If you've ever been disappointed by homemade cookie recipes that turn out flat, hard, or just nothing like the gorgeous ones in bakery display cases, you're going to love these bakery-style soft-baked M&M cookies. After weeks of testing and tweaking (someone had to eat all those test batches!), I've perfected a recipe that delivers incredibly soft, thick cookies that stay that way for days. These aren't your average M&M cookies - they have that perfect balance of slightly crisp edges and soft, almost underbaked centers that professional bakeries are known for. The best part? The secret techniques are surprisingly simple, and I'm sharing every last detail so you can recreate that bakery magic in your own kitchen.
The result is pure cookie magic - thick, puffy cookies that stay soft in the middle like they just came out of the oven, and the M&Ms add those perfect pops of chocolate and color that make everyone grab seconds (or thirds, no judgment here). These are your new go-to cookies for impressing literally anyone - school bake sales, holiday cookie exchanges, office parties, or just treating yourself on a random Thursday night. Because let's face it, we all deserve bakery-quality cookies without actually having to put on pants and go to a bakery.
The Secret to Perfect Soft-Baked Cookies
These cookies stay irresistibly soft thanks to four key techniques working together.
- Extra Egg Yolk: The extra egg yolk adds richness and moisture to the dough, while its natural emulsifiers create that tender, melt-in-your-mouth texture we all crave.
- Cornstarch: A teaspoon of cornstarch works magic by inhibiting gluten development and creating a more delicate crumb structure.
- Oven Temperature: The lower oven temperature of 325°F allows the cookies to bake more slowly and evenly, preventing the edges from crisping before the centers set.
- Dough Shape: Shaping the dough into tall mounds rather than balls ensures the cookies spread more slowly during baking, maintaining thickness and allowing the centers to stay perfectly soft and slightly underdone.
Together, these techniques create cookies with crisp edges and pillowy centers that stay soft for days!
How to Make Soft-Baked M&M Cookies
Bakery-Style Soft-Baked M&M Cookies
Ingredients
- 170 g unsalted butter melted
- 150 g light brown sugar
- 67 g granulated sugar
- 1 large egg
- 1 large egg yolk
- 1 tablespoon vanilla bean paste
- 250 g all-purpose flour
- 1 teaspoon cornstarch
- ¾ teaspoon baking soda
- ½ teaspoon fine sea salt
- 200 g M&M'S minis divided
Instructions
- In a large mixing bowl, whisk together the melted butter, dark brown sugar, and granulated sugar until well combined.
- Add the egg, egg yolk, and vanilla and whisk until incorporated.
- Add the flour, cornstarch, baking soda, and salt to the wet ingredients and mix until just combined; be sure not to overmix! Fold in most of the mini M&M'S (reserve some for the next step) until incorporated.
- Using a medium (1½-tablespoon) spring-loaded scoop, take heaping scoops of the dough, form into tall mounds, and then place on a lined baking sheet. Top with remaining M&M'S, then loosely cover with plastic wrap and place in the refrigerator to chill for 30-60 minutes.
- Preheat the oven to 325°F (165°C). Line another baking sheet with parchment paper and set aside.
- Bake the cookies for 12-13 minutes, or until lightly browned on the sides; the centers will look very soft. Remove from the oven and allow to cool on the baking sheet completely.
