Equipment

  • Stand mixer or electric hand mixer

Ingredients

  • 1 cup all-purpose flour
  • ½ cup black cocoa powder*
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ½ cup unsalted butter, room temperature
  • ½ cup light brown sugar
  • ¼ cup granulated sugar
  • 1 large egg
  • 1 Tablespoon whole milk
  • 1 teaspoon vanilla extract
  • ½ cup white chocolate melting wafers
  • Candy eyeballs, optional

Instructions

Make the cookie dough

  • In a medium bowl, add flour, cocoa powder, baking soda, and salt and whisk to combine. Set aside.
  • In the bowl of a stand mixer (or in a large bowl using a handheld electric mixer), cream the butter and both sugars until light and fluffy.
  • Add egg, milk, and vanilla to the butter mixture and beat to combine.
  • With the mixer running on low speed, slowly add the flour mixture to the butter mixture blending until combined and stopping to scrape the bowl as needed.
  • Cover the bowl with plastic wrap and place the cookie dough in the fridge to chill for 30 minutes.
  • Preheat the oven to 350°F (177°C). Line cookie sheets with parchment paper and set aside.
  • Use a 1 ½ Tablespoon cookie scoop or measuring spoons to scoop 1 ½ Tablespoon balls of cookie dough. Place cookie dough balls onto the prepared baking sheets at least 2 inches apart.

Bake the cookies.

  • Bake the cookies, one tray at a time, for 10 minutes or until the cookies are flattened with slightly puffed centers. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Melt the white chocolate.

  • When the cookies are completely cooled, melt the white chocolate wafers in a small bowl in the microwave on 50% power in 30 second increments, stirring until completely melted and smooth. 

Decorate the cookies.

  • Add the melted chocolate to a piping bag fitted with a small round piping tip (or simply use a large plastic food storage bag with one corner snipped off). Working quickly (since the chocolate will firm up as it cools), decorate the cookies.
  • To decorate mummy cookies, pipe a small drop of melted chocolate onto the back of two candy eyeballs. Affix the eyeballs just above the center of a cookie. Pipe lines of chocolate back and forth, covering each corner of the cookie, to create the mummy's wrapping.
  • To decorate spiderweb cookies, pipe a spiral of melted white chocolate onto a cookie. Using a toothpick, drag lines from the center of the cookie outward to create the spiderweb pattern.

Notes

Storage: Store cookies in an airtight container at room temperature for up to 4 days.
Freezing: These cookies can be frozen in an airtight container for up to 3 months. For best results, freeze the cookies without decorations, then defrost and decorate before serving.
*This cookie recipe calls for black cocoa powder, which creates an intensely black cookie without food coloring. Black cocoa powder is an ultra-dutched (aka alkalized or neutralized) Dutch cocoa powder, so it adds a delicate, non-bitter chocolate flavor to these cookies. I recommend King Arthur Baking black cocoa powder, which is available online.
Dutch-processed cocoa powder can be substituted for black cocoa powder in this recipe, though the resulting cookies will be a dark brown color rather than deep black. Dutch cocoa powder can be found in the baking aisle at well-stocked grocery stores, at specialty grocery stores, and online. Hershey's Special Dark cocoa powder will likely be the easiest Dutch cocoa powder to find in stores.
