Bite into these lemony bars and you'll get all the zingy sweetness you crave in a fudgy square with a punchy citrus glaze on top. That fresh lemon smell fills up your whole kitchen. Whenever I bring these along, folks always wish I'd made a couple pans instead of one.
The first time I tossed these lemon bars together on a lazy Saturday, the whole place smelled like pure sunshine and my crew couldn’t wait—they ate extra helpings straight outta the pan.
Zesty Ingredients
- Powdered sugar: makes the silky smooth glaze—sift it for no lumps
- Vanilla extract: gives it that bakery goodness Snoop out pure vanilla for the best smell
- Fresh lemon juice: keeps everything zippy and bright Look for lemons that are glossy and thin skinned—they’re juiciest
- Lemon zest: explodes with flavor and gives off those amazing lemony oils Always zest before juicing for max aroma
- Eggs: hold everything together and create that soft fudgy vibe Let 'em come to room temp to blend easy
- Unsalted butter: brings creamy richness Softened butter stirs in nice and even—no weird greasy bits
- Salt: kicks up all the lemon flavors Just use a pinch of fine sea salt for a pure taste
- Granulated sugar: keeps these chewy and sweet—balances out the tangy lemon If you can, grab superfine sugar
- All purpose flour: gives structure but doesn’t let the bars get dry Go for plain unbleached flour if you can
Easy Steps
- Make and Pour Glaze:
- Whisk powdered sugar with lemon juice plus a little zest in a bowl until it runs smooth Then pour all over the cooled bars and push it gently to the corners Let it sit for half an hour to firm up before slicing
- Wait for Them to Cool:
- Let your pan hang out on a wire rack until cold before adding glaze If you’re impatient, the frosting will melt right off and you’ll miss that sticky top
- Bake Time:
- Spoon your batter into the pan and spread it out Bake it at 350 for a solid 25 to 30 minutes You want just a light golden edge and a barely set, creamy middle Test with a toothpick—just a few moist crumbs sticking is perfect
- Mix Wet and Dry:
- Dump your flour and salt into the wet stuff and gently mix with a spatula until you can barely spot flour Don’t overdo it or your bars might turn out tough
- Combine Eggs and Lemon:
- Crack in the eggs one by one and mix well Add in the zest, lemon juice, and vanilla Give it all a final stir, making sure zest doesn’t clump
- Whip Butter and Sugar:
- Beat your soft butter with the sugar using a hand mixer for a few minutes—aim for pale, fluffy, and light so your bars bake up just right
- Do the Dry Mix:
- Stir up your flour and salt together so the flavor gets spread out even in every bite
- Prep Your Pan:
- Lay parchment in a 9x13 pan with the paper hanging over the sides for easy grabbing Grease the paper so nothing sticks

Zesting lemons is easily my favorite part The scent is unbeatable and you’ll never get it from a store bottle Every time I grab the zester, I remember my kid sneaking a still-warm bar from the rack with glaze barely holding on
How to Store
Keep leftover lemon bars in their pan with a tight wrap or shuffle slices into a sealed box They’re good at room temp for up to three days If you're storing longer, pop them in the fridge for freshness For the shiny top, let them breathe for a few hours, then loosely cover with wax or foil Put parchment between stacked bars so they don’t smush together
Swaps if Needed
Out of real lemons? Bottled juice will do, just toss in extra zest for kick For dairy free, grab a vegan butter that actually tastes good Want a nuttier vibe? Use almond extract instead of vanilla Gluten free folks, just swap in your favorite cup-for-cup GF flour blend
How to Serve
Chill them for a firmer snap or serve at room temp for that thick fudge feel For a party look, add a cloud of whipped cream and some zest Fresh berries make it festive or just dust a little extra powdered sugar for a pretty touch
