Ingredients for peanut butter pie with reese's peanut butter cups
Just 11 pantry staples transform into a decadent no-bake pie everyone will beg for.
| Ingredient | Amount | Notes |
|---|---|---|
| Peanut Butter 🥜 | 1 ½ cups | Creamy variety preferred |
| Sweetened Condensed Milk 🥛 | 14 oz | Standard can size |
| Unsalted Butter 🧈 | ½ cup | Softened for mixing |
| Reese's Peanut Butter Cups 🍫 | 12 whole | Mini or regular size |
| Vanilla Extract 🌿 | 1 tsp | Pure alcohol-free if preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Heavy Whipping Cream 🥛 | 1 cup | Cold for topping |
| Graham Cracker Crust 🍪 | 14.3 oz | Pre-made or homemade |
| Powdered Sugar 🍚 | 1 cup | For dusting crust |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For greasing pie dish |
| Dark Chocolate Chips 🍫 | ½ cup | Optional for garnish |
The peanut butter is the star—Creamy gives that perfect smooth texture, while natural adds extra richness. Trader Joe's or Jif are my go-tos, but any creamy brand works. Reese's cups? Grab the mini ones if you want extra crunch—Costco sells them in bulk for parties. The condensed milk can is non-negotiable; store-brand works fine as long as it's not expired. For the crust, pre-made Nilla Wafer crusts save time, but homemade graham cracker crust is worth the 10 extra minutes (I use Honey Maid for that classic flavor).
No Reese's cups? Melted peanut butter cups (like Hershey's) work in a pinch, though the crunch is missing. Short on condensed milk? Evaporated milk plus extra powdered sugar mimics the sweetness, but it won't be identical. The butter needs to be soft but not melted—microwave for 20 seconds if it's too firm. For the crust, if you're making it from scratch, toast the graham crackers first to prevent sogginess. And that powdered sugar? Confectioners' sugar is your friend here—it dissolves smoothly into the filling.
This pie keeps 5-7 days in the fridge, though it's best within 3 days. The filling firms up nicely, but if it gets too firm, pop it in the microwave for 10-15 seconds to soften. For serving, I like to add a dollop of whipped cream and a few chocolate chips on top—Ghirardelli semi-sweet work perfectly. Freezes beautifully for up to 2 months if you want to prep ahead. Just let it thaw in the fridge overnight before slicing.

Step-by-step instructions for peanut butter pie with Reese's peanut butter cups
This no-bake pie comes together faster than you'd expect—creamy layers, fudgy swirls, and all the Reese's magic.
Prepare the Graham Cracker Crust
Grease a 9-inch pie dish with 1 tablespoon extra-virgin olive oil, then press the 14.3 oz graham cracker crust firmly into the bottom and up the sides. Use a glass to compact it evenly—this prevents crumbling later. Chill the crust in the freezer for 10 minutes while you make the filling. The cold crust stays sturdy when you pour the warm peanut butter mixture over it.
Here's the thing—don't skip the chilling step. A warm crust will melt from the filling, making your pie soggy instead of perfectly set. I like to use my hands to press the crust into every corner, ensuring complete coverage. If you have leftover crust pieces, crush them and sprinkle them around the edges for extra crunch.
Make the Peanut Butter Filling
In a medium saucepan, combine the 1.5 cups peanut butter, 14 oz sweetened condensed milk, 0.5 cup unsalted butter, 1 tsp vanilla extract, and 0.25 tsp salt. Cook over medium-low heat, stirring constantly with a wooden spoon, until everything melts together smoothly. This should take about 5-7 minutes—you'll know it's ready when the mixture looks glossy and uniform.
Watch the heat carefully. If you let it bubble, the filling will seize and become grainy. Once it's completely smooth, remove from heat and let it cool for 10 minutes. The mixture will thicken as it cools, which is exactly what we want for that perfect pie consistency. Here's where it gets fun—taste a spoonful. If it needs more sweetness, add 1-2 tablespoons of powdered sugar to balance the flavors.
Create the Reese's Swirls
While the filling cools, prepare the Reese's swirls. Unwrap 8 of the 12 whole Reese's peanut butter cups and chop them into small, irregular pieces—think about ¼-inch chunks. Set these aside. Melt the remaining 4 whole Reese's peanut butter cups in a microwave-safe bowl in 20-second intervals, stirring between each, until completely smooth. You want a thick, fudgy consistency that will swirl beautifully.
This is the moment that matters: carefully pour the melted Reese's mixture into the cooled peanut butter filling, then gently swirl it with a knife or spoon. Don't overmix—just create those signature marbled patterns. The contrast between the creamy peanut butter and the fudgy Reese's is what makes this pie irresistible. If you're worried about the texture, don't be. The filling will hold its shape once chilled.
Assemble and Chill the Pie
Pour the peanut butter-Reese's mixture over the chilled graham cracker crust, spreading it evenly. Tap the pie dish gently on the counter to release any air bubbles. Sprinkle the 0.5 cup dark chocolate chips evenly over the top for extra richness—this is optional but adds a beautiful contrast. Let the pie sit at room temperature for 30 minutes to set slightly before chilling.
Real talk: patience is key here. Transfer the pie to the refrigerator and chill for at least 4 hours, or preferably overnight. This ensures the filling sets completely and the flavors meld together perfectly. I know it's hard to wait, but trust me—this chilling time is what transforms your pie from good to extraordinary. The crust will hold its shape, and every slice will have that perfect balance of creamy and crunchy.
Whip the Cream and Serve
Just before serving, whip the 1 cup heavy whipping cream with a hand mixer until it forms soft peaks. Spoon the whipped cream over the chilled pie, then dust generously with 1 cup powdered sugar using a fine-mesh sieve. This creates that signature dusting that makes the pie look (and taste) like it came from a bakery. Serve immediately so the cream stays fluffy and light.
Slice with a warm knife for clean cuts, and watch as the peanut butter filling oozes out with every bite. The contrast of the cool, creamy filling against the crunchy crust and the fudgy Reese's swirls is pure magic. This pie keeps well in the refrigerator for up to 5 days, though I doubt it will last that long in your house. Enjoy every last bite—it's worth the effort!
Pro Tips For Making Peanut Butter Pie With Reese'S Peanut Butter Cups
- Chill the Peanut Butter First: Skip the grainy texture by refrigerating your peanut butter for at least 30 minutes before mixing. I learned this the hard way—room-temperature peanut butter turns into a thick, clumpy mess when combined with condensed milk and butter, no matter how much you stir.
- Chop Reese’s Evenly: Use a sharp knife or food processor to crush Reese’s into small, uniform pieces—about the size of a pea. Big chunks melt unevenly and leave you with a pie that’s more "explosive" than smooth. (Yes, I’ve seen it happen.)
- Don’t Overmix the Filling: Stir the peanut butter mixture just until combined—about 2 minutes by hand. Overworking it heats the condensed milk too fast, which can cause the pie to set prematurely or even curdle. Let the residual heat from the ingredients do the work.
- Press Crust Firmly: Pack the crust into the pan with your hands, pressing down hard in the center to prevent a soggy bottom. I used to just press lightly, and the pie would leak filling like a sad, greasy puddle. (No one wants that.)
Serving suggestions for this peanut butter pie with reese's peanut butter cups
Whipped Cream Topping
No peanut butter pie is complete without a cloud of whipped cream—it adds a light, airy contrast to the rich filling. I whip 1 cup heavy whipping cream with a hand mixer until soft peaks form, then gently spoon it over the chilled pie.
For extra flair, dust with 1 cup powdered sugar using a fine-mesh sieve to create that bakery-style finish. Pro tip: Use a KitchenAid stand mixer for ultra-smooth peaks in just 2-3 minutes. 🥛
Chocolate Drizzle
For a showstopping presentation, melt ½ cup dark chocolate chips with 1 teaspoon coconut oil in a double boiler, then drizzle in artistic swirls over the pie. I like to use Ghirardelli 60% dark chocolate for its perfect balance of bitterness and sweetness.
Let the chocolate set slightly before serving—it adds a sophisticated touch that elevates the dessert from homemade to restaurant-quality. 🍫
Crushed Reese's Topping
Save the remaining 4 Reese's peanut butter cups for a crunchy topping. Pulse them in a food processor until you get ¼-inch chunks, then sprinkle evenly over the pie before chilling.
The contrast of warm, melted peanut butter filling against cool, crunchy Reese's bits is what makes this pie unforgettable. For extra crunch, toast the crushed pieces in a 350°F oven for 3-4 minutes before sprinkling. 🥜
Vanilla Bean Garnish
For a refined touch, split a vanilla bean, scrape out the seeds, and sprinkle them over the whipped cream. The aromatic notes complement the peanut butter perfectly. I also like to add a few thin chocolate shavings from a microplane for an elegant presentation.
This garnish works especially well for special occasions or when serving guests. ✨
Peanut Butter Drizzle
Warm 2 tablespoons creamy peanut butter in a microwave-safe bowl for 10-15 seconds, then drizzle it over the pie in zigzag patterns. The warm peanut butter will slightly soften the crust edges, adding another layer of flavor and texture.
This step is optional but adds a professional finish that makes the pie look like it came from a dessert buffet. 🥜
Serving Suggestions
Serve this pie chilled for the best texture—scoop generous slices onto plates and add a dollop of whipped cream. For a fun twist, serve it in small jars with a spoon for individual portions. Pair with a glass of cold milk or a cup of coffee to balance the richness.
I often make this pie ahead for parties—it keeps well for 5 days in the fridge, so you can enjoy it without the rush. 💫

Frequently asked questions
Can I make this peanut butter pie without Reese's cups?
The Reese's cups are what give this dessert its signature flavor and texture! For a substitute, try melting ½ cup peanut butter chips and ¼ cup chocolate chips together to mimic the fudgy swirls. The crunch will be different, but the peanut butter flavor will still shine through.
How long does it need to chill before serving?
The pie needs at least 4 hours in the fridge to set properly, but overnight chilling gives the best texture. If you're short on time, try freezing it for 1 hour—just let it sit at room temperature for 10 minutes before slicing to soften slightly.
Why did my filling get grainy?
Graininess usually happens when the mixture overheats or isn't stirred constantly. Keep the heat at medium-low and stir with a wooden spoon until completely smooth. If it starts to seize, remove from heat immediately and stir vigorously. A splash of warm milk can help restore smoothness.
Can I use a different crust?
This filling works beautifully with Nilla Wafer, Oreo, or even a gingersnap crust. For a lighter option, try a graham cracker crust with 1 tablespoon melted butter mixed into the crumbs before pressing. The crust just needs to be sturdy enough to hold the creamy filling.
How do I store leftovers?
Cover tightly with plastic wrap and store in the fridge for up to 5 days. To reheat, microwave individual slices for 10-15 seconds to soften the filling. For freezing, wrap the whole pie in plastic and foil, then freeze for up to 2 months. Thaw overnight in the fridge.
