01 - Preheat oven to 425°F. Line a baking sheet with parchment paper. In a large bowl, combine all-purpose flour, baking powder, and salt. Using a pastry blender or fingertips, cut in cold butter until mixture resembles coarse crumbs. Add cold buttermilk and mix just until dough comes together.
02 - Transfer dough to a floured surface and gently pat to a 1-inch thickness. Cut rounds using a biscuit cutter and arrange on the prepared baking sheet. Bake for 12 to 15 minutes or until golden brown. Brush tops with melted butter after baking.
03 - Pound chicken breasts to even thickness if necessary. In a bowl, combine buttermilk and hot sauce. Add chicken pieces and allow to marinate for 20 minutes at room temperature or up to 4 hours, covered, in the refrigerator.
04 - In a shallow bowl, mix together flour, cornstarch, smoked paprika, garlic powder, salt, and black pepper.
05 - Heat approximately 1 inch of vegetable oil in a large skillet to 350°F. Remove chicken from marinade, dredge in the flour mixture, and shake off excess. Fry chicken for 3 to 4 minutes per side until golden and cooked through. Transfer to a wire rack to drain.
06 - In a small saucepan, combine honey, hot sauce, and red pepper flakes. Warm gently over low heat for 2 to 3 minutes, stirring occasionally. Do not boil. Set aside.
07 - Split warm biscuits. Place one fried chicken cutlet in each biscuit. Drizzle with prepared hot honey. Add pickle slices if desired and serve immediately.
