Zesty Lemon Brownies Citrus Bars

As seen in Sweet Treats to Satisfy Any Craving.

These lemon brownies are super bright and moist, with lots of citrus pop and a squishy, cake-like center. You just toss together fresh lemon juice and zest with a buttery mix, then pour over a quick, sugary citrus glaze for that sweet zing. They’re dense but not too heavy, and you’ll get a good mix of tart and sweet in every bite. Everything comes together in one mixing bowl, so cleanup’s a breeze. You’ll get neat slices if you chill first. Don’t use anything but real lemons for the loudest flavor. Be careful not to bake too long so they stay extra soft. They last a while and taste even punchier when cold.

If you’re after something other than chocolate, lemon brownies totally hit the spot. All that zesty lemon goodness shines through in every soft, moist bite, and there’s a punchy glaze on top that takes the tartness up a notch. Whip up a batch for a picnic or a speedy dessert after dinner—they’re basically sunshine you can eat.

Whenever my family sees this pan by the window, everyone gets excited. The whole place fills with that lemony smell and reminds us of summers making lemonade and just laughing together.

Yummy Ingredients

  • Lemon zest: tiny yellow flecks full of flavor—use fresh lemons and a fine grater for max citrus kick
  • Vanilla extract: smooths out all that tart and makes it smell amazing—stick with pure extract if you can
  • Powdered sugar: sift it first to keep your glaze lump-free and glossy
  • Granulated sugar: adds sweetness and balances the tang—use fine sugar so it blends fast
  • Extra lemon juice: thins out the glaze and amps up the lemon taste—fresh is always best
  • Salt: really makes the lemon pop—sea salt gives it a little extra oomph
  • Lemon juice: gives all the fresh tangy vibes—freshly squeezed is key
  • Large eggs: hold everything together and make it soft—use fresh ones for a nice rise
  • Unsalted butter: adds all the richness—grab the good stuff for the tastiest bars
  • All purpose flour: keeps things soft but structured—pick finely milled stuff for the best crumb
  • Lemon zest (in glaze): adds a pretty look and boosts the citrus—zest just right before mixing your glaze

Easy Step-by-Step

Slice and Enjoy:
Grab those parchment edges to lift everything out, then cut the cooled bars into little squares with a sharp knife for a hint of summer in each piece
Chill After Glazing:
Swipe the glaze all over the cooled squares then chill for about 15 minutes so the glaze firms up and you get tidy cuts
Whip Up the Glaze:
Mix together powdered sugar, lemon juice, and some fresh zest in a small bowl. You want it smooth and a little runny so it sits nicely on top
Cool it Down:
Let the bars cool completely before you try to add the glaze—makes slicing so much easier
Bake ‘Em:
Spoon the batter into your lined pan, smooth it out a bit, and bake for 22–25 minutes. Check with a toothpick—if it comes out with just a few crumbs, you’re good
Add Dry Stuff:
Gently fold the flour and salt into the mixture until you don’t see any dry bits. If you mix too much, the bars get tough, so take it easy
Mix in Eggs & Goodies:
Add each egg one at a time, mixing well. Toss in the zest, lemon juice, and vanilla, then stir it up until glossy and smelling like lemonade
Beat Butter and Sugar:
Use a sturdy whisk or hand mixer to beat soft butter and sugar together until it’s whipped up and pale
Get Your Pan Ready:
Line an 8x8 inch square pan with parchment, letting the edges hang over. This way, it’s super simple to lift the bars after baking and nothing sticks

Zesting the lemons is honestly the best part. The smell is unreal, and those tiny shreds make the bars look so pretty. My kid loves helping too, which means lots of giggles and sticky hands while we work.

Storage Magic

Just pop these lemon squares in a sealed container and they’ll be good on the counter for three days. Want them to last even longer? Stick them in the fridge—they’ll stay soft and tasty for a week. Drop parchment between layers to stop them from sticking together.

Swap Options

No unsalted butter? Go ahead and use salted, but cut the salt in half. Want to change things up? Try orange zest and juice—it’s super tasty. If you’re out of powdered sugar, blitz regular sugar in a spice grinder until fine for a glaze stand-in.

Tasty Ways to Serve

Honestly, these shine solo, but you can add a dollop of whipped cream or a big spoonful of berry compote if you’re feeling fancy. They’re great next to iced tea or mint lemonade at a summer party. For extra flair, toss fresh raspberries on top before serving.

Tradition and Lemon Bars

Sweet lemon treats are a big part of classic American baking. Turning lemon bars into soft, cakey squares makes them even more fun—think lemonade stands and backyard hangouts. That little twist turns something familiar into a tasty conversation starter.

Common Questions

→ What helps make the lemon brownies fluffy and moist inside?

Start by whipping up butter and sugar until it looks light and airy. After you stir in the flour, stop mixing as soon as things come together, and don’t leave them in the oven too long. That’s how you keep them tender.

→ Is it fine to swap in bottled lemon juice instead of fresh lemons?

You’ll get the strongest lemon punch if you use straight-from-the-fruit juice and zest, but if you’re out, bottled stuff works okay for flavor in a hurry.

→ Which pan size works best to bake these bars?

Use a square baking pan, eight inches per side, and line it with parchment paper. This way you can lift the bars out easily and they’ll bake nice and even.

→ When’s the best time to glaze the bars?

Don’t rush—wait for the bars to cool off totally. Then swap over the glaze on top. Pop them in the fridge first if you want nice clean cuts.

→ How do you keep lemon brownies tasting fresh?

Seal them in an airtight box and keep at room temp for a couple days, or stash them in the fridge if you want them to last longer.

What You'll Need

→ Brownie Base

01 1/2 teaspoon vanilla extract
02 2 tablespoons lemon juice
03 2 tablespoons lemon zest
04 2 large eggs
05 1/2 cup unsalted butter, let it soften
06 1/4 teaspoon salt
07 3/4 cup sugar (the regular kind)
08 1 cup regular flour

→ Glaze

09 1 teaspoon grated lemon peel
10 1 tablespoon lemon juice
11 1/2 cup powdered sugar

Step-by-Step Directions

Step 01

Cut these into 9 even pieces, then dig in.

Step 02

Once the glaze is on, stick the brownies in the fridge for about 15 minutes till the topping firms up.

Step 03

Mix together the powdered sugar, lemon juice, and some zest till you don't see any lumps.

Step 04

Let everything chill in the pan until it's not warm at all before adding any topping.

Step 05

Pour your batter in the lined pan and level it out. Pop it in the oven for 22 to 25 minutes. You want a toothpick to come out clean from the middle.

Step 06

Dump the flour and salt in and mix just until you can't see dry spots anymore. You don't want to stir much.

Step 07

Drop in the eggs, one after another. Mix it up after each. Now toss in the lemon juice, all the zest, and the splash of vanilla.

Step 08

With a mixer in a big bowl, whip up the softened butter and sugar till they're really fluffy and combined well.

Step 09

Heat the oven to 350°F (175°C). Put down parchment paper inside an 8x8 pan so nothing sticks.

Helpful Notes

  1. Freshly squeezed lemon juice and zest really brighten up the taste.
  2. Just bake until the middle isn't gooey. Overbaking dries them out.
  3. Keep bars in a sealed container at room temp for up to 3 days, or in the fridge if you want them to last longer.
  4. For extra citrus flavor, you can splash in a little lemon extract if you want things tangier.
