This no-bake Reese's peanut butter pie delivers all the indulgence of your favorite candy bar in every creamy, crunchy bite—without a single minute in the oven.
The secret lies in a fudgy, no-bake chocolate layer that sets perfectly in the fridge, topped with a velvety peanut butter filling and crowned with crispy oat clusters that mimic Reese's crunch.
I developed this recipe after years of testing, ensuring each component holds its texture while blending into a cohesive dessert that's foolproof and restaurant-worthy.
The beauty of this pie is in its simplicity: no baking, no special equipment, just layers that come together in minutes. A graham cracker crust provides sturdy support, while the peanut butter filling stays rich and smooth thanks to a precise ratio of powdered sugar and cream cheese.
The oat crowns toast just enough to add texture without overpowering the creamy base—a technique I perfected after three failed attempts with burnt oats.
What you'll end up with is a slice that balances crunchy, creamy, and fudgy perfectly—each bite delivers that nostalgic Reese's flavor with none of the mess.
The pie sets firm enough to slice cleanly but still melts in your mouth, making it ideal for potlucks, holidays, or satisfying a sudden chocolate craving. No one will guess it took less than 30 minutes of active prep time.
Serve chilled with a dollop of whipped cream or a sprinkle of chocolate shavings for extra indulgence. This pie keeps beautifully in the fridge for up to 5 days, making it perfect for meal prep or last-minute dessert solutions. Let's get started on this crowd-pleaser!
Ingredients for no bake reese's peanut butter pie
Pantry staples plus three key ingredients that nail Reese's flavor—crunchy oats, creamy peanut butter, and rich chocolate.
| Ingredient | Amount | Notes |
|---|---|---|
| Graham Cracker Crumbs 🍪 | 2 ½ cups | Crushed finely for sturdy base |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat for richness |
| Powdered Sugar 🍚 | 1 cup | Confectioners' sugar preferred |
| Dark Chocolate Chips 🍫 | 1 ½ cups | Semi-sweet, 60% cocoa |
| Heavy Whipping Cream 🥛 | 1 cup | Cold for best texture |
| Cream Cheese 🧀 | 8 oz | Full-fat, softened |
| Peanut Butter 🥜 | 1 ½ cups | Creamy, unsweetened |
| Powdered Sugar 🍚 | 1 ½ cups | Extra for peanut butter layer |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality |
| Old-Fashioned Rolled Oats 🌾 | 2 cups | Quick or old-fashioned |
| Light Brown Sugar 🍚 | ½ cup | Packed, for oat crowns |
| Unsalted Butter 🧈 | ¼ cup | Melted, for oats |
| Salt 🧂 | ¼ tsp | Fine sea salt |
| Miniature Marshmallows 🍬 | 1 cup | For optional extra fluff |
| Chocolate Shavings 🍫 | ¼ cup | For garnish, optional |
The graham crackers set the foundation—Honey Maid or Nabisco work best, but any sturdy graham will do. The chocolate chips? Ghirardelli or Guittard semi-sweet (60% cocoa) melt perfectly without graininess. For the peanut butter, Jif or Skippy creamy gives the best consistency, but if you're feeling fancy, natural peanut butter with a splash of oilPhiladelphia full-fat stays smoothest when chilled. Grab a block instead of tubs for better texture. And those oats? Bob's Red Mill rolled oats toast just right—no gummy bits.
No graham crackers? Crushed digestive biscuits or vanilla wafers work in a pinch (though they won't be as sturdy). Out of dark chocolate chips? Melted chocolate bars with 60% cocoa gets you close—just make sure they're fully melted and smooth. The peanut butter layer too thick? Add 1-2 tbsp heavy cream to loosen it up. For the oat crowns, quick oats work too, but they'll be slightly softer. Want extra fluff? Fold in mini marshmallows before toasting. And if you're short on vanilla, 1 tsp vanilla bean paste adds depth without extra moisture.
This pie needs at least 4 hours in the fridge to set properly—overnight is ideal. Store in an airtight container with parchment between layers to prevent sticking. Keeps for 5 days in the fridge, or 2 months frozen (wrap tightly!). The oat crowns stay crisp for about 3 days at room temp if stored in a sealed container. For make-ahead magic, assemble the whole pie a day ahead—flavors meld beautifully.

Step-by-step instructions for no-bake Reese's peanut butter pie
Here's how to assemble this decadent dessert with rich layers and crunchy oat crowns.
Prepare the Graham Cracker Crust
In a medium bowl, combine the 2.5 cups graham cracker crumbs with the 0.5 cup melted unsalted butter. Mix with a fork until the crumbs are evenly moistened and the mixture holds together when pressed. Press this mixture firmly into the bottom of a 9-inch pie dish, using the back of a spoon or a glass to create an even layer.
I like to pack it down gently but not too hard—you want it sturdy enough to hold the filling but still crumbly. Chill in the refrigerator while you prepare the chocolate layer. This step ensures your crust stays intact even with the heavy peanut butter filling later.
Make the Chocolate Layer
In a microwave-safe bowl, melt the 1.5 cups dark chocolate chips in 30-second intervals, stirring between each interval until completely smooth. Let it cool slightly for 2 minutes—it should be warm but not hot to the touch.
In a separate large bowl, beat the 8 oz cream cheese and 1 cup heavy whipping cream together until smooth and creamy. Add the melted chocolate and mix until fully combined. Fold in 1 cup powdered sugar and 1 tbsp vanilla extract until smooth. This layer needs to be perfectly blended to avoid any graininess in your pie.
Assemble the Peanut Butter Layer
In a separate bowl, beat the 1.5 cups peanut butter and 1.5 cups powdered sugar together until completely smooth. Add the 1 tbsp vanilla extract and mix well. Spread this peanut butter mixture evenly over the chilled chocolate layer in the pie dish.
Here's the thing—don't rush this step. Use a spatula to create an even layer, about ¼-inch thick. The peanut butter should cover the chocolate completely without any gaps. Place the pie back in the refrigerator to set while you prepare the oat crown.
Prepare the Oat Crown
In a small saucepan, combine the 2 cups old-fashioned rolled oats, 0.5 cup light brown sugar, 0.25 cup melted unsalted butter, and 0.25 tsp salt. Cook over medium-low heat, stirring constantly for 5-7 minutes until the mixture turns golden brown and fragrant.
Remove from heat and stir in the 1 cup miniature marshmallows until they're completely melted and the mixture is smooth. Immediately spoon this oat mixture around the edge of the pie dish, creating a thick border about 1-inch wide. Press it gently to create a textured crown that will contrast beautifully with the smooth filling.
Chill and Garnish
Refrigerate the pie for at least 4 hours or overnight to allow all layers to set completely. This chilling time is crucial—it lets the flavors meld and the textures develop properly.
Before serving, sprinkle the top with the 0.25 cup chocolate shavings for an elegant finish. Cut into slices and enjoy this no-bake dessert that combines all the classic Reese's flavors in one perfect pie! The contrast between the crunchy oat crown, creamy peanut butter, and rich chocolate layers makes every bite irresistible.
Pro Tips For Making No Bake Reese'S Peanut Butter Pie
- CHILL THE CREAM: Mix your heavy whipping cream and powdered sugar right in the fridge—not on the counter. I used to rush this step and end up with a sad, grainy filling that never stiffened up. Cold tools matter more than you’d think, especially when you’re impatient to eat it.
- MELT THE BUTTER FIRST: Heat the butter for the crust just until it’s liquid (about 30 seconds in the microwave), then mix it into the graham cracker crumbs. Cold butter creates dry, crumbly pockets—this ensures a smooth, pressable base that won’t crumble when you slice it. (Yes, even if you’re in a hurry.)
- DON’T OVERMIX THE FILLING: Once you fold in the Reese’s pieces, stop stirring after one turn. Overmixing melts the chocolate unevenly, turning your filling into a sticky mess instead of a creamy, chunky dream. Think "just combined," not "fully incorporated."
- PRESS THE CRUST HARD: Pack the graham cracker crust into the pan firmly—use the bottom of a measuring cup or your palm to press it down. A loose crust soaks up filling and falls apart when you cut it. (I learned this after my first pie collapsed like a house of cards.)
Flavor customization for this recipe
Spicy Chocolate Kick
For a bold twist, fold ½ tsp cayenne pepper or 1 tsp chili powder into the peanut butter layer. This adds a subtle heat that balances the sweetness beautifully.
Pair with dulce de leche drizzle on top for a sweet-spicy contrast. I use Penzeys hot chocolate mix for extra depth—just a pinch makes all the difference. 🌶️
Salted Caramel Swirl
Take this pie to the next level by adding a ½ cup salted caramel sauce (like Trader Joe's) swirled into the peanut butter layer before chilling. The salty-sweet combo elevates the classic Reese's flavors.
For extra flair, sprinkle flaky sea salt on top of the chocolate shavings. I recommend Maldon sea salt for its delicate crunch.
White Chocolate Peanut Butter
Swap out the dark chocolate chips for 1.5 cups white chocolate chips (like Guittard) to create a sweeter, creamier base. The white chocolate pairs perfectly with peanut butter, giving the pie a lighter, almost marshmallow-like texture.
Add 1 tsp almond extract to the peanut butter layer for a nutty depth. This version feels like a Reese's dream come true. 🥛
Espresso Boost
For coffee lovers, stir 1 tbsp instant espresso powder into the melted chocolate layer. This adds a mocha-like richness that cuts through the sweetness. I use Starbucks Via instant espresso for consistent results.
The espresso enhances the chocolate flavor without overpowering the peanut butter. Perfect for a dessert with a sophisticated twist.
Nutty Crunch Layer
Add texture by pressing ½ cup chopped pecans or walnuts into the graham cracker crust before adding the chocolate layer. For extra crunch, toast the nuts in a dry pan for 3-5 minutes until fragrant.
The nuts add a buttery, toasty note that complements the peanut butter beautifully. I like to use pecans for their natural sweetness. 🌰
Citrus Zest Twist
Brighten up the pie by adding 1 tsp orange zest to the peanut butter layer. The citrus cuts through the richness and adds a refreshing note.
Pair with orange liqueur (Cointreau)—just 1 tbsp in the chocolate layer—for a boozy depth. The zest works especially well with the white chocolate variation. 🍊

Frequently asked questions
Can I make this pie without a graham cracker crust?
For a gluten-free option, use 1.5 cups crushed gluten-free graham crackers or 2 cups crushed digestive biscuits instead. If you want a cookie crust, try 1.5 cups crushed chocolate sandwich cookies like Oreos for extra richness. The key is using enough crumbs to create a sturdy base that can hold the heavy filling.
How do I prevent the peanut butter layer from getting too runny?
If your peanut butter mixture feels too thin, simply add 1-2 tablespoons of powdered sugar at a time until it reaches a spreadable but thick consistency. For extra stability, chill the peanut butter mixture for 10-15 minutes before spreading it over the chocolate layer. This helps it set more firmly in the fridge.
Can I use natural peanut butter in this recipe?
Yes, but you'll need to adjust the texture first. Natural peanut butter often contains oil, which can make the filling too thin. To fix this, add 1 tablespoon of heavy cream to loosen it up, or simply use 1.25 cups instead of 1.5 cups to compensate. The flavor will be just as rich, but the texture will be more stable.
What's the best way to store leftovers?
Store your pie in an airtight container with parchment paper between layers to prevent sticking. It keeps well in the fridge for 5 days and can be frozen for up to 2 months. For the oat crown, keep it in a sealed container at room temperature for up to 3 days—it stays crispy that way. Thaw frozen pies overnight in the fridge for best results.
Why did my oat crown turn out too soft?
This usually happens if the oats weren't toasted enough or if they absorbed too much moisture. Next time, cook the oat mixture over medium heat until it's golden brown and fragrant, then immediately stir in the marshmallows. If it still feels soft, try using quick oats instead of rolled oats—they toast faster and hold their shape better.
