Lemon Bars are some of my favorite desserts, and this recipe is perfect. It’s balanced, not overly sweet, and has just the right amount of tartness. If you want a delectable dessert for a bake sale or special occasion, these just scream Spring!

I have made this lemon bar recipe several times, and it never disappoints. I don’t limit it to a party or celebration—sometimes, I make them to satisfy a craving! My husband and kids love them, too. So, I have to make sure I get one as soon as they’re ready because they disappear fast.

Why You’ll Love These Lemon Bars

  • You only need 6 ingredients. This recipe calls for just 6 ingredients! That’s in total between both the crust and the lemon filling. They are also simple ingredients, so you don’t have to worry about hunting down an obscure ingredient. It’s a bold dessert with minimal components.
  • They’re budget-friendly. The cost to make these lemon bars is low, too. You don’t have to spend a fortune to make amazing recipes at home, and this one proves it! The ingredients used are mostly staples like flour and sugar which are typically inexpensive.
  • You can prepare the components in advance. I like to bake the crust ahead of time so I only have to worry about the filling. This is especially helpful if I’m making an extra batch or for a specific occasion. It cuts the total time in half!

What You’ll Need

Below are all of the items you’ll need to make the homemade buttery shortbread crust and the homemade lemon filling. Scroll down to the recipe card for exact measurements.

For the shortbread crust

  • Flour: This is the base ingredient for shortbread. I use all-purpose flour for this recipe but you may try your favorite gluten-free blend instead.
  • Sugar: I use granulated white sugar to sweeten the crust. I keep it perfectly simple here to let the filling shine.
  • Salt: I add a pinch of salt to balance the sweetness and bring out the rich flavors of the butter.
  • Butter: This is what will hold the ingredients of the crust together and help it become perfectly golden as it bakes. I like unsalted for this recipe.

For the lemon filling

  • Large Eggs: This is key to making a rich and stable filling for the lemon bars. They provide structure so everything holds together for a perfectly gooey result.
  • Sugar: I use more granulated sugar here because the lemon filling will be baked into the crust. 
  • Flour: This helps to thicken the filling to the right consistency. You may use cornstarch here if you prefer but I keep it simple so I’m already using flour in the crust.
  • Lemon: I use fresh lemon juice and zest from two large fresh lemons to ensure that the lemon flavor is prominent and bright for the perfect zing.
  • Powdered sugar: This is optional but classic lemon bars have a healthy dusting of powdered sugar on top before serving so I like to keep with tradition and add it to these.

How to Make Lemon Dessert Bars

Preparing and baking these delicious lemon bars is easier than ever! Below are step-by-step instructions to help guide you through the process so the result is an amazing dessert.

  • Prep the oven and baking dish. Preheat your oven to 325 degrees F and line a 9×13 baking dish with parchment paper.
  • Combine the crust ingredients. Add the ingredients for the shortbread crust to a large mixing bowl. Stir the ingredients until they are well mixed but a little crumbly.
  • Bake. Press the crust dough evenly and firmly into the bottom of the baking dish. Bake it for 18-20 minutes or until it starts to brown.
  • Make the filling. While the crust is in the oven, whisk the lemon filling ingredients in a separate mixing bowl. They should be well combined and creamy.
  • Add to the crust and bake. Pour the lemon curd filling immediately over the crust as soon as you take it out of the oven. Bake the lemon bars for an additional 20-25 minutes. The edges should be golden and the middle soft-set.
  • Cool and chill. Allow the lemon bars to cool completely on a wire rack at room temperature. Then, place them in the refrigerator for at least 2 hours to fully set.
  • Slice and serve. Sprinkle powdered sugar on top, slice into squares, and enjoy!

Tips for Success

  • Use a glass dish. These lemon bars bake the best in a glass baking dish. I have tried using a metal pan instead and the crust always comes out too dark. If you want perfectly golden brown shortbread, use the glass instead!
  • Slice chilled. Ensure it is completely cooled before slicing it into bars. If you try slicing while warm, the filling will become soft and gooey. It needs chill time to fully set before you slice into them.
  • Double wrap when freezing. I highly recommend wrapping the lemon bars in plastic wrap and then in aluminum foil if you plan to freeze them. This is a great way to prevent freezer burn. You should do this if you freeze individual squares or the whole dessert.

Proper Storage

Store these lemon bars tightly covered or in an airtight container in the refrigerator for up to 1 week. Cover them or place them into a freezer-safe container and freeze them for up to 4 months. Thaw them in the refrigerator overnight before enjoying them.

    Have made them twice now in glass pan and aluminum pan, each time they turned out different. And each time I had to cook longer and put it on 350!
