What Are Lemon Bars?
Lemon bars are a classic dessert made with two delicious layers. The bottom layer is a rich, buttery shortbread crust, while the top is a creamy lemon custard made with eggs, sugar, and fresh lemon juice. Once baked and chilled, they’re dusted generously with powdered sugar before serving.
Air frying creates a tender crust and perfectly set filling while reducing overall cooking time.

How to Make Air Fryer Lemon Bars
Step 1: Make the Crust
In a mixing bowl, combine the flour, sugar, and salt.
Add the softened butter and mix until a soft dough forms.
Press the dough evenly into a parchment-lined 7-inch baking pan.
Step 2: Bake the Crust
Preheat the air fryer to 320°F (160°C).
Bake the crust for 10–12 minutes until lightly golden.
Remove and allow it to cool slightly.
Step 3: Prepare the Filling
In another bowl, whisk together the eggs and sugar until smooth.
Add the flour and whisk until no lumps remain.
Stir in the fresh lemon juice and lemon zest.
Mix until fully combined.
Step 4: Fill the Pan
Carefully pour the lemon mixture over the warm crust.
Smooth the surface gently.
Step 5: Air Fry
Return the pan to the air fryer.
Bake at 300°F (150°C) for 12–15 minutes, or until the center is just set with a slight wobble.
Avoid overbaking.
Step 6: Cool Completely
Allow the lemon bars to cool at room temperature.
Transfer to the refrigerator for at least 2 hours.
Chilling helps the filling firm up for clean slices.
Step 7: Slice and Serve
Dust generously with powdered sugar.
Slice into squares using a sharp knife.
Serve chilled or at room temperature.
