Description

These No-Bake Chocolate Mousse Bars combine a crisp chocolate cookie crust with a rich, airy chocolate mousse and a smooth chocolate ganache topping. Perfect for chocolate lovers, these delicious bars require no baking and come together quickly, making them an ideal dessert for any occasion.


Ingredients

Crust

  • 2 cups chocolate cookie crumbs
  • ½ cup melted butter

Mousse Filling

  • 1 ½ cups heavy cream
  • 1 cup semisweet chocolate chips, melted
  • ¼ cup powdered sugar
  • 1 teaspoon vanilla extract

Chocolate Layer

  • ¾ cup semisweet chocolate chips
  • ½ cup heavy cream

Garnish

  • ½ cup whipped cream
  • Chocolate shavings or cocoa powder (optional)


Instructions

  1. Prepare the Crust: In a bowl, thoroughly mix the chocolate cookie crumbs with the melted butter to combine evenly, creating a crumbly mixture.
  2. Press into Pan: Firmly press the crumb mixture into the bottom of an 8×8-inch baking dish, ensuring an even and compact base.
  3. Chill the Crust: Place the crust in the refrigerator to set while preparing the mousse filling.
  4. Make the Mousse: Using a mixer, beat the heavy cream, melted semisweet chocolate chips, powdered sugar, and vanilla extract together until the mixture becomes light, fluffy, and smooth.
  5. Spread Mousse: Evenly spread the prepared chocolate mousse over the chilled cookie crust, creating a smooth layer.
  6. Refrigerate the Mousse: Place the dish back in the refrigerator to chill while preparing the chocolate ganache layer.
  7. Prepare Chocolate Layer: Gently heat the heavy cream until warm but not boiling.
  8. Make Ganache: Pour the warm cream over the semisweet chocolate chips and let it sit for one minute. Stir gently until the mixture becomes smooth and glossy.
  9. Spread Ganache: Pour and spread the melted chocolate ganache evenly over the mousse layer.
  10. Chill Completely: Refrigerate the assembled bars for at least 4 hours or until the layers are fully set.
  11. Garnish and Serve: Before serving, top the bars with whipped cream and optionally garnish with chocolate shavings or a dusting of cocoa powder.
  12. Slice and Enjoy: Slice the bars into 12 equal pieces and enjoy this rich, no-bake chocolate dessert.

Notes

  • Ensure the heavy cream for the ganache is warm but not boiling to prevent seizing of chocolate.
  • Use a fine chocolate cookie crumb for the crust for best texture.
  • Chilling time is key for setting the layers properly; do not skip refrigeration.
  • For a dairy-free version, substitute with coconut cream and dairy-free chocolate chips.
  • Store leftovers covered in the refrigerator for up to 3 days.
