Cream together the unsalted butter, light brown sugar, and granulated sugar until light and fluffy. Mix in the eggs and vanilla extract.
Add in the flour, black cocoa powder, baking soda, and salt. Mix until the dough forms. Lastly, fold in the chocolate chips.
Using a medium cookie scoop, scoop dough and place onto a baking sheet. Once all the dough is scooped, place the tray in the fridge and chill the dough for one hour.
Once the dough has chilled for an hour, preheat your oven to 350°F. Line 2 baking sheets with parchment paper. Roll the chilled dough into balls and place them a few inches apart on the baking sheets.
Bake the cookies for 12-14 minutes. Once out of the oven, cookies should be slightly puffy and look slightly underdone in the middle. Allow the cookies to cool for about 5 minutes, then transfer them to a cooling rack to cool completely.
Melt the white chocolate in the microwave in 30 second increments, stirring after each one. Pour the melted chocolate into a piping or zip top bag. Cut a tiny bit off one of the bottom corners.
Drizzle the white chocolate in alternating directions on the top half of each cookie. Place the candy eyes on the melted chocolate. Allow the white chocolate to set. Enjoy!
