Soft & chewy Nutella Brownies have a crackly top, a moist center and are full of rich chocolate hazelnut flavor! Swirls of Nutella and melting chocolate chips in every bite make these brownies extra decadent and delicious! These Nutella Brownies might just be my best brownie yet! They bake up so moist, so rich and so full of chocolate and hazelnut flavors. You won’t be able to resists the swirls of Nutella and melting chocolate chips in every bite.
