I love cooking and baking from scratch. I actually really love having the knowledge of being able to look at yeast and water and know how to make bread. But sometimes, it's more about the aesthetics than the actual treats. That's how I feel in this case. It's more important to spend your time decorating than it is to bake from scratch. But if you want to make from scratch, go right ahead. A boxed brownie won't be any better in this.
