Double Peanut Butter Swirled Brownies

READY IN: 40mins
Recipe by MarthaStewartWanabe

These brownies are the perfect marriage of chewy, chocolaty, fudgy brownie and smooth swirls of peanut butter. They are also milk-free for those with allergies. Have a tall glass of ice-cold milk/Silk handy because these decadent treats are super rich.

The brownie part was really good, but I think next time, I'll add some powdered sugar to the peanut butter swirls. The peanut butter flavor was overpowering.
