Ingredients for giant reese's peanut butter cup pie
Fourteen ingredients for a dessert that’ll wow your crowd—rich, fudgy, and perfectly balanced.
| Ingredient | Amount | Notes |
|---|---|---|
| Oreo Cookies 🍪 | 40 whole | Crushed into fine crumbs |
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed for crust |
| Peanut Butter 🥜 | 2 ½ cups | Creamy, natural style |
| Semi-Sweet Chocolate Chips 🍫 | 2 cups | High-quality, not baking chips |
| Heavy Cream 🥛 | 1 ½ cups | Cold, full-fat preferred |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Powdered Sugar 🍚 | ½ cup | For dusting top |
| Large Eggs 🥚 | 4 whole | Room temperature |
| Vanilla Extract 🍯 | 2 tsp | Pure, not imitation |
| Salt 🧂 | 1 tsp | Fine sea salt |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Crushed Oreos 🍪 | 1 cup | For pie rim garnish |
| Chocolate Shavings 🍫 | ¼ cup | Dark chocolate preferred |

The Oreo crust is your foundation, so don’t skip crushing those cookies finely. Trader Joe’s sells pre-crushed Oreos if you’re short on time, but I always crush mine myself for that perfect texture. For the butter, use cold cubes—this keeps the crust flaky and prevents melting. The peanut butter? Natural, no-stir is best—it’s creamier and has that authentic Reese’s flavor. Grab a big jar of Hershey’s Special Dark chocolate chips if you want that classic taste, or go with Ghirardelli for extra richness. Pro tip: Toast your chocolate chips for 2 minutes in the microwave to deepen the flavor—trust me, it’s worth it.
No peanut butter? Substitute with 2 cups of creamy almond butter, though the flavor will shift slightly. Short on Oreos? Use 30 graham crackers for the crust—just crush them extra fine. The heavy cream needs to be cold for the filling to set properly, so chill your bowl and whisk before starting. Want extra Reese’s flavor? Add 1/2 cup of Reese’s Pieces to the filling before baking. For the chocolate shavings, a $10 microplane from Williams Sonoma makes this task effortless—no more struggling with a knife. And if you’re feeling fancy, swap the whipped cream for homemade whipped cream with a hint of vanilla bean.
This pie tastes even better the next day—make it ahead and store at room temperature for up to 3 days. For longer storage, cover tightly and refrigerate for up to 1 week. The crust stays crispy if you keep it sealed, and the filling stays luscious. To serve, slice with a warm knife for clean edges. Leftovers? Freeze individual slices for up to 2 months—just thaw at room temp before serving. And if anyone asks, the secret is patience: slow baking prevents cracks, and letting it cool completely keeps everything intact.

Step-by-step instructions for giant Reese's peanut butter cup pie
This decadent pie combines a buttery Oreo crust with a rich peanut butter-chocolate swirl filling. Let's build it layer by layer!
Create the Ultimate Oreo Crust
Preheat your oven to 350°F. Pulse the 40 whole Oreo Cookies in a food processor until you have fine crumbs—about 1½ cups. Mix these with the 1.5 cups Unsalted Butter (cold and cubed) until the mixture resembles wet sand. Press this firmly into a 9-inch pie dish, creating an even base and sides about ½-inch thick. Chill in the fridge while you prepare the filling.
For extra flavor, I like to add 1 tablespoon of the 2.5 cups Peanut Butter to the crust mixture. This ensures the first bite delivers that classic Reese's taste. Bake the crust for 10 minutes, then let it cool completely before adding the filling—this prevents a soggy bottom.
Whip Up the Peanut Butter Filling
In a large bowl, beat the 2.5 cups Peanut Butter with the 2 cups Granulated Sugar until completely smooth. Add the 4 whole Large Eggs, 2 tsp Vanilla Extract, and 1 tsp Salt, mixing until fully combined. In a separate bowl, whisk the 1.5 cups Heavy Cream and 0.5 cup Milk together, then gently fold this into the peanut butter mixture.
This is where the magic happens. The filling should be thick but pourable—if it's too stiff, whisk in 1 tablespoon of the 0.5 cup Milk at a time until it reaches the perfect consistency. Pour half of this mixture into the chilled pie crust, spreading it evenly to the edges.
Layer the Chocolate Swirl
Melt the 2 cups Semi-Sweet Chocolate Chips in a microwave-safe bowl in 30-second intervals, stirring between each, until completely smooth. Stir in ½ cup of the 2 cups Whipped Cream to create a glossy, rich chocolate layer. Pour this over the peanut butter layer, then use a knife to swirl the two together—think marbled cake, but even more dramatic!
Top with the remaining peanut butter mixture, spreading it evenly. The contrast between the smooth peanut butter and ribbons of chocolate is what makes this pie extraordinary. For extra indulgence, sprinkle ½ cup of the 1 cup Crushed Oreos over the top before baking.
Bake to Golden Perfection
Bake at 350°F for 45-50 minutes, until the edges are set and the center still jiggles slightly. Let it cool completely in the pan—this takes at least 2 hours, but patience is key for clean slices. While it cools, whip the remaining 1½ cups Whipped Cream until stiff peaks form.
Once fully cooled, spread the 2 cups Whipped Cream over the pie, then sprinkle with the 0.25 cup Chocolate Shavings and remaining ½ cup Crushed Oreos. Chill for at least 4 hours before serving—this allows the flavors to meld and the texture to set perfectly.

Flavor customization for these flavors
Spicy Reese’s Twist
Add a kick by stirring ½ teaspoon of cayenne pepper into the peanut butter filling before baking. For a milder heat, use 1 teaspoon of Penzeys brand chili powder—it adds smoky depth without overwhelming the sweetness.
I’ve tested this with Reese’s Pieces mixed into the filling, and the cayenne brings out their chocolatey notes beautifully. 🌶️
Salted Caramel Swirl
Replace the chocolate swirl with a caramel layer by heating 1 cup of granulated sugar in a saucepan until melted and amber-colored. Slowly whisk in ½ cup heavy cream and 2 tablespoons butter, then stir in 1 teaspoon flaky sea salt.
Pour this over the peanut butter layer before adding the final peanut butter topping. The salted caramel creates a rich, buttery contrast that elevates the pie to next-level indulgence.
White Chocolate Peanut Butter
Swap the semi-sweet chocolate chips for 2 cups white chocolate chips, melted and swirled into the peanut butter layer. The creamy white chocolate pairs perfectly with the peanut butter, creating a lighter, dreamier texture.
For extra richness, fold ½ cup of whipped cream into the melted white chocolate before swirling. This variation is especially popular during spring and summer gatherings.
Cookie Dough Bites
Add ½ cup of cookie dough chunks (homemade or store-bought) to the peanut butter filling before baking. The dough pockets create delightful surprises in every bite. I like to use Ben & Jerry’s cookie dough ice cream mix for this—it’s pre-measured and foolproof.
For a showstopper presentation, press additional cookie dough onto the pie’s edges after baking and bake for 5-7 minutes at 350°F to set.
Espresso Infusion
Boost the peanut butter filling with 1 tablespoon of instant espresso powder dissolved in the ½ cup milk. The espresso enhances the peanut butter’s nuttiness and balances the sweetness, creating a sophisticated flavor profile.
This works especially well with a dark chocolate swirl. For an extra coffee kick, sprinkle crushed espresso beans on top before serving.
Nutty Crunch Layer
Press ½ cup chopped roasted peanuts into the bottom of the pie crust before adding the filling. The peanuts add a delightful crunch that complements the creamy peanut butter. For variety, mix in ¼ cup chopped pecans or almonds.
Toast the nuts in a dry pan for 3-4 minutes until fragrant, then sprinkle them evenly across the crust’s base before pouring in the filling.

Frequently asked questions
Can I make this pie without a food processor for the crust?
If you don't have a food processor, crush the Oreos in a sturdy plastic bag using a rolling pin or heavy pan. For extra fine crumbs, pulse them in a blender or even grind them in a coffee grinder. The key is to get the cookies as fine as possible to prevent a gritty texture in your crust.
How do I prevent cracks in the filling while baking?
Cracks happen when the pie bakes too quickly. To avoid this, bake at 350°F for the full 45-50 minutes without opening the oven door. Let the pie cool completely in the pan for at least 2 hours before refrigerating. Also, make sure your filling is at room temperature before pouring it into the crust.
Can I use a different type of peanut butter?
While the recipe calls for creamy natural peanut butter, you can substitute with regular creamy peanut butter if that's what you have. Avoid chunky peanut butter as it won't blend as smoothly. For extra richness, consider adding 1 tablespoon of melted butter to the peanut butter mixture to enhance the fudgy texture.
How far ahead can I prepare this pie?
This pie tastes even better the next day! You can assemble it completely up to 24 hours ahead and refrigerate it. For longer storage, cover tightly and refrigerate for up to 5 days. The flavors meld beautifully over time, making it perfect for make-ahead desserts. Just let it sit at room temperature for 30 minutes before serving.
What's the best way to slice this pie for clean edges?
Use a warm, sharp knife for clean slices. Dip the knife in hot water, wipe it dry, and slice through the pie. This prevents the filling from sticking to the knife. For extra presentation, chill the pie for 1 hour before slicing to firm up the filling slightly. Serve each slice with a dollop of whipped cream for that restaurant-quality touch!
