Ingredients You’ll Need
How to Make the Cookies
- Preheat the oven to 350 F and line cookie sheets or leave unlined if you prefer a slightly crisper bottom.
- In the bowl of an electric mixer, combine the butter and sugar. Beat together on medium-high speed until light and fluffy, 2-3 minutes—this aerates the dough and helps create tender, slightly crisp edges.
- Blend in the eggs one at a time, scraping down the bowl as needed. Mix in the dark cocoa powder (regular cocoa powder can be used) until well blended and evenly colored.
- Add the all-purpose flour, coarse salt (regular salt can be used), and baking powder to the bowl. Mix on low speed just until the dry ingredients are incorporated; avoid overmixing to keep the cookies tender.
- Fold in the Holiday M&Ms and chocolate chips with a spatula until distributed evenly through the dough.
- The dough may be thick—stir with the spatula until just combined so you don’t overwork it.
- Using a standard size cookie scoop, portion the dough onto cookie sheets. To make 36 cookies, place about 12 cookies on each sheet so they have room to spread.
- Bake for approx 10 minutes. Remove from the oven when the edges are set but centers still look slightly soft for chewy cookies.
- Let cookies cool on the cookie sheets for 5-10 minutes, then transfer to a wire rack to cool completely. Store cooled cookies in an airtight container.

Keep the Cookies Chewy
Chewy centers come from slightly underbaking and the resting step: pull the cookies when the edges are set but the middles still look soft, then cool on the sheet for 5-10 minutes.
Avoid overmixing once you add the flour—overworked dough yields denser cookies.
- Remove at approx 10 minutes when edges are set but centers are still soft.
- Cool 5-10 minutes on the cookie sheet before moving to a wire rack.
- Don’t overmix after adding flour; fold gently to combine.
Freeze & Reheat Tips
This dough freezes well, as do the baked cookies. Freeze scooped dough balls on a tray, then transfer to a freezer bag for longer storage. Baked cookies keep in the freezer in an airtight container too.
Reheat baked cookies briefly in a 300 F oven or microwave in 10–15 second bursts to refresh the chew and soften the chocolate.
- Freeze scooped dough balls on a tray until firm, then store in a freezer bag for up to 3 months.
- Bake frozen dough balls from frozen; add a couple of minutes to the bake time and watch for edge-setting.
- To refresh baked cookies: warm in a 300 F oven for 4-6 minutes or microwave for 10–15 seconds.
Fun Decorating Ideas
Keep decorating simple and kid-friendly: press extra M&Ms onto warm cookies, use seasonal colorways, or add a few Halloween sprinkles.
For playful faces, use two M&Ms for eyes and a small line of chocolate chips or icing for a mouth.
- Press a few extra M&Ms into the warm cookie surface right after baking for a shiny, colorful top.
- Use only Halloween-colored M&Ms or mix in edible candy eyes for spooky faces.
- Drizzle a little melted white chocolate over cooled cookies for contrast and extra decoration.
Baker’s Tips
Bake time matters: Aim for approx 10 minutes and remove when edges are set but centers are soft—cookies firm up during the 5-10 minute cooling on the sheet.
Portioning: A standard cookie scoop yields the count in this recipe (Servings 36 Cookies). Placing about 12 per sheet gives each cookie room to spread.
Candy placement: Press a few extra M&Ms onto the tops right after scooping or after baking for a picture-perfect look and brighter color.
