01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large mixing bowl, combine all-purpose flour, baking powder, and salt. Cut in cold, cubed butter using a pastry cutter or fingertips until the mixture resembles coarse crumbs.
03 - Stir in cold buttermilk just until incorporated. Do not overmix.
04 - Turn dough onto a lightly floured surface. Gently pat to about 1-inch thickness. Cut into rounds with a biscuit cutter. Place rounds onto prepared baking sheet. Bake for 12 to 15 minutes or until golden brown. Brush tops with melted butter.
05 - Pound chicken cutlets to even thickness if necessary. In a bowl, whisk together buttermilk and hot sauce. Add chicken, ensuring it is fully coated. Marinate for at least 20 minutes and up to 4 hours, refrigerated.
06 - In a shallow dish, combine flour, cornstarch, smoked paprika, garlic powder, salt, and black pepper.
07 - Heat approximately 1 inch of vegetable oil in a large skillet to 350°F. Remove chicken from marinade, allowing excess to drip off. Dredge thoroughly in flour mixture, shake off excess. Fry chicken cutlets for 3 to 4 minutes per side until golden and fully cooked. Transfer to a wire rack to drain.
08 - In a small saucepan over low heat, combine honey, hot sauce, and red pepper flakes. Warm for 2 to 3 minutes, stirring, until flavors infuse. Do not boil. Remove from heat and set aside.
09 - Carefully split warm biscuits. Place one piece of fried chicken inside each biscuit. Drizzle generously with hot honey. Add pickle slices if desired. Serve immediately.
