Ingredients You’ll Need

One of the best things about this recipe is that every ingredient truly counts. These humble building blocks come together to create stunning layers of flavor and texture, making the Giant Reese’s Peanut Butter Cup Pie pure magic with just a handful of essentials.

Graham cracker crumbs: These create a sweet, buttery crust that mimics the classic candy shell and gives the pie its structure.
Granulated sugar: A touch of sweetness brightens up the crust and balances the rich peanut butter filling.
Unsalted butter, melted: Butter binds the crust together and gives it just the right amount of richness.
Creamy peanut butter: The absolute star here—choose your favorite brand for the creamiest, dreamiest base.
Powdered sugar: This adds sweetness and also helps make the peanut butter filling fluffy and smooth.
Heavy cream: Whipped to soft peaks, it creates airy silkiness that lightens the decadent filling.
Vanilla extract: A teaspoon lifts up and rounds out all the flavors beautifully.
Chopped Reese’s Peanut Butter Cups (filling): Stirred into the mousse, these chocolatey nuggets add texture and bursts of candy joy.
Creamy peanut butter (drizzle): Warm and pourable, this ties the whole pie together in true Reese’s style.
Chopped Reese’s Peanut Butter Cups (garnish): Extra candy on top turns every slice into a masterpiece and lets everyone know what they’re about to dig into.

How to Make Giant Reese’s Peanut Butter Cup Pie

Step 1: Build the Crust

Start by prepping a 9-inch pie pan—no need to grease it since the buttery base does all the work! Mix the graham cracker crumbs, sugar, and melted butter together until they resemble damp sand. Press this delicious mixture firmly into the bottom and sides of your pan. Take your time here and really compact the crust so it holds together, then pop it in the fridge while you work on the filling.

Step 2: Whip Up the Peanut Butter Filling

In a large bowl, beat together the creamy peanut butter and powdered sugar until totally smooth. This base will be dense and rich, the perfect match for the lightness coming next. Make sure every bit of powdered sugar is mixed in for a glossy, lump-free texture.

Step 3: Make the Whipped Cream

Grab another bowl and pour in the heavy cream and vanilla extract. Whip these together until you get stiff peaks—the whipped cream should hold its shape when you lift the beaters. This step is what takes the filling from heavy to heavenly, so don’t be tempted to skip it.

Step 4: Fold and Mix

Now, gently fold the whipped cream into the peanut butter mixture in batches. Use a soft hand to keep things light and airy! Stir just until combined to maintain that lovely mousse-like texture. Then, sprinkle in half a cup of chopped Reese’s Peanut Butter Cups and fold until evenly distributed.

Step 5: Assemble and Chill

Pour the lush filling into your prepared crust and use a spatula to smooth the top. It’s a generous mound, so pile it high and make sure it’s even. Transfer to the refrigerator and chill for at least four hours—overnight if you can wait! This step is key so the Giant Reese’s Peanut Butter Cup Pie slices beautifully.

Step 6: Finish with Drizzle and Candy

Just before serving, melt the extra peanut butter (a few seconds in the microwave does the trick) so it’s silky enough to drizzle. Zigzag it over the entire pie, then cover with the remaining chopped Reese’s. Each slice should look as irresistible as it tastes!

How to Serve Giant Reese’s Peanut Butter Cup Pie

Garnishes

Top each slice with even more chopped Reese’s cups, a dollop of whipped cream, or a sprinkle of sea salt if you like a salty-sweet kick. The shiny peanut butter drizzle not only adds creamy flavor but also makes the pie look extra tempting. A drizzle of chocolate syrup or ganache can take the wow factor up another notch!

Side Dishes

This pie is rich, so serving it alongside something simple is perfect—a scoop of vanilla ice cream, a glass of cold milk, or even fresh berries for a pop of color and tartness. Coffee or hot chocolate also pairs beautifully with the decadent flavors of the Giant Reese’s Peanut Butter Cup Pie.

Creative Ways to Present

For a playful twist, serve mini slices on cupcake liners at a party, or arrange slices on a platter interspersed with whole Reese’s cups as decoration. For holidays, top with colored sprinkles, or use themed candy for a festive look. However you serve it, this pie invites plenty of oohs and aahs.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, cover the pie tightly with plastic wrap or transfer slices to an airtight container. It will stay fresh (and delicious!) in the refrigerator for up to five days, though chances are it’ll disappear much sooner.

Freezing

The Giant Reese’s Peanut Butter Cup Pie actually freezes beautifully! Freeze the pie (or individual slices) uncovered until firm, then wrap in plastic and foil. It will keep for up to two months. When you’re ready to indulge, defrost overnight in the fridge before serving.

Reheating

This pie is best enjoyed cold or at room temperature, so reheating isn’t needed. If you prefer a softer filling, leave a slice out at room temperature for 15 minutes. If you want the drizzle extra gooey, just warm it slightly before eating.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! If you love a bit of crunch, swap in crunchy peanut butter. Your Giant Reese’s Peanut Butter Cup Pie will have a more textured filling that’s just as satisfying.

Do I have to use Reese’s brand cups?

While traditional Reese’s give you maximum nostalgia, feel free to use any chocolate peanut butter cup you love—just chop them up and mix them in as directed.

Can I make this pie gluten free?

Yes! Substitute gluten-free graham crackers (and verify your candy is safe) for a pie that’s fully gluten free but just as decadent.

How far in advance can I make this pie?

Giant Reese’s Peanut Butter Cup Pie can be made up to 2 days ahead. Store it covered in the refrigerator, and wait to add the drizzle and extra candy until just before serving for the best presentation.

What’s the best way to slice the pie without making a mess?

Use a large, sharp knife dipped in hot water and wiped dry between cuts—this helps you get perfect, clean slices every time, showing off all the layers of your masterpiece.
