Classic lemon bars start with a buttery shortbread crust and a sweet and tangy lemon curd filling. As a lemon lover, these are not only the best lemon bars, but also the best lemon desserts for the spring and summer months.

The best lemon bar
Those were the days when strawberries ruled all and were the only dessert Strawberry ice cream And Strawberry Birthday CakeI was introduced to a lemon dessert bar that ultimately changed the course of my dessert life for several years.
A little dramatic? Perhaps, but the fact is that the tangy lemon bar’s first introduction left an indelible impression. I was 8 or 9 years old, and I went to a tea house with my mother and some of our friends. I enjoyed the tea sandwiches, mostly put off my tea, and looked forward to the dessert tray that I knew was coming.
It was full of small desserts, including bite-sized squares of mini tarts, mini muffins, shortbread cookies, and lemon bars. The first bite of the tangy lemon with the buttery shortbread crust was incredible. At that point, it blew all other sweets out of the water.
By far, a classic lemon bar with silky smooth lemon curd and a sandy shortbread cookie crust is, in my opinion, one of the best lemon desserts in existence. There’s nothing quite like the lip-puckering tangy lemon flavor paired with a sweet crust and powdered sugar topping.

What makes this easy lemon bar a fan favorite?
1. Simple ingredients: Homemade lemon bars require very few ingredients and most of them are repeat ingredients of shortbread crust and lemon filling.
2. Simple recipe: With the same ingredients, this is a very easy lemon bar recipe with a shortbread crust (a very buttery, melt-in-your-mouth shortbread crust). The hardest part is waiting for the bars to cool.
3. Perfect texture and flavor: Lemon squares can be very, very sweet, and they can also be very, very tangy. This lemon bar recipe has the perfect flavor and texture. My secret ingredient? Lemon juice! Many homemade lemon square recipes call for lemon juice only. The zest adds so much flavor without adding too much liquid or tang!

Let’s talk about the ingredients:
- Melted unsalted butter: Unsalted butter is important in this recipe because the recipe already contains salt. If you use salted butter, the recipe will be too salty.
- All purpose flour
- Powdered Sugar: The granulated sugar will make the crust a bit grainy. Powdered sugar is finer so it makes the perfect buttery, sandy shortbread crust.
- salt
- Lemon Zest: It’s a subtle hint of lemon, but adding lemon to a shortbread crust enhances the flavor of both the crust and the filling.
- the egg
- granulated sugar
- Lemon juice: Make sure you use fresh lemon juice, as it has the best flavor. Bottled lemon juice tastes slightly different than fresh lemon juice.
How to make lemon bars from scratch:
- Shortbread Crust: Mix together the flour, powdered sugar, salt and lemon zest. Drizzle in melted butter. Mix until all ingredients are combined.
- Bake: Line a 9×9 baking pan with non-stick foil or parchment paper (or grease with baking spray). Press the crust into the bottom of the pan. Bake. cool
- Lemon Filling: Whisk together the eggs, lemon zest and juice. Add the granulated sugar and flour and stir until smooth (there are small lumps here and there).
- Bake: Pour filling over par-baked shortbread crust. Bake.
- cooling: Allow the lemon bars to cool before adding the powdered sugar. You can serve them chilled at room temperature or refrigerate.

Storage Tips:
Refrigerate your lemon bars. Because of the custard/yogurt fillings (made with eggs) that not only taste nice and cold, they also need to be refrigerated until you’re ready to serve.
Freezer Tips:
- Can you freeze lemon bars? yes Freeze them before adding the powdered sugar (add each time you serve the bars).
- Pro Tips:
- Allow bars to cool to room temperature before cutting into squares. Then, flash freeze them evenly spaced on a baking tray. Freeze for 1-2 hours.
- After flash freezing, wrap each bar individually in plastic wrap and store in a freezer safe container. (Flash freezing keeps them from getting too messy when wrapped in plastic wrap, and it prevents the bars from sticking too much to the plastic wrap.)
- When you’re ready to serve, you can unwrap them and place them on a serving tray. It takes about 30-45 minutes to thaw at room temperature. Or, you can thaw them overnight.
- Top with powdered sugar before serving.

Ultimate Classic Lemon Bar Tips and Tricks:
- Powdered sugar and granulated sugar: We make this shortbread crust with powdered sugar and lemon curd granulated sugar filling. It’s really, really important that you don’t make your shortbread with granulated sugar, otherwise it will be too grainy.
- Par Bake Shortbread Crust: The crust needs to be baked a little first. The crust is done as soon as it starts to turn light golden brown. If it’s too long, the crust may be overdone when you bake the lemon bars later.
- Fresh lemon juice and zest: This recipe calls for both lemon juice and lemon zest. Be sure to use fresh lemon juice in this recipe and make sure you don’t use too much overripe Lemons (the ones that are squishy and turning brown/yellow). Overripe lemons are hard to shake, and they often taste like very bitter lemon juice rather than fresh lemon flavor.
