Prep Time 10 minutes
Cook Time 15 minutes
Total Time 45 minutes
Servings 20 to 50 pieces, depending on size


  • ¾ cup all-purpose flour, sifted
  • ¾ teaspoon sea salt, divided
  • ¼ teaspoon baking soda
  • ¼ teaspoon espresso powder, optional, but encouraged
  • 1 cup semisweet or dark chocolate chips
  • ¼ cup unsalted butter
  • 2 egg whites, room temperature
  • 1 teaspoon pure vanilla extract
  • ¾ cup granulated sugar
  • 3 tablespoons cocoa powder
  • cup toffee bits, divided
  • ¼ cup mini chocolate chips, divided


  • Preheat oven to 350°F and line a large baking sheet with a nonstick silicon mat or parchment paper.
  • In a medium bowl, whisk together flour, ¼ teaspoon salt, baking soda and espresso powder. Set aside.
  • In a large microwave safe bowl, combine butter and 1 cup chocolate chips. Heat for 30 seconds and stir. Heat in 15 second increments, stirring after each, until melted, smooth and combined.
  • Add sugar and cocoa powder and stir to combine.
  • Add egg whites and vanilla, and stir again to combine.
  • Add flour mixture to chocolate mixture and stir until completely combined.
  • Add ⅓ cup toffee bits and 2 tablespoons mini chocolate chips and stir to combine.
  • Use a spatula to spread the batter in an event, thin layer on prepared baking sheet.
  • Sprinkle the top with remaining ½ teaspoon salt, ⅓ cup toffee bits and 2 tablespoons mini chocolate chips.
  • Bake for 15 minutes or until it's cooked through (like a normal brownie consistency). Remove from the oven and carefully slice into squares and/or triangles.
  • Turn off the oven and place the brownies back into the oven and let them continue to bake as the oven cools. Check in every 5 minutes to make sure they're not burning - you want them to crisp, not burn!
  • Remove from oven and let cool completely before serving and/or storing. Enjoy!
