Ingredients Equipment Method Notes

Ingredients
  

  • 200 g dark chocolate chopped finely for easier melting
  • 2 cups rolled oats for chewy texture
  • 1/4 cup honey or golden syrup acts as a binder and sweetener
  • 1 teaspoon vanilla extract brightens the flavor
  • a pinch salt enhances chocolate flavor

Equipment

  • 20cm (8-inch) square tin
  • Saucepan
  • Mixing bowl
  • Spatula
  • Baking paper
  • Sharp knife

Method
 

  1. Line the square tin with baking paper, allowing some overhang for easy removal.
  2. Place the chopped dark chocolate in a saucepan and melt over low heat, stirring gently until smooth and glossy. Keep the heat low to prevent burning and listen for a gentle bubbling.
  3. In a large mixing bowl, combine the rolled oats, honey or golden syrup, vanilla extract, and a pinch of salt. Mix well until the oats are evenly coated and sticky, feeling slightly tacky to the touch.
  4. Pour the melted chocolate into the bowl with the oats mixture. Use a spatula to fold everything together, making sure each oat is coated in chocolate and the mixture becomes glossy and thick.
  5. Transfer the mixture into the prepared tin. Press down firmly with the back of a spatula or your hands to create an even, compact layer. Smoothing the top helps it set evenly.
  6. Place the tin in the fridge and chill for at least 2 hours, or overnight if you have time. The mixture will firm up, and the chocolate will set to a shiny finish.
  7. Once set, lift the slice out of the tin using the overhanging paper. Place on a cutting board and use a sharp knife to slice into squares or rectangles of your preferred size.
  8. Wipe the knife with warm water between cuts to keep slices neat and clean. Serve immediately or store in an airtight container in the fridge for up to a week.

Notes

For added texture, fold in chopped nuts or dried fruit before pressing into the tin. To make it dairy-free, substitute coconut oil for butter or use vegan dark chocolate.
