I absolutely love an oatmeal cookie, give me a brown butter craisin oatmeal cookie any day of the week! This cookie is really similar but made with regular butter and has peanut butter swirled in the cookie dough.
Tell me about this recipe!
- The oatmeal cookie dough is lightly spiced with cinnamon and nutmeg.
- Butter is creamed with light brown sugar and granulated sugar, giving you a soft and chewy cookie!
- I recommend chilling the cookies for 45 minutes beforehand as it is a sticky dough.
Ingredients Needed
The printable recipe card with the full list of ingredients and instructions can be found at the bottom of this post.
- Oats: make sure you are using whole, rolled oats - not quick cooking oats. Those oats will be too dry and powdery and your cookie won't have the same texture.
- Butter: I always use European style butter, like Kerry Gold, for my cookies! The higher butterfat content will make your cookies much richer.
- Peanut Butter: feel free to use smooth or crunchy peanut butter for this. You don't want to use peanut butter which has a layer of oil on top, that peanut butter may be too loose for this and the cookies will spread.
How to make this recipe
Step 1: In a small bowl, whisk your flour with your cinnamon, nutmeg, salt and baking soda. Set aside.
Step 2: In a stand mixer fitted with the paddle attachment, or using a hand mixer, cream your butter until it is very creamy.
Step 3: Add both of your sugars and your peanut butter and whip together for another two minutes. Make sure to scrape the side and bottom of the bowl so all the butter gets mixed in.
Step 4: Add in your eggs and vanilla extract, beating again for another minute.
Step 5: Pour in your flour mixture and mix on low until it is combined.
Step 6: Add in your oats and M&Ms and fold it all together. Chill in the fridge for at least 45 minutes. Preheat your oven to 350 degrees and line two cookie trays with parchment paper. Use a 3 tablespoon cookie scoop to scoop out the peanut butter oatmeal m&m cookie dough and place them 3-4 inches apart on the cookie tray. Bake for 13-14 minutes.
Recipe Tips
- I highly recommend using a weighing scale and measuring out your ingredients the metric way. It makes a huge difference to your baking and is the most accurate way to bake
- Want to make your peanut butter oatmeal m&m cookies perfectly round? Once your cookies are out of the oven, use a large circular cookie cutter and place it over the cookie. Scoot the cutter around gently, this will smooth out any edges and make your cookies perfectly round.
- Be sure to use whole rolled oats and not quick cooking oats. Using quick cooking oats will make your cookies too dry.
Frequently Asked Questions
Keep in a tupperware at room temperature for up to 5 days.
Once you've scooped out the cookie dough balls, place them in a freezer bag and freeze. When you're ready to bake, place in the oven and bake for an extra minute or two.
Swap out m&ms for chocolate chips, nuts, dried fruit, chopped pretzels - anything you like! I think it's fun to use chocolate candy in the colors for whatever holiday you're celebrating.

what if I use salted butter, should I omit the salt?
Ella says
I recommend maybe doing half the amount of salt or removing it completely! I haven't tested it with salted butter so can't say for sure.

OMG!!! I’ve been looking for years for a yummy oatmeal cookie! This is better than I could ever imagine! Chewy, soft and easy to make and scoop on to cookie sheet! I added raisins as I was about a half cup short on the M And M’s. I love monster cookies and this recipe is the best! I want to add coconut and sunflowers seeds and nuts next time! I also thought I wanted smaller cookies but one of these bigger size is perfect for me the Cookie Monster!! Thank you!
Ella says
Thanks so much for your review! I love the sound of adding coconut and sunflower seeds!
Jennifer says
Instructions say add eggs but I don’t see eggs on the ingredient list. How many should I use?
Ella says
You'll need 2 large eggs!
Kim says
We just made them. Flavor is excellent but the texture is very gritty. Followed the recipe with no changes or subs. Thoughts?
Ella says
Oh no, I'm sorry about that! What kind of oats did you use? The only time the texture wasn't right when I was testing these is when I used quick or instant oats.
Kimberly McGuire says
I made this in English metrics and no M&M just semi and milk chocolate and 10 packets of maple and brown sugar oat meal this equals 3 cups of oats !They turned out Great 👍 Thank you
