1/2 cup Halloween-themed sprinkles (purple, green, and orange)
48 edible candy eyes
Instructions
Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats to prevent the cookies from sticking and ensure even browning.
In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until the mixture is light and fluffy. This usually takes about 2 to 3 minutes with an electric mixer.
Add the egg and vanilla extract to the butter mixture. Beat on medium speed until well combined, making sure to scrape down the sides of the bowl with a spatula.
In a separate medium bowl, whisk together the flour, dark cocoa powder, baking soda, and salt. Gradually add these dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
Gently fold in the chopped Oreo pieces and half of the Halloween sprinkles using a spatula. This ensures every cookie is packed with chocolatey crunch and festive color.
Scoop rounded tablespoons of dough (about 2 tablespoons per cookie) and place them 2 inches apart on the prepared baking sheets. Bake for 9 to 11 minutes, or until the edges are set but the centers still look slightly soft.
Immediately after removing the cookies from the oven, press the remaining sprinkles and the edible candy eyes into the tops of the warm cookies. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
