What Is Lemon Bars with Powdered Sugar?
Lemon bars with powdered sugar are that sweet spot between bright and cozy: a buttery shortbread base, topped with a smooth lemon custard that bakes into a sliceable, sunshiney layer. The powdered sugar isn’t just for looks—it softens the tart edge and gives every bite a little “bakery finish” without needing frosting.
What makes them different from lemon cake or lemon curd tart?
- Texture: shortbread stays crisp-tender, not fluffy like cake
- Filling: a baked custard (eggs + lemon + sugar) that sets cleanly
- Finish: powdered sugar adds sweetness + that classic lemon-bar contrast
Two-layer anatomy (quick guide):
| Layer | What it does | What to look for |
|---|---|---|
| Shortbread crust | buttery structure | pale-golden edges, firm center |
| Lemon filling | tangy “custard bar” | set with a gentle jiggle |

Description
These Lemon Bars with Powdered Sugar are bright, sweet-tart, and beautifully sliceable. A buttery shortbread crust supports a smooth lemon custard filling, finished with a generous snowy dusting of powdered sugar—an easy dessert that always feels special.
Ingredients
SHORTBREAD CRUST:
1 cup all-purpose flour
1/4 cup granulated sugar
1/2 cup unsalted butter, cold and cubed (1 stick)
1/4 teaspoon fine salt
LEMON FILLING:
2 large eggs, room temperature
1 cup granulated sugar
1/2 cup freshly squeezed lemon juice
2 tablespoons all-purpose flour
1/4 teaspoon fine salt
1 teaspoon lemon zest (optional, for extra brightness)
TOPPING:
powdered sugar, for dusting
Instructions
1. Preheat the oven to 350°F (175°C). Line an 8×8-inch pan with parchment (optional) or grease well.
2. Make the crust: In a bowl, mix flour, granulated sugar, and salt. Cut in the cold butter until the mixture looks like coarse crumbs.
3. Press the crust firmly into an even layer in the pan. Bake 18–20 minutes, until lightly golden at the edges.
4. Let the crust cool completely (this helps prevent a soggy bottom).
5. Make the filling: Whisk eggs, sugar, lemon juice, flour, salt, and zest (if using) until smooth.
6. Pour the filling over the cooled crust.
7. Bake 15–20 minutes, until the edges are set and the center has a slight jiggle.
8. Cool completely at room temperature, then refrigerate at least 2 hours before slicing.
9. Dust with powdered sugar right before serving for the prettiest finish.
Notes
For clean slices, chill fully and wipe your knife between cuts.
Dust powdered sugar just before serving—if it sits too long, it can melt into the top.
Storage: Refrigerate in an airtight container up to 5 days.
Freezing: Freeze bars (without powdered sugar) up to 3 months; thaw overnight in the fridge and dust before serving.
Reheating is optional—lemon bars are best chilled. If you prefer slightly warm, heat at 300°F (150°C) for 5–8 minutes.

Ingredients Lemon Bars with Powdered Sugar (And Why They Matter)
Great lemon bars rely on a careful balance of richness, acidity, sweetness, and structure. Each ingredient plays a specific role in creating the perfect contrast between the buttery crust and the tangy lemon filling.
Shortbread Crust Ingredients & Purpose
- All-purpose flour — Forms the structure of the crust and keeps it tender rather than bready
- Granulated sugar — Adds sweetness and helps the crust brown lightly
- Unsalted butter — Creates that signature crumbly, melt-in-your-mouth texture
- Salt — Sharpens the sweetness and enhances the buttery flavor
A high butter ratio is essential here — it gives the crust its classic rich, delicate bite.
Lemon Filling Ingredients & Purpose
- Eggs — Provide structure and a silky custard-like texture
- Granulated sugar — Balances the sharpness of the lemon
- Fresh lemon juice — Delivers brightness, acidity, and true citrus flavor
- All-purpose flour — Thickens the filling so it sets cleanly when sliced
- Salt — Prevents the filling from tasting flat or overly sweet
Fresh lemon juice makes a noticeable difference — it creates a brighter, fresher flavor than bottled juice.
Topping
- Powdered sugar — Adds visual elegance and a soft sweetness that complements the tart filling
Tip: Using room-temperature eggs helps the filling bake more evenly and prevents curdling.
Lemon Bars with Powdered Sugar — Ingredient Swaps
Need to make a substitution? Here are a few ideas:
| Needs | Swap | Why |
|---|---|---|
| Unsalted butter | Salted butter | Reduces need for added salt |
| Freshly squeezed lemon juice | Bottled lemon juice | Provides the same bright, tart flavor |
| All-purpose flour | Gluten-free flour blend | For a gluten-free version |
| Granulated sugar | Coconut sugar | Provides a deeper caramel note |
Lemon Bars with Powdered Sugar — Tools You’ll Need
To make these lemon bars, you’ll need a few basic baking tools:
- 8×8-inch baking pan
- Parchment paper (optional, for easy removal)
- Mixing bowls
- Whisk
- Electric hand mixer or stand mixer
- Measuring cups and spoons
- Zester or grater (optional, for extra lemon zest)
How to Make Lemon Bars with Powdered Sugar (Step-by-Step)
Lemon bars come together in two simple layers — a buttery shortbread base and a smooth lemon custard topping. The key to success is building structure in the crust before adding the filling.
Step 1: Prepare the Shortbread Crust
- Preheat your oven to 350°F (175°C)
- Line or grease an 8×8-inch baking pan
- Combine flour, sugar, and salt in a bowl
- Cut in the butter until the mixture looks like soft, sandy crumbs
- Press the mixture firmly into the pan so the crust forms a smooth, even layer.
- Bake for 18–20 minutes, until lightly golden
Why it matters: Baking the crust first prevents it from becoming soggy once the lemon filling is added.
Step 2: Make the Lemon Filling
- Whisk eggs, sugar, lemon juice, flour, and salt until smooth
- Pour the filling over the cooled crust
- Bake for 15–20 minutes, until the center is set but slightly jiggly
Step 3: Cool & Finish
- Cool completely at room temperature
- Place in the refrigerator for a minimum of 2 hours to ensure the filling fully sets before cutting.
- Dust generously with powdered sugar before slicing
Pro Tip: Clean slices come from fully chilled bars — patience makes a difference.
The Secret to Bakery-Style Lemon Bars (Elodie’s Kitchen Notes)
What separates good lemon bars from the kind you daydream about is balance — not just in flavor, but in texture, structure, and aroma. The best lemon bars feel bright without being sharp, rich without being heavy, and tender without falling apart.
Sometimes, it’s the quiet, subtle touches that make all the difference:
What elevates lemon bars from homemade to bakery-level
- Rubbing lemon zest into sugar before mixing (it releases fragrant citrus oils)
- Fully baking the crust so it stays crisp beneath the custard
- Using room-temperature eggs for a smoother, silkier filling
- Letting the bars chill long enough to slice cleanly and neatly
Texture goals to look for
- A crust that’s crumbly yet sturdy
- A filling that’s set but still soft and creamy
- A finish that feels light, bright, and not overly sweet
If you ever feel like lemon desserts can be too tart or too sugary, this recipe strikes that “just right” middle ground — lively, sunny, and indulgent in a gentle, elegant way.
It’s the kind of dessert that feels nostalgic, polished, and quietly impressive — the kind you serve when you want something simple, beautiful, and guaranteed to make people smile.
Lemon Bars with Powdered Sugar Nutrition Notes
Lemon bars are a butter-and-egg dessert, so they naturally land in the “treat” category: rich shortbread on the bottom, custardy citrus on top. The good news is that the lemon juice brings brightness, so they taste lively and satisfying even in a small square.
What affects the numbers most
- Butter amount (crust): biggest driver of calories + saturated fat
- Sugar level (filling + dusting): biggest driver of total carbs/sugars
- Egg count: adds protein and helps the filling set, but also adds cholesterol
- Bar size: the easiest “control knob” for nutrition—smaller squares still feel special
Quick nutrition snapshot (typical range)

| Calories | ~150–200 |
| Carbs | ~18–25g |
| Fat | ~8–12g |
| Protein | ~2–4g |
Helpful note for readers: nutrition labels are always estimates because butter brands, egg sizes, and lemon juice yield vary.
Lemon Bars with Powdered Sugar Variations
Once you’ve nailed the classic, lemon bars become a little playground—tiny changes can shift the flavor without breaking the recipe. My “Elodie rule” is simple: change one element at a time so your bars still slice neatly and taste balanced.
Easy variation ideas (pick one):
- Lemon-Blueberry: fold in a small handful of blueberries for juicy pops (pair with Lemon Blueberry Pancakes energy)
- Citrus Twist: swap part of the lemon juice for orange (inspired by Clementine Curd)
- Berry-Curd Swirl: spoon a little Blackberry Curd on top and gently swirl before baking
- Extra-Zesty: add lemon zest to the sugar and rub together for 30 seconds (huge aroma boost)
- Coconut Finish: sprinkle toasted coconut after dusting sugar (for a sunny, tropical note)
Variation cheat table:
| Variation | Change | Result |
|---|---|---|
| Blueberry | add berries | fruity bursts |
| Orange-lemon | swap some juice | softer citrus |
| Curd swirl | swirl curd | dramatic look |

Lemon Bars with Powdered Sugar Serving Ideas
Lemon bars shine when you serve them cold and cleanly sliced—that’s when the filling feels smooth, the crust stays crisp, and the powdered sugar looks like a little snowfall. They’re perfect for brunch tables, bake sales, lunchboxes, or an afternoon treat that feels fancy with almost zero effort.
My favorite ways to serve them (choose your vibe):
- Brunch plate: lemon bars + fresh berries + coffee
- Dessert board: lemon bars + chocolate + fruit + something creamy
- Party squares: cut small, dust right before serving, and watch them vanish
Pairing ideas (simple + pretty):
- With something cool and creamy: Strawberry Yogurt Pops with Granola
- With a citrus-friendly cookie: Blueberry Lemon Heaven Cookies
- With a “treat-yourself” moment: Tiramisu Chia Pudding
Serving tips that actually help:
- For gifting: place bars in parchment layers so the tops stay tidy.
- Dust powdered sugar right before serving (it melts if it sits too long).
- Use a hot, dry knife for clean slices.
How to Store and Reheat Lemon Bars with Powdered Sugar
Because lemon bars have an egg-based filling, they should be treated like a chilled dessert: store cold, cover well, and don’t leave them sitting out too long.
Refrigerator storage (best texture + freshness)
- Cool completely, then cover tightly
- Store in an airtight container in the fridge
- Best quality: about 3–4 days (still lovely and bright)
- If you’re serving stacked layers, place parchment between slices to prevent sticking
Food-safety basics: keep your fridge at 40°F / 4°C or below and don’t leave perishable desserts out more than 2 hours.
Freezing (make-ahead friendly)
- Freeze bars without powdered sugar (it can melt/gum up)
- Wrap well + store airtight
- Best quality: about 3–4 months
- Thaw overnight in the fridge, then dust with sugar right before serving
Reheating (optional)
Lemon bars are best chilled, but if you want them slightly warm: 5 minutes at 300°F on a tray—just until the chill lifts (don’t overheat or the filling can weep).
Lemon Bars with Powdered Sugar — FAQ’s
Can I substitute bottled lemon juice for fresh lemon juice in lemon bars?
Yes, bottled lemon juice works in a pinch, but freshly squeezed lemon juice delivers a brighter, more vibrant flavor. Fresh juice also has natural citrus oils that give lemon bars a fresher, more aromatic finish. If flavor is your priority, fresh lemons are worth it.
How do you know when lemon bars are fully baked and set?
Lemon bars are done when the edges are set and the center has only a slight jiggle. The filling should look firm but not dry or cracked. Overbaking can cause the custard to become rubbery or split, so it’s best to pull them while the center is just set.
Do lemon bars need to be refrigerated?
Yes. Because lemon bars contain an egg-based custard filling, they should be stored in the refrigerator. Keeping them chilled preserves both food safety and texture, and they actually taste better once fully cooled and set.
Why did my lemon bars turn out runny?
Runny lemon bars usually happen due to:
– Underbaking
– Too much lemon juice
– Not enough flour in the filling
– Cutting before they fully cooled
For best results, let bars cool completely and chill for at least 2 hours before slicing.
Can I make lemon bars ahead of time?
Absolutely — lemon bars are an excellent make-ahead dessert. In fact, their flavor often improves after a day in the fridge. You can bake them 1–3 days in advance and dust with powdered sugar just before serving.
Lemon Bars with Powdered Sugar — Final Thoughts
There’s a reason lemon bars remain a beloved classic — they’re bright, comforting, and endlessly satisfying. This recipe delivers a smooth, tangy filling balanced by a rich, buttery crust, all finished with a delicate dusting of powdered sugar.
