Thick and Chewy M&M Cookie Bars

by megan on January 16, 2013


If you’ve been reading for any length of time, you are probably aware of my love for cookies and bars that are thick and chewy. These thick and chewy M&M cookie bars just might be absolute perfection in bar form. :)  They are nice and soft, and of course there are lots of M&M’s sprinkled throughout! I love that half the M&M’s are mixed into the batter, and half are pressed into the top to make sure these bars turn out nice and pretty. I made these for some friends who stayed with us last weekend, and they were gone by the end of the weekend. These M&M cookie bars are definitely a treat you can’t turn down!

Thick and Chewy M&M Cookie Bars

*Note: I baked mine in a 9×9 pan because it was what I had available. However, I do think a 9×13 pan works better.  If you use a 9×13 pan (as written), yours will not be quite as thick.

Thick and Chewy M&M Cookie Bars

Yield: 1 9x13 pan

Prep Time: 15 min

Cook Time: 30 min

Total Time: 45 min

These cookies are soft, chewy, and chock full of M&M's!

Ingredients:

2 1/8 cups flour
1/2 tsp salt
1/2 tsp baking soda
12 Tbsp butter (1 1/2 sticks), melted and cooled slightly
1 cup brown sugar
1/2 cup white sugar
1 large egg
1 large egg yolk
2 tsps vanilla extract
1 12oz bag M&M's, divided

Directions:

Preheat the oven to 325 degrees. Adjust the oven rack to lower-middle position. Grease a 9x13 pan and set aside.

In a medium sized bowl, whisk together the flour, salt, and baking soda and set aside.

In a large bowl, whisk the melted butter and sugars until combined. Add the egg, egg yolk, and vanilla and mix well. Using a rubber spatula, fold the dry ingredients into the egg mixture until just combined; do not overmix. Fold in 1 cup of M&M's and turn the batter into the prepared pan, smoothing the top with the spatula. Sprinkle remaining M&M's on top and press in slightly.

Bake 25-30 minutes, until the top of the bars is light golden brown, slightly firm to the touch, and edges start pulling away from sides of pan. Cool completely before cutting.

    These look SOOOOO good! I love anything with M & M’s – they are so colorful and adults and kids seem to enjoy them equally. I like Erika’s idea too!

    P.S. Congrats on your adoption plans – can’t wait to hear more about it!

    Oh, my son adores M&Ms. I bet he’d love to whip up a batch of these with me. I’m thinking a weekend treat! Thanks for the inspiration!

    I love how perfectly chewy these look!
    I might try a browned butter version of these, because I’m sort of addicted to browned butter. :)

    I merely stumbled across your post and was compelled to bake these. Let the record state I’ve never baked anything from scratch in my life. Nonetheless, these turned out beautifully, and they taste incredible! If I don’t inhale the entire pan tonight, it will be a miracle. Thank you for sharing your creativity!

    amy @ fearless homemaker — March 21, 2013 @ 6:39 pm

    I made these yesterday and they turned out SO delicious. I’m so thankful I brought most to share with a group, because it would’ve been dangerous to have the whole pan in the house with me. =) I’ll be posting them on my blog either next Thursday or the following Tuesday if you want to check ‘em out!
