Butter Melting: In a sizable saucepan, set over medium-low heat, melt the unsalted butter until it turns into a clear liquid.

Marshmallow Integration: Introduce the miniature marshmallows into the saucepan, ensuring continuous stirring. Allow the marshmallows to melt entirely, forming a uniform mixture.

Vanilla Infusion: Once the marshmallow mixture is smooth, remove the saucepan from the heat. Proceed to stir in the pure vanilla extract, ensuring even distribution.

Potato Chip Incorporation: Gradually fold in the crushed ruffled potato chips. Ensure the chips are completely enveloped in the marshmallow mixture.

Preparation for Setting: Transfer the combined mixture to a greased 9x9-inch baking dish. Using a spatula or the back of a spoon, press down on the mixture to create a flat, even layer.

Cooling and Setting: Allow the mixture to cool down to room temperature. Once set, utilize a sharp knife to cut the mixture into precise squares. Serve appropriately.
