Ingredients explained

🥣 100 g oat flakes — energetic base and rich in fiber.
🥜 50–80 g chopped nuts (almonds, walnuts, hazelnuts) — provides crunch and healthy fats.
🌻 50 g mixed seeds (sesame, chia, flaxseed, sunflower) — vegetable protein and texture.
🍇 50–80 g dried fruits (raisins, blueberries, apricots) — natural sweetness and antioxidants.

🍎 1 grated apple — juiciness and fruity flavor.
🥥 3–4 tablespoons coconut oil — helps unite and provides softness.
🥄 2–3 tablespoons sesame paste or peanut butter — binds ingredients and adds protein.
🍯 2–3 tablespoons of sugar (adjustable according to banana ripeness) — balanced sweet flavor.
🍯 2–3 tablespoons agave syrup or honey — moist texture and natural sweet flavor.

💧 2–3 tablespoons hot water — helps integrate all the ingredients.
Optional: a pinch of cinnamon or vanilla for an aromatic touch.

Equipment and preparation

What you need: A medium air fryer (3-5 L) works perfect for this rectangular pan. Utensils: a large bowl, a small saucepan, a wooden spoon or spatula, and an air fryer-safe mold. Baking paper is useful for unmolding.

Previous preparation (mise en place): Grate the apple, mash the banana, measure oats, seeds, nuts and dried fruit. Heat the oil and mix with sesame paste, sugar and lemon juice so that everything is ready before combining with the dry ingredients. This makes the process smoother and prevents the mixture from cooling or hardening prematurely.

Step by step instructions

① Prepare the mold

Line a small rectangular air fryer-safe mold with baking paper to make it easier to remove from the mold. This ensures that your bars come out intact and prevents them from sticking.

② Wet mix

Heat coconut oil with sesame paste, sugar and lemon juice until well combined. Don’t let it boil. This will help the mixture distribute evenly over the dry ingredients.

③ Add fruits and banana

Add the grated apple, mashed banana, agave syrup and hot water. Mix until you achieve a uniform, sticky paste ready to combine with the dry ingredients.

④ Mix with the dry ingredients

In a large bowl, combine rolled oats, nuts, seeds and dried fruit. Pour in the wet mixture and stir until everything is well coated.

⑤ Compact the mixture

Pour the dough into the mold and press with a spoon or slightly damp hands to form an even layer of 1–1.5 cm. Let rest 5–10 min.

⑥ Cooking in an air fryer

Preheat the fryer to 140°C and cook for 40 min. Check halfway through: if the surface browns too much, cover loosely with aluminum foil.

⑦ Cool and cut

Let cool completely in the mold (1 hour minimum) and then cut into bars with a sharp knife. This way they stay firm and don’t fall apart.

Pro tips and troubleshooting

🌟 Secrets to success:

Use very ripe bananas for less sugar.
Press the mixture firmly so that the bars do not fall apart.
Cooling completely before cutting ensures ideal texture.
If you want extra crunch, add some grated coconut or seeds on top before cooking.

❌ Common mistakes:

Problem: Soft bars. Cause: Not cooling enough. Solution: Wait at least 1 hour before cutting.
Problem: Burnt on top. Cause: Fryer too hot or excessive time. Solution: Cover with aluminum foil halfway through cooking.
Problem: Sticky mixture that does not compact. Cause: Little banana or coconut oil. Solution: Add 1 more teaspoon of oil or mashed banana.
