Why This Recipe Works

This recipe works because browned butter adds a caramelized depth without overpowering the M&Ms’ sweetness. The salted topping balances the richness, while chilling the dough ensures even baking and chewy texture. The combination of sugars creates a perfect crisp exterior with a soft center.

My first success came from under-browning the butter, which led to burnt flavor. After mastering the amber stage, the cookies became consistently golden. Chilling the dough prevents spreading, a common issue with butter-based cookies.

Step-by-Step Instructions


  1. Preparing the Brown Butter


    Heat unsalted butter in a saucepan over medium heat. Stir constantly until it turns amber (about 10 minutes). Remove from heat immediately to avoid burning.



  2. Mixing the Wet Ingredients


    Let the browned butter cool slightly. Add granulated and brown sugar to a mixer bowl and beat on high for 2–3 minutes until fully combined.



  3. Incorporating the Egg


    Add the egg and vanilla extract. Mix on medium speed for 1 minute until well blended.



  4. Combining the Dry Ingredients


    In a separate bowl, whisk flour, baking soda, and salt. Slowly add to the wet mixture on low speed, avoiding overmixing.



  5. Adding the M&Ms


    Stir in M&Ms gently to prevent breaking them. Chill the dough for 24 hours (minimum 2 hours) to firm up.



  6. Baking the Cookies


    Preheat oven to 350°F. Line sheets with parchment. Scoop dough into 2-tablespoon mounds. Bake for 7–8 minutes for medium cookies or 9–10 minutes for larger ones.


Chef Tips for Perfect Results

  • Use a copper or stainless steel saucepan for even butter browning.
  • Bake no more than 2–3 sheets at a time to maintain oven temperature.
  • Test doneness by gently pressing a cookie: it should spring back slightly.
  • Store cookies in airtight containers with parchment paper between layers.
  • For a softer texture, underbake by 1–2 minutes and let rest on the sheet.

Common Mistakes to Avoid

1. Under-browning butter: Overly pale butter lacks depth. Monitor closely after the first 5 minutes.

2. Overmixing dough: This develops gluten, leading to tough cookies. Mix until just combined.

3. Skipping chilling: Unchilled dough spreads excessively, creating flat cookies. Always chill for at least 2 hours.

4. Overbaking: This dries out the center. Remove when edges are golden but centers are still soft.

Frequently Asked Questions

Can I use salted butter instead of unsalted?

Yes, but reduce the added salt by ¼ tsp to avoid oversalting. Adjust based on your taste.

How do I know when the cookies are done?

Press a cookie with your finger. If it springs back slightly, it’s done. Remove when edges are golden but centers are still soft.

Why are my cookies too crispy?

Overbaking is the most common cause. Reduce baking time by 1–2 minutes and let them rest on the sheet for 5 minutes.

Can I make the dough ahead of time?

Yes, chill the dough for up to 72 hours. Store in airtight container in the fridge for best results.

How should I store the cookies?

Store in a sealed container with parchment paper between layers at room temperature for 2 days or in the fridge for up to a week.

Ingredients

Scale

Unsalted butter, softened
1/2 cup (1 stick)
Granulated sugar
1/4 cup
Packed light brown sugar
2/3 cup
Large egg, room temperature
1
Vanilla extract
1 tsp
All-purpose flour
1 1/2 cups
Baking soda
1/2 tsp
Sea salt
1/2 tsp
M&Ms
1 cup
Flaky sea salt for sprinkling (optional)

Instructions

Heat 1/2 cup butter in a saucepan over medium heat. Stir constantly until melted, then brown until deep amber (10-12 minutes). Cool slightly.
In a bowl, mix browned butter with granulated and brown sugars until combined. Add egg and vanilla; mix well.
In separate bowl, whisk flour, baking soda, and 1/2 tsp sea salt. Gradually blend flour mixture into butter mixture. Stir in M&Ms until evenly incorporated.
Chill dough in sealed container for 24 hours (prevents spreading). Scoop rounded tablespoons onto baking sheets, spacing 2 inches apart.
Preheat oven to 350°F (175°C). Flatten each dough ball slightly and sprinkle with flaky sea salt. Bake 10-12 minutes until light golden. Cool on sheets before transferring to wire racks.

Notes

Use salted butter to adjust added salt (reduce by 1/4 tsp if substituting). Dark brown sugar enhances caramel flavor. Chilling is critical for preventing spread. Optional: substitute 1/4 cup buttermilk for 1/4 cup flour for extra texture.
