Variations

- Stir in 1/2 teaspoon ground cinnamon for a warm, subtle spice.
Steps Overview
- Toast walnuts on a rimmed baking sheet at 350°F (175°C) for about 8–10 minutes, until fragrant. Let cool and chop.
- Melt the unsalted butter and let it cool to room temperature.
- In a medium bowl whisk together the dry ingredients: flour, cocoa powder, espresso powder (if using), baking soda, and salt.
- In a large bowl combine the brown sugar, eggs, and vanilla. Mix until smooth.
- Add the dry ingredients to the wet mixture, then pour in the room-temperature melted butter. Stir until just combined.
- Fold in the toasted walnuts or chocolate chips (or both).
- Cover the dough and refrigerate for about 45 minutes to 1 hour to firm up.
- Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
- Scoop dough into rounded tablespoon-sized balls (or use a cookie scoop), spacing them a couple of inches apart on the baking sheet.
- Bake for 9–11 minutes. To retain a fudgy interior, avoid overbaking. Let the cookies cool briefly on the baking sheet before transferring to a wire rack to cool completely.
Storage Instructions
Store baked cookies in an airtight container at room temperature for up to five days.
For longer storage, freeze cookies in an airtight container or freezer bag for up to three months. Thaw frozen cookies overnight in the refrigerator or at room temperature for a few hours.
You can also freeze individual dough balls on a baking sheet, then transfer them to a freezer bag. Bake from frozen and add one to two minutes to the baking time.
These cookies are rich, chewy, and loaded with chocolatey goodness. Bake a batch when you want an easy, crowd-pleasing dessert—perfect for sharing or enjoying with a glass of milk or a cup of coffee.
