01 - Using a mandoline slicer or sharp knife, cut the potatoes into thin, even slices approximately 1/8 inch thick.
02 - Submerge the potato slices in a bowl of cold water for 10 minutes to draw out excess starch. Drain thoroughly and pat each slice completely dry with paper towels to ensure maximum crispness during frying.
03 - Pour vegetable oil into a deep fryer or large heavy-bottomed pot and heat to 350°F (175°C). Use a thermometer to monitor the temperature for consistent results.
04 - Working in small batches to avoid overcrowding, carefully lower potato slices into the hot oil. Fry for 3 to 4 minutes per batch until golden brown and crisp. Remove with a slotted spoon and drain on a paper towel-lined plate.
05 - In a small saucepan, melt the butter over low heat. Pour in the hot sauce and whisk continuously until the mixture is smooth, well blended, and heated through.
06 - While the chips are still warm, toss them with garlic powder, smoked paprika, salt, black pepper, and cayenne pepper if using. Ensure each chip is evenly coated with the seasoning blend.
07 - Drizzle the prepared Buffalo sauce over the seasoned chips and toss gently until every chip is evenly coated with the spicy, buttery sauce.
08 - Transfer the chips to a serving platter immediately. Top with blue cheese crumbles or a drizzle of ranch dressing and scatter fresh chopped chives or green onions over the top, if desired. Serve warm.
