These cookie bars have red white and blue M&M's studded throughout for a patriotic M&M cookie recipe! Everyone loves these soft chewy American cookies!
Similar to my favorite chocolate chip M&M cookies, I make these festive M&M cookie bars quite often. It's easy to use different colors of M&M's to fit the theme of the occasion. Sometimes it's hard for me to find the red white and blue M&M's at regular grocery stores, even in peak patriotic season. But, I can typically count on the big tub of them at Sam's Club this time of year!

M&M Cookie Recipe
Because these are cookie bars, it is really easy to mix everything in just one bowl then press into a pan. Gather these ingredients:
Grocery List for M&M Cookie Bars
- Red, white and blue M&M's (2 ½ cups)
- All-purpose flour (3 cups)
- Unsalted butter (1 cup)
- Eggs (3 large)
- Brown sugar (1 ½ cups)
- Granulated sugar (½ cup)
- Vanilla (2 teaspoons)
- Baking powder
- Baking soda
Since this cookie dough is pressed into a sheet pan, it is very easy to change up the amount of sugar because you're not relying on the outcome of the shape of the cookie. If you like crispier cookies, use more granulated sugar and less brown sugar. Use less sugar all together if you like, and just two eggs. I like my cookie bars doughy and chewy, so this is the perfect combination for me.
How to make M&M Cookie Bars
- Preheat oven to 350°F. Grease rimmed baking sheet. (I use Baker's Joy.)
- In a mixing bowl, mix butter and sugars. Add vanilla and eggs.
- Stir in flour, baking powder, baking soda and salt.
- Fold in M&M's.
- Spread dough into baking sheet, sprinkle with more M&M's.
- Bake 20 to 30 minutes, until golden.

How to know when the cookie bars are done.
For this recipe, I typically use my 12x17-inch sheet pan. But, every home cook has a different sized sheet pan in their home. I do not recommend jelly roll pan size which is 15x10. It's too small -- barely! Because the rimmed edges are short it will ooze out and spill during baking. You can, however, use a 9x13-inch baking dish that has the higher edges.
I take my cookie bars out of the oven when they are lightly golden, but if you don't want them as doughy in the middle then you may want to bake longer until they are a darker golden exterior. If you are using a larger sheet pan, then less baking time may be required. The good thing is, these are hard to mess up so don't worry!

Red White and Blue M&M Cookie Bars
- 1 cup unsalted butter , room temperature
- 1 ½ cups light brown sugar
- ½ cup granulated sugar
- 2 teaspoons vanilla extract
- 3 large eggs
- 3 cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 2 ½ cups red, white and blue M&M's
- Preheat oven to 350°F. Grease large rimmed baking sheet (17x12-inch) with nonstick spray. (I use Baker's Joy.)
- In a large mixing bowl, cream together the butter and sugars until light and fluffy (about 1 minute). Beat in the vanilla and eggs. Stir in the flour, baking powder, baking soda and salt. Fold in 2 cups of the M&M's.
- Using a large rubber spatula, spread dough evenly into baking sheet. The dough may be thin if using a very large sheet pan, but will puff and close holes during baking. Sprinkle additional ½ cup of M&M's over top and lightly press into the dough.
- Bake for 20 to 30 minutes*, until baked to desired doneness and edges are golden. Do not over bake. Let cool.
- To serve, cut into squares with a plastic knife.
What size pan
Nikki Gladd says
Hi Charlotte, As the recipe states, I use a 12x17-inch sheet pan. You can also make them thicker in a 9x13 baking dish.
Can you freeze these cookies?
Nikki Gladd says
Hi Maddie, Yes, you can freeze these cookies. I would cut them into individual squares to freeze them.
I tried these not for me but you will probably like them, my sister loved them!
What size pan?
Nikki Gladd says
Within the blog post, you will see I stated I use my 10x15 rimmed baking sheet. But, you can use a little larger or smaller depending on what you have at home. Adjust baking time as necessary. If you do not own a rimmed baking sheet, I linked to a recommended one in the recipe card. 🙂
I'm glad I saw where you said 10x15 in the post because in the recipe it just says "large baking sheet". My 10x15 is what I consider to be medium and I rarely use it. I use my large ones all the time and they are 12x17. Only 2 inches bigger each direction, but it definitely makes a difference.
Nikki Gladd says
I've used my 12x17 and my 10x15 in this recipe, and my 9x13 pyrex! 🙂 It's true everyone has a different idea of what "large" means. That's why the baking time range is so wide (20 to 30 minutes) and I stated in the notes that the smaller the pan, the longer you need to bake. Thanks for the note!
