  • Prep Time: 15 minutes
  • Chill Time: 6 hours
  • Cook Time: 15 minutes
  • Total Time: 6 hours 30 minutes
  • Servings: 36 cookies


  • ¾ cup butter, softened
  • ¾ cup brown sugar
  • ½ cup granulated sugar
  • 1 large egg
  • 1 yolk
  • 2 teaspoons vanilla extract
  • 2 ¼ cups all-purpose flour
  • 2 teaspoons cornstarch
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup mini M&Ms
  • ½ cup chopped compound chocolate
  • ¼ cup rainbow sprinkles


In a mixer bowl, mix together the softened butter, brown sugar, and granulated sugar until creamy. Then add in the egg, the yolk and the vanilla extract, and keep mixing until well combined.

In a separate bowl, sift together the flour, starch, baking soda and salt. Gradually add the dry ingredients to the wet ones, and mix until you get a dough. Fold in the mini M&Ms, chopped chocolate, and rainbow sprinkles with the help of a spatula until evenly distributed. Cover the dough and transfer to the fridge for about 6 hours (or best overnight).

When it’s time to bake the cookies, preheat the oven to 350°F and line your baking tray with parchment paper. Using a cookie scoop (or an ice cream scoop), portion the dough onto the prepared baking tray, leaving some space between them. Optionally, add extra chunks of chocolate, sprinkles and M&Ms onto the cookies dough for a decorative touch.

Bake in the preheated oven for about 12 to 14 minutes or until the edges of the cookies start to turn golden brown.

Remove the cookies from the oven and allow to cool for a few minutes before serving.

Storage tips:

Store cooled cookies in an airtight container at room temperature for up to 5 days.

For longer storage, freeze the cookies in a single layer, then transfer them to a freezer bag or container. They can be frozen for up to 3 months. Thaw at room temperature before serving.

Elevate the nutritional profile of your chocolate chip and sprinkle cookies with M&Ms by making simple ingredient swaps that prioritize health without compromising on taste. Opting for high-quality allergen-free compound chocolate instead of regular chocolate chips not only reduces the risk of allergen exposure but also enhances the richness of flavor. Compound chocolate contains fewer additives and preservatives, providing a cleaner alternative for those with dietary sensitivities.

Also, choose natural-colored sprinkles over those containing artificial dyes to infuse your cookies with vibrant hues without synthetic additives. These natural sprinkles offer the same eye-catching appeal while minimizing the intake of artificial ingredients, making your indulgence a guilt-free delight.

Make these healthier, delicious and appealing cookies for any occasion, and you’re sure to win over any kid or guest!
