The holiday season means lots of fun desserts, and this recipe is one that you will want to make again and again! 

These Christmas cookie bars are very similar to my cake mix cookie bars, but made with red and green M&M’S in place of chocolate chips. 

Bake these for your family get togethers, or wrap them up as a thoughtful holiday gift!

First, beat the eggs in a mixing bowl, then add the cake mix and melted butter.

Beat well with mixers until combined. 

Add in 1 cup of the M&M’S and the white chocolate chips, and mix again until combined.

Grease a 9 X 13 baking dish with cooking spray, then spread the batter out evenly.

Every bite is filled with sweet white chocolate and m & m’s.

Store leftovers (if there are any!) in an airtight container or ziploc bag and enjoy within 2-3 days for best taste.

These are so good and so very simple to make, you just can’t go wrong!

I like to call them magic cookie bars, because they are so easy but really impressive for parties or gifts.
