Ingredients to make Christmas cookie bars

• melted butter
• eggs
• holiday colored M&M’S
• white chocolate chips

how to make m&m’s cookie bars

Step 1: Add the eggs to a mixing bowl.

Step 2: Beat the eggs with a whisk.

Step 3: Add the white cake mix and melted butter. Beat well with mixers until the batter is combined. 

Step 4: Add in 1 cup of the Christmas colored M&M’S and the white chocolate chips, and mix again until combined.

This is easiest to do with a rubber spatula by hand.

Step 5: Grease a 9 X 13 baking dish with cooking spray, then spread the batter out evenly. 

Step 6: Top the cookie bar batter with additional red and green M&M’S, then bake at 350 degrees until 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 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. 

If you have never made M&M’S cookie bars, this is your year!

Add another no fuss dessert to your holiday baking list that is a guaranteed crowd pleaser. 

Run to the store and grab yourself some cake mix and M&M’S and let me know what you think!

This recipe will be your go to for a fast and crowd pleasing dessert.

It’s safe to say these are going to be a favorite Christmas dessert for years to come.
