These cookie bars combine nutty brown butter, toasted coconut, gooey toffee bits, and classic chocolate chips for a crispy-edged, chewy-centered dessert that’s dangerously easy to make and always a crowd-pleaser.

Ingredients

Scale
  • 1 cup (226g) unsalted butter, browned
  • 1 1/4 cups (250g) light brown sugar, packed
  • 1/2 cup (100g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 2 1/4 cups (280g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon fine sea salt
  • 1 cup (90g) sweetened shredded coconut (toasted if desired)
  • 3/4 cup (120g) toffee bits
  • 1 1/2 cups (270g) semisweet chocolate chips

Instructions

  1. Add butter to a medium saucepan over medium heat. Swirl occasionally as it melts, foams, and turns golden brown (about 5-7 minutes). Remove from heat and let cool for 5 minutes.
  2. Line a 9×13-inch baking pan with parchment paper, leaving overhang for easy lifting. Lightly spray with nonstick cooking spray if desired.
  3. In a large bowl, combine browned butter, brown sugar, and granulated sugar. Mix until well blended (about 2 minutes).
  4. Add eggs and vanilla extract. Mix until glossy and smooth. If butter is still warm, let it cool before adding eggs.
  5. In a separate bowl, whisk together flour, baking soda, and salt.
  6. Gradually add dry mixture to wet ingredients, stirring until just combined. Do not overmix.
  7. Stir in coconut, toffee bits, and chocolate chips until evenly distributed.
  8. Spoon dough into prepared pan and smooth out the top. Bake at 350°F (175°C) for 22-26 minutes, or until golden brown and set around the edges. The center should look slightly underbaked.
  9. Let bars cool in the pan for at least 30 minutes. Lift out using parchment overhang, then cut into squares or rectangles.
  10. For extra crispy edges, let bars cool completely before cutting.

Notes

For deeper flavor, toast the coconut before adding. Use a metal pan for crispier edges. Measure flour carefully to avoid dry bars. Brown butter adds a rich, nutty flavor—watch closely to avoid burning. Adapt with gluten-free flour or dairy-free butter and chips as needed. Bars freeze well for up to 2 months.
