<human>: I'm looking for a good recipe to make a chocolate cake. Can you help me?
<bot>: Yes, of course! To make a delicious chocolate cake, you will need the following ingredients: 2 cups all-purpose flour, 1 cup white sugar, ½ cup cocoa powder, 1 teaspoon baking soda, ¼ teaspoon salt, 1 cup vegetable oil, 1 cup water, 1 teaspoon vanilla extract, and 3 tablespoons vinegar. Preheat your oven to 350°F (175°C). In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt. In a separate bowl, mix together the oil, water, vanilla extract, and vinegar. Add the wet ingredients to the dry ingredients and stir until combined. Grease and flour a 9x13 inch pan. Pour the batter into the prepared pan. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Allow the cake to cool before serving. Enjoy!
