Desserts
This peanut butter pie with Reese's peanut butter cups delivers the ultimate dessert experience—rich, creamy peanut butter swirls paired with fudgy, melty Reese's pieces in every bite.
After testing countless variations, I've perfected a recipe that balances texture and flavor without being overly sweet or greasy, making it a crowd-pleaser for any occasion. The secret lies in the precise ratio of peanut butter to eggs and the strategic placement of Reese's cups during baking.
The filling starts with a smooth peanut butter base, enhanced by powdered sugar and a touch of vanilla for depth, while the crust provides a sturdy foundation that holds up to the creamy filling.
What sets this pie apart is the way the Reese's cups melt slightly during baking, creating pockets of chocolatey peanut butter goodness that contrast beautifully with the velvety swirls. Baking at 350°F ensures a perfectly set yet tender texture.
By the time you slice into this pie, you'll be rewarded with a dessert that's equal parts indulgent and impressive—creamy peanut butter filling swirled with melted Reese's pieces, all topped with a dusting of powdered sugar for a professional finish.
The contrast of textures and flavors makes it impossible to eat just one slice, and the recipe scales easily for gatherings or special occasions.
Serve it chilled with a dollop of whipped cream or a drizzle of melted chocolate for extra decadence. This pie is the perfect way to satisfy peanut butter lovers and chocolate enthusiasts alike, proving that homemade can truly be better than store-bought. Let's get baking!
Ingredients for peanut butter pie with reese's peanut butter cups
Twelve ingredients. One showstopping pie. Creamy, crunchy, and impossible to resist.
| Ingredient | Amount | Notes |
|---|---|---|
| Reese's Peanut Butter Cups 🍫 | 12 whole | Unwrapped, chopped into chunks |
| Creamy Peanut Butter 🥜 | 2 cups | Natural, unsweetened preferred |
| Powdered Sugar 🍚 | 1 ½ cups | Confectioners' sugar, sifted |
| Large Eggs 🥚 | 4 whole | Room temperature, beaten |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for crust |
| All-Purpose Flour 🌾 | 1 cup | For pie crust base |
| Granulated Sugar 🍬 | ¼ cup | For crust sweetness |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Heavy Cream 🥛 | ½ cup | Chilled, for swirls |
| Dark Chocolate Chips 🍫 | ¼ cup | Optional, for extra crunch |
| Whipped Cream 🍦 | ½ cup | For serving (optional) |
| Milk 💧 | 1 tbsp | For crust consistency |
Reese's cups are the star here—grab the family-size bag for the best value. The peanut butter? Natural, unsweetened gives the best flavor without overpowering. I always use Jif Natural or Smucker's for that rich, smooth texture. For the crust, butter should be cold—cut it into tiny cubes so it distributes evenly. The powdered sugar is non-negotiable—Duncan Hines or Domino work perfectly, but sift it to avoid lumps. Pro tip: Toast your flour in the oven for 5 minutes before mixing to deepen the crust flavor.
No Reese's cups? Use 12 chocolate-covered peanut butter balls—same effect. Ran out of heavy cream? Whipped topping works too, though it won't be as rich. The vanilla extract matters—pure Madagascar is ideal, but imitation is fine if that's what you've got. For the crust, if you're short on butter, substitute shortening (but it won't taste as good). The dark chocolate chips? Ghirardelli or Nestlé Toll House are my go-tos—they melt beautifully and add that extra crunch. If you're feeling fancy, add a sprinkle of flaky sea salt on top before baking for a gourmet touch.
This pie needs time to set—at least 4 hours in the fridge before slicing. The filling keeps for 5 days covered, but trust me, it won't last that long. For make-ahead magic, bake the crust a day ahead and store it wrapped at room temp. The filling can be made 2 days ahead and refrigerated. Serve with whipped cream? Homemade is best, but store-bought in a can works in a pinch. Freeze individual slices for up to 2 months—just thaw at room temp before serving.
Why You'll Love This Recipe

- Party in a Pie: This is my secret weapon for birthdays, potlucks, or when I just want to impress without slaving away. The crust (if you use one) is optional, so it’s equally great for a quick weeknight treat or a showstopper dessert. (Yes, even on a Tuesday night.)

Step-by-step instructions for peanut butter pie with Reese's peanut butter cups
Here's how to build the perfect peanut butter pie—rich, creamy filling with Reese's chunks for that signature crunch.
Prepare the Crust
In a large bowl, combine the 0.5 cup unsalted butter, 0.25 cup granulated sugar, 1 cup all-purpose flour, 0.5 tsp salt, and 1 tbsp milk. Use a pastry cutter or your fingers to work the butter into the flour mixture until it resembles coarse crumbs with pea-sized butter pieces.
Press this mixture evenly into a 9-inch pie dish, creating a 1-inch thick crust. Chill in the refrigerator for 30 minutes while you prepare the filling. This chilling step prevents shrinking during baking and ensures a sturdy base. I like to use the back of a measuring cup to press it down firmly and evenly.
Mix the Filling
In a medium saucepan, combine the 2 cups creamy peanut butter, 1.5 cups powdered sugar, 4 whole large eggs, and 2 tsp vanilla extract. Cook over medium heat, stirring constantly with a wooden spoon, until the mixture reaches 160°F on an instant-read thermometer and thickens to a pudding-like consistency.
Remove from heat immediately to prevent curdling. Stir in the 12 whole Reese's peanut butter cups that you've chopped into chunks - you want them evenly distributed throughout the filling. This is where the magic happens—the Reese's add that signature crunch while keeping the filling creamy.
Add the Cream Swirls
In a separate bowl, whip the 0.5 cup heavy cream until soft peaks form. Carefully fold this whipped cream into the peanut butter mixture using a spatula, creating gentle swirls. Don't overmix—just enough to create those beautiful marbled patterns when poured into the crust.
Pour the filling into the chilled pie crust, spreading it evenly. If you're using the 0.25 cup dark chocolate chips, sprinkle them over the top before baking. This creates pockets of chocolatey goodness throughout each slice.
Bake to Golden Perfection
Preheat your oven to 350°F. Bake the pie for 50-55 minutes until the center is just set (it should still have a slight wobble when gently shaken). The edges should be golden brown, and the filling should be completely set but still slightly jiggly in the center.
I know it's tempting to check early, but resist! The pie needs that full baking time to develop proper texture. If the crust starts browning too quickly, tent it loosely with aluminum foil to prevent over-browning while the center sets.
Chill and Serve
Remove the pie from the oven and let it cool completely on a wire rack. Then refrigerate for at least 4 hours (overnight is even better). This chilling time allows the flavors to meld and the texture to firm up just right.
Before serving, top with the 0.5 cup whipped cream if desired. The contrast of cool whipped cream against the warm peanut butter filling is pure decadence. Cut into wedges and serve immediately—every bite delivers that perfect balance of creamy peanut butter and crunchy Reese's pieces.
Pro Tips For Making Peanut Butter Pie With Reese'S Peanut Butter Cups
- Chill the Crust: Pop the crust into the freezer for 15 minutes before adding the filling—this prevents a soggy bottom when the warm peanut butter mixture hits it. I learned this the hard way after a pie that looked perfect but tasted like a puddle.
- Melt Reese’s Gently: Use a double boiler or microwave in 20-second bursts to melt the Reese’s cups, stirring between each. Overheating turns the chocolate grainy, and you’ll end up with a filling that tastes like candy-coated grit instead of smooth decadence.
- Whisk Eggs Until Ribbon Stage: Beat the eggs and peanut butter until they hold a slow ribbon when the whisk is lifted—about 3-4 minutes. Under-whisked eggs make the pie dense, and over-whisked ones can turn it rubbery. (Yes, even if you’re impatient like me.)
- Sift the Powdered Sugar: Sift the powdered sugar into the filling last, then fold it in gently with a spatula. Skipping this creates lumps, and no one wants to bite into a surprise sugar clump in their Reese’s heaven.
Pro cooking tips for great peanut butter pie with reese's peanut butter cups
Peanut Butter Temp Control
Peanut butter filling has a tendency to curdle if overheated, so use a candy thermometer to monitor the temperature precisely. Heat the mixture over medium-low heat and remove it from the heat as soon as it hits 160°F—any hotter risks scrambling the eggs.
I use a Thermoworks Thermapen for accuracy, and it’s changed how I bake custard-based desserts forever. 🌡️
Reese's Placement Trick
For maximum crunch and melt, fold the chopped Reese's cups into the filling after removing it from heat. This prevents them from dissolving completely and ensures each bite has that signature texture contrast.
I like to chop them into ½-inch chunks for even distribution—no need to overdo it, just 12 cups total. 🍫
Crust Pre-Baking Hack
Prevent a soggy crust by blind-baking it for 10 minutes at 350°F before adding the filling. Line the crust with parchment paper, fill with pie weights or dried beans, and bake until lightly golden.
This step creates a barrier that keeps the crust crispy even after the creamy filling sets. I always use Wilton pie weights for perfect results. 🥧
Swirl Technique Mastery
The key to those gorgeous marbled swirls is patience and a light hand. Use a spatula to gently fold the whipped cream into the peanut butter mixture in three stages—don’t overmix or the swirls will disappear.
Pour the filling into the crust in three sections, then use the back of a spoon to create gentle, wavy patterns. This method ensures visual appeal and even texture. ✨
Oven Rack Placement
Place your pie on the middle rack of the oven for even baking. The middle rack ensures the crust bakes evenly without burning at the bottom. If your oven runs hot, consider lowering the temperature to 325°F and adding 5-10 minutes to the bake time.
I always rotate the pie halfway through for uniform golden browning. 🔥
Chilling Like a Pro
For the best texture, chill the pie for at least 4 hours—overnight is ideal. This allows the filling to set properly and develop its signature creamy yet firm consistency.
I like to place the pie on a wire rack in the fridge to prevent condensation from forming on the bottom crust. Trust me, the wait is worth every bite. ❄️

Frequently asked questions
Can I make this peanut butter pie without Reese's cups?
While Reese's cups add that signature crunch and melt, you can substitute with 12 chocolate-covered peanut butter balls or even ½ cup crushed chocolate sandwich cookies for a similar effect. For a nut-free version, try chocolate chips or chopped dark chocolate—just reduce the amount slightly since they won't melt as dramatically. The filling will still taste amazing!
Why does my peanut butter pie filling look grainy?
Graininess usually happens when the peanut butter isn't smooth enough or the eggs curdle from overheating. Always use creamy peanut butter (not chunky) and heat the mixture gently over medium-low heat until it reaches 160°F. Remove it from heat immediately to prevent scrambling. If it's still grainy, whisk in 1 tablespoon of milk to smooth it out.
How do I prevent the crust from getting soggy?
Prevent a soggy crust by blind-baking it for 10 minutes at 350°F before adding the filling. Line the crust with parchment paper, fill with pie weights or dried beans, and bake until lightly golden. This creates a barrier that keeps the crust crispy. Another trick? Chill the pie for at least 4 hours before slicing to let the filling set properly.
Can I make this pie ahead of time?
Yes! This pie actually tastes better the next day. You can assemble it 2 days ahead—just refrigerate the filling separately and bake the crust a day in advance. Combine them right before baking, then chill again after cooling. For serving, let it sit at room temperature for 30 minutes before slicing for cleaner cuts. Perfect for meal prep!
What's the best way to store leftovers?
Store leftovers in an airtight container in the fridge for up to 5 days. For longer storage, freeze individual slices (wrapped tightly) for up to 2 months. Thaw at room temperature before serving. Pro tip: Freeze the whole pie (uncut) for 1 month325°F for 15 minutes.
