Human: How can I make a delicious homemade chocolate cake? Assistant: 
To make a delicious homemade chocolate cake, you will need the following ingredients: all-purpose flour, cocoa powder, baking soda, baking powder, salt, butter, sugar, eggs, buttermilk, and vanilla extract. Preheat your oven to 350 degrees Fahrenheit (177 degrees Celsius). Grease and flour a 9x13 inch pan. In a large bowl, mix together the dry ingredients: flour, cocoa powder, baking soda, baking powder, and salt. In a separate bowl, cream together the butter and sugar until light and fluffy. Add the eggs one at a time, mixing well after each addition. Alternate between adding the buttermilk and the vanilla extract. Slowly add the wet ingredients to the dry ingredients and mix until fully combined. Pour the batter into the prepared pan and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Allow the cake to cool before serving. Enjoy!
