Step-by-Step Instructions
Step 1: Prep the pan and oven
Preheat the oven to 350°F (175°C). Place a rack in the middle of the oven.
Use a standard 9-inch (23 cm) pie dish (glass or metal both work). No need to grease it for a cookie crust.
Step 2: Make and bake the cookie crust
Add the cookies to a food processor and pulse into fine crumbs. You should have about 2 1/2 cups of crumbs. (No food processor? Put cookies in a zip-top bag and crush with a rolling pin.)
Mix crumbs with the 1 Tbsp sugar and a pinch of salt, then pour in the melted butter. Stir until the texture looks like wet sand and holds together when pressed.
Press firmly into the bottom and up the sides of the pie dish, using the bottom of a measuring cup to compact it.
Bake for 10 minutes, then set on a rack to cool completely, about 30–40 minutes. (The crust must be fully cool before filling.)
Step 3: Melt the chocolate and cool it slightly
Place chopped chocolate in a microwave-safe bowl. Microwave at 50% power in 30-second bursts, stirring well between each, until smooth (usually 1 1/2 to 2 1/2 minutes total depending on your microwave).
Set aside to cool until it’s lukewarm, about 85–90°F (29–32°C). It should be fluid but not hot (hot chocolate can melt the butter and make the filling greasy).
Step 4: Heat the eggs and sugar to 160°F (for a safe, silky base)
Set up a double boiler: fill a saucepan with 1 inch (2.5 cm) of water and bring to a gentle simmer. Place a heatproof bowl on top (the bowl should not touch the water).
In the bowl, whisk together the eggs, granulated sugar, and 1/4 tsp salt. Whisk constantly over the simmering water until the mixture reaches 160°F (71°C) on an instant-read thermometer, about 6–8 minutes. It should look lighter in color and slightly thicker.
Remove from heat and whisk in the vanilla. Let the mixture cool for 10 minutes, whisking occasionally, until it’s warm but not hot (aim for 90–95°F / 32–35°C or cooler).
Step 5: Whip the French silk filling until airy
In a stand mixer fitted with the paddle attachment (or a large bowl with a hand mixer), beat the room-temperature butter on medium-high until very pale and fluffy, about 3 minutes. Scrape down the bowl.
With the mixer running on medium, slowly pour in the lukewarm melted chocolate. Mix until fully blended and glossy, about 30–45 seconds. Scrape down the bowl.
With the mixer on medium-low, slowly drizzle in the warm egg-sugar mixture. Once it’s all added, increase speed to medium-high and beat until the filling looks lighter, silkier, and slightly increased in volume, about 2–3 minutes. Scrape down the bowl and mix for 10 seconds more.
Spoon the chocolate filling into the cooled crust and smooth the top with an offset spatula.
Step 6: Make the peanut butter swirl and marble it in
In a small bowl, stir together the peanut butter, powdered sugar, and heavy cream until smooth and ribbon-like. If it seems too thick to swirl, add an additional 1 tsp (5 ml) cream.
Dollop the peanut butter mixture over the chocolate filling in 8–10 small spoonfuls. Use a butter knife or skewer to swirl: make gentle figure-eight motions, keeping the knife mostly near the surface so you get defined ribbons (avoid over-mixing or the swirl will disappear).
Step 7: Chill until sliceable
Refrigerate the pie, uncovered, for 30 minutes to firm the surface, then cover gently (tent with foil or use a pie keeper) and chill until fully set, at least 6 hours and preferably overnight (10–12 hours).
Step 8: Finish with whipped cream and peanuts
Just before serving, whip the cold heavy cream, powdered sugar, and vanilla to medium peaks (soft but scoopable), about 2–4 minutes with a hand mixer on medium-high.
Spread or pipe whipped cream over the chilled pie. Sprinkle with chopped salted peanuts and, if you like, a tiny pinch of flaky sea salt.
For clean slices, cut with a sharp knife dipped in hot water and wiped dry between cuts.
Pro Tips
- Temperature matters: Keep butter at true room temperature (68–72°F / 20–22°C). If it’s too cold, the filling won’t get airy; too warm and it can turn greasy.
- Don’t rush the egg step: Hitting 160°F (71°C) while whisking constantly gives you a safe base and helps dissolve the sugar for a smoother silk texture.
- Cool the chocolate: Melted chocolate should be lukewarm, not hot, so it blends seamlessly with the butter.
- Swirl lightly: A few gentle passes make distinct peanut butter ribbons; too much swirling turns the top one uniform color.
- Chill long enough: For neat slices, give it the full 6 hours (overnight is even better).
Variations
- Chocolate peanut butter cup vibe: Add 1/2 cup (75 g) mini chocolate chips on top of the chocolate filling before swirling in the peanut butter.
- Extra-salty finish: Swap chopped peanuts for chopped salted pretzels (about 1/2 cup / 45 g) for a sweet-salty crunch.
- Dark chocolate intensity: Use 70–72% chocolate and increase sugar to 7/8 cup (175 g) if you prefer a sweeter balance.
Storage & Make-Ahead
Refrigerate: Cover and store the pie in the refrigerator for up to 4 days. For the best texture, add the whipped cream topping within 24 hours of serving (or stabilize it by whipping to slightly firmer peaks).
Make-ahead: This pie is ideal made 1 day ahead. Chill the fully assembled pie (without whipped cream) overnight, then top shortly before serving.
Freeze: You can freeze the pie (without whipped cream) tightly wrapped for up to 1 month. Thaw overnight in the refrigerator. Add whipped cream and peanuts after thawing.
