01 - Using a mandoline slicer or a sharp knife, cut the scrubbed 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 crisp frying.
03 - Pour vegetable oil into a deep fryer or a large heavy-bottomed pot and bring it to 350°F (175°C). Use a thermometer to maintain consistent temperature.
04 - Carefully lower potato slices into the hot oil in small batches to avoid crowding. Fry each batch for 3 to 4 minutes until golden brown and crisp. Remove with a slotted spoon and drain on paper towels.
05 - In a small saucepan, melt the unsalted 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, ensuring an even coating across all chips.
07 - Drizzle the prepared Buffalo sauce over the seasoned chips and toss gently until every chip is evenly coated with the spicy butter mixture.
08 - Transfer the Buffalo chips to a serving platter and garnish with blue cheese crumbles or a drizzle of ranch dressing and chopped fresh chives or green onions if desired. Serve immediately while hot and crisp.
