Unbelievable Peanut Butter Pie

Peanut butter pie is rich and decadent, combining creamy peanut butter and sweet chocolate in each bite. This over the top dessert features a peanut butter Oreo cookie crust, peanut butter filling, Reese’s Pieces, and homemade chocolate ganache. It’s unbelievable!

There’s no flavor duo quite like peanut butter + chocolate. We’ve made chocolate peanut butter cheesecake bars, no-bake chocolate peanut butter bars, and chocolate peanut butter snack bars to name a few. My chocolate chip cookie layer cake is even filled with a chocolate peanut butter frosting! Today, we’re adding another recipe to the chocolate peanut butter mix: truly unbelievable peanut butter pie.

There’s a lot to cover, so let’s dive right in.

This Is Unbelievable Peanut Butter Pie

The layers! The textures! This might just be the richest dessert I’ve ever made. Today’s recipe is a new twist on classic peanut butter pie with a crunchy peanut butter Oreo cookie crust, colorful Reese’s Pieces candies, creamy peanut butter filling, and smooth chocolate ganache. It’s a peanut butter lover’s dream come true.

Here’s why you’ll love it:

  • Totally indulgent
  • Quick and easy to prepare
  • Made with only 10 ingredients
  • Tons of texture in each bite
  • Perfect for birthdays and celebrations
  • A great make-ahead recipe

4 Parts to Peanut Butter Pie

  1. Peanut Butter Oreo Crust
  2. Peanut Butter Filling
  3. Chocolate Ganache
  4. Reese’s Pieces

Though the written recipe is below, let me walk you through each part so you understand exactly what you’re doing.

Peanut Butter Oreo Crust

It wouldn’t be peanut butter pie without an Oreo crust, but let’s use peanut butter Oreos! Regular Oreos work just as well, but peanut butter Oreos add another layer of peanut butter flavor. Pulse the Oreos (the whole Oreo including the chocolate cookies and the filling) into a fine crumb, then combine the Oreo crumbs with a little melted butter. Just 2 ingredients, so easy.

Press the mixture firmly into a pie dish and bake the crust. I recommend beginning with this step so the crust has time to cool down before assembling. This is the only layer that requires baking– the rest of the recipe is completely no-bake! I love making this pie in the warmer summer months when our kitchens welcome a break from the hot oven.

Peanut Butter Pie Filling

This peanut butter filling is about as decadently rich as we can get. It’s made with just 5 ingredients including heavy cream, peanut butter, cream cheese, confectioners’ sugar, and vanilla extract. You can’t really taste the cream cheese; rather, you truly just taste peanut butter. It has as much peanut butter flavor as these peanut butter balls and my peanut butter cookies.

You’ll begin by whipping the heavy cream into whipped cream. In a separate bowl, mix the other 4 ingredients together, then gently fold the whipped cream into the peanut butter mixture. The result is a creamy, airy peanut butter filling.

Chocolate Ganache Topping

You only need 2 ingredients for the chocolate ganache topping: chocolate and heavy cream. You’ll simply pour warm cream over chocolate and stir. Use a quality chocolate because it’s where all of the flavor comes from. I would avoid using chocolate chips– use the real deal. Pure chocolate never lets you down. Never! See my chocolate ganache page if you need extra help with it.

You’ll want to make the ganache before the peanut butter layer because it must fully cool down prior to pouring over the peanut butter filling. This time also allows the ganache to thicken, creating a fudge-like consistency when the pie is ready to serve.

Crushed Reese’s Pieces

You’ll find crushed Reese’s Pieces in two places– on top of the Oreo crust and sprinkled on top of the chocolate ganache. They add a little crunch, a little color, and that little something extra! Instead of Reese’s Pieces, try crushed M&Ms or skip them all together.

Like peanut butter cup tart, the only baking we’ll do is for the crust. Other than that, the refrigerator does all the work. The pie must set up in the refrigerator for 5-6 hours. Overnight would be wonderful, but I’ve made this peanut butter pie twice with just 5 hours of chill time. Peanut butter perfection each time. This dessert is always fun for birthdays, but I’ve served it on Father’s Day, Mother’s Day, Valentine’s Day, anniversaries, a random Sunday (why not?), you name it. It’s always devoured!

Unbelievable Peanut Butter Pie

  • Author: Sally
  • Prep Time: 1 hour
  • Cook Time: 10 minutes
  • Total Time: 7 hours or overnight
  • Yield: 1 9-inch pie
  • Category: Pie
  • Method: Baking
  • Cuisine: American


The most unbelievable peanut butter pie! Complete with an Oreo cookie crust, Reese’s Pieces, chocolate ganache, this recipe is over the top in the best way.


Oreo Crust

  • 24 peanut butter Oreos (or regular, Double Stuf is ok!)
  • 5 Tablespoons (75g) unsalted butter, melted


  • 3/4 cup (180g) heavy cream
  • 6 ounces (170g) semi-sweet chocolate, coarsely chopped

Peanut Butter Filling

  • 3/4 cup (180ml) heavy cream
  • 8 ounce (224g) block cream cheese, softened to room temperature
  • 1 and 1/2 cups (310g) creamy peanut butter
  • 3/4 cup (90g) confectioners’ sugar
  • 1 teaspoon pure vanilla extract
  • 1 cup (200g) Reese’s Pieces, crushed


  1. Preheat the oven to 350°F (177°C). Spray a 9-inch pie dish with nonstick spray or grease lightly with butter.
  2. Make the crust: In a food processor or blender, pulse the whole Oreos into a fine crumb. Stir the cookie crumbs and melted butter together, then press into the pie dish. Bake for 9-10 minutes. Allow to cool as you prepare the rest.
  3. Make the ganache: Place chopped chocolate in a medium bowl. Heat the cream in a small saucepan over medium heat, stirring occasionally. Once it begins to boil, immediately remove from heat then pour over the chocolate. Stir gently until the ganache is smooth. Set aside and allow to cool to room temperature. During this time, it will slowly thicken as well.
  4. Make the filling: Using a hand mixer or a stand mixer fitted with a whisk attachment, beat the heavy cream on medium-high speed until stiff peaks form, about 5 minutes. Spoon the whipped cream into a bowl and set aside. Using the same mixing bowl (no need to rinse clean!), beat the cream cheese, peanut butter, confectioners’ sugar, and vanilla extract together on medium-high speed until combined. Mixture will be thick. Fold in the whipped cream until smooth. be gentle, you don’t want to deflate that cream.
  5. Sprinkle half of the Reese’s Pieces on top of the cooled crust. Spread peanut butter filling evenly on top, then spread ganache on top of filling. Sprinkle the rest of the Reese’s Pieces on top.
  6. Chill the pie in the refrigerator for 5-6 hours or even overnight. Slice and serve cold.


  1. Make Ahead & Freezing Instructions: You can get started on the crust in step 2 and the ganache in step 3. You can keep both in the refrigerator overnight if you’re getting started the day before. Cover both tightly. This pie can be frozen up to 3 months. It’s tasty frozen or you can let it thaw overnight in the refrigerator before serving.
  2. Peanut Butter: Use a non-natural peanut butter like Jif creamy or Skippy creamy. I do not suggest using natural style or oily peanut butter; both cause the filling to separate and/or turn greasy.

  1. Serious overload and that’s why I love this! Especially the crust.

  2. Laura | Tutti Dolci says:

    This is my kind of pie! That PB filling looks incredible and I could easily take a spoon to the ganache ;).

    1. The only way to do it. “taste testing/quality control”

  3. This dessert looks absolutely delicious! Creamy and rich xx
    Love this pie!

  4. This is possibly your most beautiful post yet and maybe even my new favourite. I’ll be showing this off at work today hoping for lots of ‘well why aren’t you making it then’

    1. Thanks Laura. I’ve been having trouble getting used to the new light in my home. So I REALLY appreciate that!

  5. heather (delicious not gorgeous) says:

    oh, that hidden bit of crushed reese’s right below the peanut butter filling makes this sound even better!! i love surprises in my food (:

    1. A secret layer 😉

  6. Anne Sportsmassage says:

    Love your recipes and images.
    Thanks for sharing yet another amazing recipe:-)

  7. Marina @ A Dancer's Live-It says:

    And I thought my Dad’s Peanut Butter Pie was insane…this recipe take it to a whole other level! Kevin is such a lucky guy to be spoiled with all of these desserts. 😉 This would be my birthday treat of choice too!

  8. I’m totally making this for my birthday next month. If I wait for my family to produce a suitable dessert, I’ll wind up crying on the floor. This is so incredible.
    And PB Oreos are cookie aisle George Clooneys. Seriously the best stand-out stars EVER. I like to inhale packages, so that makes life good!

    1. Lol the george clooneys 😀

  9. Dawn @ Girl Heart Food says:

    OMG….how good does this pie look?!! Have to make this one. I love peanut butter, but hubby even more so. I may just have to make 2 pies ’cause I don’t think one will do 😉 Pinned!

  10. Michelle @ Modern Acupuncture says:

    This looks freaking spectacular! OMG. I am trying to do low-carb (why? what is wrong with me?) but this… this will be happening in my life no matter what.

    1. I tried to do low carb a few summers ago. It’s very challenging! But maybe this can be a weekend treat for you.

  11. Rachel @ Mesa Cooking Co. says:

    Oh WOW. This is the ULTIMATE peanut butter pie. Looks like I cannot make this unless a large group is coming over or else I could easily eat this whole thing in one sitting!! Beautiful, too! 

    1. Definitely make sure you’ve got a large group because this one is a tempting calorie bomb!

  12. Michelle H. says:

    This looks BOMB! Like Kevin, I am all about all things chocolate and peanut butter. Quite frequently, I eat a spoon full of peanut butter with dark chocolate chips or Nutella. It makes for a nice snack. My birthday is this Saturday, and I’m thinking this pie needs to happen. Pie and ice cream is just as acceptable, if not more, than cake. Thanks!

    1. Peanut butter chocolate chips spoons are the best. Sometimes I do M&Ms instead!

      1. I’m glad to hear I’m not alone in the spoon snack of peanut butter and chocolate chips! Looking forward to this delicious pie!

      2. Making this pie again today, My sister is coming to visit for the weekend and loves the peanut butter chocolate combo as much as myself. Can’t wait for dessert tomorrow!!

  13. I’ve been waiting for you to come up with your own recipe of this! Thank you!

    1. The wait is over!

  14. Leah @ Grain Changer says:

    I have been absolutely DROOLING over this all week on Snapchat! So happy to finally have the recipe. We’re huge PB+Choc fans, too (best combo ever? Yes. 110% yes) so this is basically heaven on a plate. Kevin is one lucky birthday boy!

  15. Jennifer @ Show Me the Yummy says:

    OMG <– I have no other words. Been drooling over this since I saw your snapchat yesterday!!

  16. Ellen @ My Uncommon Everyday says:

    When it comes to fruit pie or fruit crisp, I’ll always be a crisp person. But I am SUCH a peanut butter pie person that i order it whenever it’s on the dessert menu. This looks like complete dessert perfection.

  17. Amazing! Sally you rock – I dont think a single one of your desserts have dissapointed… like ever! 😛 (munching on Reese’s butterscotch chewy cookies right this mo!) Quick q: after whisking the cream, and mixing the peanut butter cream cheese etc, switch to paddle attachment or keep whisk? Just checkin!  Oh and… Could you post more dog treats?!? My boy loooves your peanut butter carrot treats!! 

    1. Just keep the whisk. And no need to wash it clean either. And yes! I can work on more dog treats 🙂

  18. I’m in the market for birthday desserts, too! I don’t think there’s been a single year I’ve actually made a cake for my husband. One year I made him a cookie cake, the next year brownies, and last year I made him mini cheesecakes! His birthday is less than a month away and the inspiration just keeps on coming!

  19. This looks so amazingly decadent! Just in time for my sister’s birthday, she requested a peanut butter dessert and this is going to be perfect!

    Ever since the PB Skillet Cookie, I’ve been waiting for another amazing PB recipe from my fave PB blogger–er, I mean food blogger. 😉 Also, I wanted to say PB like 100 times in one sentence. Lolol.
    Thank goodness Kevin’s birthday is coming up! Please extend my greatest thanks to him for inspiring the creation of this pb choc on pb choc on pb oreos loveliness. I don’t think I blinked once during the entire reading/drooling/staring at this post. Woah. I didn’t even know there were PB oreos! Thanks for giving us a for-realsies reason to smile this extra humpy Wednesday. Okay, that sounded gross. Er… Off to slather some PB and choc on something… anything! 😉 xo

    1. Stop what you’re doing and try the peanut butter Oreos. They are honestly the best cookies from the store. Ever. Ever ever ever!

  21. Oh Sally – I can’t wait to make this!  PB & Choc is my favorite combo!  My hubby brought me home a carton of chocolate peanut butter ice cream the other day – it had peanut butter swirl, fudge swirl and little pieces of chopped up Reese cups in it. I served myself a scoop, took some Reese cups out of the pantry, chopped them up and put them on top of the ice cream. My husband says, “There’s Reese cups IN the ice cream.” I said, “You can NEVER have too many Reese cups. ” 🙂

    1. I’m nodding along as I read every sentence. Yes, yes, yes!

  22. Heck yeah! Kevin has good taste, even if he doesn’t like coffee. With that pie, his birthday will be just great! 🙂

  23. Sally, this is right up my alley. Chocolate and peanut butter is my favorite. However, I am lactose intolerant…and while I have a lactose free cream cheese, is there a way to sub the heavy whipping cream? There is a half & half that is lactose free, but that won’t whip very well, I would think. There is a coconut based “cool Whip” type thing, that is really good if you like coconut based things. Possibility?

    1. Heidi, I’ve been thinking about it and I think the coconut “cool whip” would be best here. I think the flavor would actually be VERY good.

      1. Thanks Sally! I can’t wait to try it!

  24. “In other words, it’s made of calories.” Awesome one-liner :). Also, this pie looks amazing!

    1. Ha!! Thanks Jenny.

  25. this dessert looks sooooo good

  26. Looks absolutely delicious. Huge fan of anything peanut butter so I’ll have to go this a go sometime. Thanks for sharing this recipe.

  27. OMG! Looks yummy. Best of all, it’s easy to make. Thank you.
