Sweet and tangy lemon bars with a creamy filling and a crisp and buttery shortbread crust, are the perfect dessert to make in spring.⁣ They are delicious and so easy to make and I just love that bright yellow color of them!

A few notes about this recipe:

– It’s best to use a glass or a ceramic pan. Because if you use a metal pan, the acid will react with the lemon juice and the bars will have a slight metallic taste.
– Also, make sure not to overcook the filling because it may get a rubbery texture instead of a smooth and creamy one.

Ingredients for a 8×8 inch pan:

Shortbread Crust:

  • 1/2 cup room temperature butter – 113 grams
  • 3 tablespoons powdered sugar – 20 grams
  • 1/2 tsp lemon zest
  • 1 teaspoon vanilla extract
  • 1 cup plus 3 tablespoons sifted flour – 145 grams
  • 1/8 tsp salt

Filling:

  • 3/4 cup + 1 tbsp granulated sugar – 162 grams
  • 3 tbsp all purpose flour – 22 grams
  • 1/8 tsp salt
  • 1 tablespoon lemon zest
  • 1/4 cup fresh lemon juice
  • 2 whole eggs and 1 egg yolk at room temperature
  • 1 tsp vanilla extract


Instructions:

Crust:

1. Firstly, preheat the oven to 350 F. Grease and line a 8×8 glass or ceramic pan with parchment paper and leave some overhang on the sides. I suggest that you don’t use a metal pan because it will give the bars a metallic taste.

2. Then, in a large bowl, add in the room temperature butter, powdered sugar, salt, lemon zest and vanilla extract. Then beat them all together for about 2 minutes until light and fluffy.

3. Lastly, add in the sifted flour and mix for a few seconds, just until the dough comes together. It’s important to not over beat the crust because it can get tough after baking.

4. Transfer the dough to your baking pan and press it with your hand to an even layer. If the dough sticks to your hand, flour your hand very slightly. You can bring the dough up to the edges just a bit to get some crispy yummy edges!

5. Bake in the oven for about 20 minutes or until the edges begin getting golden brown. While you are waiting you can measure your filling ingredients but don’t mix them together until ready to pour in the crust. Because if lemon juice and eggs sit together for a while they’ll react and it may become curdled and weird!

6. Take out the crust and let it sit while we make the filling. (You don’t want the crust to cool down completely, the filling should be added to a warm crust.)

Filling:

1. In a bowl add in sugar, lemon zest, salt and flour and whisk them together very well.

2. Next, juice some lemons (you probably need 1-2 lemons) to get 1/4 cup of juice and add it to the flour mixture.

3. Then, add in the eggs and vanilla extract and whisk all of them together really well. Don’t skip the vanilla extract because it gets rid of the egg smell.

4. Pour the filling over warm crust and bake for about 20 minutes or until the filling is just set. It means the top is white and when you gently shake the pan, you’ll see a very slight jiggle in the center. The center will continue cooking as the filling is cooling down.

5. Let the pan cool down on a wire rack completely, about an hour, and then refrigerate for 3 hours or overnight.

6. When you’re ready to serve, grab the overhang parchment paper and slowly lift the lemon bar out of the pan. Sometimes it gets a little sticky on the sides but don’t panic it will come out.

7. Use a large knife and cut it to squares, wiping off your knife after each cut.

8. Sprinkle with powdered sugar and more lemon zest if you like.

FAQs

Why won't my lemon bars set? ›

Ratio of Liquid to Thickener: If the recipe doesn't have the right balance of eggs (which act as a thickener) to liquid (lemon juice), the filling won't set properly. Solution: Ensure your recipe has enough eggs to set the lemon mixture. A good rule of thumb is about 2 large eggs per 1/2 cup of lemon juice.

Why can't I use a metal pan for lemon bars? ›

Metal can react with the acidity in the lemon juice, so to prevent a metallic taste in your lemon bars, ensure the cake tin is competely covered with parchment paper, or you can use a glass or ceramic dish too.

Why did my lemon bars get brown on top? ›

If your lemon bars are brown on top, you cooked them too long. To avoid burning and turning brown, remove the bars from the oven sooner, right when the filling is firm.

Do you put lemon bars in the fridge after baking? ›

Lemon bars should be stored in an airtight container and refrigerated in order to prevent bacterial growth or foodborne illness. The filling in lemon bars is made with eggs and can become a breeding ground for bacteria if it's kept in the danger zone (between 41 and 153 degrees F).

How to fix undercooked lemon bars? ›

If your baked goods are undercooked:
  1. If they are only slightly undercooked, you can try returning them to the oven and baking for a few more minutes.
  2. If they are significantly undercooked, you may need to extend the baking time significantly.

Why did my lemon bars fall apart? ›

There are a couple of things that can impact the integrity of your lemon bars. The first is if your crust has cracks in it and the lemon curd fills in the cracks. This can cause your lemon bar to break! It may also break if you don't bake the crust long enough or the lemon layer is underbaked.

Is it better to bake in foil or glass pans? ›

Aluminum is good for cakes, bars, and pies—but also for breads: focaccia, sandwich loaves, and rolls. Because metal heats up faster than glass, it contributes to a better rise and crisper, browner edges.

Why are my lemon bars foamy on top? ›

It is the air bubbles created from whisking the eggs rising to the surface during baking. Lemon bars taste the same with or without that layer and a dusting of icing sugar covers it right up!

Is it better to bake cake in glass or metal? ›

Most desserts like brownies, cookies, bars, and cakes bake best in a metal dish. The metal conducts heat evenly and efficiently, allowing the baked goods to heat and rise equally from edge to center, cooking at the same rate.

Why did my lemon bars flip upside down? ›

Set a timer for 5 minutes after pulling the crust from the oven to ensure it doesn't cool too much—if the shortbread is allowed to reach room temperature, the uncooked lemon curd will slip off the top and pool in the bottom of the dish, turning your lemon bars upside down (sounds bananas until it happens to you!).

Why did the top of my lemon bars crack? ›

Don't Over-Bake.

If you leave them in the oven too long, it can cause your bars to crack.

Why did the crust on my lemon bars rise to the top? ›

On very rare occasions, when making lemon bars, the shortbread may rise to the surface. (I've seen this happen once in 20+ years of making lemon bars.) This happens because the filling has found its way to the bottom of the pan, either through cracks in the crust or gaps at the edges of the pan.

How to cleanly cut lemon bars? ›

Dusting the knife with powdered sugar before cutting lemon bars can help to reduce sticking and create cleaner cuts. However, this is optional and depends on personal preference. If you prefer a more polished appearance on the bars, you can lightly dust the knife before each cut.

How many lemons make 1/3 cup juice? ›

A lemon produces between 1/4 and 1/3 cup fresh-squeezed juice. That equals about 4 to 5 tablespoons per lemon. To get the maximum amount of liquid from the fruit, microwave the lemon for 10 seconds before cutting and squeezing.

Do Krusteaz lemon bars need to be refrigerated? ›

Refrigerate and cut into squares. Best served chilled.

Why is my lemon filling not thickening? ›

If your lemon curd hasn't thickened, it may not have been heated enough. It can take up to 30 minutes of constant stirring to cook lemon curd, especially if it's a large batch. Remember that curd will thicken more once cooled.

Why did my lemon bars crack when cooling? ›

Don't Over-Bake.

If you leave them in the oven too long, it can cause your bars to crack.

Why is my lemon tree not doing well? ›

Besides diseases and pests, the leaves on your lemon tree may appear unhealthy or start dropping for other reasons. Nutrient deficiencies can cause discolored, yellow or curling leaves. If you don't see any signs of pests but your leaves don't look healthy, try a soil test to determine if there's a deficiency.

What is the trick to cutting lemon bars? ›

Dusting the knife with powdered sugar before cutting lemon bars can help to reduce sticking and create cleaner cuts. However, this is optional and depends on personal preference. If you prefer a more polished appearance on the bars, you can lightly dust the knife before each cut.
