Easy Air Fryer Flapjacks Recipe

Deliciously soft and chewy, easy-to-make air fryer flapjacks (also known as air fryer oat bars).

Ingredients

Scale
  • 225 g Butter
  • 100 g Demerara Sugar
  • 100 g Light Brown Sugar
  • 5 tablespoon Golden Syrup
  • 360 g Oats rolled porridge oats
  • 1 teaspoon Vanilla Extract

Instructions

  1. Preheat the air fryer to 160°C (320°F) and set the timer for 20 minutes. Grease and line a suitable baking tin with nonstick baking paper. I use a 20cm (8″) square tin in my air fryer, but you may need to use a different size tin.
  2. In a large saucepan, melt the butter, sugars and golden syrup together on a low heat, mixing with a wooden spoon to prevent it from sticking to the bottom of the pan.
    225 g Butter, 100 g Demerara Sugar, 100 g Light Brown Sugar, 5 tablespoon Golden Syrup
  3. Stir in the oats and vanilla extract.
    360 g Oats, 1 teaspoon Vanilla Extract
  4. Spoon the flapjack mixture into the prepared tin and press down firmly with the back of a spoon. Air fry for 16-20 minutes..
  5. Allow the flapjack to cool in the tin for at least 2 hours (preferably overnight), before cutting them into squares with a sharp knife.

Notes

  • Grease and line your baking tin with nonstick baking paper (parchment) to ensure the flapjacks don’t stick to the sides of the tin.
  • Use a large non-stick heavy-based saucepan to melt the butter, brown sugars, and syrup together. It must be large enough to mix the oats in too.
  • Use the back of metal spoon or spatula to press the mixture down into the lined baking tin, ensuring it’s pressed down firmly to avoid crumbling.
  • Leave the flapjacks to cool completely in the tin before cutting them into bars.
  • Pop the tin in the fridge to speed up the cooling process.
