Why You’ll Love This Easy Lemon Bars Recipe

  • Double-the-Lemon Bars. These old-fashioned lemon squares have a superior flavor because they’re made with double the lemon juice. If you like your bars extra bright and citrusy, you are going to be head-over-heels for this recipe.
  • The Easiest Recipe. The original Betty Crocker lemon squares with shortbread base call for softened butter that is painstakingly cut into the dry ingredients. My sister Elaine realized that the butter could be melted, then stirred in. Game-changer! It makes the recipe faster, easier, and still yields a fantastic, tender crust! Best lemon bars ever.
  • A Dessert for Lemon Fanatics. Whether it’s Lemon Thumbprint Cookies or Lemon Poppy Seed Muffins, lemon dessert fervor runs strong in my family. When I’m craving something lemony and I want it N-O-W, this easy lemon bars recipe is the answer.

How to Make Lemon Bars

The Ingredients

  • Melted Butter. Not only does melting the butter make these the easiest bars you’ll ever bake, it gives the shortbread crust an extra indulgent, melt-in-your mouth texture.
  • All-Purpose and Whole Wheat Pastry Flour.Use a blend of these two flours and we can all pretend these are “healthy” lemon squares.
  • Powdered Sugar. Key for sweetening the shortbread base and dusting over the finished bars.
  • Granulated Sugar. Adds sweetness to the tart lemon layer and also adds moisture so the bars don’t crack.
  • Lemon Juice. Gives these bars their bright lemon flavor. If you’d like to experiment with other citrus fruits, try Key limes, navel oranges, tangerines, or pink grapefruit (use a bit less, as grapefruit is more bitter than lemon).
  • Lemon Zest. Takes the lemon punch of these sunny bars to the next level.
  • Eggs. Gives the lemon layer its rich, creamy texture and consistency.
  • Baking Powder and Salt. Helps the bars puff a little while baking and balances their sweetness.

Recipe Tips and Tricks

  • Fully Bake the Shortbread Base. This is more important than you might think! If you don’t bake it long enough, it can cause the filling to lose moisture and absorb into the crust.
  • Don’t Try to Cut Back on the Sugar. I’m usually all for trying to reduce sugar in recipes. Unfortunately this is one where the sugar needs to stay, not just for flavor, but also for achieving the right texture.
  • Know When They’re Done. You’ll know when this lemon bars recipe is fully set when no indentation remains when you touch the center with your finger. (Your kitchen will also smell incredible.)
  • Don’t Over-Bake. If you leave them in the oven too long, it can cause your bars to crack. The surface of your lemon bars should have small bubble holes, but not large cracks.

Ingredients

  • 1/2 cup unsalted butter (1 stick)
  • 1/2 cup all-purpose flour
  • 1/2 cup whole wheat pastry flour or additional all-purpose flour
  • 1/4 cup powdered sugar plus additional for serving
  • 1/4 teaspoon kosher salt plus 1/8 teaspoon, divided
  • 1 cup granulated sugar
  • 2 teaspoons lemon zest about three-quarters of 1 large lemon
  • 2 largeeggs at room temperature
  • 1/4 cup freshly squeezed lemon juice from about 1 large lemon
  • 1/2 teaspoon baking powder

Instructions

  • Place a rack in the center of your oven and preheat the oven to 350 degrees F. Line an 8×8-inch pan with parchment paper and set aside.

  • In a small microwave-safe bowl, melt the butter. In a medium mixing bowl, stir together the all-purpose flour, whole wheat pastry flour, 1/4 cup powdered sugar, and 1/8 teaspoon kosher salt. Pour the butter over the top and stir to combine. The batter will be very wet.Press into an even layer in the prepared pan, building the crust 1/2 inch up the sides all around. Bake the crust for 15 to 20 minutes, until barely light brown. Leave the oven at 350 degrees F.

  • While the crust bakes, in a large mixing bowl or the bowl of a stand mixer fitted with the paddle attachment, rub the granulated sugar and lemon zest together with your fingers until moist and fragrant. Add the eggs, lemon juice, baking powder, and remaining 1/4 teaspoon salt. With an electric mixer, beat on high speed until light and well blended, about 3 minutes. Pour into the hot crust (no need for it to cool).

  • Return to the pan to the oven and bake 25 to 30 minutes, until the bars are set, no indentation remains when you touch the center with your finger, and your kitchen smells incredible. Let cool completely, then dust with powdered sugar. Cut into squares and serve.

FAQs

What is lemon bar filling made of? ›

Lemon filling: Mix lemon zest and sugar in a mixing bowl. Add the lemon juice, flour, baking powder, and eggs. Mix until well combined and the sugar is dissolved. Pour mixture over the baked crust.

Why did my lemon bars fall apart? ›

There are a couple of things that can impact the integrity of your lemon bars. The first is if your crust has cracks in it and the lemon curd fills in the cracks. This can cause your lemon bar to break! It may also break if you don't bake the crust long enough or the lemon layer is underbaked.

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 did the top of my lemon bars crack? ›

Don't Over-Bake.

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

What is lemon filling made of? ›

Lemon curd is a spread made out of fresh lemon juice, eggs, sugar, zest, and butter. The eggs in the recipe thicken the mixture, giving it a custard-like consistency.

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

To Keep Powdered Sugar from Melting, Add Cornstarch

So go slow and be conservative with the amount of cornstarch you add. A good rule of thumb is 1 teaspoon of cornstarch for every 1/4 cup of powdered sugar used.

Why did my lemon bars get brown on top? ›

If your lemon bars are brown on top, you cooked them too long. To avoid burning and turning brown, remove the bars from the oven sooner, right when the filling is firm.

What to do if lemon bars won't set? ›

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.

Why did my lemon bars turn 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!).

Why are my lemon bars foamy on top? ›

It is the air bubbles created from whisking the eggs rising to the surface during baking. Lemon bars taste the same with or without that layer and a dusting of icing sugar covers it right up!

Is it OK to freeze lemon bars? ›

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.)

How do you cut lemon bars cleanly? ›

Dusting the knife with powdered sugar before cutting lemon bars can help to reduce sticking and create cleaner cuts. However, this is optional and depends on personal preference. If you prefer a more polished appearance on the bars, you can lightly dust the knife before each cut.

Why do my lemon bars smell eggy? ›

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 is there a crust on my lemon bars? ›

A thin crust on top of lemon bars is a common feature and is usually formed as a result of the baking process.

Why did my lemon bars curdle? ›

Remove your lemon bars from the oven before they turn brown on top. Browning means they're over-cooked, and the custard mixture can curdle.

What is lemon pie filling made of? ›

To make the filling: Whisk 1 cup sugar, flour, cornstarch, and salt together in a medium saucepan; stir in water, lemon juice, and lemon zest. Cook over medium-high heat, stirring frequently, until mixture comes to a boil. Stir in butter.

What is the inside of a lemon slice? ›

It is generally divided into segments that contain elongated cells where water, carbohydrates, and citric acid accumulate, known as the juice sacs. Each slice contains hundreds of sacs, and occasionally there may be a seed.

What's a lemon drop made of? ›

A lemon drop co*cktail is simple to make at home. I like to use lemon vodka, triple sec orange liqueur, lemon juice (fresh squeezed), and lemonade for built in sweetness! Give it a shake with crushed ice, strain into a sugar rimmed martini glass, and enjoy!

What are lemon cakes made of? ›

Very basic ingredients including a base of creamed butter + sugar, eggs, lemon, milk, and flour. We left out the brown sugar and replaced with more granulated sugar. No rhyme or reason here—just didn't feel like reaching for both types of sugar this time. Between the cake and frosting, you'll need 2-3 lemons.
