These Nutella Swirl Brownies are a dreamy combination of rich, fudgy chocolate and creamy hazelnut spread. The Nutella is swirled into the top of the brownie batter before baking, creating a marbled effect that’s not just beautiful, but indulgently delicious. Perfect for casual baking, potlucks, or anytime you need a hit of chocolate comfort.
