What kind of M&M’s should I use?

I like to use mini M&M’s because they’re a little smaller and you’ll have more M&M’s in each cookie. Instead of mini M&M’s, use 1 cup of your favorite kind.

What brand of brownie mix is best for these cookies?

For best results, I recommend using Ghirardelli Chocolate Supreme brownie mix. If you can’t find Ghirardelli, I recommend using a Pillsbury brownie mix. I don’t recommend using Duncan Hines or Betty Crocker mixes – the cookies spread way too much. If this is the only mix available, try adding ¼ cup of all-purpose flour to the mix.

Should I use the chocolate syrup that comes in the brownie box mix?

Yes, this gives the brownie cookies a more intense chocolate flavor.

Why do I need to chill the cookie dough?

This step helps the butter solidify and prevents the dough from spreading too much while the cookies bake. If the dough spreads, the cookies will be really thin instead of thick and chewy.

Kids and adults of all ages will love these rich, decadent, colorful cookies!

Trademark Note: In the spirit of transparency, I want to note that M&M’s are a trademarked product. M&M’s is a proprietary brand that I want to acknowledge and give credit to.

Tips!

  • Take the eggs out of the refrigerator about 30 minutes before making the cookie dough. Room temperature eggs incorporate more easily into the cookie dough.
  • Before serving or storing, let the cookies cool completely.
  • Keep this cookie dough on hand for whenever a chocolate craving strikes! Store it in an airtight container in the refrigerator for up to 1 week.

If chocolate is your weakness, you will adore these cookies!

Can I use chocolate chips instead of M&M’s?

M&M’s add such a fun pop of color! You can certainly use any chocolate chips if you prefer, or experiment with other candy, too.

Can I make these cookies without butter?

Yes, replace the melted butter with the same amount of vegetable oil.

How do I know when the cookies are done?

These cookies are done when the edges are just set, about 11 minutes at 350°F.

Could I make these smaller? Would the taste/texture be the same?

Is the butter melted before measurIng, or do I get 1/4 c. Unmelted Butter (which is one-half stick) and melt it?

Hi Sue, the measurement is the same either way! You shouldn’t lose a significant amount of butter to evaporation in the process of melting it.
