Ingredients
Scale
- ½ cup (113g) unsalted butter, at room temperature
- ⅓ cup (67g) granulated sugar
- ⅓ cup (73g) light or dark brown sugar
- 1 large egg yolk, at room temperature
- ½ teaspoon pure vanilla extract
- 1 cup (125g) all-purpose flour
- ¼ cup (25g) natural unsweetened cocoa powder
- ¼ teaspoon espresso powder
- ¼ teaspoon salt
- ¼ – ½ cup natural drippy tahini, for pouring
Instructions
- Preheat oven to 350°F (177°C). Meanwhile, line a large baking sheet with parchment paper or a silicone baking mat and set aside.
- In a large bowl, add the unsalted butter, brown sugar and granulated sugar. Using a hand mixer or a stand mixer, beat on medium speed until creamy, about 2 minutes. Add in the egg yolk and vanilla extract. Beat again until combined. The mixture will now be light and fluffy.
- In a separate bowl, combine the flour, cocoa powder, espresso powder and salt.
- Add the dry ingredients into the wet ingredients about 4-5 tablespoons at a time and beat on low speed until combined. Repeat until all dry ingredients are added. The cookie dough will be slightly thick.
- Beat the dough on low speed until it comes together and forms a smooth ball (see photo above). You can use your hands towards the end. However, make sure not to overmix as the butter will start melting.
- Roll the cookie dough into 1-inch balls to form 12 cookies total. Place them on the lined baking tray or mat spaced 2-inches apart. Press your thumb gently into center of each cookie to form indentation, about 1/2-inch deep.
- Allow cookies to chill in the freezer, uncovered for 30 minutes or alternatively in the refrigerator, covered for 2 hours. This is very important to avoid your cookies from over-spreading while baking in the oven.
- Bake cookies at 350°F (177°C) for 10-12 minutes or until edges start to brown. Take them out of the oven, they will be soft and moist. To get perfectly round cookies, use a large round cookie or biscuit cutter to round out each cookie immediately after they come out of the oven.
- Transfer cookies to a wire rack immediately and let them cool completely. These cookies will continue to bake while they cool.
- Spoon approximately 1/2 to 1 teaspoon tahini into center of each cookie. Refrigerate cookies until icing is just set, about 20 to 30 minutes.
- Store these cookies in an airtight container in the refrigerator for upto 1 week.
Notes
- If baking in batches, keep the remaining cookies in refrigerator instead of the freezer, until they are ready to bake.
- You can freeze these cookies before baking. Transfer the frozen dough to the refrigerator a night before you want to bake it. You can keep the frozen dough for 3 months. I do not recommend freezing the cookies after baking them.
- To get perfectly round cookies, use a large round cookie or biscuit cutter to round out each cookie immediately after they come out of the oven.
