Grease an 8×8 inch baking pan with cooking spray or butter. Set aside.

In a large saucepan, melt the butter over low heat. Add the mini marshmallows to the saucepan and stir continuously until they are completely melted and smooth.

Remove the saucepan from heat and add in the Ruffles potato chips. Stir quickly and thoroughly until the chips are fully coated with the marshmallow mixture. It's okay to break the chips as you go to coat them better.

Transfer the mixture into the greased baking pan. Using a buttered spatula or your hands (lightly greased with butter or cooking spray), press the mixture into the pan. Top with sea salt for a more sweet and salty vibe.

Allow the Ruffles Chips Marshmallow Treats to cool and set at room temperature for about 30 minutes to an hour.

Once cooled and set, cut into squares or rectangles of your desired size.
