Air Fryer Lemon Bars

by

There’s something magical about lemon desserts. They’re light but indulgent. Sweet but sharp. Comforting yet refreshing.

And when you make them in the air fryer?
Game changer.

These lemon bars have:

✔ A tender, buttery shortbread crust
✔ A silky smooth lemon filling
✔ The perfect balance of sweet and tart
✔ A soft custard-like center that melts in your mouth

And the best part? No need to turn on the big oven.

🧈 Ingredients

For the Shortbread Crust:

  • 1 cup (125g) all-purpose flour

  • ½ cup (113g) unsalted butter, softened

  • ¼ cup (50g) granulated sugar

  • Pinch of salt

For the Lemon Filling:

  • 2 large eggs (room temperature)

  • ¾ cup (150g) granulated sugar

  • 2 tablespoons all-purpose flour

  • ¼ cup (60ml) fresh lemon juice (about 2 lemons)

  • 1 tablespoon lemon zest

  • ½ teaspoon vanilla extract

  • Pinch of salt

For Topping:

  • Powdered sugar for dusting

🍋 Why Fresh Lemon Juice Matters

Always use freshly squeezed lemon juice.

Bottled juice:

  • Tastes flat

  • Lacks brightness

  • Can be bitter

Fresh juice gives:

  • Natural citrus aroma

  • Balanced tartness

  • Vibrant flavor

🥣 Step 1: Make the Shortbread Crust

In a mixing bowl:

Add:

  • Softened butter

  • Sugar

Cream together until smooth and slightly fluffy.

Add:

  • Flour

  • Salt

Mix until crumbly dough forms.

The dough should feel:

  • Soft

  • Slightly crumbly

  • Not sticky

🧁 Step 2: Prepare the Pan

Use a small baking pan that fits inside your air fryer basket (about 6–7 inches).

Line it with parchment paper. Leave extra paper hanging over the sides so you can lift the bars out later.

Press the dough evenly into the bottom of the pan.

Use your fingers or the back of a spoon to flatten.

Make sure it’s:

  • Even thickness

  • Pressed firmly

  • No cracks

🔥 Step 3: Air Fry the Crust

Preheat air fryer to 320°F (160°C) for 3 minutes.

Place the crust inside and cook for:
10–12 minutes

You want:

  • Light golden edges

  • Slight firmness in center

Do not overbake.

Remove and let cool slightly while preparing filling.

🍯 Step 4: Make the Lemon Filling

In a bowl, whisk together:

  • Eggs

  • Sugar

Whisk until slightly pale.

Add:

  • Lemon juice

  • Lemon zest

  • Flour

  • Vanilla

  • Salt

Whisk gently until smooth.

Do not overwhisk — too much air creates bubbles.

Strain mixture if needed for extra smooth texture.

🍋 Step 5: Pour & Air Fry Again

Pour lemon filling over warm crust.

Tap the pan gently to remove air bubbles.

Return to air fryer at 300°F (150°C).

Cook for:
12–15 minutes

The center should:

  • Jiggle slightly

  • Not look liquid

  • Set around edges

It will firm up as it cools.

❄ Step 6: Cooling Is Critical

Let bars cool completely at room temperature.

Then refrigerate at least:
2–3 hours

This step ensures:

  • Clean cuts

  • Proper set texture

  • Deep flavor development

✂ Step 7: Slice & Dust

Lift bars using parchment paper.

Cut into squares using a sharp knife.

Wipe knife clean between cuts for neat edges.

Dust generously with powdered sugar.

🌟 Texture Breakdown

When done right, your bars will have:

Top: Soft, smooth, lightly glossy
Middle: Creamy lemon custard
Bottom: Buttery, slightly crumbly crust

Every bite:
Sweet → Tangy → Buttery → Melt-in-your-mouth finish

🍋 Flavor Secrets

1️⃣ Add Extra Zest for Bold Flavor

More zest = stronger lemon aroma.

2️⃣ Add 1 Tablespoon Heavy Cream

For silkier filling.

3️⃣ Use Room Temperature Eggs

Ensures smooth custard.

🧊 Storage Guide
