These Reese’s Pieces cookies with chocolate chips and oatmeal are almost too easy to whip up. They’re bursting with peanut butter and chocolate flavour. All you need is a tall, cold glass of milk for dunking!

I’m in a funny mood today (pretty much 99% of the time, actually). I made these Reese’s cookies out of necessity.
Necessity?
Yes, it was necessary.
You see, I do the same thing every year.
I buy the dang Halloween candy bars, like, in September and absolutely devour the box the first weekend it’s in the house. Every year it’s the same. I think to myself that I’m not going to eat the candy.
What do I do?
Eat all the candy. Okay, not all, but a good chunk of it.
After hiding my shame or, um, throwing away the candy wrappers the next day, I decided to make cookies (because what better than a night of stuffing my pie hole with candy than making a batch of candy and chocolate-filled cookies, LOL).
Least there will be some candy left for the kids. Okay, I really have to buy more, but whatever.
In the event that you do have leftover Halloween candy, these Reese’s Pieces cookies would be a great way to use it up!

Those candy are like little bites of heaven!

Oh, and chocolate ain’t so bad either. Then there’s oats, which add a lovely texture and flavour to the cookies.

This Reese’s cookies come together in less than 10 minutes and there’s only about 14 minutes bake time.
That’s less than 25 minutes to peanut buttery, chocolate-loaded homemade cookies.
Dare I say better than candy bars?

You want a generous scoopful of batter for each cookie, place on a parchment paper-lined cookie sheet and bake.

I could tell you in further detail what makes these cookies delicious, like:
- the buttery texture
- creamy milk chocolate chips
- super peanut buttery Reese’s candy
But you should just make them for yourself!

More Easy Peanut Butter Treats

Final (silly) thoughts … the way I look at it, is that candy and cookies help keep me fit. Without them, would I work out? I think not! So, it’s necessary that I make these cookies. Good argument, huh? Oh, the little lies we tell ourselves, LOL.

Reese’s Pieces Cookies

- Meanwhile, in a large bowl, whisk together the flour, oats, baking powder and salt. Set aside.
- In the bowl of a stand mixer fitted with a paddle attachment (or in a bowl with a hand mixer), blend butter with brown sugar and granulated sugar until smooth and fluffy, about 2 minutes (stop as necessary to scrape the sides of the bowl with a rubber spatula).
- Add vanilla extract and blend to combine, about 30 seconds.
- Add eggs, one at a time, and blend until combined, about 1 minute.
- Pour reserved flour mixture into butter mixture and blend until combined, about 1 to 2 minutes. Add candy and chocolate chips and blend about 1 minute.
- To make cookies, place about 1 tablespoon scoopfuls of cookie dough, about 2 inches apart (you may have to to two batches, depending on the size of your cookie sheet) onto prepared cookie sheet.

Kathy @ Beyond the Chicken Coop says
Oh dear…you do have a problem! 🙂 Of course, I do the same with coconut, Almond Joy candy bars. It’s a bit of an addiction! I like how you used your obsession by making them into cookies! YES!!! This is another brilliant excuse for eating more candy!
Girl Heart Food says
Haha – right 😀 ?! Oh, those are delish too! Thanks Kathy!
Valentina says
Your cookies lured me in. YUM! I’m with you on the Halloween candy and do the same thing. In fact, I’m even guilty of going in my kids’ bags of treats and “sneaking” a few. (Shhhh!) Seriously, these sound and look delicious! 🙂
Girl Heart Food says
Lol! I completely understand 😉 Thank you so much, Valentina. Happy to hear I’m not the only one that gets into the candy early 🙂
georgie says
yassss great idea!!!! I don’t think i’ve ever seen mini reeses though! ha ha i’m pretty sure i live under a rock sometimes!
Girl Heart Food says
Thank you Georgie!! They taste just as yummy as the regular ones…can’t go wrong either way 😉
Marissa says
What a super fun way to use up Halloween candy, Dawn! So far I’ve been able to leave the bag of candy unopened (from Costco so it’s HUGE). It’s all over if I open it early, lol!
Girl Heart Food says
Thank you Marissa!! Haha…I know, right? No going back then, lol.
Laura says
Dawn – I love your logic about working out – I think I use the same philosophy. Whatever works, right? These cookies look dang good! I’d take them over any candy bar, any day of the year! Thanks for the recipe! Pinning!
Girl Heart Food says
Hehehe….good one, isn’t it?? I think so! Thanks so much, Laura! Happy Monday to ya.
Kevin says
Who has any left over Halloween candy?! Its usually eaten before the day even comes, but this is a great way to use up what is left! Will be giving this a try!
Girl Heart Food says
Lol – so true 😉 Thanks Kevin! Hope you love ’em.
Milena says
My boy’s name is Reese and these are so happening next week! I am pretty sure he can handle the recipe himself:) Fun!
Girl Heart Food says
It’s meant to be! Thanks Milena! Hope you guys love them.
Kelly | Foodtasia says
OMG I do the same thing every year! I cannot be trusted around candy bars! I even hide them out of sight and then go raid the hiding spot! If they were full size bars I might resist them better. But these little bite sized bars – they seem so harmless. Just a bite, right? Then whole bags are gone!
Love, love, love these cookies! Oatmeal gives such a yummy chew. I just want to bite into one of those crispy edges!
Girl Heart Food says
Right?! So difficult!! And, after all, they are only a small bite like ya said 😉 Thanks so much, Kelly!
annie@ciaochowbambina says
“Me want cookie!!” ~Cookie Monster….and I have that I common! 😉 I love how puffy and delightful these are! Wouldn’t mind sitting down to a big plate of these and a nice cold glass of milk! YUM!! Have a great week, my friend! XOXO
Girl Heart Food says
Hahaha….good one!!! Same here! Sounds like the best kinda plan 😉 Have a great week too, lovely. XOXO
Jennifer @ Seasons and Suppers says
Lol! You are not alone 🙂 Living in the bush as we do, we don’t even have kids who dare to walk up our spooky, dark lane, so we have NO Halloween visitors. And we still buy Halloween candy 😉 This is such a great way to use some of it! They look delicious!
Girl Heart Food says
Hahaha – love it!! Just in case, right 😉 ?? Thanks Jennifer!
Mary Ann | The Beach House Kitchen says
Lol! I do the same thing Dawn! I bet most people do. I’d have a hard time not gobbling up each and every last one of these too. Delicious combo! On my baking list!
Girl Heart Food says
I sure hope so!! Thanks so much Mary Ann 🙂
Kelsie | the itsy-bitsy kitchen says
GIRL! Your intro is the story of my life. This year I made the executive decision not to buy Halloween candy because I have mini candy bars leftover from recipes and I figured I’d just give those away. . .and, even though I avoided eating them all September, now that October is here I keep sneaking a couple a day. It must be something about the time of year that makes us need candy! Or that’s what I’m telling myself. . .Anyway, these cookies look PERFECT! I love oatmeal cookies and the texture on yours looks out of this world!
Girl Heart Food says
Hahaha! So happy I’m not the only one who gets into the candy early! Oh my! Maybe if we buy flavours that isn’t our fave? Maybe we wouldn’t get into it? Doubtful, lol 😉 Thanks so much, Kelsie!
David @ Spiced says
I do the same thing with Halloween candy around here, too, Dawn! I get it early in the month “to get ready for Halloween.” Then I have to go back and buy more later in the month for actual Halloween. Haha! So I must say that oats in cookies is one of my favorite things ever! I know you added them for a “healthy” twist, but that’s what caught my eye first. Well, to be fair, the Reese’s caught my eye about .2 seconds later. Haha! These cookies sound awesome, and I might just need to make a batch here. Yum!
Girl Heart Food says
Haha – glad to hear I’m not the only one 😉 I definitely think a batch is in order! Hope you love ’em, David!
Leanne | Crumb Top Baking says
I love baking with reeses pieces! I usually add them as a topping to magic cookie bars, but adding them to oatmeal chocolate chip cookies sounds equally as delicious! And I appreciate the little lie you tell yourself! Sounds like solid logic to me! 😉 Hope your week is off to a great start Dawn!
Girl Heart Food says
Haha – thanks girl! Have a great week too 🙂
Bill says
I’m reading this on a Sunday morning and I can’t believe I want cookies now instead of breakfast. It must be the oats. Sure, that’s it. (Leftover Halloween candy is a new concept for me.) I can smell them baking now :).
Girl Heart Food says
Haha – I think these would be perfectly acceptable for a weekend’s breakfast 😉 Thanks so much, Bill! Hope you’re week is off to a great start!
