Ingredients

Wet Ingredients

  • ½ cup (113.5 g) unsalted butter
  • 1 large egg, room temperature
  • ½ tablespoon vanilla extract

Dry Ingredients

  • 1 tablespoon espresso powder
  • ¾ cup (165 g) brown sugar
  • ¼ cup (50 g) granulated sugar
  • ¼ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 2 ¼ cups (about 280 g) all-purpose flour

Add-ins and Toppings

  • ½ cup (80 g) Heath toffee bits with chocolate
  • Flaked sea salt for topping

Instructions

  1. Brown the Butter: In a medium saucepan over medium heat, melt the unsalted butter and cook, stirring constantly, until it turns golden brown and develops a nutty aroma. This process takes several minutes; be careful not to burn the butter. Once browned, transfer the butter and the browned bits to a bowl and immediately stir in the espresso powder. Refrigerate the mixture for 1-2 hours until it firms up.
  2. Prepare the Dough: Using a stand mixer fitted with a paddle attachment, beat the chilled browned butter and both brown and granulated sugars on medium-high speed for 3-4 minutes until the mixture becomes light and fluffy.
  3. Add Egg and Vanilla: Mix in the room temperature egg and the vanilla extract, beating until everything is thoroughly combined and smooth.
  4. Incorporate Dry Ingredients: Add baking powder, baking soda, salt, and all-purpose flour to the wet ingredients. Mix on low speed just until combined, taking care not to overmix to keep the cookies tender.
  5. Fold in Toffee Bits: Gently fold the Heath toffee bits into the dough using a spatula, ensuring they are evenly distributed throughout the batter.
  6. Chill the Dough: Scoop the dough into large balls and refrigerate them for several hours, or up to 24 hours. Chilling helps the dough firm up and enhances the cookie texture.
  7. Preheat Oven & Bake: Preheat your oven to 350°F (175°C). Place the chilled dough balls on a parchment-lined baking sheet, spacing them adequately to allow for spreading. Sprinkle the tops lightly with flaked sea salt. Bake for 11-13 minutes, or until the edges are golden brown and the centers are set but still soft.
  8. Cool & Serve: Remove the cookies from the oven and let them cool slightly on the baking sheet to firm up. Then transfer them to a wire rack to cool completely before serving.

Notes

  • Browned butter adds a deep, nutty flavor – stir constantly to prevent burning.
  • Espresso powder enhances the coffee flavor without adding liquid.
  • Chilling the dough improves the texture and controls spreading during baking.
  • Use flaked sea salt sparingly to balance the sweetness and add a delicate crunch.
  • Store cookies in an airtight container at room temperature for up to 5 days.
  • Toffee bits can melt and make the cookies gooey; be sure to fold them in gently.
