Best M&M Cookie Bars

One of my favorite things about winter in Wisconsin is my ‘outdoor refrigerator,’ which is my deck. I bake a lot more in the winter than summer, so it’s nice to be able to cool things off quickly when I am in mass production for the holidays!

Like when I make a million Rolo Pretzel Turtles, Crock Pot Christmas Crack, Peppermint Pretzel Bites, and 2-Ingredient Peanut Butter Cup Cookies to give as Christmas gifts! It just takes a few minutes for the chocolate to harden as the pan sits outside!

I recently made these adorable Reindeer Oreos. As my husband was passing through the kitchen he offered to put them on the deck for me. As he was setting them outside he was talking to the reindeer treats as if they had just landed on the roof telling them not to fly away because they needed to go to school with our son! We got a good laugh out of it.

These Christmas M&M Cookie Bars are the perfect thing to make if you are racing against time!

What You’ll Need:

• 2 cups + 2 tbsp Flour
• 1/2 tsp Salt
• 1/2 tsp Baking Soda
• 3/4 cup Butter, Melted
• 1 cup Brown Sugar
• 1/2 cup Sugar
• 1 Egg

• 2 tsp Vanilla

How to Make Christmas M&M Cookie Bars

• Preheat oven to 325 degrees. Spray a 9 x 13 metal pan with non-stick spray and set aside.
• In a small bowl, whisk together 2 cups + 2 tbsp flour, 1/2 tsp salt, and 1/2 tsp baking soda together.
• In a separate medium bowl, beat together 3/4 cup melted butter, 1 cup brown sugar, and 1/2 cup sugar until well combined. Add in 1 egg, 1 egg yolk, and 2 tsp vanilla and mix.
