Bake fun, festive & feisty monster cookies for your upcoming Halloween party!


  • 1/2 cup (1 stick) unsalted butter, room temperature
  • 1/2 cup granulated sugar
  • 1/4 cup brown sugar
  • 1 large egg
  • 1/2 teaspoon vanilla
  • 1 cup all-purpose flour
  • 1/4 cup dark cocoa powder
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon kosher salt
  • 1 (12 ounce) bag mini multi-colored chocolate covered candies
  • 30 bite-sized vanilla cream-filled cookie sandwiches
  • 1 pouch white decorator’s cookie icing


  1. In the bowl of an electric mixer, beat the butter and sugars until smooth. Add the egg and vanilla and beat until well combined.
  2. In a separate bowl, whisk together the flour, cocoa, baking powder, baking soda, and salt. Add the flour mixture to the wet ingredients in two batches and beat on low speed until just combined. Cover and refrigerate dough for 1 hour.
  3. Meanwhile, sort multi-colored candies by color. Separate the sandwich cookies from each other and press one of the brown colored candies into the center of the cream side of each cookie so that it looks like an eyeball.
  4. Preheat oven to 350°F.
  5. Remove cookie dough from the refrigerator. Form dough into 2-tablespoon sized balls and place a few inches apart on a parchment lined baking sheet. Flatten each ball of cookie dough slightly with the palm of your hand. Press about 15 of the same colored candies (except for the brown ones) into the top of each cookie. Alternate colors among the cookies so you have a good variety.
  6. Bake for about 10 minutes or until cookies start to crinkle a bit on top and are set around the edges. As soon as you remove the cookies from the oven, press one or two of the cookie eyes into the top of the cookies where there are gaps in the mini candies. Let cool completely on cookie sheets, about 20 minutes.
  7. Make fun mouth shapes with the cookie icing. Have fun & enjoy!
