All you have to do is find a few recipes to see what ingredients are always there - like flour, sugar, backing powder (or soda) and use those pretty much to a T. This way, you know you at least have the right base.





You can basically play with everything else from there - chocolate, vanilla, eggs, nuts, etc.How do you make a brownie recipe you came up with?
I would find a regular recipe and add things to it... I would put chocolate frosting on it and then decorate it with white chocolate chips in different designs also try adding a dash of cinnimon and make it interesting. GOOD LUCK
