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.

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.

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.

    “In a large bowl, add the softened butter and cream.”….there is no cream list’d in the ingrdts……….

    1. 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.
