When it is really cold out, or quite frankly, you are just hungry, oatmeal cookies are the perfect answer- you get a little bit of sugar for energy, you get a little bit of oatmeal for fibre, and the chocolate is just for fun! I took a monster cookie recipe with M&Ms and tweaked it a bit with chocolate chips, because I didn’t have M&Ms on hand and I had chocolate chips to use up- I also made a few small changes that I will note. These were a huge success with the family, and will absolutely be a re-do! Now to the cookies!

I found this recipe on Together As a Family- Jessica’s blog is a great place to find kid friendly recipes that are easy to make, usually make fairly large servings, and almost always nicely fit into that “Comfort Food” category that so many of us love!
The Best Monster Cookies
Ingredients
-1/2 cup butter, softened
-1 cup brown sugar
-1/2 cup creamy peanut butter
-1 large egg
-2 teaspoons vanilla extract
-3/4 cup all-purpose flour
-1 teaspoon baking soda
-1 teaspoon cornstarch
-1/4 teaspoon baking powder
-1/4 teaspoon salt
-1 1/2 cups quick oats
-1 cup mini semi-sweet chocolate chips
-1 cup mini M&M candies
Instructions
1. Preheat oven to 350 degrees. Line cookie sheets with parchment paper or use a silpat liner.
2. In a large bowl (or bowl of a stand mixer) cream together the butter, brown sugar, and peanut butter until light and fluffy, about 3-4 minutes.
3. Mix in the egg and vanilla, scraping down the sides of the bowl as needed.
4. In a separate bowl, add the flour, baking soda, cornstarch, baking powder, and salt and whisk to combine.
5. With the mixer on low speed, slowly add the flour mixture to the wet ingredients and mix until just combined.
6. Add the oats, chocolate chips, and M&M candies. Mix on low speed just until dough is combined.
7. Use a small/medium cookie scoop, or about 1-2 tablespoons cookie dough, and place on the baking sheets.
8. Bake the cookies for 7-9 minutes until the edges are just starting to brown and the top still looks slightly undercooked.
9. Remove from the oven and cool for 5 minutes on the baking sheet before moving them to a wire rack to cool completely.

Changes I Made
-I subbed chocolate chips for M&Ms because that was what I had on hand- I think it worked just as well! You could probably also sub out some of the chocolate for walnut pieces if you like nuts in your cookies.
– I reduced the peanut butter by a tablespoon. I am not a fan of peanut butter cookies, and I wanted to ensure that it wouldn’t be a hugely overwhelming peanut butter taste. It actually was still on strong-ish side, but not so much that I didn’t enjoy them.
-I baked 6-7 minutes, but realistically that could have been because of my oven!
♠
All in all, glowing reviews from the family, these are definitely a do-over! I ate one after finishing a run at the gym at lunch, and the small-ish cookie had enough punch to keep the hunger at bay until dinner, and keep me alert at work. (Also, have you ever had a cookie that was so bad that you regretted eating it? Probably not. It’s a cookie.)

Ooh sounds yummy! Although do you think you can cut out the peanut butter? (I’m allergic to nuts)
With added peanut butter? Yes please! Oat and raisin cookies are my all time favourites, from an American cookery book brought back for me by my now husband several years ago. You can’t beat North Americans for cookies!
I have to say, North American cooking isn’t the best or healthiest, but we do do cookies VERY well!! (It was one of the things I missed most when I lived in Dublin!)
These look great! Often you see one or the other, chocolate or oatmeal, I love the idea of joining the two!
I haven’t made cookies in forever, but I’ll have to try these out soon!
They look so good! Can’t go wrong with a chocolate chip cookie ?
I love chocolate cookies. And when it’s home baked…it’s even better! 🙂
Cookies with oats.. yummy ?
I love to bake when I am in a mood. This is unique recipe as I have never heard oatmeal chocolate chip cookies. Thanks for the recipe will try to make these soon☺☺
Yum, looks great Jess.
Oatmeal and chocolate chips is the best combination. I’ve been on the lookout for a good standby recipe so I’m looking forward to trying yours!
Loved the recipe…….hope to try it 🙂
Let me know how they turn out!! 🙂
I made some yesterday that actually went straight into the rubbish bin. The hubs embarked on a new eating plan a month ago. I keep trying out new recipes. This one was a heinous mistake. Tasted sooo bad. Of course my brain is already thinking of how to remake it and make it actually taste good. LOL
Oh, I have had sooooo many recipes that are just abandoned after one attempt because they can’t be saved. I find that trying to make desserts overly healthy doesn’t work lol- you can only substitute so many things!
Well the recipe called for an obscene amount of stevia. I quartered the recommended amount. And it still tasted like a chemical storm. Blech.
I’m not going to lie, I can’t stomach stevia. I find that if I really have to cut out white sugar, I will just have some fruit for dessert- I know that it’s still sugar, but at least it comes with nutrients! In fairness though, I don’t add sugar to anything but baking, so I don’t try any other sweeteners too often!
I used to use coconut sugar or maple syrup with baking but both of those are a no no on keto
These look so delicious! I’m not a massive fan of peanut butter either so I’d probably do what you did and just reduce it a little.

Someone else who doesn’t think I’m crazy for not loving peanut butter!! And when I was a kid, monster cookies never had peanut butter. I don’t know when that change happened but I am going to make monster cookies sans PB!!
