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 😉

These thick and chewy Brown Butter M&M Blondies are irresistible! An easy cookie bar that's loaded with chocolate chips and M&M candies. Loved by kids and adults, this blondie recipe is always a crowd pleaser! 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 you’ll simply take a stick of unsalted butter and place it into a cold saucepan. You’ll 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 Brown Butter M&M Blondies. Everyone loves these!

Ingredients

  • 1 cup (227 grams) unsalted butter, melted until browned
  • 1 and 1/2 cups (319 grams) light brown sugar, firmly packed 
  • 1/4 cup (50 grams) granulated sugar 
  • 1 Tablespoon vanilla extract 
  • 2 large egg plus 2 egg yolks, at room temperature
  • 2 cups (245 grams) all-purpose flour 
  • 1/4 teaspoon salt
  • 1 and 1/4 cups (210 grams) M&M candies 
  • 1/2 cup (85 grams) semi-sweet chocolate chips 
  • Flaky sea salt, for sprinkling, optional 

Instructions

  • Preheat oven to 350 degrees (F). Line an 9x13-inch baking pan with parchment paper. Set aside. 
  • In a saucepan over medium heat, melt butter. Continue cooking, swirling the pan occasionally, until browned. 
  • Remove from heat and cool for a few minutes, then scrape the butter into a large heat proof mixing bowl.
  • Whisk in both sugars and mix until well combined. Stir in the vanilla. Then add in the eggs and egg yolks, beating until combined. 
  • Using a rubber spatula, fold in the flour and salt, mixing until just combined. Finally, fold in the M&Ms and chocolate chips. Scrape the batter into the prepared pan. 
  • Bake for 26 to 30 minutes, or until the edges are firm and golden and the center is just slightly wobbly.
  • Cool in pan for at least 1 hour before cutting. Sprinkle with flaky sea salt before serving, if desired.

    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.

      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!!

    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

    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 didn’t 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&m’s. Baked mine for 28 minutes and they are perfect. Whole family loves them. Definitely saving this recipe.
