<human>:  How do I make a vegan chocolate cake?
<bot>: To make a vegan chocolate cake, you will need the following ingredients: 1/2 cup vegetable oil, 2 cups all-purpose flour, 1 cup granulated sugar, 1/4 cup unsweetened cocoa powder, 1 teaspoon baking powder, 1 teaspoon baking soda, 1/2 teaspoon salt, 1 cup warm water, and 1 teaspoon vanilla extract. Preheat oven to 350ºF (177ºC). Grease a 9-inch round cake pan. In a large bowl, mix together oil, flour, sugar, cocoa powder, baking powder, baking soda and salt. Add the warm water and vanilla extract and mix until just combined. Pour the batter into the prepared cake pan. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Allow the cake to cool before serving. Enjoy!
