Rich and creamy chocolate mousse layered with “dirt” cookie crumbs, gummy worms, and cookie gravestones makes for a hauntingly fun dessert that’s as festive as it is delicious.
In a heatproof bowl, melt chocolate and butter over a saucepan of simmering water (or in microwave in 20-sec bursts).
Stir until smooth, then set aside to cool slightly.
In a bowl, whisk egg yolks with ¼ cup sugar until pale and thick.
Stir yolk mixture into melted chocolate.
In another bowl, beat egg whites with a pinch of salt until soft peaks form.
Gradually add 2 tbsp sugar and beat until stiff, glossy peaks form.
Gently fold whipped cream into chocolate mixture.
Then fold in egg whites until just incorporated (don’t overmix).
Spoon mousse evenly into 6 cups or jars.
Chill in fridge for at least 1 hour to set.
Sprinkle cookie “dirt” crumbs over each mousse cup.
Write “RIP” on rectangular cookies with writing gel or melted chocolate, then insert into mousse as gravestones.
Add gummy worms, candy pumpkins, or sprinkles for spooky flair.
(Optional) Pipe whipped cream ghosts with mini chocolate chip eyes.
Serve chilled on a spooky tray lined with candy corn or dry ice fog for dramatic effect.
Great as a Halloween party dessert or centerpiece.
Kid-friendly shortcut: Use store-bought chocolate pudding instead of homemade mousse.
Boozy twist (adults only): Add 1–2 tbsp coffee liqueur or Baileys to the chocolate base.
Vegan version: Use coconut whipped cream, dairy-free chocolate, and aquafaba in place of egg whites.
Make-ahead: Mousse can be made 1 day ahead; decorate just before serving.
