These rich, chocolatey cookies are soft, chewy, and full of that classic homemade brownie flavor—made simple with a cake or box mix. They’re the kind of easy Christmas treat everyone looks forward to baking year after year.
Preheat oven to 350ºF. Line a baking sheet with parchment paper.
Add the brownie mix, flour, and instant coffee to a large mixing bowl and whisk until well combined.
Add the eggs and vegetable oil and mix well. Fold the chocolate chips in. The batter will be thick.
Scoop 1-2 tablespoons of the cookie dough and shape into a ball using your hands.
Pour the powdered sugar into a bowl. Roll each cookie dough ball in the powdered sugar until it is fully covered. Place the sugared balls 1 inch apart on the prepared baking sheet.
Bake in the preheated oven for 11-13 minutes. (11 for soft and chewy cookies, 13 for cookies similar to the edges of a pan of brownies)
Remove the cookies from the oven and transfer to a wire rack to cool.
