Myst trust me when it comes to my baked goods you can't make them evil. Baked goods are always good or evil depending on who bakes them. If I bake them then they are mostly good but I have a few I am saving for some unsavory people that need them.
I have ninjas that liberate cookies that wish to join my army. Besides the burnt cookies can more easily be turned evil and those can in turn make the cookies from their batches evil!
Ah so I see that is how you do this. I was wondering how you have so many evil cookies running around. *takes down notes on how to fortify his many kitchens he has*
*hands you a bag of cookies* You may have these they were from the few I have that are evil but the other few I have are off limits. Especially the cookie that carries around a picture of it's mom.
