M & M Brownie Cookies

We get oodles of trick or treaters at our door. I love to buy a variety of full-sized candy bars…and when my kids were little, I let them select one for themselves before the doorbell started ringing. Katie and Tom would choose Reese’s Peanut Butter Cups and Nick was more likely to pick Skittles. The hubby, my 4th kid, liked to confiscate some M&M’s or 3 Musketeers Bars. And I liked to set aside some of the candy that works well in cookies…and here’s where I reach for the M&M’s, too.

What to Do with Leftover Halloween Candy

At Easter, the white chocolate egg-shaped M&M’s go into brown butter M&M cookies, but at Halloween, I think brownie cookies dotted with classic M&M’s are perfect for my own goblins. A combination of white and dark chocolate chips works well in these brownies in cookie form, too. No matter which option you chose, these M&M Brownie Cookies will definitely be a crowd-pleaser. These chewy Classic M & M Cookies are also winners!

A couple of things to help you make the M&M Brownie Cookies recipe:

Half Sheet Baking Pan

Medium Cookie Scoop

Tip of the Day: When making M&M cookies, reserve a few to add to the top of the cookies immediately after they come out of the oven for a prettier presentation.

  4. Brownie cookies sound good! I’ve been looking at the candy corn M&M’s this year:@)

  5. These brownie cookies look so pretty! Love how colorful they look with the M&M’s! I usually reach for M&M’s too when I sneak a bite of our candy that we give away 🙂

  6. Would you believe, I live in a lovely little neighborhood, and yet only get like two trick or treaters. Crazy right? So I gave up and just get the candy hubby and I want, more for us LOL! I love the idea of a brownie cookie, they look and sound fabulous! Hugs, Terra

  7. oh wow–this looks amazing! i love M&M

  8. The word is out now! All the kids are heading to Liz’s house to trick or treat!!! Love these fun and vibrant M and M cookies. I am hoping the boys leave me some of their trick or treat m and m candies so I can make your cookies.

  9. Lizzy , I couldn’t help but grin re the 4th kid ! Your cookies look wonderful ( as always ! )

  10. chocolaty goodness, yes! Your cookies make me smile Liz. =)

  11. My kids would adore these… who doesn’t love an M&M. 🙂

  12. What a fun presentation!!! These cookies look so delish, Liz!

  13. We don’t get many trick or treaters here in the city and that’s a HUGE problem…for me. 🙂

  14. I think I may come to your house to trick or treat! These are totally up my alley!

  15. Full size candy bars? Wish I had lived in your street! I usually only get the little minis because I don’t want full-sized candy bars in my house! I love the look of these cookies, so festive and pretty.

  16. I’m so impressed that you hand out full-sized candy bars! I’d be one of those trick or treaters who changed my costume to come back to your front door and get another 🙂

  17. We love M & M cookies here but I’ve never made them chocolate before! If they see this I’ll have to start…that’s not a bad thing. BEAUTIFUL cookies, Liz!

  18. Oh a cookie/brownie…with candy. Sounds really good. yep I used to raid the chocolate bars beforehand too.

  19. These are sooo pretty, Liz. Very great tip about pressing in the candies when they emerge from the oven…Lucky you that you’ve got trick or treaters at your door. Holidays truly are so much more fun with young ones around =)

  20. I love brownie cookies, and the M&M’s are the perfect addition! So cute!

  21. Kids will be lined up around the block waiting to get to your house. I bet there were smiles all around when you made these.

  22. Mmm, brownie cookies and M&Ms? Is that perfect or perfect 😀


  23. Man, I love Halloween. Although I wasn’t allowed to go trick or treating (I was that pathetic kid giving candy out to the other kids) I’d always help myself to the candy my parents would buy for distribution. M&Ms are perfect for cookies, as demonstrated by yours, Liz. Do you still buy full sized candy bars to give out? No wonder your house is swamped on Halloween! You’re the neighbourhood hero 😉

  24. Your M&M cookies look gorgeous and when I saw them on FB (actually, think it was Google +) I thought these would make very good trick or treat goodies. Are you allowed to hand out hand-made treats? We are – just! It’s one thing they haven’t yet outlawed. You would think hand made treats would have to be better for kids than those made in factories xx

  25. Super festive cookies, loving how bright and cheerful they are!

  26. Brownies and M&M in a cookie? Sounds wonderfully delicious Liz. Love this combination here –YUM! 🙂

  27. They look super rich and delicious, Liz. I love the combo.

  29. Now this one would completely be a hit with my boys. Looks so good.

  30. Brownie cookies sound delish! The texture sounds so yummy with the m&ms. Too cute!

  31. Hello! These look amazing. Brownies cookies sound perfect!

  32. full-sized candy bars?! I would have loved trick or treating at your house!! I have so many fun memories of Halloween and sounds like you do too! I just love M&Ms in cookies! I agree, you have to save a few to press into the top…they look so festive!

  33. Such a classic cookie! I love these, Liz. They remind me of when I was a kid and loved rainbow everything. Well, actually, that hasn’t changed much!

  34. These look so delicious! I would much rather eat cookies than candy… especially yours 🙂

  35. these cookies look beautiful Lizzy!!

  41. I have some m&ms downstairs that would go beautifully in these. Perfect for my father-in-law to come home to.

  42. I wish there was a house like yours when I was growing up. I bet you get so many because the word is out with the full sized candy treats. I am expecting lots of kids this year in the house. I am so excited. I hope I don’t run out of candy!

  43. Lizzy,
    Brownie cookies are so good. I could gobble a few down right now.

  44. I love M&Ms in cookies and brownies, and I especially love how they look sprinkled on top! Great Chocolate Party recipe!
