Desserts
This giant Reese's peanut butter cup pie recipe delivers restaurant-quality decadence without a single trip to the oven. The secret lies in three distinct layers—crispy crust, creamy peanut butter filling, and a showstopping Reese’s cup topping—that come together in under an hour.
I perfected this no-bake dessert after years of testing, ensuring every slice delivers that perfect balance of chocolatey, nutty, and creamy perfection.
The foundation starts with a buttery graham cracker crust, pressed into the pan and chilled until firm. Next comes the star: a velvety peanut butter filling made with melted Reese’s cups, powdered sugar, and heavy cream, whipped to a smooth, spreadable consistency.
What sets this apart is the final layer—whole Reese’s cups pressed into the filling before it sets, creating a marbled effect that looks as impressive as it tastes.
By the time you slice into this pie, you’ll have a dessert that’s rich, creamy, and packed with that signature Reese’s flavor in every bite.
The crust stays crisp, the filling holds its shape, and those melted peanut butter cups create pockets of gooey goodness that’ll have everyone asking for seconds. This is the kind of dessert that transforms any gathering into a celebration.
Scaling up or down is simple—just adjust the crust and filling proportions while keeping the Reese’s cup layer intact. For extra flair, garnish with whipped cream or a drizzle of melted chocolate before serving. The no-bake method means no oven heating, no waiting, and all the indulgence. Let’s get baking!

Graham crackers are the backbone here. Honey Maid or Keebler work perfectly, but if you've got a favorite brand, use it. The butter matters—full-fat is non-negotiable for that rich, buttery crust. I grab mine from Trader Joe's when it's on sale, but any store-brand works. For the peanut butter cups, mini size is a game-changer—they distribute evenly and create those perfect pockets of gooey goodness. If you're using the full-size cups, chop them into quarters first. The powdered sugar? Domino brand is my go-to because it's consistently fine and sifted.
No Reese's peanut butter cups? Crushed peanut butter cups plus powdered sugar can work in a pinch, but it won't have that same signature texture. Short on graham crackers? Crushed vanilla wafers or shortbread cookies add a different buttery flavor. The whipped cream can be store-bought, but homemade with a pinch of vanilla takes it to the next level. For the melted chocolate drizzle, Ghirardelli squares melt beautifully—just chop them finely first. And if you're feeling extra, add a sprinkle of crushed peanuts on top for crunch.
This pie keeps beautifully—5 days in the fridge if stored properly. Wrap the whole thing tightly in plastic wrap, then place it in an airtight container. For longer storage, freeze for up to 3 months. Let it thaw in the fridge overnight before serving. The crust stays crisp, the filling stays creamy, and those Reese's cups? They just get gooier. I always make a double batch—half for now, half for later. Trust me, it’s worth the extra effort.

Step-by-step instructions for giant Reese's peanut butter cup pie
Here's how to build this showstopper pie with three layers of peanut butter bliss—no oven required.
Create the Crunchy Graham Cracker Base
Crush the 4 cups of graham crackers into fine crumbs using a food processor or rolling pin. I like to pulse them in batches for even consistency—you want the texture to be like coarse sand. In a large bowl, mix these crumbs with the 0.5 cup melted unsalted butter, 2 cups powdered sugar, 1 tsp vanilla extract, and 0.25 tsp salt until everything is thoroughly combined and looks like wet sand.
Press this mixture firmly into the bottom of your 9-inch large pie pan, using the plastic wrap to help you compact it evenly. The base should be about ¼-inch thick. Place the pie pan in the refrigerator while you prepare the filling—this chilling step is crucial for keeping the crust intact during assembly. Real talk: if you skip this, your crust might crumble when you add the heavy filling later.
Prepare the Peanut Butter Cup Filling
In a medium bowl, whip the 1.5 cups cold heavy whipping cream until it forms soft peaks. Gently fold in the 32 whole mini Reese's peanut butter cups, being careful not to break them. The filling should look like a creamy peanut butter swirl with whole cups evenly distributed throughout. This is where the magic happens—those whole cups will melt slightly when chilled, creating pockets of gooey peanut butter heaven.
Spread this filling evenly over the chilled graham cracker crust, pressing down gently with a spatula to create a smooth surface. You want the filling to reach just below the edge of the crust—this ensures every bite has that perfect ratio of crunch to creamy peanut butter. Return the pie to the refrigerator while you prepare the topping layer.
Assemble the Top Layer of Whole Reese's
Arrange the 24 whole whole Reese's peanut butter cups in a single layer on top of the peanut butter filling, pressing them down gently so they sit flat against the surface. You'll want them to touch each other slightly—this creates a continuous layer of peanut butter when they melt. If any of the cups are too large to fit neatly, you can trim a tiny bit from the sides with a sharp knife to make them fit.
Once all the whole Reese's are in place, cover the pie with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. This long chilling time is what transforms this assembly into a perfect pie—it allows the filling to set properly while the peanut butter cups melt just enough to create that signature gooey texture without turning to mush.
Add the Final Creamy Topping
Before serving, spread the 1 cup whipped cream evenly over the entire surface of the pie. This adds a beautiful contrast to the rich peanut butter layers and gives each slice that extra-luxurious finish. For an optional drizzle that takes this pie to the next level, gently warm the 0.5 cup melted chocolate until it's smooth, then carefully pour it over the whipped cream in thin streams. Let it set for 10-15 minutes before slicing.
Slice this pie with a warm knife for clean cuts, and serve immediately. The contrast of the crunchy graham crust, creamy peanut butter filling, and smooth chocolate drizzle makes every bite a celebration. Trust me, this pie is so rich that you might want to make two—it disappears fast!
Pro Tips For Making Giant Reese'S Peanut Butter Cup Pie
- Pulse, Don’t Grind: DESCRIPTION: Your food processor will hate you if you dump all the graham crackers in at once. Pulse in batches—30 seconds on, 10 off—until you get that fine, sand-like texture. Too fine, and you’ll end up with a paste; too coarse, and your crust will taste like chewed-up graham cracker bits. (I learned this after one very crumbly disaster.)
- Melt Butter Slow: DESCRIPTION: Warm the butter in a saucepan over low heat until it’s just melted and barely bubbling—about 2 minutes. If you crank the heat, it’ll brown and turn bitter, and your crust will taste like a campfire. Stir occasionally, but don’t walk away; burned butter ruins everything.
- Chill the Filling: DESCRIPTION: Let the peanut butter cup mixture cool completely before pouring it into the crust. If it’s still warm, the graham cracker base will turn soggy faster than you can say “peanut butter drip.” Pop it in the fridge for 15 minutes—trust me, your pie’s life depends on it.
- Whip Cream to Stiff Peaks: DESCRIPTION: Don’t stop at soft peaks—whip the heavy cream until it holds firm peaks that don’t wobble when you lift the whisk. Overmixing? No, not here. You want that cloud-like texture to stay put, not slide into a puddle. (And yes, even if you’re impatient like me.)
Make-ahead tips for giant reese's peanut butter cup pie
Crust Prep Ahead
Make your graham cracker crust up to 2 days in advance—it keeps beautifully in an airtight container at room temperature. I like to press it into the pie pan, wrap it tightly in plastic, and refrigerate.
This head start saves time later and ensures a perfectly crisp base. For extra stability, chill the crust for 30 minutes before adding the filling to prevent crumbling. 🧂
Filling Prep Timeline
The peanut butter filling can be prepped 1 day ahead and stored in the fridge in an airtight container. Whip the cream and fold in the mini Reese’s cups, then cover with plastic wrap pressed directly on the surface to prevent a skin from forming.
When ready to assemble, simply spread it over the chilled crust—no re-whipping needed. This step makes the whole process feel effortless. 🥛
Layering Strategy
Assemble the entire pie—crust, filling, and Reese’s cup topping—up to 4 hours before serving. The key is pressing the whole Reese’s cups firmly into the filling so they create a marbled effect when they soften.
Cover tightly with plastic wrap and refrigerate. The longer it chills, the more those peanut butter cups will melt into the filling, creating that signature gooey texture. 🍫
Chilling Optimization
For maximum flavor development, chill the pie overnight—this is where the magic happens. The cold temperatures allow the peanut butter cups to melt just enough to blend with the cream, while keeping the crust perfectly crisp.
I often set my pie on the counter to come to room temperature for 30 minutes before adding the whipped cream topping, so it’s easier to spread. This timing trick ensures clean slices every time. ❄️
Freezer-Friendly Assembly
This pie freezes beautifully for up to 3 months if you assemble it completely (including the whipped cream topping) and wrap it tightly in plastic wrap followed by aluminum foil. Let it thaw in the fridge overnight before serving.
The texture remains perfect—crust stays crisp, filling stays creamy, and those Reese’s cups maintain their gooey integrity. Just avoid freezing with chocolate drizzle, as it can become grainy. 💫
Make-Ahead Garnishes
Prep your garnishes separately to save time. Whip the cream and melt the chocolate 1 hour before serving—these components are best added fresh. Store the whipped cream in a chilled bowl with plastic wrap pressed on the surface, and keep the melted chocolate in a heatproof container.
This way, you’re ready to assemble the final touches without stress when guests arrive. 🍦

Frequently asked questions
Can I make this pie without Reese’s peanut butter cups?
The magic of this dessert comes from those signature peanut butter cups! For a substitute, try melting 2 cups of creamy peanut butter with 1 cup powdered sugar and ½ cup melted butter, then folding it into the whipped cream. While it won’t be identical, it’ll still be delicious. The texture won’t be as gooey, but the flavor will be close.
How do I prevent the crust from getting soggy?
Chill the crust for at least 30 minutes before adding the filling—this is key! Also, press the crust firmly into the pan and use a springform pan if possible. For extra insurance, spread a thin layer of melted chocolate or whipped cream between the crust and filling to create a moisture barrier.
Can I use full-size Reese’s cups instead of mini ones?
Yes, but you’ll need to adjust the recipe! Use 16 full-size cups for the filling layer (chopped into quarters) and 12 full-size cups for the topping. The filling will be thicker, so press it down firmly with a spatula. The flavor will be even more intense, but the texture will be slightly denser.
Why did my filling turn grainy?
This usually happens when the cream isn’t cold enough or if the Reese’s cups melt too much before chilling. Always use cold heavy cream and whip it just to soft peaks. Fold in the cups gently, and refrigerate immediately. If it’s already grainy, try blending it briefly with a hand mixer to smooth it out before spreading.
How do I serve this pie for a crowd?
Double the recipe and use a 12-inch springform pan for a showstopper! For easy serving, slice it into wedges and arrange on a platter with extra whipped cream and chocolate shavings. Keep the pie chilled until serving—it’s too rich to sit out for long. A pie server makes clean slices effortless!
