With Memorial Day approaching, it was time to bake up some festive, patriotic recipes to grace our picnic table. These irresistible Patriotic Monster Cookies are chewy peanut butter oatmeal cookies chock full of  red, white and blue M&M’s and chocolate chips.

Hot dogs and apple pie are classic Americana as far as foods go. Plus anything red, white and blue. I’ve made those desserts topped with blueberries and raspberries to look like an American flag,  s’mores desserts and grilled a slew of burgers and dogs. When the Sunday Supper crew decided to make patriotic foods for this coming Memorial Day, I remembered these festive, patriotic monster cookies dotted with red, white and blue.

My mom introduced my sisters and me to classic monster cookies in the ’70’s. Her recipe was huge, calling for 2 pounds of peanut butter and nuts in addition to the chocolate.

Extras were stored in our deep freeze and we were known to munch on them frozen. They were dubbed “monster” cookies due to their massive size–which our teenage metabolism could handle quite well.

This is a scaled down version–and one where you don’t have to calculate how many cups are in a pound of peanut butter! These cookies are super chewy and outrageously delicious. After you try this recipe, and fall in love with these cookies, I recommend baking up a batch of Monster Cookie Dough Cupcakes!

Tips for Making These Festive Monster Cookies:

  • Use a cookie disher to scoop out consistent size dough balls.
  • Roll between the palms of your hands to make dough balls more symmetrical (chilling the dough first makes this easier)
  • If your cookies come out of the oven misshapen, hold onto the cookie sheet using an oven mitt and with the other hand, use a spatula to reshape the hot cookies into rounds.
  • M&M’s tend to crack in the oven, so reserve what’s left in your bag to press into the hot, fresh out of the oven cookies for a more professional look.
  • Use other color combinations depending on the time of year to make festive monster cookies—red and green at Christmas, black and orange for Halloween.

Our Newest Family Member!


I “thought” I signed up for this week’s Sunday Supper, but I goofed. I could blame this on the newest addition to our family, Miss Isabelle, or Izzy. She’s now 8 weeks old, darling as can be, but full of mischief.

She was pulling out book marks from my cookbooks as well as chewing on them, so I removed all temptation from the bottom of the above bookshelf. She decided it was the perfect spot to perch. I’m sure Izzy will be making a few more appearances on the blog.

Note: This post was originally shared in 2015. Izzy is still a little rascal at 3 years old!

  7. Apart from being adorable these cookies sounds like a great sweet snacks!

  8. Great idea to combine peanut butter with the oatmeal. I might be tempted to go back to Mom’s way of doing them…as monster cookies but that’s because I know how much I am going to LOVE making these.

    Izzy is adorable and I have a feeling you may have to remove a couple shelves on that case as your baby girl gets bigger!

  9. These look so festive and fun. Thanks for the tip re the m & m pieces cracking in the oven, I didn’t know that. What is it with puppies and their love of pulling out bookmarks?? So cute and endearing when they do that, they feel so accomplished at having scored that bookmark! xo for Izzy.

  10. What a great idea for a cookie to bring to a potluck. I love seeing all the pictures of Izzy. She is so adorable.

  11. These are such festive cookies and Izzy is melting my heart! πŸ™‚

  12. These cookies look so pretty and festive, Liz! Love oatmeal and peanut butter together. And oh my goodness, Izzy is so so adorable! Hope you have a wonderful Memorial Day! πŸ™‚

  13. These are adorable and Izzy’s pictures always brighten my day on instagram.

  14. Peanut butter and oatmeal cookies are just the best. And what a great patriotic touch with the chocolates. Our puppy is now 9 months old, and it seems like yesterday that she was just 8 weeks old, taking over our household. Your puppy is adorable, and yes, you have lots of antics with her ahead of you. Love her little perch there.

  15. Gosh, Izzy is so cute! How could you ever get mad at a face like that? She’s gonna be a little bit of trouble, I can tell πŸ˜‰ Thank goodness you have a plethora of cookies! These look great – love monster cookies.

  16. What a lovely way to celebrate those who have sacrificed so much for us. Our memorial day is in November (Nov 11 to be exact) and it’s called Remembrance Day, celebrated by buying a poppy from a vet and pinning it to our jackets and coats. At the 11th hour of the 11th month of the 11th Day β€” literally everything stops for one full minute of silence and then they play a recording of In Flander’s Fields. It’s quite moving.
    Your cookies look wonderful, love the coloured smarties!
