Minty Mousse Pie Au Chocolate

Mint-chocolate chips melted into a cornstarch-thickened base, then folded into whipped cream and piled into a graham cracker crust. This mousse pie is essentially a Thin Mint in pie form, and it requires zero baking.

The chocolate base gets cooked on the stovetop just long enough for the cornstarch to activate and the chips to melt into a thick, glossy pudding. Covering the surface with plastic wrap while it cools prevents a skin from forming. That skin would leave lumps in your otherwise silky mousse.

Folding the whipped cream into the cooled chocolate is the step that makes or breaks the texture. Stir too aggressively and you deflate all the air you whipped in. Use a gentle, sweeping fold until no white streaks remain.

Two to three hours in the fridge firms everything into a sliceable, cloud-like filling.

Kitchen Tips

• Cool the chocolate base to room temperature before folding in the cream. Hot chocolate melts the whipped cream and you lose all the lightness.
• Beat the heavy cream to stiff peaks, not just soft peaks. The mousse needs structure from the cream to hold its shape in the pie.
• Use a store-bought graham cracker crust for convenience, or make your own with crushed graham crackers and melted butter.
• Chill for the full 2-3 hours. Cutting early gives you a soft, oozy slice instead of clean wedges.

Variations

• Oreo crust: Swap the graham cracker crust for a crushed chocolate cookie crust to double down on the chocolate.
• Candy cane topping: Crush peppermint candies over the top before chilling for a holiday-ready presentation.
