Peanut Butter Swirl Brownies

I'll bring snacks to a group thing, and I wanted to do something a little different, but something I hope everyone eats and like. Would you try to swirl brownies with peanut butter or just regular brownies would be better?

which could be delicious. just does not add much peanut butter.

mmmmm yummy, I tried the chocolate brownie peanut butter and they are great, the only thing is that some people might be allergic to peanuts, so tell them before they eat = /

Pillsbury has a premix like that, its flippin awesome
