What Ingredients You Will Need

This recipe uses simple, everyday ingredients to create a dessert that feels gourmet. Here’s what you’ll need:

• For the Shortbread Crust:
• 1 cup (226 grams) unsalted butter, softened
• 2 cups (250 grams) all-purpose flour
• 1/2 cup (100 grams) granulated sugar
• 1/4 teaspoon salt
• For the Lemon Filling:
• 1 1/2 cups (300 grams) granulated sugar
• 1/4 cup (32 grams) all-purpose flour
• 4 large eggs
• 2/3 cup (160 ml) freshly squeezed lemon juice (about 4-5 medium lemons)
• 1 tablespoon lemon zest
• For Garnish:
• Powdered sugar (optional, for dusting)

If you’re looking for substitutes, you can use gluten-free all-purpose flour for a gluten-free option. For dairy-free, swap the butter with a plant-based alternative. And if you want extra tang, add a teaspoon of lemon extract to the filling!

Equipment Needed

You don’t need a fancy kitchen to make these lemon bars, but here are some essentials:

• 9×13-inch baking pan: A glass or metal pan works well.
• Mixing bowls: You’ll need one for the crust and one for the filling.
• Whisk: For combining the filling ingredients smoothly.
• Electric mixer: Optional, but great for achieving a perfectly creamy crust.
• Parchment paper: Makes it easy to lift the bars out of the pan once baked.
• Microplane or zester: Essential for getting fine lemon zest.
• Spatula: For spreading the crust evenly in the pan.

If you don’t have a microplane, you can use the fine side of a box grater for zesting. And if you’re short on mixing bowls, repurpose a large measuring cup for the filling.

Preparation Method

1. Preheat your oven: Set your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal.
2. Make the shortbread crust: In a mixing bowl, beat together the softened butter, sugar, and salt until light and fluffy. Gradually add the flour and mix until a crumbly dough forms.
3. Press the crust into the pan: Transfer the dough to the prepared pan, pressing it evenly across the bottom to form a smooth layer. Use the back of a spoon or your fingers to flatten it out. Prick it lightly with a fork to prevent bubbles.
4. Bake the crust: Bake the crust in the preheated oven for 18-20 minutes, or until it’s lightly golden. Remove from the oven and let it cool slightly while you prepare the filling.
5. Prepare the lemon filling: In a separate bowl, whisk together the sugar and flour. Add the eggs, lemon juice, and lemon zest, and whisk until smooth and well combined.
6. Pour the filling over the crust: Once the crust has cooled a bit, pour the lemon mixture over the top, spreading it out evenly.
7. Bake the lemon bars: Return the pan to the oven and bake for 20-25 minutes, or until the filling is set and no longer jiggles in the center.
8. Cool completely: Remove the pan from the oven and let the lemon bars cool completely in the pan. Once cooled, use the parchment paper to lift them out.
9. Slice and serve: Dust the top with powdered sugar, then slice into squares or rectangles. Serve and enjoy!

Pro tip: Chill the lemon bars in the fridge before slicing for cleaner edges. If your filling cracks, don’t worry—dusting with powdered sugar will hide any imperfections beautifully!

Cooking Tips & Techniques

• Use fresh lemons: For the best flavor, always opt for fresh lemons rather than bottled lemon juice. The zest adds a vibrant citrus kick.
• Don’t overmix the crust: Overmixing can make the shortbread tough instead of tender. Stop mixing as soon as the dough comes together.
• Let the crust cool slightly: Pouring the filling onto a hot crust can cause it to cook unevenly. Allowing it to cool for a few minutes helps set the base.
• Watch the baking time: The filling should be just set—overbaking can lead to a rubbery texture. Check your bars around the 20-minute mark.
• Use parchment paper: This makes removing the bars so much easier. No sticking, no crumbling!

These tips have saved me from many kitchen disasters, especially when I was first learning how to make lemon bars. Trust me—it’s worth taking the extra steps for perfect results!

Variations & Adaptations

Here are a few fun twists you can try to customize your lemon bars:

• Berry Lemon Bars: Add a layer of raspberry or blueberry preserves between the crust and lemon filling for a fruity twist.
• Gluten-Free Lemon Bars: Swap the all-purpose flour for a gluten-free flour blend. Make sure your blend is suitable for baking for the best results.
• Extra Tangy Lemon Bars: Add an extra tablespoon of lemon zest or a splash of lemon extract for even more citrus punch.
• Coconut Lemon Bars: Sprinkle shredded coconut over the filling before baking for added texture and tropical flavor.

My personal favorite? Adding fresh raspberries on top before serving. The combination of tart lemon and sweet berries is a game-changer!

Serving & Storage Suggestions

Lemon bars are best served chilled or at room temperature, depending on your preference. Here are some tips to make them even better:

• Serving: Pair lemon bars with a cup of hot tea or coffee for a cozy treat, or serve them with whipped cream for extra decadence.
• Presentation: Dust the tops generously with powdered sugar for a pretty finish. You can also add a few lemon zest curls for a pop of color.
• Storage: Store leftover lemon bars in an airtight container in the refrigerator for up to 5 days.
• Freezing: To freeze, wrap individual bars tightly in plastic wrap and place them in a freezer-safe container. They’ll keep for up to 3 months. Thaw in the fridge before serving.
• Reheating: Lemon bars are best served cold, but if you prefer them warm, you can microwave them for a few seconds. Be careful not to overheat!

Fun fact: The flavors of lemon bars actually deepen after a day in the fridge, so they taste even better the next day!

FAQs

Can I use bottled lemon juice instead of fresh?

Fresh lemon juice is highly recommended for the best flavor. Bottled juice can taste artificial and won’t give you that same zingy freshness.

Can I make these lemon bars ahead of time?

Absolutely! Lemon bars can be stored in the fridge for up to 5 days or frozen for 3 months. They taste even better the next day as the flavors meld together.

How do I know when the filling is set?

Check the center of the lemon bars—it should no longer jiggle when you gently shake the pan. The edges will be slightly golden.

Can I use salted butter for the crust?

If you only have salted butter, reduce the amount of additional salt in the crust to avoid it being overly salty.

Why did my lemon filling crack?

Cracks can happen if the filling is overbaked or the oven temperature is too high. Make sure to check the bars early and remove them as soon as the filling is set.
