By leelee30

Ingredients

• 8 tablespoons (1 stick) unsalted butter, plus more for pan
• 6 ounces bittersweet chocolate, chopped
• 2 cups all-purpose flour
• 1 teaspoon baking powder
• 1/4 teaspoon cayenne pepper
• 1/2 teaspoon salt
• 1 3/4 cups sugar
• 4 large eggs
• 1 tablespoon pure vanilla extract
• 1 1/4 cups solid-pack pumpkin
• 1/4 cup vegetable oil
• 1 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 1/2 cup chopped hazelnuts or other nuts

Preparation

Step 1

•Preheat oven to 350 degrees. Butter a 9-inch square baking pan or dish. Line bottom of pan with parchment paper; butter lining.
-Melt chocolate and butter in a heatproof bowl set over a pan of simmering water, stirring occasionally until smooth.
-Whisk together flour, baking powder, cayenne, and salt in a large bowl; set aside. Put sugar, eggs, and vanilla in the bowl of an electric mixer fitted with the paddle attachment; beat until fluffy and well combined, 3 to 5 minutes. Beat in flour mixture.
-Divide batter between two medium bowls (about 2 cups per bowl). Stir chocolate mixture into one bowl. In other bowl, stir in pumpkin, oil, cinnamon, and nutmeg. Transfer half of chocolate batter to prepared pan smoothing top with a rubber spatula. Top with half of pumpkin batter. Repeat to make one more chocolate layer and one more pumpkin layer. Work quickly so batters don't set.
-With a small spatula or a table knife, gently swirl the two batters to create a marbled effect. Sprinkle with nuts.
-Bake until set, 40 to 45 minutes. Let cool in pan on a wire rack. Cut into 16 squares.
