Ingredients Equipment Method Notes

Ingredients
  

  • 1 cup dark chocolate chips choose good-quality for smooth melting
  • 1/4 cup unsalted butter can substitute with coconut oil for dairy-free
  • 1/4 cup honey or maple syrup adds sweetness and helps bind the mixture
  • 1 teaspoon vanilla extract enhances chocolate flavor
  • 2 cups old-fashioned oats for a chewy, hearty texture
  • Optional nuts or seeds chopped almonds, sunflower seeds, or dried fruit
  • Pinch sea salt flakes for sprinkling on top

Equipment

  • 20x20cm (8x8 inch) baking pan
  • parchment paper
  • Microwave-safe bowl
  • Spatula
  • Knife

Method
 

  1. Line your baking pan with parchment paper, leaving overhang on the sides for easy removal.
  2. In a microwave-safe bowl, combine the dark chocolate chips and butter. Microwave in 30-second bursts, stirring after each, until the mixture is smooth, glossy, and completely melted—about 1-2 minutes.
  3. Add honey or maple syrup and vanilla extract to the melted chocolate mixture, stirring until well combined and fragrant—the mixture should be shiny and smooth.
  4. Pour the melted chocolate mixture over the oats in a large bowl. Stir thoroughly with a spatula until all oats are evenly coated and shiny.
  5. If using nuts or seeds, fold them into the mixture now for added crunch and flavor.
  6. Transfer the mixture into your prepared pan. Use the spatula or the back of a spoon to press it firmly into an even layer—press down hard to help everything stick together.
  7. Smooth the top with the spatula and sprinkle with a pinch of sea salt flakes for a finishing touch.
  8. Refrigerate the pan uncovered for at least 2 hours, or until the mixture is firm and set.
  9. Once set, lift the block out of the pan using the parchment overhang. Place it on a cutting board and slice into squares or rectangles.
  10. Enjoy your chewy, chocolatey oat bars immediately or store in an airtight container in the fridge for up to a week. For softer bars, let them sit at room temperature for 10 minutes before serving.

Notes

For extra flavor, add chopped nuts or dried fruit before pressing into the pan. Use high-quality chocolate for the best texture and taste. Chill thoroughly for clean slices and a firm bite.
