01 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together flour, baking powder, baking soda, salt, and sugar until well combined.
03 - Add cold cubed butter to the flour mixture. Use a pastry cutter or fork to work butter into flour until mixture resembles coarse crumbs with some pea-sized butter pieces remaining.
04 - Pour cold buttermilk into flour mixture. Stir gently with a spatula until dough just comes together. Do not overmix.
05 - Turn dough onto a lightly floured surface. Gently pat dough to 1-inch thickness. Cut out 8 rounds using a 2.5-inch biscuit cutter, pressing straight down without twisting.
06 - Place biscuits on prepared baking sheet. Brush tops with buttermilk. Bake 12 to 15 minutes until golden brown. Let cool slightly on wire rack.
07 - Slice each chicken breast horizontally to create 4 thin cutlets. Place in a shallow dish.
08 - Whisk together buttermilk and hot sauce. Pour over chicken pieces. Let marinate at room temperature for 20 minutes.
09 - In a separate bowl, combine flour, cornstarch, paprika, garlic powder, salt, and black pepper. Mix thoroughly.
10 - Pour vegetable oil into a deep skillet or Dutch oven to reach 2 inches depth. Heat oil to 350°F.
11 - Remove chicken from marinade, allowing excess to drip off. Press each piece firmly into flour mixture, coating completely on all sides.
12 - Carefully place chicken in hot oil. Fry 4 to 5 minutes per side until golden brown and internal temperature reaches 165°F. Transfer to paper towel-lined plate to drain.
13 - Combine honey, hot sauce, and crushed red pepper flakes in a small saucepan. Warm over low heat 2 to 3 minutes, stirring constantly until fully blended. Remove from heat.
14 - Split each biscuit in half horizontally. Place fried chicken on bottom biscuit half. Drizzle generously with hot honey. Top with remaining biscuit half. Serve immediately.
