These no-fuss chocolate brownies get a subtle kick of spice that brings this all-time favorite dessert to the next level.
Spicy Cinnamon-Chocolate Brownies
Vegetable oil cooking spray, for greasing pan
One 21-ounce box brownie mix, such as Duncan Hines Chewy Fudge
3 large eggs, at room temperature
1/2 cup vegetable oil
1 tablespoon ground cinnamon
1/2 teaspoon cayenne pepper
Position an oven rack in the lower third of the oven. Preheat the oven to 350 degrees F. Spray a 9-by-13-inch ceramic or glass baking dish with vegetable oil cooking spray. Line the dish with a 15-inch-square piece of parchment paper, allowing the excess paper to overhang the sides. Spray the parchment paper with vegetable oil cooking spray.
Blend together the brownie mix, eggs, vegetable oil, 1/4 cup water, cinnamon and cayenne pepper in a large bowl. Beat the mixture for 1 minute using an electric hand mixer on medium speed. Pour the batter into the prepared pan. Bake until a toothpick inserted about 1-inch from the edge of the baking dish comes out clean, 25 to 27 minutes. Transfer the pan to a wire rack to cool for 1 hour.
Lift the brownie layer from the pan, using the excess paper for handles. Run a thin spatula underneath the brownie layer to loosen it from the parchment paper. Cut into squares and serve.
