Prepare Your Dish: Start by greasing a 9×13-inch glass baking dish with non-stick cooking spray and set it aside, ensuring your bars won’t stick.

Melt Marshmallows and Butter: In a large microwave-safe bowl, combine the butter and mini marshmallows. Microwave on high for approximately 1 minute and 15 seconds until the marshmallows are melted and fluffy. Stir the mixture until smooth.

Mix in Rice Krispies: Add the Rice Krispies cereal to the melted marshmallow mixture, stirring until well combined. Transfer the mixture to the prepared baking dish and press it evenly into the pan to create a solid base for your bars.

Prepare Caramel Sauce: In a medium microwave-safe bowl, combine the unwrapped caramels and milk. Microwave on high for 1 minute and 20 seconds, stirring occasionally, until the caramel is smooth and fully melted. If needed, continue microwaving in 10-second intervals until desired consistency is reached.

Drizzle with Caramel and Salt: Pour the melted caramel sauce over the Rice Krispies mixture, ensuring even coverage. Sprinkle a generous amount of coarse sea salt over the caramel layer to add a delightful contrast of flavors.

Allow to Set and Serve: Let the bars sit at room temperature for approximately 15 minutes to allow the caramel to set. Once firm, cut the bars into 16 individual servings and indulge in the ultimate sweet and salty treat!
