Ingredients

Scale

Chocolate Cake

  • 4 oz unsalted butter (at room temperature)
  • 3.5 oz granulated sugar (1/2 cup)
  • 3.75 oz brown sugar (1/2 cup)
  • 2 large eggs (at room temperature)
  • 2 tsp vanilla extract
  • 5.3 oz all-purpose flour (1 1/3 cup)
  • 2 oz unsweetened cocoa powder (2/3 cup)
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 8 fl oz buttermilk (1 cup, at room temperature)

Candy Cane Mousse

  • 18 oz white chocolate chips
  • 3.5 cups heavy cream
  • 1/2 tsp salt
  • 4 tsp unflavored powdered gelatin
  • 4 TBSP water
  • 1 tsp peppermint extract
  • 8 oz Andes peppermint crunch baking bits (1 1/3 cup, or similar chocolate-mint pieces)

Ganache and Decoration

  • 4 fl oz heavy cream (1/2 cup)
  • 3 oz semi-sweet chocolate (finely chopped)
  • Peppermint candies (peppermint bark, lollipops, ribbon candy, candy canes, etc.)

Instructions

  1. Prepare the Chocolate Cake: Preheat your oven to 350°F (175°C). Line two 9-inch cake pans with parchment paper without spraying them. In a stand mixer with paddle attachment, cream the room temperature butter and both sugars on medium-high speed until light and fluffy, about 5 minutes. Add the eggs one at a time, mixing well after each addition. Mix in the vanilla extract fully.
  2. Mix Dry and Wet Ingredients: In a separate bowl, sift together flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients in quarters to the mixer on low speed, alternating with thirds of the buttermilk, beginning and ending with the dry ingredients. Stop mixing when almost combined, then finish folding gently by hand to avoid overmixing.
  3. Bake the Cake Layers: Divide batter evenly between the pans and smooth the tops. Bake for 22-25 minutes until a toothpick inserted comes out with few moist crumbs. Cool cakes completely on a wire rack. Cakes can be frozen for weeks if needed.
  4. Prepare the Cake Assembly Pan: Use a 9-inch pan with at least 3-inch sides and a removable bottom or springform pan. Line the inner sides with a 4-inch acetate cake collar or a tall strip of aluminum foil overlapping itself to create a mold for mousse layers. Place a cake board in the bottom to facilitate removal.
  5. Make the First Mousse Layer: In a microwave-safe bowl, combine 9 oz white chocolate chips, 3/4 cup cream, and 1/2 tsp salt. Microwave in 30-second intervals, stirring in between until smooth. Allow to cool to room temperature while preparing the gelatin.
  6. Prepare Gelatin: In a small bowl, whisk together 2 tsp powdered gelatin and 2 TBSP cold water. Let it absorb water for a few minutes, then microwave just long enough to melt (10-15 seconds). Whisk the melted gelatin into the cooled white chocolate mixture with 1/2 tsp peppermint extract.
  7. Whip and Fold Cream: Whip 1 cup heavy cream to firm peaks. Fold half into the white chocolate mixture gently, then fold in the remaining whipped cream. Stir in 2/3 cup Andes peppermint bits carefully to distribute evenly.
  8. Assemble First Mousse Layer: Place one chocolate cake layer on the cake board in the pan, then smooth the mousse on top in an even layer. Refrigerate 15 minutes until mousse begins to set and is firm enough to hold the next layer.
  9. Repeat for Second Layer: Place the second cake layer on top of the chilled mousse. Repeat the mousse making and spreading process to cover the top. Refrigerate for 5-6 hours or overnight until the mousse is fully set and firm.
  10. Make the Ganache: Remove the cake from the pan by pushing out the bottom or releasing the sides and unwrap the acetate. On a small bowl, pour hot cream (heated to a simmer) over 3 oz chopped semi-sweet chocolate. Whisk gently until smooth and glossy.
  11. Glaze and Decorate: Pour the ganache over the mousse layer and spread gently towards edges allowing drizzles to drip. Let it sit for 10 minutes to slightly set. Decorate with assorted peppermint candies such as bark shards, candy canes, lollipops, and ribbon candy. Add candy no more than 1-2 hours before serving to avoid stickiness.
  12. Serving: For neat slices, chill the cake well before cutting. Use a large sharp knife and clean it between slices. Let cake slices stand at room temperature 10-15 minutes before serving for best texture and flavor.

Notes

  • Ensure butter, eggs, and buttermilk are at room temperature for best cake texture.
  • The acetate cake collar or foil lining prevents mousse from sticking to the pan sides, enabling clean removal.
  • Gelatin must be fully dissolved and incorporated for mousse to set properly.
  • Andes peppermint crunch bits add texture and peppermint flavor; substitute with similar peppermint chocolate bits if unavailable.
  • Allow mousse layers to chill well for easy assembly and cutting.
  • Decorate with peppermint candies shortly before serving to keep them crisp and avoid stickiness.
  • Storing: Cake can be stored covered in the refrigerator up to 3 days.
