Ingredients Nonstick cooking spray 1 ¼ cups all-purpose flour (spooned and leveled) ¼ cup unsweetened cocoa powder ¾ teaspoon baking powder ½ teaspoon coarse salt ½ cup (1 stick) unsalted butter, cut into pieces 8 ounces bittersweet chocolate, chopped 1 cup sugar 3 large eggs, lightly beaten 1 cup walnut halves, coarsely chopped 1 cup semisweet chocolate chips (6 ounces) Directions Lightly coat a 5-quart slow-cooker insert with cooking spray. Line bottom with parchment paper and lightly coat with spray. In a small bowl, whisk together flour, cocoa, baking powder, and salt. Place butter and chocolate in a medium microwave-safe bowl and microwave in 30-second increments, stirring after each, until chocolate is melted. Add sugar; stir to combine. Stir in eggs. Add flour mixture, walnuts, and chocolate chips and stir just until moistened (do not overmix). Transfer to slow cooker and smooth top. Cover and cook on low, 3 1/2 hours. Uncover and cook 30 minutes. Remove insert from slow cooker and run a knife around edge to loosen brownies. Let cool completely in insert on a wire rack, about 2 hours. Turn out onto a work surface and cut into 14 brownies. Store in an airtight container, up to 2 days. Cook's Notes The center may look undercooked when time is up, but it will be perfect once cooled.
