We’ve all eaten many lemon bars and I’m sure that many of you have baked them multiple times. The recipe I’m sharing today, however, is my mom’s, and it is spectacular.
These bars were always on Mom’s Christmas baking list but I make them all year long. They are a bright, pretty choice for Easter and the perfect light dessert for spring and summer entertaining.

The Best Lemon Bars
There are a couple of important things that make this recipe for Lemon Bars a little different from most other recipes out there.
Mom’s crust recipe calls for powdered sugar in place of granulated sugar. I did not understand the significance of this seemingly small difference until I grew old and wise and realized I should always trust my mother. It does something magical and wondrous to the texture of the crust that reminds me of delicate, flaky shortbread. I’ll never make them any other way!
I’ve also found that using both the juice and zest from Meyer lemons instead of regular lemons creates the best flavor in the custard filling. They are naturally sweeter, far juicier, and the best choice when available. Thankfully, I’ve been seeing them through most of the year at our local grocery store.
Ingredient Notes
- Shortbread crust: Salted butter, powdered sugar, and all-purpose flour.
- Lemon filling: Eggs, granulated sugar, salt, fresh lemon juice and zest, and all-purpose flour. While Meyer Lemons are always my first choice you can absolutely make these bars with regular lemons and they will be delicious.
Useful Kitchen Equipment
Microplane/Zester: A must have item for zesting citrus and so much more! Use it for grating garlic cloves, ginger root, spices like nutmeg, and Parmesan cheese. You can also use it to create chocolate shavings for decorating desserts.
Citrus Juicer: This handy kitchen tool allows you to easily squeeze every last bit of juice from your lemons and limes while catching all the seeds.
Dusting Wand: This inexpensive tool is best way to neatly sprinkle powedered sugar over recipes like this one. I use it every time I make Lemon Bars, Brioche French Toast, Gingerbread Cake, and everything else I garnish with powdered sugar.
How to Make Easy Lemon Bars
- Shortbread crust: In a large bowl, combine the crust ingredients with an electric mixer until the mixture resembles coarse crumbs.
- Bake the crust: Press the mixture down into an ungreased 13- x 9-inch baking pan. Bake at 350 degrees F until lightly golden brown around the edges.
- Lemon filling: While the base layer is baking, whisk together the filling ingredients in a large bowl.
- Add filling and bake: Pour the lemon filling over the shortbread crust while it is still warm from the oven. Then, bake it until the topping appears to be set and is just beginning to lightly brown.
After baking, there may be some blemishes, bubbles, or brown spots on the top of the lemon filling. This is not an issue at all since the entire thing will be dusted with powdered sugar.
- Cool completely: Allow the bars to cool completely at room temperature.
- Dust with powdered sugar: Sprinkle the top of the cooled Lemon Bars with powdered sugar. This is done easily with a dusting wand.
FAQ and Valerie’s Tips
The sugar in the lemon filling can caramelize and some of it may rise to the surface creating a slightly crispy, granular top layer. If you notice this, don’t be concerned! The last step of sprinkling the top with powdered sugar will disguise it and if anything, it will just add to the wonderful texture of the bars.
The lemon filling will be thin when you pour it over the hot crust, but it should thicken nicely as it bakes. Be sure to follow the directions and add the correct amount of flour to the filling and allow the lemon bars to cool completely at room temperature before slicing. Remember, lemon bars are intended to be gooey so they will not thicken completely.
You don’t need to grease the baking dish as there is an ample amount of butter in the crust. However, the edges where the filling hits the pan can get a little sticky. Just rinse a sharp knife with hot water and run it around the edges of the pan to loosen them. If the knife becomes sticky with filling while slicing the bars, rinse it in hot water in between slices.
Storage Tips
- Packaging: After dusting the cooled bars with powdered sugar, cover the dish tightly with plastic wrap or transfer the Lemon Bars to a separate airtight container. If you need to stack the lemon bars in the container, place parchment paper or wax paper between the layers to prevent sticking.
- Refrigerate: Since the gooey lemon filling contains eggs, it’s best to keep Lemon Bars refrigerated to prevent bacterial growth. If stored properly, they will stay fresh for up to a week.
- Freeze: Allow the bars to cool completely, then slice into squares and flash freeze them in a single layer on a baking sheet until frozen solid. At that point the bars can be wrapped in foil or plastic wrap and placed in a freezer-safe zippered plastic storage bag and frozen for up to 3 months. Thaw the completely in the refrigerator before dusting with powdered sugar and serving.

Just bought a tubof Meyer lemons at Costco and did a google search for Meyer lemon bars. Your website came up, and boy am I glad it did! I made these for us tonight. They were amazing! I think I took them out of the oven too early as they were very gooey, but they tasted wonderful. Thank you for sharing a family favorite! I hope to build up family-tradition recipes as my husband and I are just starting our little family. Maybe this will be one of them. Thank you!
I’m so happy to hear you loved them. It warms my heart to think that my mom’s recipe could become a tradition for your family 🙂 Best of luck to you!
I had EXACTLY the same experience: Tub of Meyer lemons from Costco! Found your recipe! Made them! Thought I took them out of the oven at exactly the right time, but mine were also gooey!! The flavor is great, but any suggestions about how to “fix” them now?!
Thx!
The texture of the lemon layer should be a bit gooey. To set it up more, you would need to add more flour before baking. I hope they still taste good!
Thanks for the advice. I will try that next time. They do still taste great!
I am a huge lemon fan and would love my own lemon tree!! Not sure Oregon is the right environment though!! Lemon bars are my favorite lemon treat hands down. These look delicious!
I’d love for you to come over and share at Finding the Pretty & Delicious Linky Party!

I haven’t had a lemon bar in forever. But they sound so good! I’m sorry I haven’t been around much to be supportive lately – it’s been a heck of a year in my house. I hope you have been well though!
Jen!!! It’s so good to see you back. I’ll pop over and we can chat. Thanks so much for stopping by 🙂
Ahaha, don`t argue with your Mom, right? Since my own mom doesn`t have a lemon bar recipe stashed anyways, I`ll be sure to make these on my own! I just love love lemon flavored desserts!
These bars look so delicious! Wonderful recipe!
I’ve always loved lemon bars, and yes, have eaten quite a few; however, I’ve never made them. My mother never made them so I don’t have a recipe from her; however, now that I have your mom’s recipe, I have one that I’m sure I will love!! Thanks for sharing!
You’ve got to make them MJ! You won’t be sorry.
Really beautiful!
Whoa… so dreamy! Love lemon bars and really wish to make this on my own one day. My son started to get hooked with lemon card. I think both he and I will finish this whole batch easily! 😉
