Ingredients for the Best Lemon Bars

You will need a few basic baking ingredients to make these bars along with a few fresh lemons. Here is what you will need to make this delicious recipe:

Crust:

  • Sugar: just regular granulated white sugar
  • Unsalted Butter: needs to be softened to room temperature
  • Flour: all purpose flour is all you need
  • Salt: cuts through the sweetness and tartness and enhances all the flavors
  • Lemon Juice: the juice of about 1 lemon

Filling:

  • Eggs: creates the richness and creaminess of the filling
  • Sugar: adds sweetness and balances the tartness of the lemons
  • Flour: helps thicken the filling and gives it structure
  • Salt: enhances all the flavors
  • Lemon Juice: fresh lemon juice is preferred and you’ll need 3-4 large lemons
  • Lemon Zest: you’ll need the zest from about 1 lemon
  • Powdered Sugar: used for garnish to balance out the tartness and to make the bars look extra pretty

The measurements for each ingredient can be found in the recipe card at the end of this post. BONUS: If you want a gluten free lemon bar, check out our gf lemon bar recipe.

How to Make Lemon Bars

There are two parts to this recipe – the crust and the filling. Both parts are super simple! Here are the steps:

Crust:

Start by creaming 2 sticks of softened butter and sugar in a large bowl with a hand mixer or stand mixer fitted with the paddle attachment. This will be the base of your really tender crust. Then you’ll add the flour and sugar to bring it all together to form a dough.

The dough will likely be a little crumbly at this point so add in a bit of lemon juice until it starts to come together, form a ball and pull away from the sides of the bowl.

Press the dough into a prepared baking dish lined with parchment paper and bake by itself for 15-20 minutes, or until it’s golden brown.

Filling:

Whisk all of the ingredients together in a large bowl. The mixture will be very runny, but don’t worry it will thicken up as it bakes.

Pour the lemon filling mixture over the baked crust, and then stick it in the oven to bake for another 30-35 minutes. Give the dish a little jiggle and the lemon filling shouldn’t move if it is fully baked.

Let the lemon bars cool completely to room temperature, and then dust with powdered sugar and cut them into squares to serve.

These instructions can also be found in the recipe card down at the end of the post. You can also save or print the recipe there.

Are Lemon Bars Supposed to Be Gooey?

The lemon layer of lemon bars are essentially a lemon curd baked on top of the shortbread crust. They will be soft and somewhat gooey.

To avoid them being too gooey make sure you allow them to set completely when you take them out of the oven. You know when lemon bars are done when you move the pan a bit and they don’t jiggle.

You should cut the lemon bars when they are completely cool. Even better if you allow them to set up in the refrigerator for a couple hours!

Can I Make Lemon Bars in a Muffin Pan?

You can use a muffin tin to make lemon bars, just make sure you only bake them for 12-15 minutes after baking the crust (which you can bake for around 8-10 minutes) as they can overcook.

How Should Lemon Bars Be Stored?

Once you’re done serving (and somehow have leftovers!) you can store your lemon bars either in the refrigerator or in the freezer.

Store in the refrigerator by placing the lemon bars in an airtight container using parchment or wax paper to separate layers if you have more than one. They will stay fresh for up to 3 days in the fridge.

Store in the freezer by placing each individual lemon bar on a baking sheet. Place the baking sheet in the freezer for 2-3 hours until they freeze all the way through. Once frozen, wrap each bar individually in plastic wrap and place them in a sealable bag or airtight container. They will keep in the freezer for up to 3 months!

Don’t forget to top them with powdered sugar when they come out of the oven! If you follow these steps you will end up with the best lemon bars recipe!

Can I Make Lemon Bars Ahead of Time?

A classic lemon bars recipe is a great option for a make ahead dessert. Just pop the lemon bars into the fridge to keep them until they’re ready for serving. Remember, this is a fresh tasting dessert unlike a baked cookie, so you should only make lemon bars about a day ahead of time.

  1. Nisheeta Curry says:

    Hey! I love this recipe, can I make this with store bought lemon curd? And should I add flour to the store bought lemon curd?

    1. Sweet Basil says:

      Hi Nisheeta! I have never tried it with store bought lemon curd, but it is worth a shot! I worry that it might be too loose to hold up on a bar, but I don’t think adding flour to it would be a good idea. I think it would just get lumpy. Sorry to not be much help!

  2. Renee says:

    Can you use salted butter instead of unsalted?

    1. Sweet Basil says:

      Yes, but I would omit the salt so it’s not too salty!

  3. Salli says:

    Will bottled lemon juice work just as well?

    1. Sweet Basil says:

      Bottled has a little more of a harsh taste so use a little less if you can, or half fresh half bottled

  4. Linda says:

    I love lemon bars! My frustration is with the powered sugar when it soaks in. I don’t know how to prevent that. I will be making these soon! 

    1. Sweet Basil says:

      You mean on the top? Letting the bars cool and kind of dry out their tops will help with that!
