<bot>: To make a delicious homemade chocolate cake, you will need the following ingredients: all-purpose flour, cocoa powder, baking soda, baking powder, salt, unsalted butter, granulated sugar, light brown sugar, eggs, vanilla extract and milk. Preheat your oven to 350°F (180°C). Grease and flour a 9x13 inch pan. In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder and salt. In a large bowl, beat the butter until creamy. Gradually add in the sugars and beat until fluffy. Add the eggs one at a time, beating well after each addition. Add the dry ingredients and mix until just combined. Slowly stir in the milk and vanilla extract. Pour the batter into the prepared pan and bake for 30 minutes or until a toothpick inserted into the center comes out clean. Cool completely before slicing and serving. Enjoy!
