Ingredients

Dry Ingredients

  • 1 ¼ cups (155 g) all-purpose flour

  • ½ cup (40 g) dark cocoa powder (or black cocoa)

  • ½ tsp baking powder

  • ½ tsp baking soda

  • ½ tsp fine sea salt

Wet Ingredients

  • ¾ cup (170 g) unsalted butter, softened

  • ¾ cup (160 g) packed light brown sugar

  • ¼ cup (50 g) granulated sugar

  • 2 large egg yolks, room temperature

  • 1 tsp pure vanilla extract

Mix-ins & Decorations

  • ¾ cup (170 g) Halloween-colored M&M’s

  • 3 tbsp festive sprinkles (orange, purple, green, black)

  • Candy eyeballs for decoration

  • Extra M&M’s and sprinkles for topping


Instructions

1️⃣ Preheat the Oven
Preheat oven to 350°F (175°C) and line two baking sheets with parchment paper.

2️⃣ Mix Dry Ingredients
In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.

3️⃣ Cream Butter & Sugars
In a large bowl, beat softened butter with brown sugar and granulated sugar until light and fluffy, about 2 minutes.

4️⃣ Add Egg Yolks & Vanilla
Mix in egg yolks and vanilla extract until smooth.

5️⃣ Combine Wet & Dry
Gradually add dry ingredients to wet mixture, stirring just until combined.

6️⃣ Fold in the Fun
Fold in M&M’s and sprinkles with a spatula until evenly distributed.

7️⃣ Shape the Cookies
Scoop 2 tablespoons of dough per cookie onto prepared sheets, spacing 2 inches apart. Press extra candies and candy eyeballs on top.

8️⃣ Bake & Cool
Bake for 10–12 minutes until edges are set but centers remain soft. Cool on baking sheet 5 minutes, then transfer to wire rack.

📌 Pro Tip: Use a round cutter to shape cookies into perfect circles while still warm.

Notes

  • Chill dough for thicker cookies.

  • Add candy eyeballs after baking if you want them extra defined.

  • Store baked cookies in an airtight container for 5 days or freeze dough balls for up to 3 months.
