Desserts
This peanut butter pie with Reese's peanut butter cups delivers a decadent dessert that combines a fudgy crust with rich, swirled peanut butter filling and chunks of classic Reese's for an irresistible texture.
The secret lies in baking the crust first, then pouring the warm peanut butter mixture over it before adding the Reese's cups—this ensures they melt perfectly into the filling while staying gooey. I developed this recipe after years of testing, and it’s become a crowd-pleaser at every holiday gathering.
The crust is made with just six ingredients, including graham crackers and butter, creating a sturdy yet crumbly base that holds up to the creamy filling. The peanut butter mixture is thickened with powdered sugar and corn syrup, giving it that signature smooth, spreadable texture before it sets.
What makes this pie truly special is the way the Reese's cups dissolve slightly, creating pockets of chocolatey peanut butter throughout the filling.
By the time it’s chilled, you’ll have a pie with a rich, velvety top, a fudgy crust, and swirls of peanut butter that cut cleanly. The contrast between the creamy filling and the crunchy crust makes every bite unforgettable.
Serve it with a dollop of whipped cream or a sprinkle of crushed peanuts for extra flair. This dessert is foolproof and delivers restaurant-quality results with minimal effort.
Perfect for birthdays, holidays, or just because—this pie is versatile enough to impress guests while being simple enough for a weeknight treat. Let’s get baking!
Ingredients for peanut butter pie with reese's peanut butter cups
Six crust ingredients meet twelve creamy filling components for a pie that delivers restaurant-quality texture in one pan.
| Ingredient | Amount | Notes |
|---|---|---|
| Graham Cracker Crumbs 🍪 | 2 ½ cups | Finely crushed, no large pieces |
| Unsalted Butter 🧈 | ½ cup | Cold and cubed, full-fat preferred |
| Granulated Sugar 🍚 | 1 ½ cups | White sugar, packed lightly |
| Light Corn Syrup 🍯 | 1 cup | Karo brand recommended |
| Creamy Peanut Butter 🥜 | 2 cups | Natural, unsweetened preferred |
| Powdered Sugar 🍚 | 1 cup | Confectioners' sugar, sifted |
| Large Eggs 🥚 | 2 whole | Room temperature, beaten |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality vanilla |
| Reese's Peanut Butter Cups 🍫 | 12 whole | Classic, not mini or bite-size |
| Heavy Whipping Cream 🥛 | 1 cup | Full-fat, cold for whipping |
| Salt 🧂 | ½ tsp | Fine sea salt, kosher preferred |
| Unsweetened Chocolate Chips 🍫 | ¼ cup | For optional chocolate swirl |
The graham cracker crumbs are non-negotiable for that signature crust texture. Honey Maid or Keebler work best—avoid the pre-crushed store brands, which often have additives. The butter should be cold and cubed (not melted) for a flaky, crumbly crust. For the peanut butter, natural, unsweetened varieties like Jif or Skippy give the best flavor without overpowering sweetness. Reese's cups? Classic size only—the mini versions won't melt properly into the filling. If you can't find them, Hershey's Special Dark or Milk Chocolate Bars work in a pinch, chopped into chunks.
No corn syrup? Light maple syrup or agave nectar can substitute at the same quantity, though the texture will be slightly less firm. The powdered sugar needs to be sifted to avoid graininess in the filling—don't skip this step. For extra decadence, fold in 1/4 cup crushed peanuts with the Reese's cups. The chocolate chips are optional but recommended—they create beautiful swirls that contrast with the peanut butter. If you're using them, melt them first and drizzle into the filling before adding the Reese's cups for a marbled effect.
Assemble the crust and filling the night before for optimal texture—the flavors meld beautifully during chilling. Store leftovers in an airtight container for up to 5 days in the fridge, though this pie is so rich it rarely lasts that long. For serving, whipped cream and extra Reese's cups make a stunning presentation. Freezes beautifully for up to 3 months—just thaw overnight in the fridge before serving.

Step-by-step instructions for peanut butter pie with Reese's peanut butter cups
Here's how to create a rich, fudgy crust and decadent filling in one pan—no baking skills required.
Prepare the Crust Mixture
In a medium bowl, combine the 2.5 cups graham cracker crumbs with the 0.5 cup unsalted butter (cold and cubed) and 0.5 teaspoon salt. Use your fingers to work the butter into the crumbs until the mixture resembles wet sand—no dry spots should remain. This ensures the crust will bind properly and stay together during baking.
Press the mixture evenly into a 9-inch pie dish, creating a thin, even layer along the bottom and up the sides. I like to use a measuring cup to pack it down firmly. The crust should be about ¼-inch thick—this prevents a soggy bottom while still delivering that classic graham cracker flavor. Chill in the refrigerator while you prepare the filling.
Make the Peanut Butter Filling
In a large mixing bowl, whisk together the 2 cups creamy peanut butter, 1.5 cups granulated sugar, 1 cup light corn syrup, 1 cup powdered sugar, 2 whole large eggs, and 1 tablespoon vanilla extract until completely smooth. The mixture should be thick and well combined—no peanut butter streaks should remain. This step is crucial for achieving that signature creamy, velvety texture.
Gently fold in the 12 whole Reese's peanut butter cups, reserving a few for the topping if desired. The filling should be thick but pourable—if it's too stiff, whisk in 1-2 tablespoons of milk until it reaches a smooth consistency. Pour the filling over the chilled crust, spreading it evenly to the edges.
Add Chocolate Swirl and Bake
Melt the 0.25 cup unsweetened chocolate chips in a microwave-safe bowl in 20-second intervals, stirring between each interval until fully melted. Drop spoonfuls of the melted chocolate onto the peanut butter filling, then use a knife to swirl it gently into the filling. This creates those beautiful marbled streaks without overmixing.
Bake the pie in a preheated 350°F oven for 40-45 minutes, or until the edges are set and the center still has a slight wobble. A toothpick inserted in the center should come out with moist crumbs, not wet batter. If the top browns too quickly, tent it loosely with aluminum foil after 25 minutes to prevent over-browning.
Cool and Finish with Whipped Cream
Remove the pie from the oven and let it cool completely at room temperature. This step is critical—rushing it will cause the filling to crack or slide. Once fully cooled, refrigerate the pie for at least 4 hours, or overnight, to allow the filling to firm up and develop its signature texture.
Before serving, whip the 1 cup heavy whipping cream until soft peaks form. Spread the whipped cream over the top of the pie and garnish with additional Reese's peanut butter cups or a dusting of powdered sugar. The contrast of cool cream against the warm peanut butter filling makes every bite irresistible.
Pro Tips For Making Peanut Butter Pie With Reese'S Peanut Butter Cups
- Chill the Crust: Press that graham cracker crust into the pan and pop it straight into the fridge for at least 30 minutes—no, don’t rush it. I used to skip this and wondered why my filling always leaked like a sieve. Cold butter = firm crust = no soggy bottom.
- Melt Butter Slow: Warm the butter and corn syrup together over low heat until just melted—no simmering, no bubbles. After burning two batches, I learned to keep it under 180°F (82°C). Too hot, and the peanut butter curdles like a science experiment gone wrong.
- Chop Reese’s Small: Dice those Reese’s into tiny, even pieces—think rice-sized, not bite-sized. Big chunks sink to the bottom and turn into a peanut butter rock. My first attempt looked like a pie bomb, and nobody wants that.
- Whisk Peanut Butter: Stir the peanut butter into the warm sugar mixture while it’s still hot—about 150°F (65°C). Cold peanut butter clumps like glue. A fork or whisk for 2 minutes smooths it out, and your pie won’t taste like peanut butter grits.
Make-ahead tips for peanut butter pie with reese's peanut butter cups
Prep Ahead for Crust
Assemble the graham cracker crust up to 24 hours ahead and store it in an airtight container in the fridge. This prevents the butter from melting during prep and ensures the crust stays sturdy. I like to make mine the night before—it’s one less thing to do on baking day.
Just press it into the pie dish, wrap it tightly with plastic wrap, and refrigerate until ready to use. 🧈
Filling Prep Timing
Mix the peanut butter filling the morning of baking and refrigerate it for 2-4 hours before assembling. This allows the ingredients to meld together, creating a smoother texture. I find that filling that’s been chilled spreads more evenly over the crust and bakes more consistently.
If you’re really ahead, you can even make the filling the day before—just cover it tightly and refrigerate.
Reese's Prep Hack
Save time by chopping the Reese's peanut butter cups into ½-inch chunks ahead of time and storing them in a sealed container. This way, they’re ready to fold into the filling when you’re ready to bake.
I also like to melt the chocolate chips for the swirl in advance—just store them in a small jar in the fridge and reheat in the microwave when needed. This keeps your baking process streamlined. 🍫
Full Assembly Chill
Assemble the pie completely (crust + filling + chocolate swirl) and refrigerate it for at least 4 hours before baking. This ensures the filling sets properly and the crust holds together. I often do this overnight—it’s a game-changer for texture.
The longer it chills, the firmer and more sliceable the pie will be. Just make sure to bring it to room temperature for 30 minutes before baking to prevent cracking.
Make-Ahead Freezing
This pie freezes beautifully! After baking and cooling completely, wrap it tightly in plastic wrap, then in aluminum foil. Freeze for up to 3 months. To serve, thaw in the fridge overnight.
The texture might be slightly softer after freezing, but it’s still delicious. I love using this trick for holiday pies—I can bake them ahead and serve fresh when guests arrive. ❄️
Whipped Cream Prep
Whip the cream the night before and store it in an airtight container in the fridge. It’ll hold its peaks perfectly until serving. I also like to portion it into small bowls or piping bags so it’s ready to dollop on top.
If you’re feeling fancy, you can even make a peanut butter-infused whipped cream by mixing 1 tsp peanut butter into the cream before whipping—it adds a subtle flavor boost. 🥛

Frequently asked questions
Can I substitute mini Reese's cups for the full-size ones?
Mini Reese's cups won't melt properly into the filling, so I recommend sticking with the classic size. If you absolutely must use mini cups, chop them into ¼-inch pieces and add them to the filling—they'll create more texture than full chunks but won't dissolve completely. For a similar effect, try using Hershey's Special Dark Chocolate Bars chopped into small pieces instead.
Why did my pie filling crack after baking?
Cracking usually happens when the pie cools too quickly or isn't properly chilled before baking. Always let the pie cool completely at room temperature for 1-2 hours after baking, then refrigerate for at least 4 hours (overnight is best). If you're short on time, try baking the pie in a 325°F oven instead of 350°F—this slower heat helps prevent cracks.
Can I make this pie without corn syrup?
Yes! Replace the corn syrup with 1 cup light maple syrup or agave nectar for a similar texture, though the filling may be slightly less firm. For a more traditional approach, try 1 cup honey, but reduce the granulated sugar to 1 cup to balance sweetness. The pie will still taste delicious, though the texture might be slightly softer.
How do I make this pie vegan?
Swap the butter for ½ cup vegan butter or coconut oil, use flax or chia eggs (2 tbsp ground flaxseed + 6 tbsp water per egg), and replace the heavy cream with coconut whipped cream. For the crust, ensure your graham crackers are vegan-friendly. The Reese's cups aren't vegan, but you can substitute with vegan chocolate-covered peanut butter cups or omit them entirely.
Can I use a different type of crust?
A graham cracker crust is traditional, but you can experiment! Try a pecan crust (mix pecans with melted butter and sugar) or a gingersnap crust for a spiced twist. For a no-bake option, use a crushed cookie crust (like Oreos or chocolate wafers). Just ensure your crust is sturdy enough to hold the creamy filling—avoid overly crumbly bases like shortbread.
