Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.
  2. In a mixing bowl, beat together butter and sugars until fluffy. Add egg and vanilla; mix well. Gradually blend in buttermilk.
  3. In another bowl, whisk together flour, cocoa powder, baking soda, and salt. Combine dry ingredients with the wet mixture until just combined. Fold in cinnamon chips.
  4. Divide batter between prepared pans and bake for about 25 minutes or until a toothpick comes out clean. Allow cooling before removing from pans.
  5. For the mousse layers, prepare each by dissolving gelatin in water, then mixing it with warmed heavy cream along with pumpkin puree and spices as needed.
  6. Assemble by layering chocolate cake with mousse mixtures until all layers are stacked; finish with ganache topping.
