Why these Lemon Bars are Best

All lemon bars are NOT created equal. If you’re here looking for the secret to the best lemon bars, you’ve come to the right place.

For years I have tried DOZENS of lemon bar recipes, and they all vary in consistency and taste, tart, sweetness, moisture and dryness.

What I love most about a lemon bar, is a buttery shortbread cookie crust with a sweet, tart lemon topping. I’m open to glazes and powdered sugar.

Today’s recipe has been made in my kitchen at least a dozen times over the past year.

  • Buttery shortbread crust
  • Sweet and tangy lemon topping
  • Powdered sugar for a touch of sweetness to finish

Today’s bars have the perfect consistency. Thick lemon filling on top of a buttery shortbread cookie crust.

Only 7 Ingredients

Ingredients needed to make lemon bars.

You only need seven ingredients to make today’s lemon bars.

  • Lemon: It all starts with fresh lemons. DO NOT use bottled juice here. You’ll want to use the lemon zest too. Not sure how? Check out my tips and tricks on how to zest a lemon.
  • Butter: Margarine and lard will not work here. You need real butter for the most flavorful crust.
  • Flour: Used in both the crust and the filling, it gives structure to these bars. You can swap it out for King Arthur Measure for Measure to make these bars gluten free!
  • Powdered Sugar: sweetens the bars without a grainy texture.
  • Eggs: provides the fluffy texture in the lemon topping.

How to make Lemon Bars

Step by step photos showing how to make lemon bar crust.

Make the Crust:

  • Mixture may be crumbly. Use your hands or a pastry blender.
  • Press into bottom of prepared baking dish.

PRO TIP: Use a glass pan if possible. I find the flavor is best, and the citrus doesn’t interact with the metal pan! But a metal pan will still work!

Make the Filling:

While crust is baking, make the lemon filling. Use our guide on how to zest a lemon for best tips and tricks.

Pour filling over par-baked crust. Bake until edges are golden brown. DO NOT overbake.

Lemon bars cut into squares and topped with powdered sugar.

Top with icing and powdered sugar. The best of both worlds.

When chilled, remove from pan by lifting the foil (or parchment) and cut into squares. Sprinkle with powdered sugar and enjoy!

  • Line an 8 x 8 inch (or 9″ square pan) with foil or parchment paper. Set aside.
  • Preheat oven to 350 degrees F.
  • In a large mixing bowl, cut together the cold butter, all-purpose flour, and powdered sugar. Mixture may be crumbly. Press into bottom of prepared baking dish.
  • Bake crust in oven for about 15 minutes. 
  • While crust is baking, make the lemon filling. Combine granulated sugar, flour, baking powder, eggs, lemon juice, and lemon zest.
  • Remove crust from oven and immediately pour mixture over the baked crust. Return baking pan to oven for an additional 20 minutes, or until edges are golden brown.
  • Remove bars from oven. To make glaze, whisk together powdered sugar with lemon juice. Drizzle over warm bars. Cool completely then refrigerate for about 2 hours.
  • When chilled, remove from pan by lifting the foil (or parchment) and cut into squares. Sprinkle with powdered sugar and enjoy!


  • Use real lemons for the lemon juice. Bottle lemon juice doesn’t have the same fresh flavor!
  • Chill your lemon bars. For best results, lemon bars have an enhanced lemon flavor when chilled, plus it let’s them firm up some so they are easier to cut.
  • Speaking of cutting, the filling in lemon bars can be a little finicky when cutting. If you want PERFECT lemon squares, pop the bars in the freezer for half an hour before slicing.
  • Help! My powdered sugar has absorbed into my lemon bars. No fear. This happens. First, wait until the bars have cooled and chilled before adding your powdered sugar. It’s best to sprinkle generously right before serving. But, if it absorbs again, just add more powdered sugar, you can’t go wrong!

    1. They get a little soft and gooey in the freezer. It’s possible, but they don’t have the best texture after thawing,.

    1. Yes! I’ve done it several times! My only suggestion would be NOT to double the glaze. The original recipes makes a sufficient amount to cover the 13×9. Just double the bars part 🙂
