Delightfully spooky Slime Filled Halloween Cookies featuring rich cocoa dough studded with colorful M&Ms and filled with bright neon green frosting to create a fun and playful treat perfect for Halloween celebrations.

Ingredients

Cookie Dough

  • 1 Cup Sweet Cream Unsalted Butter
  • 3/4 Cup Sugar
  • 2/3 Cup Packed Brown Sugar
  • 2 Eggs (large)
  • 1 tsp Vanilla Extract
  • 2 1/4 Cup All-Purpose Flour
  • 2/3 Cup Unsweetened Cocoa Powder
  • 1 tsp Baking Soda
  • 1/4 tsp Salt
  • M&M Candies (orange, green, and purple), quantity as desired

Filling

  • 16 oz White Frosting (typically one container)
  • 5 drops Neon Green Gel Food Coloring

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the cookies.
  2. Prepare Baking Sheet: Line a cookie sheet with parchment paper or a non-stick silicone baking mat for easy removal and cleanup.
  3. Separate M&Ms: Divide the green, orange, and purple M&M candies into a small bowl to use later.
  4. Mix Dry Ingredients: Sift together the flour, baking soda, salt, and cocoa powder in a mixing bowl to ensure even distribution and remove lumps.
  5. Cream Butter and Sugars: In a separate large mixing bowl, use an electric mixer to cream the unsalted butter, sugar, and brown sugar together until light and fluffy.
  6. Add Eggs and Vanilla: Beat in the eggs one at a time along with the vanilla extract until fully incorporated.
  7. Combine Ingredients: Gradually add the dry ingredients to the wet mixture, mixing continuously until a uniform dough forms.
  8. Incorporate M&Ms: Stir about half of the separated M&M candies into the cookie dough for colorful bursts inside the cookies.
  9. Form Dough Balls: Roll the dough into balls approximately 2 inches in diameter.
  10. Press M&Ms on Dough: Press the remaining M&Ms into the surface of each dough ball to decorate.
  11. Bake Cookies: Place dough balls on the prepared baking sheet and bake at 350°F for 9-11 minutes. Remove when edges are set but centers are still slightly soft.
  12. Cool Cookies: Let the cookies cool slightly on the baking sheet before transferring them to a wire rack to cool completely.
  13. Prepare Frosting Filling: Scoop the white frosting into a microwave-safe bowl and heat for 15 seconds to soften it for easier injection.
  14. Color the Frosting: Stir in 5 drops of neon green gel food coloring until the frosting turns bright green, resembling slime.
  15. Fill Injector: Using a flavor injector with a needle, draw the green frosting into the injector chamber.
  16. Inject Frosting: Poke the side of each cooled cookie with the injector needle and slowly inject the green frosting until the top cracks slightly, filling the inside with slime.
  17. Repeat Filling: Continue injecting all cookies until each is filled with the neon green frosting slime.

Notes

  • Use parchment paper or a silicone mat to prevent cookies from sticking and for easy cleanup.
  • Adjust baking time if using larger or smaller cookie dough balls to avoid under/overbaking.
  • If you don’t have a flavor injector, carefully cut a small hole in the side of the cookie to fill with frosting using a piping bag or small spoon.
  • Ensure frosting is softened but not runny for best injection results.
  • Store cookies in an airtight container at room temperature for up to 3 days to maintain freshness.
