Ingredients
- 1 1/2 cups graham cracker crumbs
- 1/4 cup granulated sugar
- 6 tbsp unsalted butter, melted
- 1 1/2 cups pumpkin puree
- 3 large eggs
- 1/2 cup granulated sugar
- 1 tsp vanilla extract
- 1 tsp pumpkin pie spice
- 1/4 tsp salt
- 1 cup heavy cream
- 8 oz semisweet chocolate, chopped
Equipment Needed
- 9-inch springform pan
- Mixing bowls
- Electric mixer
- Rubber spatula
- Double boiler or microwave-safe bowl
Instructions
Prepare the Crust
Start by preheating your oven to 350°F. In a medium bowl, mix the graham cracker crumbs, 1/4 cup sugar, and melted butter until the mixture resembles wet sand. Press firmly into the bottom of a 9-inch springform pan. Bake for 10 minutes, then let cool. Tip: For a firmer crust, freeze it for 10 minutes before baking.
Make the Pumpkin Layer
In a large bowl, whisk together the pumpkin puree, eggs, 1/2 cup sugar, vanilla extract, pumpkin pie spice, and salt until smooth. Pour over the cooled crust. Bake in a water bath for 45 minutes at 350°F until the center is just set. Tip: Cover the pan with foil to prevent browning if necessary.
Prepare the Chocolate Mousse
While the pumpkin layer cools, heat the heavy cream until hot but not boiling. Pour over the chopped chocolate, let sit for 2 minutes, then stir until smooth. Let cool to room temperature, then fold in whipped cream until no streaks remain. Spread over the cooled pumpkin layer. Tip: For extra fluffiness, whip the cream to soft peaks before folding into the chocolate.
Chill and Serve
Refrigerate the cake for at least 4 hours, or overnight, to set the mousse. Before serving, run a knife around the edge of the pan to loosen, then remove the springform ring. Slice with a warm knife for clean cuts.
Tips and Tricks
For the best texture, ensure all ingredients are at room temperature before starting. This helps them blend more smoothly. When making the mousse, be patient with the chocolate mixture; rushing the cooling process can lead to a grainy texture. If you’re short on time, you can speed up the chilling process by placing the cake in the freezer for 1-2 hours, but be sure to transfer it to the fridge to thaw slightly before serving for the best texture.
Recipe Variations
- Swap the graham cracker crust for a chocolate cookie crust for an extra chocolatey base.
- Add a layer of caramel between the pumpkin and mousse layers for a sweet surprise.
- Incorporate a teaspoon of espresso powder into the chocolate mousse for a mocha twist.
- Top the finished cake with whipped cream and a sprinkle of cinnamon for added flair.
- Use white chocolate instead of semisweet for a sweeter, creamier mousse.
