Cheesecake Marbled Brownies

There is no denying that these are very rich, but somehow the contrast between the intense chocolate and smooth cheesecake batter makes it less so. Originally I was going to make a marbled brownie with a blondie batter for the contrast, but I came across this recipe from the Smitten Kitten website and was rather taken with it.
I didn't change the recipe this time, as I have never made it before, and wanted to see how it turned out.

Before baking...

...and after

This is the third brownie recipe I have blogged, so I now have a label devoted to them, which pleases me greatly.
