This peanut butter pie with Reese's peanut butter cups delivers a nutty-creamy experience that rivals anything you'd find in a bakery. The secret lies in balancing a rich, velvety peanut butter filling with chunks of Reese's cups for that signature crunch—every bite is a perfect contrast of textures and flavors.
I've perfected this recipe over years of testing, ensuring the crust stays crisp while the filling remains silky smooth.
The foundation starts with a classic graham cracker crust, but the real magic happens in the filling. Creamy peanut butter, powdered sugar, and eggs blend into a luscious base, while chopped Reese's cups add bursts of chocolatey crunch.
Baking at 350°F for 45-50 minutes ensures the filling sets just right without drying out, creating that signature creamy texture we all love.
What makes this pie truly special is how it delivers on that creamy promise—no graininess, no separation, just pure peanut butter decadence. The Reese's cups melt slightly during baking, creating pockets of gooey chocolate that cut through the richness.
Serve it chilled with a dollop of whipped cream or a drizzle of melted chocolate for the ultimate dessert experience.
This recipe works for both classic and vegan adaptations—just swap the crust and dairy ingredients as needed. Whether you're baking for a crowd or treating yourself to a single slice, this pie delivers restaurant-quality results with minimal effort. Let's get baking!
Ingredients for peanut butter pie with reese's peanut butter cups
Graham crackers, peanut butter, and chocolate—just three things that turn into pure decadence.
| Ingredient | Amount | Notes |
|---|---|---|
| Graham Cracker Crumbs 🍪 | 2 cups | Finely crushed, no large pieces |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat for richness |
| Reese's Peanut Butter Cups 🍫 | 1 ½ cups | Chopped into 1/4-inch pieces |
| Creamy Peanut Butter 🥜 | 1 ½ cups | Natural, no added sugar |
| Powdered Sugar 🍚 | 1 ½ cups | Sifted for smooth filling |
| Large Eggs 🥚 | 4 whole | Room temperature for blending |
| Vanilla Extract 🌿 | 2 tsp | Pure, high-quality extract |
| Heavy Whipping Cream 🥛 | 1 cup | Whipped for topping (optional) |
| Salt 🧂 | ½ tsp | Fine sea salt for balance |
| Melted Chocolate 🍫 | ½ cup | Dark or semi-sweet, for drizzle |
| Granulated Sugar 🍚 | ¼ cup | For crust, if needed |
| Milk 🥛 | 2 tbsp | For crust consistency |
The Reese's cups are non-negotiable here. Grab the family-size bags from Target—they're cheaper and save time chopping. Look for the classic milk chocolate ones, not the peanut butter-filled variety (those melt differently). I always chop mine into 1/4-inch pieces so they melt just enough to create pockets of gooey chocolate without turning to mush. The peanut butter? Natural, no-stir brands like Smucker's or Jif work best—they're smoother and less likely to separate. If you're using powdered sugar, sift it first—this prevents grainy filling, trust me.
No Reese's cups? Chopped chocolate-covered peanuts or peanut butter M&M's work in a pinch, but the texture won't be the same. Short on powdered sugar? Use granulated sugar plus 1/8 tsp cornstarch to mimic the texture. The crust can be made ahead—just press it into your pie dish and freeze it for up to 1 week. For the filling, if you're worried about separation, whisk the eggs and peanut butter together first, then add the powdered sugar. The vanilla extract should be pure—Walmart's Great Value brand is a solid budget pick, but if you're splurging, go for Nielsen-Massey.
This pie tastes even better the next day—3-4 days in the fridge is ideal. For make-ahead baking, assemble the pie (without the whipped cream topping) and refrigerate for 4 hours before baking. The filling sets as it cools, so don't rush it. To serve, I like to drizzle melted chocolate over the whipped cream—use a fork to create that marbled effect. Store leftovers covered, and if you're freezing, wrap tightly in plastic for up to 3 months. The crust stays crisp, but the filling gets even creamier after chilling.

Step-by-step instructions for peanut butter pie with Reese's peanut butter cups
Here's how to create a rich, creamy peanut butter pie with layers of Reese's cups—every slice will be restaurant-quality.
Prepare the Crust with Graham Cracker Crumbs
Preheat your oven to 350°F and melt the 0.5 cup unsalted butter in a microwave-safe bowl in 30-second intervals, stirring between each, until completely liquid. In a separate bowl, mix the melted butter with the 2 cups graham cracker crumbs and 0.25 cup granulated sugar until evenly combined. The texture should resemble wet sand.
Press this mixture firmly into a 9-inch pie dish, using the back of a measuring cup to create an even, compact base. Bake for 10 minutes until the edges begin to turn golden. Let it cool completely before adding the filling—this prevents a soggy crust. I like to press down gently with a glass to ensure an even layer.
Mix the Peanut Butter Filling
In a large mixing bowl, combine the 1.5 cups creamy peanut butter, 1.5 cups powdered sugar, 4 whole large eggs, 2 tsp vanilla extract, and 0.5 tsp salt. Whisk vigorously for 3-4 minutes until the mixture is smooth, thick, and completely homogeneous. The batter should coat the back of a spoon and hold its shape when dropped.
Fold in the 1.5 cups chopped Reese's peanut butter cups using a spatula, ensuring even distribution throughout the filling. The chopped pieces should be about ¼-inch in size—this creates pockets of gooey peanut butter throughout each slice. If the mixture seems too thick, add 1 tablespoon milk at a time until it reaches a pudding-like consistency.
Assemble and Bake the Pie
Pour the peanut butter mixture into the cooled crust, spreading it evenly to the edges. Tap the pie dish gently on the counter to remove any air bubbles. Bake at 350°F for 40-45 minutes, or until the center is just set but still slightly wobbly—this ensures a creamy texture. A toothpick inserted should come out with a few moist crumbs, not wet batter.
Remove from the oven and let it cool completely at room temperature for at least 2 hours. This resting period allows the filling to fully set while maintaining its creamy texture. If you can't wait, refrigerate for 1 hour to speed up the process, but don't skip this step entirely—it's what makes the difference between a good pie and a great one.
Add the Chocolate Drizzle and Topping
While the pie cools, melt the 0.5 cup chocolate in a double boiler or microwave, stirring until smooth. Once the pie is fully set, drizzle the melted chocolate over the top in zigzag patterns. For extra indulgence, whip the 1 cup heavy whipping cream to soft peaks and spread it over the chocolate layer. This step is optional but adds a luxurious finish that everyone will love.
Chill the pie in the refrigerator for at least 4 hours, or overnight, before serving. The contrast between the creamy peanut butter filling, the crunchy crust, and the smooth chocolate topping creates the perfect balance of textures. Cut into wedges and enjoy the rich, nutty layers that make this pie unforgettable.
Pro Tips For Making Peanut Butter Pie With Reese'S Peanut Butter Cups
- MELT THE CRUBS: Chill your crust mixture for at least 30 minutes before pressing it into the pan—this keeps it from crumbling into a sad, greasy mess. I learned this the hard way after my first attempt turned into a peanut butter-flavored puddle.
- CHOP THE REESE’S: Roughly chop the Reese’s cups into uneven pieces before folding them into the filling—this gives every bite that signature gooey contrast instead of a few lucky chunks. (Yes, even if you’re impatient like me.)
- WHISK THE PEANUT BUTTER: Beat the creamy peanut butter with the eggs until it’s completely smooth—no streaks, no lumps—before mixing in the powdered sugar. After burning three batches with uneven texture, I finally realized this step isn’t optional.
- BAKE UNTIL JIGGLE-FREE: Pull the pie out of the oven when the center still looks slightly underdone—it’ll firm up as it cools. Overbaking turns the filling into a dry, crumbly disaster. (Your future self will thank you.)
Creative variations of peanut butter pie with reese's peanut butter cups
No-Bake Peanut Butter
Skip the oven entirely with a no-bake version using 16 oz cream cheese, 1 cup powdered sugar, and 1 cup creamy peanut butter. Whisk until smooth, then fold in 1 cup chopped Reese's cups and 1 tsp vanilla.
Press into a graham cracker crust and chill for 6 hours or overnight. Top with whipped cream and chocolate shavings for a cool, creamy dessert that requires zero baking. 🍫
Vegan Adaptation
Replace the graham cracker crust with a vegan shortbread crust made from 1.5 cups almond flour, 0.5 cup coconut oil, and 0.25 cup maple syrup.
For the filling, use 1.5 cups vegan peanut butter (like Justin's), 1.5 cups powdered sugar, 4 tbsp aquafaba (chilled whipped egg whites), and 2 tsp vanilla. Bake as directed—this version stays just as creamy! 🌱
Chocolate Swirl
Create a marbled effect by folding ½ cup melted chocolate into half the peanut butter mixture before spreading it into the crust. After baking, the chocolate will create beautiful swirls throughout the pie.
Use dark or milk chocolate for a richer flavor, or white chocolate for a sweeter twist. This variation adds visual appeal and extra chocolatey bursts in every bite. 🍫
Peanut Butter Cup Crust
Swap the graham cracker crust for a Reese's cup crust by blending 1.5 cups crushed graham crackers with 0.5 cup melted butter and 0.5 cup crushed Reese's cups. Press into the pie dish and bake for 12 minutes at 350°F until set.
The extra peanut butter flavor in the crust elevates the pie to a whole new level of indulgence. 🥜
Banana Peanut Butter
Add 1 ripe banana, mashed, to the filling mixture for a fruity twist. The banana adds natural sweetness and moisture, balancing the richness of the peanut butter. Fold it in gently after mixing the base ingredients to avoid overmixing.
This variation works especially well with the no-bake version, as the banana prevents the filling from setting too firmly. 🍌
Caramel Drizzle
For a salty-sweet contrast, drizzle ½ cup homemade caramel sauce over the pie before adding whipped cream. Use a fork to create a marbled effect, or simply spread it evenly for a glossy finish.
Store-bought caramel (like Smucker's) works in a pinch, but homemade caramel made with 1 cup sugar and ½ cup heavy cream adds depth. 🍯
