This chocolate parfait has layers of smooth chocolate mousse, fluffy whipped cream, and crunchy Oreo crumbs. It looks beautiful in glass cups and takes just 30 minutes to make.
Melt the dark chocolate and heavy cream together in a bowl. Microwave in 15-second bursts, stirring until smooth. Let it cool slightly.
In a large bowl, combine the cold heavy cream, sifted cocoa powder, powdered sugar, and vanilla. Beat with a hand mixer until stiff peaks form.
Pour the cooled melted chocolate into the whipped cream. Mix briefly with the hand mixer, then fold with a spatula until smooth.
Make the whipped cream
In a clean bowl, beat the cold heavy cream, vanilla, and powdered sugar until stiff peaks form.
Assemble and chill
Divide the ingredients evenly into your glasses. Put 1 tablespoon of Oreo crumbs at the bottom, pipe in a layer of chocolate mousse, and top with vanilla whipped cream.
Repeat the layers one more time. Top with extra Oreo crumbs for decoration.
Refrigerate the glasses for at least 1 to 3 hours so the layers can firm up before serving.
Notes
Keep Cream Ice-Cold: Always use heavy cream straight from the fridge. Warm cream will not trap air properly and will fail to whip into thick peaks.
Cool the Melted Chocolate: Let the melted chocolate cool slightly before adding it to the whipped cream. If it is too hot, it will melt the cream and ruin the fluffy texture.
Sift the Cocoa Powder: Always sift your cocoa powder into the bowl. This removes tight lumps that are difficult to beat out later.
Pipe for Clean Layers: Use piping bags to add the mousse and whipped cream to the glasses. This creates sharp, clean layers without smudging the sides of the glass.
