Chocolate M&M Cookies

02/04/2026 | Bonia Bakery |

There’s something especially comforting about a good chocolate cookie. Deep, rich cocoa flavor, a soft and chewy center, and just enough structure around the edges to hold everything together. This recipe leans into that classic texture while adding a playful, festive twist thanks to colorful M&M’s.

Because let’s be real here.. who doesn’t love a good M&M cookie?

Whether you’re using Valentine’s Day reds and pinks or swapping in soft pastel colors for Easter, these cookies instantly feel celebratory and perfect for any occasion.

Each cookie is portioned carefully so they bake evenly, giving you thick, bakery-style cookies that feel special without being complicated. Measuring the dough and pressing the M&M’s onto the outside may seem like a small step, but it makes such a difference in the final look.

The cookies bake up beautifully, with the candy coating the surface instead of disappearing into the dough—making those bright colors really stand out.

The dough itself comes together quickly and doesn’t require any chilling, which makes this recipe perfect for last-minute baking. Creaming the butter and sugars until light and fluffy helps create that soft, chewy texture, while the cocoa powder adds a rich chocolate base that balances perfectly with the sweetness of the M&M’s. The key is not overmixing once the flour is added—this keeps the cookies tender and prevents them from becoming dry or dense.

These cookies are perfect for packaging up in little treat bags, adding to a dessert spread, or enjoying with a glass of milk or a hot cup of coffee. They’re festive without being fussy, sweet without being overwhelming, and exactly the kind of homemade treat that feels thoughtful and comforting—whether you’re baking for Valentine’s Day, Easter, or just because.

Sometimes the best way to celebrate—any kind of love or even just the season—is with a homemade dessert and a little extra chocolate. And these chocolate M&M cookies are always a good place to start💛🍪

Ingredients

Makes 12 cookies

  • 113 grams unsalted butter, softened (½ cup)
  • 75 grams granulated sugar (6 tablespoons)
  • 73 grams brown sugar (⅓ cup, packed)
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 140 grams all-purpose flour (about 1⅛ cups)
  • 33 grams unsweetened cocoa powder (⅓ cup)
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 170 grams M&Ms (½ standard bag)

Instructions

  1. Preheat the oven
    Preheat your oven to 350°F (180°C). Line a baking sheet with parchment paper and set aside.
  2. Mix the dry ingredients
    In a medium-sized bowl, whisk together the flour, cocoa powder, baking soda, and salt until well combined. Set aside.
  3. Cream the butter and sugars
    In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2 minutes.
  4. Add the egg and vanilla
    Add the egg and vanilla extract and beat until fully incorporated and smooth.
  5. Combine wet and dry ingredients
    Add the dry ingredients to the wet ingredients, mixing just until incorporated. Be careful not to overmix—overmixing will result in tough, dry cookies.
  6. Portion the dough
    For evenly sized cookies, measure 1.8 ounces (about 51 grams) of dough per cookie using a food scale. Roll each portion into a smooth ball and place on the prepared baking sheet, leaving space for spreading.
  7. Add the M&Ms
    Press the Valentine’s Day M&Ms all around the outside of each dough ball. Make sure the entire surface is covered so the M&Ms stay visible after baking.
  8. Bake
    Bake for 9–11 minutes, or until the edges are set and the tops look slightly cracked. The centers will still be soft.
  9. Cool
    Allow the cookies to cool completely on the baking sheet before transferring or storing.

Bake Ahead & Storage Tips

Bake Ahead:

  • The cookie dough can be rolled into balls and stored in an airtight container in the refrigerator for up to 24 hours before baking.
  • Let chilled dough sit at room temperature for about 10 minutes before baking for even spreading.

Freezing:

  • Unbaked dough balls can be frozen for up to 2 months. Freeze first on a baking sheet, then transfer to a freezer-safe bag. Bake straight from frozen, adding 1–2 minutes to the bake time.

Storage:

  • Store baked cookies in an airtight container at room temperature for up to 4 days.
  • For best texture, keep them in a single layer or separate layers with parchment paper.
