1. 1. Prepare Your Pan: Lightly grease a 9×13 inch baking pan with butter or cooking spray. Alternatively, line it with parchment paper for easy removal.

2. 2. Melt the Butter: In a large non-stick pot or Dutch oven, melt the unsalted butter over low heat. Keep the heat low to prevent burning.

3. 3. Add Marshmallows: Add the mini marshmallows to the melted butter. Stir constantly until they are completely melted and smooth. Remove the pot from the heat immediately.

4. 4. Stir in Vanilla: Promptly stir in the vanilla extract. If using, add a pinch of salt now to enhance the flavors.

5. 5. Fold in Chips: Gently fold in the lightly crushed Ruffles Original Potato Chips. Mix until the chips are evenly coated with the marshmallow mixture. Work quickly, but gently.

6. 6. Press into Pan: Immediately transfer the mixture to your prepared baking pan. Using a buttered spatula or your buttered hands, gently press the mixture evenly into the pan. Avoid compacting it too firmly.

7. 7. Cool and Cut: Allow the Best Ruffles Krispy Treats to cool completely at room temperature for at least 1 hour before cutting into squares. Enjoy!
