Nutella-and-Marshmallow-Stuffed Brownies

I used The Baked Brownie recipe to make these Nutella-and-Marshmallow-stuffed brownies, because it is the last brownie recipe you'll ever need.  I just spread half the batter in the pan, drizzled Nutella over it, then drizzled Marshmallow Cream (which I purchased for the first time specifically for this recipe), then covered with the remaining half of the brownie batter.

I was expecting them to be "too much."

But, um, hello.  They were amazing.
