These Air Fryer Lemon Bars bring together a buttery shortcrust and a zesty lemon filling for a tangy dessert that’s ready in just 20 minutes of cook time. After testing methods from top air fryer dessert recipes, this version consistently produces bars that are perfectly balanced—crispy edges, gooey lemon center, and a dusting of powdered sugar for a bakery-style finish.
Perfect Air Fryer Lemon Bars Recipe
This recipe works beautifully in the air fryer because it uses a thin baking pan, allowing hot air to circulate evenly. The crust bakes until golden, then the lemon filling sets to a luscious texture without the need for an oven. Fresh lemon zest is the secret to the bright flavor, and cooling the bars before slicing ensures perfect squares every time.
Ingredients
- For the Crust
- 1 cup unsalted butter (room temperature)
- ½ cup granulated sugar
- 2 cups all-purpose flour
- For the Filling
- 4 large eggs (room temperature)
- 1½ cups granulated sugar
- ¼ cup all-purpose flour
- ½ cup fresh lemon juice (about 2–3 medium lemons)
- 1 tablespoon lemon zest
- For Serving

Ingredient Tips:
- Substitute gluten-free flour for the crust and filling if needed.

- Always zest lemons before juicing for maximum flavor.
Instructions
- Preheat your air fryer to 320°F (160°C) for 3 minutes if required.
- In a bowl, mix butter, sugar, and flour until crumbly. Press firmly into a thin baking pan.
