Hi there! I’m Cassandre, and today on Caramel Loafing, I’m sharing a dessert that’s just as lovely to look at as it is to eat: Lemon Bars.

Also known as Lemon Squares, these golden-yellow treats are bright, sweet, and loved by just about everyone. The star here is, of course, the lemon. The top layer is a smooth, custard-like lemon filling—tart yet sweet, soft yet luscious—resting on a crisp, buttery shortbread crust. It’s reminiscent of a classic French lemon tart, but with a much simpler technique.
The contrast between the tangy filling and the melt-in-your-mouth base makes each bite feel like a little love letter. Sweet, tart, tender, and buttery—honestly, it tastes like love ❤️

While most lemon bar recipes follow a similar format, this version puts a little extra focus on texture. The crust is light and crumbly, while the lemon layer is silky-smooth—almost like a citrus pâte de fruit in bar form. We’ve crafted this version to achieve a harmonious bite, where the crust enhances the bright lemony notes without overpowering them. It’s perfect with a cup of hot tea or coffee, and we highly recommend this recipe for all lemon lovers!

How to Make Lemon Bars

  1. Lightly grease an 18x18 cm pan and line it with parchment paper.
  2. Sift the flour and powdered sugar. Using a food processor, pulse the flour, sugar, salt, and frozen butter cubes until the mixture resembles fine crumbs.
  3. Press the crumbly dough evenly into the bottom of the pan. Gently press to level it out—no need to compact it too much.
  4. Preheat oven to 340°F (170°C). Bake the crust for 20–22 minutes or until the edges turn golden and the center shows a hint of color. Adjust timing based on your oven.
  5. While the crust bakes, prepare the lemon filling: Whisk the eggs and sugar together in a mixing bowl until well combined.
  6. Sift in the flour and stir just until no dry streaks remain.
  7. Stir in the lemon juice and let the filling rest while the crust finishes baking. For a smoother texture, you can strain the filling once and remove any surface bubbles using plastic wrap or a paper towel.
  8. Once the crust is baked, remove from oven and pour the lemon filling over the hot crust. Return to the oven and bake at 340°F (170°C) for 10 minutes. Then, loosely cover the pan with foil and bake for an additional 10 minutes (total baking time for filling: 20 minutes).
  9. Let the bars cool completely. Remove from the pan, trim the edges, dust with powdered sugar, and slice into squares or rectangles. Serve and enjoy!
