Ingredients You'll Need

Each component serves a purpose: the salty-sweet crust anchors the pie, the airy peanut butter mousse delivers that nostalgic flavor, and the glossy ganache seals in freshness while adding sophisticated depth. Buy the best peanut butter and chocolate you can—because these two ingredients carry the dessert.

For the Oreo Crust

Oreo cookies (regular, not Double Stuf) – 24 whole cookies, filling included. The cream filling acts as a built-in binding agent, so you need less butter. Gluten-free chocolate sandwich cookies work seamlessly if you need a GF dessert.
Unsalted butter – 5 Tbsp, melted. Using unsalted butter lets you control salt; you’ll add a pinch later for balance.
Fine sea salt – ⅛ tsp. A whisper of salt wakes up the chocolate and keeps the crust from tasting flat.

For the Peanut Butter Mousse

Creamy conventional peanut butter – 1 cup (250 g). Natural styles separate and can turn greasy; choose Jif, Skippy, or similar for stability.
Confectioners’ sugar – ¾ cup. It dissolves instantly and keeps the mousse smooth.
Cream cheese – 4 oz, softened. Just enough to tighten the filling without turning it into cheesecake.
Pure vanilla extract – 1 tsp. Bolsters peanut flavor the way salt boosts chocolate.
Heavy cream – 1¼ cups, cold. You’ll whip half into soft peaks for lightness and fold it in.

For the Chocolate Ganache

Bittersweet chocolate (60–70 %) – 6 oz, finely chopped. Chips are fine, but bars melt silkier.
Heavy cream – ⅔ cup. Warmed just to a bare simmer so it melts the chocolate without seizing.
Light corn syrup or honey – 1 Tbsp. Optional, but adds shine and prevents the ganache from cracking when sliced.
Unsalted butter – 1 Tbsp, diced cold. Enriches the ganache and helps it slice cleanly.

Optional Garnishes

Chopped peanut butter cups
Chocolate curls or shaved bittersweet bar
Roasted salted peanuts, roughly chopped
Flaky sea salt for a finishing crunch

How to Make Indulgent Chocolate Peanut Butter Pie No Bake

Blitz the crust

Place whole Oreos (filling and all) in a food processor and pulse until you have fine, even crumbs—about 30 seconds. Add the melted butter and salt; pulse again until the mixture looks like wet sand and holds together when pinched. (No processor? Seal cookies in a zip-top bag and roll with a pin; stir butter in by hand.)

Press and chill

Tip the crumbs into a 9-inch pie plate. Using the flat bottom of a measuring cup, press firmly and evenly across the base first, then up the sides until the crust is about ¼-inch thick. Slide the plate into the freezer for 10 minutes to firm while you mix the filling.

Whip the cream

In a chilled bowl, beat ⅔ cup of the heavy cream to soft peaks—when the whisk leaves faint trails but the peaks flop over. Refrigerate while you continue so it stays cold and airy for folding later.

Beat the peanut butter base

In a stand mixer (or with hand beaters) beat the peanut butter, softened cream cheese, confectioners’ sugar, vanilla, and a tiny pinch of salt on medium-high until the mixture lightens in color and looks whipped—about 2 minutes. Stop and scrape the bowl once.

Fold, don’t stir

Retrieve the whipped cream. With a balloon whisk or flexible spatula, fold one-third of the cream into the peanut butter mixture to loosen it. Once streaky, add the remaining cream and fold just until no white streaks remain. Over-mixing deflates the filling and can make it dense.

Fill and level

Spoon the mousse into the chilled crust. Hold the spatula at a low angle and sweep from the center outward to create a gentle dome. This prevents air pockets and gives the ganache a smooth canvas.

Make the ganache

Place chopped chocolate, corn syrup, and butter in a heat-proof bowl. Bring the remaining ⅔ cup cream to a gentle simmer (tiny bubbles at the edge). Pour hot cream over chocolate, let stand 1 minute, then whisk from the center outward until glossy. Cool 5 minutes until it’s the consistency of pourable yogurt.

Glaze and chill

Starting at the center, drizzle ganache over the pie until the surface is just covered; a small offset spatula helps nudge it to the edges without spilling over. Refrigerate at least 4 hours (overnight is better) to set the layers and develop flavor.

Expert Tips

Use a metal pie plate

Metal conducts cold faster than glass, shaving 30 minutes off chill time and producing cleaner slices.

Chill your bowl and whisk

Ten minutes in the freezer helps heavy cream whip faster and to a loftier volume.

Score ganache before it sets

After 20 minutes in the fridge, lightly mark 8 slices with a warm knife; this prevents the top from cracking when you cut clean portions later.

Dip knife in hot water

Wipe dry between cuts for bakery-sharp wedges that show off the layers.

Toast the peanuts

If garnishing, roast 5 minutes at 350 °F for deeper flavor and a crisp contrast to the silky filling.

Swap the crust in summer

Pretzel or nut-crumb crusts hold up better in humid weather because they contain less moisture than sandwich cookies.

Variations to Try

Banana lovers: layer thin banana coins over the crust before adding peanut butter mousse.
Crunch factor: fold ½ cup chopped honey-roasted peanuts into the mousse for texture.
Dark & sophisticated: substitute ¼ cup of the peanut butter with Nutella and use a hazelnut liqueur in the ganache.
Dairy-free: use coconut cream (chilled overnight) in place of heavy cream and vegan cream cheese; choose dairy-free chocolate cookies.
Mini desserts: assemble in 8 (4-oz) mason jars for picnic-friendly portions—reduce chill time to 2 hours.
Mocha twist: dissolve 1 tsp instant espresso powder into the warm cream before pouring over chocolate.

Storage Tips

Tent the pie with foil (or place in a large cake carrier) and refrigerate up to 5 days. After day 2, press plastic wrap directly against the cut edges to prevent the ganache from drying. The pie can be frozen up to 2 months: chill until ganache is firm, wrap the whole plate in a double layer of plastic, then foil. Thaw overnight in the refrigerator; ganache may dimple slightly but flavor remains intact. Do not freeze individual slices without a tight seal—ice crystals will turn the mousse grainy.

Frequently Asked Questions

Natural styles separate and contain varying oil levels, which can cause the mousse to weep or become dense. If it’s all you have, stir very well, measure 1 cup, then blot excess oil with a paper towel; still, expect a slightly less fluffy texture.

Rapid temperature swings cause chocolate to contract. Add the corn syrup (or honey) and cool the ganache 5 minutes before glazing; refrigerate gently, away from the back wall where temps are coldest.

Yes—use a 6-inch springform pan and halve every ingredient. Chill time remains the same.

Chill overnight, then set the pie plate inside a large, clean stockpot with a lid; the tall sides protect the ganache. Add a few frozen gel packs around the plate and drive with the A/C on or in a cooler bag.

Wait until the ganache is just set (30 minutes in fridge), then pipe rosettes of stabilized whipped cream or extra peanut butter mousse; finish chilling so the décor firms up.

Because it contains dairy, don’t let the pie sit above 40 °F for more than 2 hours. Nest the plate in a shallow tray of ice or serve from a chilled platter.
