Pumpkin-Chocolate Torte with Pumpkin Whipped Cream

To prepare torte: Preheat oven to 350 degrees F.

Coat a 9-inch springform pan with cooking spray. Line the bottom with parchment paper and spray the paper.

Combine 1/2 cup chocolate chips, butter and oil in a small saucepan. Place over medium-low heat, stirring frequently with a spatula, until melted.

Beat eggs, egg whites, 1 cup pumpkin, 1/2 cup sugar, cocoa powder, 1 teaspoon vanilla, pumpkin pie spice and salt in a large mixing bowl with an electric mixer on medium speed for 5 minutes. Add the melted chocolate and beat until combined. Scrape the batter into the prepared pan.

Bake the torte in the middle of the oven until the edges are set and the center just barely jiggles when the pan is gently shaken, 30 to 40 minutes. Let cool on a wire rack to room temperature, about 1 1/2 hours.

Melt the remaining 1/4 cup chocolate chips (see Tip). Decoratively drizzle the melted chocolate over the top of the cooled torte. Cover the pan with plastic wrap and refrigerate until chilled, about 2 hours (or up to 1 day).

To prepare topping: Just before serving, beat cream with 1 tablespoon sugar in a medium bowl with an electric mixer until soft peaks form. Add 1/2 teaspoon vanilla and continue to beat until stiff peaks form. Gently fold in 2 tablespoons pumpkin puree. Remove the pan sides and slice the torte. Serve each portion with a dollop (about 1 tablespoon) of the pumpkin whipped cream.
