Triple Peanut Butter Cookie Pie — This fast and easy cookie pie has peanut butter worked in three different ways. If you’re a peanut butter lover, this pie is for you!
Easy Peanut Butter Cookie Pie
This is the fastest and easiest pie I’ve ever made. And the only one with peanut butter incorporated three ways.
Except it’s not really a pie at all. I used my recipe for peanut butter blondies and baked it into pie dish, but not before topping with mini peanut butter cups and Peanut Butter M&M’s. It’s my annual contribution to National Peanut Butter Day, which was January 24.
The pie turned out to be one of my favorite blondies recipes ever. According to my Wordpress tags, I’ve tagged 29 recipes as blondies. Okay then, I’ve made more than a couple versions, but the base always starts out the same.
One stick of melted butter, 1 egg, 1 cup brown sugar, 1 tablespoon vanilla, with 1 cup flour stirred in. Truly a 5-minute batter. No-mixer, nothing complicated, or fussy. The opposite of what making a real pie tends to be.
The interior is squishy soft and supremely moist, while the edges are chewier with a slight crispiness. There’s no baking powder or baking soda in my blondies because I like them really dense and not at all cakey.
The peanut butter flavor is bold and pronounced, something you’d expect with as much peanut butter as there is packed into this pie.
The brightly colored M&M’s draw me in initially, but it’s the baked-in peanut butter cups that steal the show. I can’t resist peanut butter cups and they add texture to the buttery soft dough, as well as just enough chocolate to satisfy my chocolate + peanut butter cravings.
The pie would make a great base to top with ice cream or even as a fun ‘birthday cake’ for kids, and so much easier than cake since you don’t have to cream any ingredients or frost it.
Over the years of blogging and writing a cookbook devoted to peanut butter, I’ve combined peanut butter, chocolate, and candy in almost every imaginable combination and permutation, but never as a cookie pie.
Glad I can check that off my list now.
What’s in Peanut Butter Cookie Pie?
To make this peanut butter cup cookie pie, you’ll need:
- Unsalted butter
- Egg
- Light brown sugar
- Vanilla extract
- Creamy peanut butter
- All-purpose flour
- Salt
- Mini peanut butter cups
- Peanut butter M&M’s
How to Make a Giant Cookie Pie
This cookie cake pie comes together much like a regular batch of cookies would! Whisk together the melted butter, egg, brown sugar, peanut butter, and vanilla.
Add the dry ingredients and stir until just combined.
Turn the cookie dough into a greased pie plate, then insert the peanut butter cups into the batter, pushing them down so the top is almost flush with the surface of the dough. Insert the M&M’s next.
Then, it’s just a matter of baking the cookie cake pie until done!
Can I Use Natural Peanut Butter?
No, natural and homemade peanut butters are often too runny and too oily for baked goods. I recommend using a ‘classic’ peanut butter brand like Jif or Skippy.
Can I Use Chunky Peanut Butter?
I personally prefer the consistency of creamy peanut butter in my baked goods, but you’re welcome to use chunky peanut butter if desired.
How to Store Peanut Butter Cookie Pie
This cookie cake pie will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months. Note that the color may leech from the M&M’s if you freeze it.
How to Reheat Cookie Pie
If you want to reheat leftover cookie pie to make it nice and gooey again, I recommend gently heating the portion you’re going to consume in the microwave in 10-second intervals. Don’t reheat portions you’re not going to consume because then it will get hard.
However, this peanut butter cookie pie is so soft naturally, we enjoy it at room temperature.
Tips for Making Peanut Butter Cookie Pie
If you don’t have peanut butter cups or Peanut M&M’s on hand, use what you do have. Chopped Twix, Snickers, Rolos, plain M&Ms, it’s all good.
Use the recipe as an excuse to clean out your pantry of random candy and half-opened bags of baking chips. If you wait until after Valentine’s to make it, you can clean out all those Valentine’s exchange candy remnants. You’ll have your pantry widdled down just in time for the Easter Bunny, who brings more candy.
For optimal results, cool this cookie pie overnight because it gives the flavors a chance to marry and the pie to really set up fully.

Triple Peanut Butter Cookie Pie
Ingredients
- ½ cup unsalted butter, 1 stick, melted
- 1 large egg
- 1 cup light brown sugar, packed
- 1 tablespoon vanilla extract
- heaping 1/3 cup creamy peanut butter
- 1 cup all-purpose flour
- pinch salt, optional and to taste
- 12 to 14 mini peanut butter cups
- about 2/3 cup Peanut Butter M&Ms, I used one 2.83-ounce ‘King Size’ bag sold; optionally substitute with Peanut or Plain M&Ms
Instructions
- Preheat oven to 350F. Spray a 9-inch pie dish with floured cooking spray; set aside.
- In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
- Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, peanut butter, vanilla, and whisk until smooth.
- Add the flour, optional salt, and stir until just combined; don’t overmix.
- Turn batter out into prepared pie dish, smoothing the top lightly with a spatula.
- Evenly insert the peanut butter cups into the batter, pushing them down so the top is almost flush with the surface of the dough.
- Evenly insert the M&Ms into the batter, pushing them down to anchor.
- Bake for about 28 to 30 minutes, or until a toothpick inserted in the center comes out mostly clean, or with a few moist crumbs, but no batter. If your pie has risen in the center, it will deflate as it cools.
- Allow pie to cool in pan for at least 30 minutes before slicing and serving; however, for optimal results, cool overnight because it gives the flavors a chance to marry and the pie to really set up fully.

We made this tonight – used Reese’s pieces instead of peanut butter m&m’s. It is very good but extremely sweet. The texture is so soft and delicious.

My hubby is gluten free so I substituted the flour for Bob’s Red Mill 1:1 GF flour. It turned out amazing!!!! This is my new new go-to for my hubbys birthday “cake”. ( we aren’t big cake people, so we always try to come up with different things for each others birthdays).
Thanks for the five star review and glad Bob’s 1:1 worked great for you!

Today I made this with the kids who I watch. This was a great last week of summer treat for them. It was easy for them to help with all of the ingredients and stirring. We used whatever candy they had acquired and left over from other projects in addition to peanut butter cups! The only difference was that we halved the amount of sugar due to all the extra chocolate candy that got placed into the awesome peanut butter base at the end. :) This recipe was definitely delicious, fun, and very kid-friendly!
Thanks for trying the recipe and I’m glad it came out great for you! It’s a great candy cleanout recipe and sounds like you were able to make use of what you had on hand!
This is my new favorite go-to “pie” recipe. I’ll probably make it for every holiday from here on. I accidentally used a full cup of peanut butter once, and found I actually preferred it that way. If you love a peanut buttery taste, I recommend trying it. It gave it a smoother texture, too.
I can see where a full cup would be wonderful :) Glad you’re loving the pie and are a true PB fan like me!!
you’re the best baker i know. ive never been so impressed by someone in my life! seriously its just amazing what you create
You are just tooooooo sweet, Kelsey! Thank you for the kind words and for the YEARS of support. You’re the best! xoxo
I made this pie 4 times over the holidays – once for Christmas Eve, once for New Year’s Day, and twice more as gifts for a friend and godmother. The reviews from all are that it is extremely delicious! I must say that I am not the biggest fan of peanut butter, but this recipe changes all that. It is so moist and tasty, and I can’t wait to start baking all of the other recipes from averie cooks. So glad I found you!!!!
I love that you’ve made this FOUR times in pretty short order…but didn’t think you were much of a PB fan…glad my recipe converted you! I wrote an entire cookbook on PB in case you want to be tempted a bit more :) https://www.amazon.com/gp/product/1620876213/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=1620876213&linkCode=as2&tag=lovvegyogruna-20
Hi- I am hoping to make this for a holiday bazaar fundraiser. Can I use a throw-away pie dish instead of a glass pie dish? Many thanks –
You definitely can do it in a disposable. Sometimes they run a little skimpy so buy at least a 9-inch! You’re so nice to make this as a fundraiser!
Great – thanks for your quick response! Going shopping tomorrow!
Wow! The peanut butter chocolate chunk cookies were a big hit in my family! i brought them over for thanks giving. Everyone wanted seconds!
Thanks for saying that and so glad everyone loved them!
Oh my gosh. This was delicious! !! So happy I gave it a try! Posted a pic to my FB wall and got more ‘likes’ and comments than you could shake a stick at!! (Posted a link to your blog too, for all my baker pals)
Thanks for trying it and glad that everyone is loving it – this is one of my most popular recipes! People seem to love this – both the pics and the taste and ease of the pie! Glad you’re a fan too :)
Since I’m a chocoholic I’m not usually a fan of blondies but the peanut butter won me over. I bought a dollar bag of reese’s cups and a theatre box of reese’s pieces at the dollar store (there is NEVER leftover chocolate in our house lol) and only needed 1/2 to half the box. I was going to try to post a pic because I did mine all symmetrical :)
Thanks for trying the recipe and sounds like your pie was a winner!
I’ve now made this 5 times in the past 2 months. 3 times for treats at work, people literally fight over the last bite! And I love it because it’s one of the easiest things I’ve ever made! I figure I’ll have the recipe memorized before long!
5 times in 2 months…that’s awesome! And so glad to hear people literally fight over the last bite and that it’s easy for you to whip up – love hearing things like this!
