<bot>: To make a delicious homemade chocolate cake, you will need the following ingredients and supplies: all-purpose flour, cocoa powder, baking soda, baking powder, salt, butter, sugar, eggs, vanilla extract, and milk. Preheat your oven to 350°F (177°C). Grease and flour a 9x13 inch pan. In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt; set aside. In a large bowl, cream together the butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Beat in the vanilla extract. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Add the milk and mix until everything is completely moistened. Pour the batter into the prepared pan and bake for 25-30 minutes or until a toothpick inserted into the center of the cake comes out clean. Allow the cake to cool before serving. Enjoy!
