Lemon Bars with Shortbread Crust - Sally's Baking Addiction (1)

Today I’m teaching you how to make lemon bars. I love this lemon dessert recipe so much that I published it in my 1st cookbook, Sally’s Baking Addiction. These are thebest lemon bars and I don’t use that statement lightly. After 1 taste, I’m confident you’ll agree. Everyone needs this recipe.

The process is pretty simple and I’m walking you through each step in the video tutorial below.Pick up some fresh citrus and let’s get baking. Spring is in the air!

Video Tutorial: Lemon Bars

These are classic lemon bars featuring a soft butter shortbread crust and a tangy sweet lemon curd filling that’s baked to the perfect consistency. The lemon layer is thick and substantial, not thin or flimsy like most other lemon bar recipes.

Only 7 Ingredients in these Lemon Bars

  1. Butter: Melted butter is the base of the shortbread crust.
  2. Sugar: Sugar sweetens the crust and lemon curd filling layers. Not only this, it works with the eggs to set up the lemon filling. If reduced, the filling will be too wet.
  3. Flour: Flour is also used in both layers. Like sugar, it gives structure to the lemon filling. These days, I add slightly more flour to the shortbread crust compared to my cookbook version. You can get away with 2 cups, but an extra 2 Tablespoons really helps solidify the foundation of the lemon bars.
  4. Vanilla Extract: I use 2 teaspoons of vanilla extract in the shortbread crust. Not many lemon bar recipes call for vanilla extract and I promise you it’s my best kept secret.
  5. Salt: Without salt, the crust would be too sweet.
  6. Eggs: Eggs are most of the structure. Without them, you have lemon soup!
  7. Lemon Juice: I highly recommend using lemon juice squeezed from fresh lemons. You can also use another citrus like blood orange, grapefruit, or lime juice.

How to Make Lemon Bars in 5 Steps

  1. Prepare the crust: Mix all of the shortbread crust ingredients together, then press firmly into a 9×13 inch baking pan. Interested in a smaller batch? See my recipe note.
  2. Pre-bake: Pre-baking the crust guarantees it will hold up under the lemon layer.
  3. Prepare the filling: Whisk all of the filling ingredients together. No cooking on the stove!
  4. Bake: Pour the filling on the warm pre-baked crust, then bake for around 20 minutes or until the center is just about set. I slightly increased the baking temperature from my cookbook version. Either temperatures work, but 325°F is preferred.
  5. Cool:I usually cool the lemon bars for about 1 hour at room temperature, then stick the whole pan in the refrigerator for 1-2 more hours until relatively chilled. They’re wonderful cold and with a dusting of confectioners’ sugar on top!

Prepared in only 2 bowls and a baking pan, clean up is a breeze. These lemon bars win 1st place every time because they’re the perfect balance of tangy and sweet. In fact, I made them for my friend’s baby shower last weekend and they were the first dessert to disappear. And that’s saying a lot considering the competition: homemade chewy fudgy frosted brownies and adorable mini animal cracker cookies. 🙂

2 Guaranteed Tricks to Make the Best Lemon Bars

  1. Use a glass pan. Ceramic is fine, but glass is best. Do not use metal. Ialways detect a slight metallic flavor in the lemon bars when baked in metal pans.
  2. Use fresh juice.Store-bought bottles are convenient, but you miss out on a lot of flavor. You will definitely taste the difference! I have a super old citrus juicer, but I recently purchased this juicer for my mom and she loves it. Highly recommended.

White Air Bubbles on Top of Baked Lemon Bars

Do you notice air bubbles, perhaps even a white layer of air bubbles, on top of your baked lemon bars? That’s completely normal. It’s the air from the eggs rising to the surface. Some batches have it, some don’t. Regardless, the lemon bars taste the same and a dusting of confectioners’ sugar covers it right up!

Description

You only need 7 ingredientsto make these lemon bars. The lemon curd filling is extra thick and creamy and sits on an irresistiblebutter shortbread crust. Always bake lemon bars at a lower temperature to avoid over-baking. See recipe notes for important tips. They’re simply the best lemon bars and are perfect for picnics, bake sales, spring brunches, baby showers, and bridal showers.

Ingredients

Shortbread Crust

  • 1 cup (16 Tbsp; 226g) unsalted butter, melted
  • 1/2 cup (100g) granulated sugar
  • 2 teaspoons pure vanilla extract
  • 1/2 teaspoon salt
  • 2 cups + 2 Tablespoons (265g) all-purpose flour ()

Lemon Filling

  • 2 cups (400g) granulated sugar
  • 6 Tablespoons (46g) all-purpose flour
  • 6 large eggs
  • 1 cup (240ml) lemon juice (about 4 lemons)
  • optional: confectioners’ sugar for dusting

Instructions

  1. Preheat the oven to 325°F (163°C).Line the bottom and sides of a 9×13-inch glass baking pan (do not use metal) with parchment paper, leaving an overhang on the sides to lift the finished bars out (makes cutting easier!). Set aside.
  2. Make the crust: Mix the melted butter, sugar, vanilla extract, and salt together in a medium bowl. Add the flour and stir to completely combine. The dough will be thick. Press firmly into prepared pan, making sure the layer of crust is nice and even. Bake for 20-22 minutes or until the edges are lightly browned. Remove from the oven. Using a fork, poke holes all over the top of the warm crust (not all the way through the crust). A new step I swear by, this helps the filling stick and holds the crust in place. Set aside until step 4.
  3. Make the filling: Sift the sugar and flour together in a large bowl. Whisk in the eggs, then the lemon juice until completely combined.
  4. Pour filling over warm crust. Bake the bars for 22-26 minutes or until the center is relatively set and no longer jiggles. (Give the pan a light tap with an oven mitt to test.) Remove bars from the oven and cool completely at room temperature. I usually cool them for about 2 hours at room temperature, then stick in the refrigerator for 1-2 more hours until pretty chilled. I recommend serving chilled.
  5. Once cool,lift the parchment paper out of the pan using the overhang on the sides. Dust with confectioners’ sugar and cut into squares before serving. For neat squares, wipe the knife clean between each cut. Cover and store leftover lemon bars in the refrigerator for up to 1 week.
  6. Freezing Instructions: Lemon bars can be frozen for up to 3-4 months. Cut the cooled bars (without confectioners’ sugar topping) into squares, then place onto a baking sheet. Freeze for 1 hour. Individually wrap each bar in aluminum foil or plastic wrap and place into a large bag or freezer container to freeze. Thaw in the refrigerator, then dust with confectioners’ sugar before serving.

Notes

  1. Special Tools (affiliate links): 9×13-inch Glass Pan | Glass Mixing Bowls | Silicone Spatula | Silicone Whisk | Juicer | Fine Mesh Sieve
  2. Halve the Recipe: Halve each of the ingredients to yield around 12 squares in a 9-inch square baking pan. Same oven temperature. Bake the crust for 16-18 minutes and the bars for 20 minutes or until the center no longer jiggles.
  3. Sifting: More often than not, the flour doesn’t fully incorporate into the lemon filling unless it’s sifted with the sugar. As directed in the recipe, sift the two together before adding the eggs and lemon juice. I don’t always do this (and didn’t even do it in the video above!) but it’s preferred to avoid any flour lumps. If you have a sifter, it’s worth using. If you forget, it’s not a huge deal. Here is my favorite sifter. You use it again to dust the lemon bars with confectioners’ sugar.
  4. Lemon Juice: For exceptional taste, I highly recommend fresh lemon juice. Here is a wonderful inexpensive juicer if you don’t have one. Or use another fresh-squeezed citrus like grapefruit, blood orange, lime, or regular orange. You can slightly reduce the sugar if using a sweeter citrus. I recommend no less than 1 and 2/3 cup granulated sugar in the filling as it’s needed for structure.
  5. Room Temperature: Bringing the eggs and lemon juice to room temperature helps them mix easier into the flour and sugar. However, I never notice a taste or texture difference when using cold. Room temperature or cold, use whichever!

FAQs

Why do my lemon bars have a crust on top? ›

The thin, crackly, sugar crust that forms on top when these lemon bars bake is one of my favorite things! It is just a result of some of the sugar rising to the top and hardening during the baking process.

Do lemon bars need to be refrigerated after baking? ›

Lemon bars should be stored in an airtight container and refrigerated in order to prevent bacterial growth or foodborne illness. The filling in lemon bars is made with eggs and can become a breeding ground for bacteria if it's kept in the danger zone (between 41 and 153 degrees F).

Why are my lemon bars runny? ›

Underbaking: This is the most common reason for gooey lemon bars. The filling needs enough time to set, which can be tricky since oven temperatures can vary and the visual cues for doneness are subtle. Solution: Bake the bars until the filling is just set and no longer wobbles when you gently shake the pan.

What is lemon bar crust made of? ›

The crust in most lemon bars usually starts with creaming or rubbing softened butter with a mixture of flour and sugar. Instead of softened butter, I prefer to use melted butter. Making the crust with melted butter rather than softened keeps it crisp and perfectly contrasted to the creamy, lemon filling on top.

Why did my lemon bars crack when cooling? ›

Don't Over-Bake.

If you leave them in the oven too long, it can cause your bars to crack.

How do you cut lemon bars without sticking? ›

I have found that a hot, wet, very sharp knife helps quite a bit. Also, make sure the bars are completely chilled before cutting.

Can you Rebake undercooked lemon bars? ›

This will keep them from spreading and becoming sticky. Can you rebake undercooked lemon bars? Results may vary, but it's worth a shot! Throw them back in the oven at the original temperature and rotate every 5 minutes until it appears done.

Why did my lemon bars curdle? ›

If they used much more lemon juice, they'd: have to bake their bars for a long time to set them up, end up with a soggy crust, and. probably have curdled edges, where the hot pan would overcook the edges while waiting for the center to firm up.

Can you freeze lemon bars after baking? ›

Yes, lemon bars freeze beautifully—they are even good frozen! To freeze the bars, let them cool completely and freeze the batch whole, covered tightly with aluminum foil or plastic freezer wrap, for up to three months. (The cut bars can also be frozen in a single layer.)

Why do my lemon bars smell like egg? ›

If your lemon bars have a strong eggy taste/smell, it's likely due to the lemon curd being overbaked. Be sure to take the lemon bars out of the oven as soon as they're done. Your oven may also be running a little hot.

Why did my lemon bars flip upside down? ›

Set a timer for 5 minutes after pulling the crust from the oven to ensure it doesn't cool too much—if the shortbread is allowed to reach room temperature, the uncooked lemon curd will slip off the top and pool in the bottom of the dish, turning your lemon bars upside down (sounds bananas until it happens to you!).

How to tell if lemon bars have gone bad? ›

If you're approaching the expected expiration date, check how the lemon bars smell. If they smell or taste off, you may want to cut your losses.

Why did the crust on my lemon bars rise to the top? ›

On very rare occasions, when making lemon bars, the shortbread may rise to the surface. (I've seen this happen once in 20+ years of making lemon bars.) This happens because the filling has found its way to the bottom of the pan, either through cracks in the crust or gaps at the edges of the pan.

Why did my lemon bars get brown on top? ›

Why are my lemon bars brown on top? Check your oven temperature with an oven thermometer periodically to make sure the settings are correct. If you find that your desserts brown too quickly on the top, bake on a lower rack in your oven to prevent this from happening.

How to keep powdered sugar from melting on lemon bars? ›

To Keep Powdered Sugar from Melting, Add Cornstarch

Powdered sugar already contains cornstarch, and adding a little extra makes your powdered sugar last longer.

How do you fix thick rind on lemons? ›

The easiest way to fix both too much nitrogen and too little phosphorus is to add phosphorus to the soil. This can be done with a phosphorus rich fertilizer or, if you are looking for an organic phosphorus fertilizer, bone meal and rock phosphate, which are both rich in phosphorus.

Can you eat lemon crust? ›

Lemon rind is not only edible, it is packed with citrus flavour and high in vitamin C. It is a popular ingredient in both sweet and savoury dishes, with small quantities making a big difference to the overall taste and aroma of the food.

Why are my lemon skins marked? ›

Windy conditions may have caused developing fruit to rub or scratch against tree branches. These types of scars likely occur only on the surface of the fruit and, generally, do not compromise its quality. Lastly, chemical and equipment damage are sources of citrus fruit scarring that may need consideration.
