These EYE-catching Halloween monster cookies are super soft and chewy. Kids and grown ups alike will find them monstrously fun with their vibrant colors, M&Ms and wacky eyeball sprinkles.


  • 2 3/4 cups (358g) all-purpose flour (measured correctly)
  • 1 tsp baking soda
  • 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1 cup (224g) unsalted butter, room temperature
  • 1 cup + 2 tbsp (233g) granulated sugar
  • 2 tbsp (28g) light brown sugar
  • 1 large egg
  • 2 tsp vanilla extract
  • Green, Orange and Purple gel icing color
  • Green, Orange and Purple sanding sugar, optional
  • Eyeballs
  • M&Ms


  1. Preheat oven to 350°F (180°C). Line baking sheets with parchment paper or silicone baking mats. Set aside.
  2. Combine the flour, baking soda, baking powder and salt in a medium sized bowl and set aside.
  3. Cream the butter and sugars together in a large mixer bowl on medium speed until light in color and fluffy, 2-3 minutes. You should be able to see the change in color happen and know it’s ready.
  4. Add the egg and mix until well combined.
  5. Add the vanilla extract and mix until well combined.
  6. Add the dry ingredients and mix until the dough is well combined. It will be thick and shouldn’t be sticky. Do not over mix. Once it’s well combined, use a rubber spatula to help it come together to form a more cohesive ball.
  7. Divide the cookie dough evenly between three bowls. Color one with green gel icing color, one with orange gel icing color and one with purple gel icing color. The less coloring you add, the better. You don’t want to add too much more moisture or your cookies will spread too much.
  8. Create 1 1/2 tablespoon sized balls of cookie dough. Gently roll into a ball, then roll each ball in the optional sanding sugar to coat. I find that the sanding sugar can make it harder for the eyeballs and M&Ms to stick later, so you don’t have to use it. Set the balls on the baking sheet.
  9. Bake cookies for 7-8 minutes. The cookies will spread and the centers will look soft, but should look done. Remove just before the edges begin to turn golden. Don’t over bake.
  10. Remove from the oven and immediately press eyeballs and M&Ms into the cookies, as desired. The heat from the warm cookies will melt the candy coatings just a bit and help them adhere to the cookies.
  11. Allow to cool on baking sheets for 4-5 minutes before transferring to a wire rack to cool completely.
