How to Make M&M Cookie Bars:
1. Combine dry ingredients: flour, baking powder, baking soda and salt in a medium bowl; set aside.
2. Combine wet ingredients: Add butter, sugar and brown sugar to a large mixing bowl or stand mixer and beat well until creamed together. Add egg and vanilla and mix until combined. Gradually mix in the dry ingredients and mix until combined.
3. Add chocolate: Stir in chocolate chips and m&m’s.
4. Bake: Press dough into a greased 9×13” pan and bake at 350 degrees F. for 18-25 minutes. Remove from pan and let cool completely. Pull up on the sides of parchment paper to remove bars from the pan and cut into squares.
Make Ahead And Freezing Instructions:
To make ahead: The cookie dough can be made 2-3 days ahead of time, stored in the refrigerator.
To freeze: allow baked bars to cool completely after cooking and cut them into squares. Place squares into a freezer safe bag or container and freeze for up to 3 months. Cookie dough can also be frozen for up to 3 months.
Recipes Variations:
- Add nuts: chopped walnuts or pecans
- Substitute the chips: feel free to add or substitute your favorite “chips”, like peanut butter or white chocolate chips.

I originally shared this recipe June 2017. Updated October 2020.
I made these to bring to a kids party and everyone raved! Thanks so much for sharing this recipe.
We tried them too, my kids stirred in some peanut butter and they were awesome!
Hello, sorry i am from Germany, we bake with gram or pound. Can you tell me please how much butter are 12 Tbsp in gram?
Thank you ?
Michi
I believe 12 Tablespoons of butter would be about 172.5 grams. Enjoy!
These look similar to a cookie recipe I use…so yummy! I’d like to double the recipe and bake in a large cookie sheet with sides…would you bake at same temp and maybe increase time to 20 minutes? Thanks!
I don’t think you need to do either. Just use same temperature and keep an eye on them if they may need a minute or two more but not sure they will.
Easy, easy recipe! I made these during the pandemic shut down and they went so fast. They are delicious! I am making them again for the 4th of July with red, white and blue M&Ms. can’t wait!
They were delicious and quite a crowd pleaser. I would definitely recommend this recipe and will make them again!
These are so delicious! My go-to blonde brownie recipe from now on!
I added 1/4 c. cocoa to the mix and some pearl sugar on top for extra crunch! These are the perfect consistency and yumminess. Thanks!
