Ingredients Equipment Method Notes

Ingredients
  

  • 200 g dark chocolate good quality for smooth melting
  • 100 g butter salted or unsalted as preferred
  • 2 tbsp honey or golden syrup for sweetness and shine
  • 1 tsp vanilla extract brightens flavor
  • 2 cups rolled oats toasted for extra flavor

Equipment

  • 20x20cm (8x8 inch) square pan
  • Spatula
  • Saucepan
  • Mixing bowl
  • parchment paper

Method
 

  1. Line your square pan with parchment paper, leaving overhang on the sides for easy removal.
  2. In a saucepan over low heat, melt the dark chocolate and butter together, stirring gently until the mixture is glossy and smooth, about 3-4 minutes.
  3. Remove the saucepan from heat, then stir in honey (or golden syrup) and vanilla extract until fully incorporated and shiny.
  4. In a mixing bowl, toast the oats lightly in a dry pan until fragrant and golden, then transfer to a large mixing bowl.
  5. Pour the melted chocolate mixture over the toasted oats, then stir thoroughly until all the oats are coated and sticky.
  6. Transfer the mixture into your prepared pan, pressing down firmly with the spatula to create an even, compact layer.
  7. Place the pan in the fridge and chill for at least 2 hours until the slice is set and firm.
  8. Once chilled, lift the slice out of the pan using the parchment overhang. Slice into bars or squares, about 1 inch wide.
  9. Let the slices sit at room temperature for 10 minutes to soften slightly, then enjoy the chewy, chocolatey goodness.

Notes

For a vegan version, substitute dairy-free chocolate and coconut oil. Toast oats before mixing for extra flavor, or add nuts/dried fruit for variety. Keep refrigerated for up to 5 days or freeze for longer storage.
