Human: I'd like to make some fudge for the holidays. What is the best recipe? Assistant: 
The best recipe for fudge is one that includes butter, sugar, cocoa powder, and vanilla extract. Start by melting the butter in a saucepan over medium heat. Add the sugar and cocoa powder and stir until combined. Remove from heat and stir in the vanilla extract. Finally, add your favorite flavorings such as nuts, coconut, or chocolate chips. Pour the mixture into an 8x8-inch pan lined with wax paper or parchment paper. Allow the fudge to cool before slicing and serving. Enjoy!
