French Silk Pie Recipe

French silk pie is a chilled chocolate pie: a baked crust filled with butter and sugar beaten until fluffy, melted semi-sweet chocolate, and whipped cream folded through until the filling turns light and mousse-like. A layer of sweetened whipped cream and chocolate curls goes on top. This version uses no eggs at all.

Plan on about 25 minutes of hands-on work and at least 4 hours in the fridge for one 9 inch pie, which cuts into 8 slices. It is the pie I make when guests ask for something creamy and chocolatey, and it takes turns on my table with coconut cream pie.

What Is French Silk Pie, and What Is Inside?

Despite the name, French silk pie is American. It goes back to a 1951 Pillsbury Bake-Off entry called French Silk Chocolate Pie, and “silk” describes the filling: smooth, airy and soft enough to cut with a fork, but firm enough to hold a clean edge once chilled.

There are three layers in this one:

• Crust: one pre-baked 9 inch pie crust, homemade or store-bought, fully cooled.
• Filling: 1 cup butter, 1 ½ cups granulated sugar, 4 oz melted semi-sweet chocolate, vanilla, salt, and 1 cup heavy cream whipped with 3 tablespoons powdered sugar.
• Topping: 1 ¼ cups heavy cream whipped with 2 tablespoons powdered sugar and ½ teaspoon vanilla, plus chocolate curls or shavings.

Raw Eggs or No Eggs: Two Ways to Make Silk Pie

The original filling is made by beating raw eggs, one at a time, into the butter, sugar and chocolate. The eggs dissolve the sugar and trap air, but they are never cooked, so there is a small risk of salmonella. If you make that version, use pasteurized eggs, or follow a recipe that cooks the eggs with the sugar over a water bath to 160°F before cooling and beating.

This recipe skips eggs completely. The air comes from stiffly whipped cream folded into the chocolate butter, so there is nothing raw to worry about, and the filling sets slightly lighter and creamier, closer to a mousse. The tradeoff: without eggs to dissolve the sugar, the butter and sugar need a long beating, which is the step most people rush.

Choosing a Crust for Chocolate Silk Pie

The filling is never baked, so any 9 inch crust works as long as it is fully baked and completely cool. A homemade flaky pie crust blind baked until the bottom is deep golden gives the best contrast with the soft filling. A frozen store-bought shell baked according to the package is fine on a busy day.

A graham cracker or chocolate cookie crust works too, like the one in my Oreo pie. Bake the crust the night before if you like, let it cool, then wrap it and keep it in the fridge until you fill it. A warm crust softens the butter in the filling and makes the bottom soggy.

Beating the Butter and Sugar Until It Stops Feeling Sandy

Start with butter soft enough that a finger leaves a dent, but not shiny or greasy. Beat it with the granulated sugar on high speed for 5 to 7 minutes, scraping the bowl twice. It should turn pale, almost white. Think frosting.

Here is the test. Rub a little between your thumb and finger. If it still feels sandy, keep beating. Undissolved sugar is what makes a silk pie taste grainy. Superfine sugar dissolves faster if you have it.

Then add the melted chocolate, vanilla and salt. The chocolate needs to be cooled until barely warm, about body temperature, and still fluid. Too hot and it melts the butter you just whipped. Too cold and it sets into little chocolate flecks instead of blending in.

Folding In the Cream Without Losing the Air

Whip the 1 cup of cold heavy cream with the powdered sugar to stiff peaks. The cream should stand up on the whisk and still look smooth, not lumpy or grainy. Overwhipped cream turns buttery and will not fold in smoothly.

Add the cream to the chocolate in three batches. Stir the first third in briskly to loosen the chocolate butter. Fold the next two in gently with a spatula, cutting down the middle and turning the bowl, just until no white streaks remain. Spoon it into the cooled crust and smooth the top.

I once tried Cool Whip here as an experiment. It worked, but the texture was not the same, and fresh cream is what I use now.

How Long to Chill French Silk Pie

At least 4 hours. Overnight is better. The butter firms up as it chills, and that is what lets the filling hold a clean edge. Cover the pie loosely with plastic wrap so it does not pick up fridge smells. Cut it early and the slices slump.

Whip the topping just before serving: 1 ¼ cups cream, 2 tablespoons powdered sugar and ½ teaspoon vanilla, to soft peaks. Spread it with an offset spatula. It is the same method as my whipped cream frosting, just a softer peak. For curls, run a vegetable peeler along the side of a chocolate bar at room temperature. A cold bar gives fine shavings instead.

For neat slices, dip a sharp knife in hot water, wipe it dry, and clean it between every cut.

Grainy, Soupy or Speckled Filling: What Went Wrong

• Grainy: the sugar did not dissolve. Beat longer before the chocolate goes in, and check with the finger test.
• Soupy after folding: the chocolate or butter was too warm. Chill the bowl for 15 minutes, then beat briefly on medium until it thickens.
• Tiny chocolate specks: the chocolate was too cool and set on contact with the butter. It still tastes good; next time add it while it is fluid.
• Dense and heavy: the cream was underwhipped or stirred in hard. Whip to stiff peaks and fold the last two batches gently.

Does French Silk Pie Need to Be Refrigerated?

Yes. The filling is butter and cream, so keep the pie in the fridge and do not leave it out for more than 2 hours. Covered, it keeps for up to 3 days. Slice what you need. The rest goes straight back.

To freeze it, chill the pie until firm, leave the whipped cream topping off, and wrap it tightly in plastic and foil. It keeps for about a month. Thaw it overnight in the fridge, then whip fresh cream for the top. Frozen whipped cream weeps and separates as it thaws.

Leftover filling makes a quick mousse. Spoon it into small glasses and chill.

More Chocolate Pies and Fillings

If you like this one, try chocolate cream pie, or chocolate pudding pie. For layer cakes, the same airy texture comes from my chocolate mousse filling. A banana cream pie next to it makes a good two-pie holiday table.

Silk Pie Questions

Does French silk pie have raw eggs?

Traditional recipes do. This one has no eggs at all; whipped cream gives the filling its lift.

Can I make French silk pie with cocoa powder?

This recipe relies on 4 oz of melted semi-sweet chocolate for both flavor and set. Cocoa powder has no cocoa butter to firm the filling, so it is not a straight swap.

How far ahead can I make it?

Fill the pie up to a day ahead and keep it chilled. Add the whipped cream and curls just before serving.
