Thick, soft, and chewy these M&M cookies are the perfect afternoon treat. You won't be able to eat just one! Step-by-step photos help you bake this delicious cookie recipe.

There is something about M&M cookies that just makes me smile. They just look like happy cookies. They make me think of being a kid and getting a colorful cookie at a school.
I love to use Christmas colored M&Ms and serve these on my Christmas cookie plate. I also add my Mexican wedding cookies and millionaires shortbread -- if you're looking for more cookie recipes!
These cookies are perfectly chewy, thick and have a slightly crisp exterior! Just the way I like them!
Let's get to the recipe.

Ingredients
- Butter. We are going to melt the butter so no need to let it sit out to soften to room temperature, woo hoo!
- Sugar. Both granulated/ caster sugar and light brown sugar.
- Eggs. Make sure they are at room temperature, so they can evenly combine with the creamed butter and sugar.
- Vanilla Extract. Use the real stuff!
- Flour. All-Purpose Flour/ Plain Flour
- Baking Soda. This chemical leavening agent makes the cookie rise and spread properly.
- Salt. Don't skip it, this helps all the flavor profile.
- Cornstarch. Also known as cornflour, this helps tenderize the cookies for a soft crumb.
- Chocolate chips. You could use chunks too. I prefer Callebaut Chocolate Callets. Semi-sweet or milk chocolate are my faves!
- M&M's. The star of the show! Use festive M&M's for holiday-inspired cookies! Next time, try my M&M Brownies.

How to make m&m cookies
Start the cookie recipe by whisking all the dry ingredients in a large bowl together.
In a large bowl or bowl of an electric stand mixer combine both sugars and the melted butter.
Next, add the vanilla extract, egg, and egg yolk.
Whisk everything together for a couple of minutes, the color of the batter will lighten.
Add the dry ingredients and gently fold them into the wet ingredients.
Next, add the chocolate chips and M&Ms
Mix until just combined. Overmixing activates the gluten, creating a tougher cookie.
The dough needs to chill for at least 30 minutes or up to 3 days. Before I chill the dough I like to scoop my cookie dough now and place it in a parchment-lined plastic container. Use a medium-size cookie scoop or scoop the dough into 1.5 tablespoon size balls.
When you are ready to bake preheat the oven to 350F/180C and line a baking sheet with parchment paper or a Silpat liner.
Place the cookies at least 2 inches apart on the baking tray. Bake the cookies for 8-11 minutes, or until the cookies are just set and turning golden brown.
If the cookie dough chills for longer than 30 minutes it will need to sit on the counter for 30 minutes before baking as the dough balls can be very cold and will not spread properly.
Can you freeze the cookies
Once you've baked the cookies allow them to cool completely then place in an air-tight container or freezer-safe bag and freeze for up to 3 months.
When ready to eat place cookies on the counter to thaw for an hour.
You can also freeze the unbaked cookie dough. To do so I scoop the cookie dough and place it on a parchment-lined sheet pan or large plate to freeze, once they are frozen (about an hour or two) place the dough balls into an air-tight container or freezer-safe bag and freeze for up to 3 months.
When ready to bake the cookies follow normal instructions but add a minute or two onto the bake time. The cookies may not spread as much from frozen, in that case when the cookies come out of the oven I bang the tray on the counter to encourage the cookies to spread.

The BEST chocolate chip cookie! Perfectly crisp on the outside, melty and chewy on the inside, and freeze super well. I scooped the dough and froze it raw, and when we wanted a treat I’d pull a couple out after dinner and bake them! Absolutely perfect!

Garry says
The dough came out extremely dry
Elizabeth Waterson says
Hi Garry, sorry about that, the flour may have been over-measured by mistake causing the dough to be dry, you could always add a splash or two of milk to moisten the dough. Hopefully that helps. XX Liz
