I can’t resist a Reese’s cup, and this Giant Reese’s Peanut Butter Cup Pie is basically my candy-aisle daydream turned into a sliceable dessert. Imagine a thick Oreo cookie crust, piled high with fluffy peanut butter cheesecake filling, finished with a glossy chocolate layer and an avalanche of Reese’s candies on top.

This pie looks like it came straight from a bakery window, but it’s secretly simple and completely no-bake. It’s the kind of over-the-top dessert I bring to parties when I want people to stop mid-conversation and say, “Wait… what is that?” If you’re a chocolate and peanut butter lover, this one’s going to live in your regular dessert rotation.

What Makes This Giant Reese’s Peanut Butter Cup Pie So Special?

When I first tested this pie, my goal was to make it taste like a supersized Reese’s cup, but creamier and more decadent. The filling is a cross between a mousse and a cheesecake—silky from cream cheese, airy from whipped cream, and rich with real peanut butter.

The Oreo crust gives you that deep, dark chocolate base that doesn’t turn soggy, even after a night in the fridge. A soft ganache layer mimics the chocolate shell of a Reese’s cup, and the mountain of candy on top adds crunch, color, and a lot of fun. Every bite is creamy, crunchy, salty, and sweet all at once.

Ingredients for the Giant Reese’s Peanut Butter Cup Pie

I love that this pie uses pantry-friendly ingredients with big payoff. Here’s what each one is doing for you:

Oreo cookies – Crushed cookies create that classic chocolate cookie crust that tastes like the outside of a candy bar.
Unsalted butter – Binds the cookie crumbs so the crust holds together when sliced.
Fine sea salt – Just a pinch wakes up all the chocolate and peanut butter flavors.
Cream cheese – The base of the filling; it adds body and a slight tang that keeps the pie from being too sweet.
Creamy peanut butter – The star flavor; gives the filling its nutty richness and that unmistakable Reese’s vibe.
Powdered sugar – Sweetens the filling while keeping it smooth and lump-free.
Vanilla extract – Adds warmth and depth so the chocolate and peanut butter taste more rounded.
Heavy whipping cream – Whipped and folded in to make the filling light, fluffy, and mousse-like.
Mini Reese’s peanut butter cups – Nestled inside the filling for pockets of candy in every slice.
Semi-sweet chocolate chips – Melted into ganache to create a soft, sliceable chocolate layer on top.
More heavy cream (for ganache) – Turns the chocolate chips into a glossy, pourable topping that sets beautifully.
Light corn syrup (optional) – Helps the ganache set with extra shine and softness.
Assorted Reese’s candies – Mini cups, Reese’s Pieces, and chopped bars make the top look like a candy-shop explosion.
Extra creamy peanut butter – Warmed and drizzled over the top for a dramatic finishing touch.
Additional heavy cream and powdered sugar – Whipped into soft peaks for those fluffy swirls around the edge.

How To Make the Giant Reese’s Peanut Butter Cup Pie

Step 1: Build the Oreo crust

Crush the Oreo cookies into fine crumbs, then mix them with melted butter and a pinch of salt until the texture resembles wet sand. Press the mixture firmly into the bottom and slightly up the sides of a 9-inch springform pan. I like to use the bottom of a measuring cup to really compact the crust so it slices cleanly. Chill the crust while you prepare the filling.

Step 2: Whip up the peanut butter cheesecake filling

Beat the softened cream cheese, peanut butter, powdered sugar, vanilla, and salt together until completely smooth and fluffy. In a separate chilled bowl, whip the heavy cream with a little powdered sugar until stiff peaks form. Gently fold the whipped cream into the peanut butter mixture in two additions, keeping as much air in the mixture as you can so the filling stays light.

Step 3: Layer the filling with hidden Reese’s cups

Spread about half of the peanut butter filling over the chilled crust and smooth the top. Sprinkle chopped mini Reese’s cups evenly over this layer, then spoon the remaining filling on top and smooth it out again. Cover the pan and chill for at least 4 hours, or until the filling feels set around the edges.

Step 4: Make the silky chocolate ganache

To mimic the chocolate shell of a Reese’s cup, heat heavy cream just until steaming, then pour it over a bowl of semi-sweet chocolate chips. Let it sit for a minute, then stir until the chocolate melts and the mixture turns silky and smooth. Stir in a splash of vanilla and a spoonful of corn syrup if you’d like extra shine. Let the ganache cool until it thickens slightly but is still pourable.

Step 5: Cover the pie in chocolate

Pour the cooled ganache over the chilled peanut butter filling, gently tipping the pan from side to side to help it flow to the edges. You can nudge it with an offset spatula if needed, but try not to disturb the filling underneath. Return the pie to the fridge so the ganache can set.

Step 6: Pile on whipped cream and candy

Whip additional heavy cream with powdered sugar until soft but stable peaks form. Pipe or spoon swirls of whipped cream around the edge of the pie. Top with whole and halved mini Reese’s, Reese’s Pieces, and chopped peanut butter bars, pressing them gently into the whipped cream and ganache.

Step 7: Finish with a peanut butter drizzle

Warm a little extra peanut butter until just fluid—about 15 to 20 seconds in the microwave—and drizzle it generously over the candy-topped pie. Chill the assembled pie for at least 2 more hours, or until it’s very firm. When you’re ready to serve, run a hot knife around the edge of the pan, release the springform, and slice into that glorious giant Reese’s-inspired pie.

Serving and Storing This Giant Reese’s Peanut Butter Cup Pie

Because this pie is so rich, I usually cut it into 10 to 12 slim wedges. A small slice goes a long way, especially if you’re serving it after a big meal. For the cleanest presentation, dip a sharp knife in hot water and wipe it dry between each cut so you glide through the ganache and filling.

Leftovers need to stay chilled. Cover the pie tightly and store it in the refrigerator for up to 4 days—the crust stays surprisingly crisp and the filling actually slices even better on day two. If you want to make it further in advance, you can freeze the pie (without the whipped cream and candy topping) for up to 1 month. Thaw in the fridge overnight, then decorate just before serving.

What to Serve With Giant Reese’s Peanut Butter Cup Pie

Vanilla ice cream or gelato

A scoop of vanilla on the side cools down all that chocolate and peanut butter richness and adds a creamy contrast.

Hot coffee or espresso

I love pairing a small slice of this pie with a strong cup of coffee or a shot of espresso—the bitterness balances the sweetness perfectly.

Salted roasted peanuts

A little bowl of roasted, lightly salted peanuts on the table echoes the flavor of the pie and adds an extra crunchy, savory bite.

Fresh berries

Strawberries, raspberries, or even sliced bananas soften the intensity of the pie and give you a pop of freshness on the plate.

Whipped cream clouds

If you’re serving a crowd, offer extra whipped cream on the side so people can dollop more on their slices.

Tall glasses of cold milk

For kids (and kids at heart), an icy glass of milk is the most nostalgic, cookie-shop-style pairing.

Simple savory snacks

If this pie is part of a game-day or movie-night spread, I like to put out salty snacks like pretzels or popcorn to balance things out.
