Ingredients

Alright, let’s gather our goodies! You probably have most of these staples in your pantry already. Using room temperature ingredients, especially the butter and egg, really makes a difference in how beautifully these cookies turn out.

• 2 cups 2 Tablespoons (265g) all-purpose flour, spooned & leveled: Spooning and leveling is key here! Don’t just scoop straight from the bag, you’ll end up with too much.
• 1 teaspoon cornstarch: My little secret for that extra soft and chewy texture. Don’t skip it!
• 1 teaspoon baking soda: Helps with spread and gives them a nice lift.
• 1/2 teaspoon salt: Balances out the sweetness and enhances all those yummy flavors.
• 3/4 cup (12 Tbsp; 170g) unsalted butter, softened to room temperature: Make sure it’s genuinely soft, not melted! You should be able to press your finger into it easily.
• 3/4 cup (150g) packed light or dark brown sugar: Brown sugar is responsible for that wonderful chewiness and rich flavor. Packed is important!
• 1/2 cup (100g) granulated sugar: Adds sweetness and helps with a little crispness on the edges.
• 1 large egg + 1 egg yolk, at room temperature: The extra yolk adds richness and contributes to the soft texture.
• 1 and 1/2 teaspoons pure vanilla extract: Use the good stuff! Vanilla makes everything better.
• 1 cup mini M&Ms + 2 Tablespoons mini M&Ms for topping: Mini M&Ms distribute nicely throughout the dough, and pressing a few extra on top after baking makes them look bakery-perfect!

How to Make It

Okay, deep breaths! We’re going to walk through this step by step. It’s really simple, I promise. Just follow along, and you’ll have warm cookies in no time!

Step 1: Get Your Dry Ingredients Ready. In a medium bowl, whisk together your flour, cornstarch, baking soda, and salt. Just a quick whisk to make sure everything is combined evenly. Set this bowl aside for a moment.

Step 2: Cream the Butter. Grab a large bowl. If you have a stand mixer, fit it with the paddle attachment. A hand-held mixer works great too! Beat your softened butter on medium speed for about a minute until it’s nice and creamy. Look at that beautiful, smooth butter!

Step 3: Add the Sugars. Now, add both the brown sugar and the granulated sugar to the creamy butter. Increase the mixer speed to medium-high and beat until everything is well combined and the mixture looks light and fluffy. Don’t forget to stop and scrape down the sides and bottom of the bowl with a spatula. This ensures everything gets mixed in properly!

Step 4: Mix in the Wet Stuff. Time for the egg, egg yolk, and that lovely vanilla extract. Beat these in until they are just combined. Again, scrape down the sides and bottom of the bowl. You want that batter to be homogenous and happy!

Step 5: Combine Wet and Dry. Lower your mixer speed to low. Slowly add the dry ingredients you mixed up in Step 1 to the wet ingredients. Mix just until the flour streaks just disappear. Don’t overmix! Overmixing can lead to tough cookies.

Step 6: Fold in the M&Ms. Pour in that first cup of mini M&Ms. On low speed, beat for just about 20 seconds, or until the M&Ms are evenly distributed throughout the dough. You can even give it a final gentle fold with your spatula to make sure they’re all incorporated.

Step 7: Chill Time! This is arguably the most important step for that perfect soft-baked texture and to prevent excessive spreading. Cover your bowl of cookie dough tightly with plastic wrap. Pop it in the refrigerator for at least 2 hours. You can even chill it for up to 5 days, which is great for having fresh cookies on demand!

Step 8: Preheat Your Oven. Once your dough is properly chilled, preheat your oven to 350°F (177°C). Line your baking sheets with parchment paper or silicone baking mats. Trust me, this makes cleanup a breeze and helps with even baking.

Step 9: Roll and Place. Take out your chilled dough. Roll it into balls, using about 1.5 tablespoons of dough for each cookie. Place them on your prepared baking sheets, making sure to leave about 3 inches of space between them. They will spread a bit!

Step 10: Bake ‘Em! Slide those baking sheets into your preheated oven. Bake for 11-12 minutes. You’re looking for the edges to be lightly browned, but the centers should still look a little soft and slightly underbaked. This is the key to that soft, chewy middle!

Step 11: Cool on the Sheet. This is crucial! When they come out of the oven, leave the cookies on the hot baking sheet for 5 minutes. They continue to cook and set up during this time. If you try to move them too soon, they might fall apart.

Step 12: Add Extra M&Ms (Optional but Recommended!). While the cookies are still warm and sitting on the baking sheet, gently press those reserved 2 tablespoons of mini M&Ms onto the tops of the cookies. This makes them look absolutely gorgeous and adds extra pops of color and candy goodness.

Step 13: Final Cooling. After the 5 minutes on the baking sheet, carefully transfer the cookies to a wire rack to cool completely. Try not to sneak too many hot ones… okay, sneak just one, I won’t tell!

Substitutions & Additions

Want to mix things up? Cookies are the perfect canvas for creativity! Here are a few ideas:

• Swap the M&Ms: Try using regular-sized M&Ms, Reese’s Pieces, chocolate chips (milk, dark, white, or a mix!), or even chopped candy bar pieces.
• Add Nuts: Stir in about 1/2 to 1 cup of chopped walnuts or pecans along with the M&Ms for a little crunch.
• Get Festive: Use holiday-themed M&Ms for different occasions! Red and green for Christmas, pastels for Easter, etc.
• Sprinkles! Who doesn’t love sprinkles? You could add a few tablespoons of sprinkles to the dough or press some onto the tops with the extra M&Ms.

Tips for Success

Making cookies is fun, and a few simple tips can make sure yours turn out perfectly every time:

• Room Temperature Ingredients: I mentioned it before, but it’s worth repeating! Softened butter and room temperature eggs cream together better, creating a smoother dough.
• Don’t Overmix: Once you add the flour, mix just until combined. Overmixing develops too much gluten, leading to tougher cookies.
• Chill the Dough: Seriously, don’t skip this step! Chilling solidifies the butter, which helps the cookies spread less and creates that perfect soft-baked texture. It also deepens the flavor.
• Spoon & Level Flour: Measuring flour correctly is crucial. Spoon the flour into your measuring cup and level off the excess with a straight edge. Don’t pack it in!
• Underbake Slightly: Pull the cookies when the edges are lightly golden but the centers still look a bit soft. They will continue to cook on the hot baking sheet.
• Use Parchment or Silicone Mats: This prevents sticking and helps the bottoms bake evenly.

How to Store It

Got leftover cookies? (Wait, is that even a thing? 😉)

These Soft-Baked M&M Cookies stay wonderfully fresh covered at room temperature for up to 1 week. An airtight container or a zip-top bag works perfectly. If you’re stacking them, you can place a piece of parchment or wax paper between layers to prevent sticking.

FAQs

Here are a few questions I often get about cookie baking:

Can I skip chilling the dough?

I really don’t recommend it for this recipe. Chilling is essential for preventing excessive spread and achieving that signature soft-baked texture. If you skip it, you’ll likely end up with flatter, crispier cookies.

Why add cornstarch to the recipe?

Cornstarch is a secret ingredient for chewiness! It helps create that tender, soft center that makes these cookies so addictive.

Can I use regular size M&Ms instead of mini?

Absolutely! The mini ones distribute a little more evenly, but regular M&Ms work just fine. You might want to adjust the quantity slightly if using regulars (perhaps a bit less than 1 cup in the dough) so they don’t overpower the cookie base.

How do I know if my butter is soft enough?

Your finger should make a slight indentation when you press into it, but it shouldn’t be greasy or melted at all. If it’s too hard, pop it in the microwave for just 5-10 seconds at a time, rotating, until it’s just right. If it’s too soft, refrigerate it for a few minutes.
