How to make m&m’s cookie bars
Step 1: Add the eggs to a mixing bowl and whisk them up.
Step 2: Add the white cake mix and melted butter. Beat the ingredients well with mixers until the batter is combined.
Step 3: Add 1 cup of the Christmas colored M&M’S and the white chocolate chips to the batter, and mix again until combined. This is easiest to do with a rubber spatula by hand as the batter will be quite thick.
Step 4: Grease a 9 X 13 baking dish with cooking spray, then spread the Christmas cookie bar batter out evenly. This is easiest to do using greased hands or a rubber spatula.
Step 6: Top the cookie bar batter with additional red and green M&M’S, then bake at 350 degrees until lightly golden brown.
Once the Christmas cookie bars are done, remove them from the oven and allow to cool before cutting.
Slice into pieces and watch them disappear!
Can I use another flavor of cake mix?
Yes! These would be yummy with yellow cake mix, vanilla cake mix, and chocolate cake mix too. Follow the same instructions as you would with the white cake mix.
Every bite is filled with sweet white chocolate and m & m’s.

Store leftovers (if there are any!) in an airtight container at room temperature and enjoy within 2-3 days for best taste and freshness.
