Line your pan with parchment paper, leaving overhang for easy removal.
Combine the chopped chocolate and honey in a heatproof bowl.
Set the bowl over a saucepan with simmering water and stir gently until the mixture is smooth and shiny, about 3-5 minutes.
Remove from heat and stir in the warm melted butter, vanilla extract, and a pinch of sea salt until well combined.
Stir in the oats and chopped nuts, mixing thoroughly so every bit is coated with the chocolate mixture.
Pour the mixture into your prepared pan and use a spatula to spread it out evenly, pressing down firmly to compact the mixture.
Tap the pan lightly on the counter to settle the mixture further and remove air pockets.
Place the pan in the refrigerator and chill for at least 2 hours, or until the mixture is firm and crackly on top.
Once set, lift the bars out of the pan using the parchment overhang and transfer to a cutting board.
Slice into squares with a sharp knife dipped in hot water for clean, smooth cuts.
Serve immediately or store in an airtight container in the fridge for up to a week. Enjoy these chewy, chocolatey bites whenever you need a quick treat!
