Ingredients
  

  • 2 cups mixed nuts almonds, cashews, pecans, roughly chopped
  • 1/2 cup raw sunflower seeds or pumpkin seeds
  • 1/2 cup old-fashioned rolled oats
  • 1/3 cup unsweetened shredded coconut optional
  • 1/2 cup honey or maple syrup for vegan option
  • 1/4 cup light brown sugar packed
  • 3 tablespoons unsalted butter or coconut oil for dairy-free
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon fine sea salt
  • 10 –12 oz dark chocolate 60–72% cocoa, chopped
  • 1 tablespoon neutral oil optional, for smoother chocolate
  • Flaky sea salt for topping

Instructions
 

  • Preheat oven to 350°F (175°C). Spread nuts and seeds on a baking sheet and toast for 8–10 minutes until lightly golden and fragrant. Let cool slightly.
  • In a large bowl, combine toasted nuts, oats, and shredded coconut. Set aside.
  • In a small saucepan over medium heat, add honey, brown sugar, and butter. Stir until melted and smooth. Simmer gently for 1–2 minutes, then remove from heat.
  • Stir vanilla extract and fine sea salt into the warm mixture.
  • Pour the binder over the nut mixture and stir until evenly coated.
  • Line an 8x8-inch pan with parchment paper. Transfer mixture to the pan and press firmly into an even layer.
  • Refrigerate for 20–30 minutes to set.
  • Melt dark chocolate using a microwave (in 20-second intervals) or double boiler. Stir in oil if using.
  • Spread melted chocolate evenly over the chilled nut base.
  • Sprinkle flaky sea salt on top while chocolate is still warm.
  • Refrigerate for another 15–30 minutes until chocolate is fully set.
  • Lift out, slice into bars, and serve.

Notes

  • Press the nut mixture firmly to prevent crumbly bars.
  • Store bars in an airtight container in the refrigerator for up to 2 weeks.
  • Freeze individually wrapped bars for up to 3 months.
  • For variations, add dried fruit, swap nuts, or use extra-dark chocolate for a less sweet bar.
  • Vegan option: use maple syrup and coconut oil, and ensure chocolate is dairy-free.
