Cookie bars will always be one of my favorite desserts, especially these M&M cookie bars! The M&Ms are just my excuse to add more chocolate. ? Plus, making cookies without having to roll them into balls is a great shortcut!
These cookie bars are slightly crisp on the outside and extra gooey on the inside. They are loaded with chocolate, and the M&Ms add a nice crunch! I had a bag of red, white, and blue M&Ms for the 4th of July, so I used them to make this a festive treat!
How to Make M&M Cookie Bars
First, whisk together all of the dry ingredients: cake flour, salt, and baking soda. If you don’t have cake flour, use a combination of all purpose flour and cornstarch. Instead of using 2 3/4 cups of cake flour, use 2 1/2 cups of all purpose flour and 1/4 cup of cornstarch.
Next, cream the butter, granulated sugar, and brown sugar. Once creamy, mix in the vanilla extract and the eggs. Then, add in the whisked dry ingredients and mix on the lowest speed. After the dry ingredients are just barely incorporated, mix in the M&Ms and chocolate chips by hand with a rubber spatula. The dough should be pretty sticky, but don’t let that worry you!
Add the dough to a 9×13 pan lined with parchment paper. The parchment paper will make it easier to remove the cookie bars from the pan. Use a rubber spatula or knife to spread the dough evenly throughout the pan. Add extra chocolate chips and M&Ms on top as a decorative touch.
Bake the cookie bars at 350° Fahrenheit for 25-30 minutes, until golden on top. The cookie bars will still be really gooey, so let them sit until they reach room temperature before cutting them. (Or dig in immediately for an oversized pizookie! ?)
