Baked in the air fryer, these bars are quick to make, and the result is a soft, chewy treat that’s perfect for breakfast or a snack!
Ingredients:
- 2 ripe bananas, mashed
- 2 large eggs
- Porridge oats (add until you reach a thick batter consistency)
- 1-2 teaspoons chia seeds (optional, for added nutrition)
- 2 teaspoons crunchy peanut butter
- 2 teaspoons Nutella (plus more for drizzling)
- 1-2 Twirl chocolate bars (or any chocolate bar of your choice), broken into pieces
- Milk (optional, to loosen the batter)
- Greaseproof or parchment paper (for lining)
Instructions:
- Prepare the Mixture: In a large bowl, mash the ripe bananas until smooth. Add in the eggs, peanut butter, and Nutella. Mix well. Gradually add the oats, stirring until you reach a thick batter consistency. Add chia seeds if using, and if the mixture feels too thick, add a little milk to loosen it.
- Prepare the Air Fryer: Line the bottom of your air fryer basket with greaseproof or parchment paper. Trim the paper to fit the basket.
- Mix in the Chocolate: Stir the broken Twirl chocolate pieces into the batter, ensuring they’re evenly distributed.
- Cook the Bars: Pour the mixture into the air fryer basket and spread it out evenly. Set the air fryer to 150°C (300°F) and bake for 20-25 minutes, checking on it occasionally to avoid over-baking. The bars should be golden and firm to the touch.
- Optional – Drizzle with Nutella: Once the bars are done, remove them from the air fryer and let them cool for a few minutes. Melt a little more Nutella and drizzle it over the top for an extra chocolatey finish.
- Slice and Enjoy: Once cooled, slice the bars into squares or rectangles. Enjoy these soft, chewy, and indulgent banana oat bars!
