Or how to make boxed brownies better.
I feel guilty even writing this a blog post because it's so easy, but I always like sharing helpful tips like this. And while you'll need to have some kind of Oreo for this, you'll need one more ingredient that I bet you always have in your kitchen. It's probably even something you have every day. And you'll need so little of it that you can just put it aside in the morning.
Are you ready?
