Line an 8×8-inch baking dish with parchment paper, ensuring the sides are lightly coated with nonstick butter spray. Set aside.
In a large pan, melt the unsalted butter over medium heat. Once melted, add the chocolate chips and stir continuously until the chocolate has fully melted and combined with the butter.
Remove the pan from heat. Stir in the Rice Krispies cereal and kosher salt, ensuring the mixture is evenly combined.
Transfer the mixture into the prepared pan, spreading it evenly across the surface.
Allow the bars to cool and set for at least 1 hour before slicing and serving.
