Monster Cookies

Monster cookies were my kids favorites at one time. Now I'm making them for the grands and sometimes I even have a little helper in the kitchen. They are a large peanut butter oatmeal cookie and are safe for those on a gluten-free diet if you use gluten-free oats.

  • 1/2 cup butter
  • 1 1/4 cup brown sugar
  • 1 cup white sugar
  • 3 eggs
  • 1 teaspoon vanilla
  • 1 1/2 cups peanut butter
  • 2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 4 1/2 cups oatmeal
  • 1 cup chocolate chips
  • 1 cup M & M's *
  1. Cream butter with sugars.
  2. Beat in eggs and vanilla.
  3. Add peanut butter and mix until combined.
  4. Stir in remaining ingredients.
  5. Drop by rounded tablespoon onto greased cookie sheets...or lined with parchment paper.
  6. Bake at 350°F for 10 not overbake.
  7. Wait for several minutes before removing from pans.
*I prefer the baking M & M's, but the larger ones work as well.

Be sure to recruit a little cookie monster to help with the entire process!


  1. Yummy.I know I would have a 4 year old helper ready at a moments notice.

  2. These are very good cookies. I have a PB allergy in my home so I don't make them. Yesterday I made a PB-free version so that our son could enjoy a cookie too!

  3. Your little cookie monster is such a great model .. even showing how yummy grammy's cookies are. Help in the kitchen certainly takes the dullness out of making a recipe for the 100th time.

  4. Ohh ! guess what I'm off to do ??
    Make monster cookies! I MIGHT share them with my grands... SMILE
    Thank you for the recipe, Judy !

  5. Well, now I have been waiting for this recipe...makes my Tuesday afternoon activity more interesting.
    I love watching R put those on the pans...and better yet, eating them

  6. This ones a keeper! Thanks for sharing.

  7. My Grandma had a recipe for Monster Cookies, but it was huge! (12 eggs, 4 cups white sugar, 18 cups oatmeal....etc). I think she had enough for 6 grandkids for the whole weekend when she made them! They were some of our favorite cookies though. I'm glad there is a smaller recipe available. When I get a chance to make monster cookies again, I'll have to try yours. Thanks!

  8. These cookies are a favorite around here too. Your little helper looks like a pro in the kitchen:)

  9. Judy, these pics bring back great memories of my time with Natalie recently. The recipe is almost identical. I'm glad you posted it. We used less sugar bec of altitude and I will be doing the same now too.

  10. These look wonderful. I'll defintely be trying them! My Husband is sure to love them. I'm a long time reader of your fabulous blog, but first time follower as I've only just opened a blogger account and set up a blog ( I just hope mine is as great as yours! :)

  11. Yummy! You have a sweet relationship with your little grandson....I'm sure he will be glad to pose for treats. Kathy

  12. Mmmmm!!! Thanks for this two year old son and I enjoyed baking them on a rainy, windy afternoon after successfully planting our garden in the morning. (And I must say, the baby I am "baking" enjoyed them too.) :)

  13. I just pulled out my first batch - if they taste as good as the dough - I am in trouble! Delish :)
    I doubled the batch (taking dinner to a friend with a new baby)and it made waay too much for my Kitchenaid to handle. Next time I'll go with a single batch.
    Thank you for all of your amazing help in the kitchen!

  14. Made these cookies this week. They are so yummy and have become a family favourite all ready!. Thanks so much for sharing your recipe,

  15. Made these cookies for a camping trip! My recipe is the huge one. They were the 'go-to' snack of the weekend! Good thing the recipe was soooo big!

  16. If the rest of my family was around I dont think they would even make it out of the oven! Thanks for this great recipe!

    Using them for a Type of cookie eating contest on my bus ride home from school with some friends..hope they turn out!! But knowing us we won't care if they do or not!

  18. I made these for the first time tonight, and they were absolutely delicious. I was worried because they don't call for flour, but the oats were just the ticket. My husband, who tries to avoid cookies, ate four in a row. Instead of chocolate M&Ms, I included peanut butter M&Ms, which added an extra pop of peanut butter taste. Thank you for posting this recipe.
