User: What is the best recipe for a chocolate cake?
Assistant: The best recipe for a chocolate cake is one that uses cocoa powder and melted chocolate to create a rich and tender cake. Start by whisking together eggs, sugar, oil, and vanilla until light and fluffy. Then sift together flour, cocoa powder, baking soda, and salt. Combine the liquid and dry ingredients and mix until combined. Finally, stir in melted chocolate and pour the batter into a greased and floured baking pan. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let the cake cool completely before frosting and serving. Enjoy!
