Equipment Needed

To make the Lemon Bars, you will need the following equipment. Having the right tools on hand will ensure that the process goes smoothly and efficiently.

  • Mixing Bowls: You will need at least two mixing bowls – one for preparing the crust and another for the lemon filling.
  • Whisk: A whisk is needed to mix the ingredients for the lemon filling to ensure a smooth consistency.
  • Baking Pan: A 9×13-inch baking pan is ideal for this recipe. This size will give you Lemon Bars that have a good balance between the crust and the filling.
  • Parchment Paper: Lining the baking pan with parchment paper will make it easier to lift the bars out of the pan once they’re baked and cooled. This is especially helpful when you want to cut the bars into neat squares.
  • Sifter: A sifter is needed to dust the powdered sugar evenly over the bars. If you don’t have a sifter, you can also use a fine-mesh sieve.
  • Optional: Zester or Microplane: If you don’t already have lemon zest, you’ll need a zester or a microplane to get the zest from the lemons.
  • Optional: Citrus Juicer: A citrus juicer can be helpful for squeezing the juice out of the lemons. If you don’t have a juicer, you can also squeeze the lemons by hand.
  • Optional: Rubber Spatula: A rubber spatula can be useful for spreading the crust mixture evenly in the baking pan and for scraping out every bit of the lemon filling from the bowl.

Now that you have all the equipment ready, you can start making the Lemon Bars. Follow the steps in the preparation and making sections to create this delightful treat. Enjoy!

For the Crust

  • Butter: 1 cup (2 sticks) of unsalted butter, at room temperature. The butter provides richness and helps to create a tender crust.
  • Sugar: 1/2 cup of granulated sugar. This adds sweetness to the crust.
  • Flour: 2 cups of all-purpose flour. This forms the base of the crust.
  • Salt: 1/4 teaspoon of salt. This enhances the flavors in the crust.

For the Lemon Filling

  • Eggs: 4 large eggs. The eggs help to set the filling and give it a custard-like texture.
  • Sugar: 1 1/2 cups of granulated sugar. This balances the tartness of the lemon.
  • Flour: 1/4 cup of all-purpose flour. This helps to thicken the filling.
  • Lemon Zest: Zest of 4 lemons. The zest adds a strong lemon flavor to the filling.
  • Lemon Juice: 2/3 cup of fresh lemon juice. This gives the filling its characteristic tartness. It's best to use fresh lemon juice rather than bottled for the best flavor.
  • Powdered Sugar: For dusting. This adds a touch of sweetness and creates a beautiful finish on the bars.



Preheat your oven to 350°F (175°C) and line a 9x13-inch baking pan with parchment paper. If needed, use a dab of butter to help the paper stick to the pan.

Making the Crust

In a bowl, combine 1 cup of unsalted butter, 1/2 cup of sugar, 2 cups of flour, and 1/4 teaspoon of salt. Mix until it forms a dough. Press this dough evenly into your prepared pan and bake until lightly golden, about 20 minutes.

Making the Lemon Filling

In a separate bowl, whisk together 4 large eggs, 1 1/2 cups of sugar, 1/4 cup of flour, the zest of 4 lemons, and 2/3 cup of fresh lemon juice. Pour this mixture over the hot crust and bake until set, about 20-25 minutes.

Cooling and Serving

Allow the bars to cool completely before cutting into squares. Dust with powdered sugar and serve at room temperature or chilled. Enjoy with a refreshing beverage of your choice.


Before you start making the Lemon Bars, it’s important to prepare in advance to ensure that everything goes smoothly. Here are the steps for preparation:

Preheat the Oven

  • What to do: Preheat the oven to 350°F (175°C).
  • Why: Preheating the oven ensures that it’s at the right temperature when you’re ready to bake the crust and the filling. This is important for achieving the right texture and doneness.

Prepare the Baking Pan

  • What to do: Line a 9×13-inch baking pan with parchment paper.
  • Why: Lining the pan with parchment paper makes it easier to lift the bars out of the pan once they’re baked and cooled. It also makes cleanup easier.
  • Tips:
    • Cut the parchment paper slightly larger than the pan to create an overhang on all sides. This will act as handles that you can use to lift the bars out.
    • If the parchment paper doesn’t stay in place, you can dab a little butter in the corners of the pan before lining it to help the paper stick.

Once your oven is preheated and your baking pan is prepared, you can proceed to make the Lemon Bars. Follow the steps in the making and assembling sections to create this delicious and refreshing treat. Enjoy!

Making the Crust

The crust for the Lemon Bars is a simple shortbread crust that provides a sweet and buttery base for the tart lemon filling. Here’s how to make it:

Mix Ingredients

  • What to do: In a mixing bowl, combine 1 cup of unsalted butter, 1/2 cup of granulated sugar, 2 cups of all-purpose flour, and 1/4 teaspoon of salt.
  • How: Use a mixer or a wooden spoon to mix the ingredients together until they form a dough. The dough should hold together when squeezed but crumble easily.

Bake the Crust

  • What to do: Press the dough into the bottom of your prepared baking pan, making sure to spread it out evenly. Then, bake in your preheated oven until lightly golden.
  • How: Use your fingers or the bottom of a measuring cup to press the dough into the pan. Try to make the crust as even as possible so it bakes evenly. Bake for about 20 minutes, or until the edges are lightly golden. Keep an eye on it to prevent it from over-browning.

Once the crust is baked, it’s time to make the lemon filling while the crust is still hot.

Making the Lemon Filling

The lemon filling for the Lemon Bars is a tangy and refreshing contrast to the sweet crust. Here’s how to make it:

Mix Ingredients

  • What to do: In a mixing bowl, whisk together 4 large eggs, 1 1/2 cups of granulated sugar, 1/4 cup of all-purpose flour, the zest of 4 lemons, and 2/3 cup of fresh lemon juice.
  • How: Use a whisk to mix the ingredients together until well combined. The mixture should be smooth and slightly frothy.

Bake the Filling

  • What to do: Pour the filling over the hot crust and bake until set.
  • How: Carefully pour the filling over the hot crust, making sure to spread it out evenly. Then, return the pan to the oven and bake for about 20-25 minutes, or until the filling is set and no longer jiggles when the pan is gently shaken.

Cooling and Serving

After the Lemon Bars are baked, they need to be cooled before cutting and serving. Here’s how to do it:

Cool the Bars

  • What to do: Allow the bars to cool completely.
  • How: Remove the pan from the oven and place it on a wire rack to cool. The bars should be cooled to room temperature, which can take about 1-2 hours. For best results, you can also chill the bars in the refrigerator for a couple of hours or overnight to make them easier to cut.

Cut and Dust the Bars

  • What to do: Cut the bars into squares and dust with powdered sugar.
  • How: Use a sharp knife to cut the bars into squares or rectangles, depending on your preference. Then, use a sifter or a fine-mesh sieve to dust the tops of the bars with powdered sugar. The powdered sugar not only adds a touch of sweetness but also gives the bars a beautiful, finished look.

  • How: Arrange the Lemon Bars on a serving platter or individual plates. They can be served at room temperature or chilled, depending on your preference. Lemon Bars pair well with a variety of beverages, such as tea, coffee, or a glass of milk. For a summer treat, try serving them with a glass of iced tea or lemonade.

Your Lemon Bars are now ready to be enjoyed! These tangy, sweet treats are sure to be a hit at any gathering. Enjoy!

Tips and Variations

  • Customizing the Lemon Bars: You can add a twist to the classic Lemon Bars by incorporating other flavors. Try adding a teaspoon of fresh thyme leaves to the crust for a hint of herbaceous flavor. Or, sprinkle the top of the bars with toasted coconut flakes for a tropical touch.
  • Making Ahead: Lemon Bars are a great dessert to make ahead of time. They can be stored in the refrigerator for up to a week or in the freezer for up to three months. Just be sure to add the powdered sugar right before serving, as it can dissolve into the bars over time.
  • Storing: Store the Lemon Bars in an airtight container in the refrigerator. If stacking the bars, place a sheet of parchment paper between layers to prevent them from sticking together.
