Ingredients
Servings
8
- 1 1/2 cups gluten-free rolled oats
- 1/2 cup almond flour
- 1/4 cup ground flaxseed
- 2 tablespoons coconut sugar
- 1 teaspoon gluten-free baking powder
- 1/4 teaspoon fine sea salt
- 1/2 teaspoon ground cinnamon
- 1/4 cup unsweetened applesauce
- 1/3 cup unsweetened almond milk
- 2 tablespoons fresh lemon juice
- 1 tablespoon lemon zest (about 1 lemon)
- 1/4 cup maple syrup
- 1 teaspoon pure vanilla extract
- 1 cup fresh or frozen blueberries (if frozen, thaw and drain excess moisture)
- Optional toppings
- extra lemon zest or a light dusting of vegan powdered sugar
Instructions
-
In a large bowl, combine gluten-free rolled oats, almond flour, ground flaxseed, coconut sugar, gluten-free baking powder, salt, and ground cinnamon. Stir well to evenly mix all dry ingredients.
-
In a separate smaller bowl, whisk together unsweetened applesauce, almond milk, fresh lemon juice, lemon zest, maple syrup, and vanilla extract until smooth and fully combined.
-
Pour the wet ingredients into the dry mixture and gently stir until fully combined into a thick batter. Carefully fold in the blueberries to avoid crushing them.
-
Prepare a small square baking pan or heatproof dish (about 7x7 inches) that fits your air fryer basket. Lightly grease with coconut oil or line with parchment paper for easy removal.
-
Transfer the batter into the prepared pan, spreading evenly and smoothing the top with the back of a spoon or spatula.
-
Preheat your air fryer to 340°F (170°C). Place the pan inside the air fryer basket and cook for 15-18 minutes, or until edges are golden and a toothpick inserted in the center comes out clean or with moist crumbs.
-
Carefully remove the pan from the air fryer. Let the bars cool in the pan for 10 minutes, then lift them out using the parchment paper (if used) and cool completely on a wire rack before slicing into bars.
-
Serve immediately or store in an airtight container at room temperature for up to 3 days, refrigerate up to a week, or freeze for longer storage.
-
Optional: Sprinkle extra lemon zest or a light dusting of vegan powdered sugar on top before serving for a fresh, bright finish.
Tips
Air Fryer Model Notes
Cook Air Fryer Vegan Blueberry Lemon Breakfast Bars in a single layer when possible. Basket models may need batches; oven-style models may need a tray rotation halfway through for even browning.
Crispiness Control
Pat the s gluten-free rolled oats dry, avoid crowding, and use only a light coat of oil or sauce before cooking. Add wet sauces near the end when you want the outside to stay crisp.
Doneness Cues
Look for browned edges, a hot center, and the texture described in the instructions.
Reheat In The Air Fryer
Reheat leftovers at 325 F to 350 F in a single layer until hot and crisp again. Add fresh herbs, citrus, or sauce after reheating.

Ingredient Replacements
If substitutions are needed, these swaps maintain the blueberry lemon bars’ flavor, texture, and wholesome profile:
- Rolled Oats: Certified gluten-free oats or quinoa flakes provide a slightly different texture and extra protein.
- Almond Flour: Oat or sunflower seed flour works as nut-free alternatives while preserving tenderness.
- Ground Flaxseed: Finely ground chia seeds offer a vegan binder replacement.
- Coconut Sugar: Maple sugar, brown sugar, or coconut nectar provide sweetening with different glycemic effects.
- Gluten-Free Baking Powder: Use commercially gluten-free baking powder or combine baking soda with cream of tartar as a substitute.
- Unsweetened Applesauce: Mashed banana or pumpkin puree can replace applesauce for flavor and moisture variations.
- Almond Milk: Any plant-based milk (oat, soy, cashew) suits different preferences or allergies.
- Fresh Lemon Juice and Zest: Lime juice/zest adds zestiness while orange zest delivers a sweeter citrus twist.
- Maple Syrup: Non-vegan honey, agave nectar, or date syrup keep sweetness and moisture intact.
- Blueberries: Use raspberries, blackberries, or chopped strawberries for flavor and texture alternatives.
These substitutions keep the recipe air-fryer-friendly, vegan, gluten-free, and healthy, offering flexibility for your ingredient availability or dietary needs.
Storage
Store leftover Air Fryer Vegan Blueberry Lemon Breakfast Bars in an airtight container in the refrigerator for up to 3 days. Cool the food before sealing so excess steam does not soften the texture.
Freeze only if the main ingredient and coating are freezer-friendly. Wrap tightly and freeze for up to 1 month, then thaw overnight in the refrigerator before reheating.
Reheat in the air fryer at 325 F to 350 F in a single layer until hot and crisp again. Add fresh herbs, citrus, or sauce after reheating for the best flavor.
