M&M Blondies Recipe
Happy Monday! How was your weekend? How was your Easter? We indulged in an extra lazy few days that included carrot cake for breakfast, an epic parks and rec marathon, and way too many mimosas! I’m definitely in need of a green juice/green toast detox day… but first, just one more bite of these brown butter M&M blondies đ
These blondies are wildly delicious and super simple! To make them you will need butter, sugar, eggs and egg yolks, flour, salt,  and M&M’s. M&M baking bits or M&M’s will work just fine! And I like to throw in some chocolate chips, too! But this is totally optional! The most complicated ingredient is probably the brown butter… but don’t skip it! Because it gives these blondies epic flavor! And I’ve got all of the details on how to make brown butter below!
How to Brown Butter
Brown butter is so delicious and easily made right on your stove top. All you need is a stick of butter, a pan, and some patience. The transformation from melted butter to browned butter is made by toasting the milk solids in butter so that the liquid turns a deep, rich, nutty brown. It adds a delicate, nutty taste to the blondie batter that really elevates the flavor in these blondies to a whole new level of delicious.
To make the brown butter youâll simply take a stick of unsalted butter and place it into a cold saucepan. Youâll melt the butter over medium-heat, stirring it periodically to make sure that the butter does not burn. The simmering butter will begin to foam slightly, and eventually it will begin to turn a nutty brown color. When it has browned evenly, simply remove it from heat. Be sure to stay especially attentive at the end of the browning process to avoid burning the butter.
Time to Bake
Once your batter is assembled, you’ll want to scrape it into a 9×13-inch baking pan and press it evenly into the pan. The batter is very thick, so the easiest way to do this is place a piece of Saran Wrap on top of the blondie batter and press it with your hands. Then pop it into the oven for about 30 minutes! I usually pull mine out at 24 minutes… but a lot of people like theirs more “well done”, so if that’s you, bake a few extra minutes. But remember, the blondies will continue to cook and firm up even after you take them out of the oven!
Thick and chewy M&M blondies are so easy and delicious! No wonder they’re always a crowd-pleaser. This is a great recipe for birthday parties, picnics, and potlucks! Enjoy!

Thank you, Kayle! Brown butter makes everything better, ya know? đ
These are worth the drive bay to the grocery store for sure! Thanks!
Haha! I totally agree đ I’d love to hear how they turn out!
But blondies are made with white chocolate right?!
Made these this week and they were wonderful, especially if you’re the kind of person who likes a chewy cookie. So easy for a baking novice like me.
So happy these were a hit, Sar! Thank you for letting me know đ
Do you use salted or unsalted butter? Thank you
Use salted butter if you don’t plan on adding salt but add salt if you use unsalted
Loved these! Especially with butter browned in an iron skillet, added a dash of almond extract and sprinkled dark chocolate m&m’s on top before baking – amazing!!
I just made these for the first time and oh. my. goodness. Probably one of the best things iâve ever baked and also one of the easiest! The brown butter really makes a difference đ
Yay! I’m so happy you loved them as much as we do!!! And you’re so right: brown butter makes SUCH a difference đ
I made these tonight for my husband for Valentine’s Day. I don’t even like blondies but these were amazing. He LOVED them. It’s all about that brown butter. Thank you for sharing g this recipe.
HiAshley,
This recipe looks great; just one question. Are you using regular M & M’s (sold on any store), or are you using baking M & M’s?
Thanks
Brown butter! Seems like a hard task but it was actually rather easy…and delicious. Makes me wanna do the same to other baked goods. Turned out so well. They were a hit.
Have you ever tried to double this recipe for a 13×9 pan?
Is it not too sweet?
I was excited to bake these but they turned out way too buttery. Thinking they need some more flour to balance out all of the melted butter. For me, they turned out greasy which was disappointing.
Hi, I just pinned this recipe the other day so I could bake it in his weekend and I swear the original recipe was for an 8×8 pan and didnât call for chocolate chips just M&M. Am I losing my mind or did you update your recipe?
After looking at several recipes I made this one today, the brown butter is definitely a game changer. Only things I altered was I did add 1/2 teaspoon baking soda and only did one cup mini m&mâs. Baked mine for 28 minutes and they are perfect. Whole family loves them. Definitely saving this recipe.
