Brownie blondie swirl bars (best thing to bring to a potluck)

I couldnt find a recipe for these so I just combined two of my favorite recipe and wow, it was a big hit at a grad party.  I actually cant wait for the chance to make them again! You'll use 2 bowls and a small saucepan, but it's worth it.  We prefer ours without any additions but you could add in choc chips, toasted nuts, or chopped up candy bars leftover from Halloween.
