GOOEY PUMPKIN CHOCOLATE SWIRL BARS

Steps:

• Heat oven to 350 degrees. Line a 9-x-13-inch baking pan with parchment paper and butter the paper.
• Spread pecans out on a rimmed baking sheet; toast until fragrant and lightly colored, 7 to 10 minutes. Cool and coarsely chop.
• Make the pumpkin batter: In a large skillet over medium heat, melt 12 tablespoons/170 grams butter. Cook until the foam completely subsides and butter turns a deep nut brown, about 5 minutes. Pour browned butter into the bowl of an electric mixer and let cool, about 10 minutes.
• Beat the pumpkin purée, egg, brown sugar and bourbon into the cooled browned butter. Scrape down the bowl and beat in baking powder, cinnamon, ginger, nutmeg and salt.
• Using a wooden spoon, mix in flour, then toasted pecans. Set aside.
• Make the chocolate batter: In a heatproof bowl set over a pan of simmering water, melt together 8 tablespoons/113 grams butter and the bittersweet chocolate, stirring with a heatproof spatula until smooth. Whisk in cocoa powder and sugar. Whisk in the eggs one at a time, then whisk in vanilla and salt. Using a spatula, fold in flour.
• Dollop pumpkin and chocolate batter into the prepared pan, alternating the dollops. Drag the tip of a knife in a zigzag pattern all over the pan to swirl the batters together.
• Bake until firm to the touch, 25 to 35 minutes. Transfer pan to a wire rack to cool completely before slicing.
