Butter a 9×13-inch baking dish to prevent sticking and make removal easier once set.

In a large saucepan, melt 5 tablespoons of butter over medium heat. Add marshmallows, stirring continuously until completely melted and smooth. Remove from heat and stir in vanilla extract. In a large bowl, add Rice Krispie cereal. Pour the marshmallow mixture over the cereal and mix thoroughly until all cereal is coated. Transfer mixture to the prepared baking dish and press down gently to create an even layer. Set aside to cool slightly.

In another saucepan, combine sweetened condensed milk, 5 tablespoons of butter, and unwrapped caramels. Melt over medium heat, stirring constantly until caramels dissolve completely. Remove from heat and pour evenly over the Rice Krispie base. Sprinkle generously with sea salt. Allow to cool for about 15 minutes.

Heat heavy cream in a small saucepan over medium heat until it just begins to bubble. Remove from heat. Place milk chocolate chips in a separate bowl and slowly pour the warm cream over them, stirring gently until chocolate melts and forms a smooth sauce. If needed, add more cream in small amounts to achieve drizzling consistency. Let cool for a few minutes before drizzling over the caramel layer.

After drizzling the chocolate, sprinkle more sea salt over the top for the perfect sweet-salty balance. Allow the treats to cool completely before slicing into squares. For best results, chill slightly to properly set the caramel and chocolate layers.
