M&M Cookie Bars
M&M cookie bars are a wonderfully decadent dessert that you can make in less than an hour, including baking time!

The bars are perfect for gift-giving, in fact, after we tried a couple (of course) I took them to some friends to share–and they are always a welcome treat!
A Variety of Colors
The rich and chewy bars are a favorite around here and filled with colorful M&M candies. The cookie bars are perfect for any holiday and you can change the candy colors for each occasion.
You’ve seen the fabulous colors that M&M’s come in, including pink, red and green for Christmas, or you can even switch them out with peanut butter M&M’s for a different flavor. The possibilities are endless.

How To Make M&M Cookie Bars

Start by adding the flour to a medium-sized bowl.

Next, add the baking soda and salt to the bowl. Whisk the three ingredients together and set the bowl to the side.

In a large bowl, add the softened butter.
I am terrible about remembering to set the butter out to soften, so I usually put it in the microwave for a few seconds or use the “soften” mode.
If you don’t use either of those choices, you can just mix the butter with the hand mixer until it is creamy.

Next, add the granulated sugar to the bowl with the butter.

Add the brown sugar to the bowl.

The eggs and the vanilla extract are next. Mix the ingredients until creamy and well blended.

Pour the flour mixture into the bowl and mix well.

Pour 1-1/2 cups of the M&M candies into the bowl and mix well.

Finally, spread the cookie dough into a greased 9″ x 13″ dish. Top with the remainder of the candies.
Bake for 20-25 minutes or until a cake tester comes out clean. Let the cookie bars cool for at least 30 minutes.

The butter makes all the difference! I’ve tried other recipes and couldn’t figure out what was missing. THIS is the recipe to make. Lovely buttery taste.
Hi Wendy, Great to hear! Thanks for sharing. 🙂
“In a large bowl, add the softened butter and cream.”….there is no cream list’d in the ingrdts……….
Hi Sue,
I meant to cream, or mix the butter well, after you add it to the bowl. Sorry about that, I didn’t make that very clear! I’ll fix that.
