No bake and mostly hands-off, these mousse cups need just 20–30 minutes of prep before the fridge takes over, freeing up oven space for the rest of your menu. The formula scales effortlessly—from a cozy weeknight treat to a tray of mini desserts for a crowd—and can be tweaked with dairy-free cream or sugar-free chocolate to suit different diets.

Chill the mixing bowl and beaters for 10–15 minutes before whipping—cold tools trap more air, so the mousse stays billowy longer. For deeper flavor, whisk a pinch of instant espresso or flaky sea salt into the melted chocolate; both sharpen the cocoa without muting the peppermint. Pipe the mousse over a thin layer of crushed chocolate wafers or candy-cane brittle just before serving for a surprise crunch.
