers in plastic wrap in an airtight container in your fridge for three to four days.
  • Freeze: To freeze leftovers, wrap in plastic and put them in a freezer bag. They will be safe in the freezer for three or four months.
  • Thaw: Don’t forget to take them out of the freezer the night before serving. Defrost overnight in the fridge for best results.

Cooking tips:

  • Let ingredients come to room temperature before using them for best results.
  • Your bars are done when the edges start turning light golden brown and the center is jiggly but not watery.
  • If you have a glass baking dish that fits in your air fryer, that is perfect because some metal pans can leave a metallic flavor.
  • You can use other flavors of juice for those who don’t like lemon. Try orange or lime juice.
  • Spray the pan with oil to keep the parchment paper from sliding around or sticking.
  • Use the bottom of a heavy glass to flatten the pie crust out. 
  • Use the juice from fresh lemons for a fresher flavor.

As someone that doesn’t eat a lot of sugary foods, these are super sweet! That being said, they were delicious. We topped them with some chopped strawberries for extra zing. If using a tray air fryer vs. the bucket style, make sure to put the pan on the bottom rung. It was fun watching the filling spin in circles, but I had to cook it 5 extra minutes after I moved it to the bottom rung.
