M&M Cookie Bars are an easy treat that the kids can help with! They can be dressed up for any season by buying a seasonal package of M&Ms. These was have green mint flavored M&M’s for St. Patrick’s Day!
These Cookie Bars are easy and fun to make for just about any holiday! Now they have M&M’s specially packaged for Valentines Day, St. Patty’s Day, Easter, Halloween, and Christmas, at the very least. There are probably a few others that I missed! You could just do them for a fun weekend project any time of the year with regular, multi-colored M&M’s!
What are cookie bars?
Cookie Bars is a general term in the world of cookies that refers to any cookie cooked in a large pan and then cut into “bars” or squares. Cookie Bars can be made in a endless variety of variations!
A Bit of History on the M&M’s
Sometimes the history of a specfic food, or it’s origins really fascinate me! For instance, M&M’s were first manufactured in 1941. The idea for the M&M’s occured during a trip to Europe when Forrest Mars observed British troops eating British Smarties, which were milk chocolate, coated in a hardened sugar coating, so that the chocolate did not melt.
M&M’s stood for the business partership between Forrest Mars and William Murrie, son of the Hershey’s chocolate president. The deal they struck allowed them to use Hershey’s chocolate, who had control of the rationed chocolate. (Chocolate was rationed during the war for the troops) The success of the chocolate is directly attributed to the second world war, when the United States Government was the companies’ biggest customer!
Can Cookie Bars be Frozen?
Yes. Cookie Bars can be wrapped in an airtight plastic wrap, or a container and frozen for several months.
How to make M&M cookie bars
- Line baking pan with parchment paper. Preheat oven to 350°F.
- Measure dry ingredients in bowl.
- Break 2 room temperature eggs.
- Two sticks of butter in mixing bowl.
- Cream until smooth and light colored.
- Add sugars and cream until light colored.
- Add eggs. Combine.
- Add vanilla. Combine.
- Mix dry ingredients in, in 3 additions, just until mixed.
- Add in chopped nuts by hand.
Spread out the dough evenly on the parchment paper. Add M&M’s to the top. Bake at 350°F for 20-25 minutes, until browned and tester inserted in the center comes out clean.
When to cut cookie bars
These M&M’s Cookie Bars should be cooled for 30- 1 hour, before cutting, depending on the air temperature. They should not be totaly cooled. They slice more uniform if the chocolate is just a bit gooey in the center still. Use a very sharp knife to cut through the M&M’s.
That’s how easy it is to make these M&M’s Cookie Bars! I hope you like the recipe today!
