01 - In a bowl, whisk together the buttermilk and hot sauce until combined. Submerge the chicken cutlets in the marinade, cover tightly, and refrigerate for at least 30 minutes or up to overnight for maximum tenderness and flavor penetration.
02 - Preheat oven to 450°F. In a large mixing bowl, whisk together the flour, baking powder, baking soda, sugar, and salt. Cut the cold cubed butter into the dry ingredients using a pastry blender or your fingers until the mixture resembles coarse crumbs. Pour in the cold buttermilk and fold gently just until the dough comes together—avoid overmixing to keep biscuits tender.
03 - Turn the dough out onto a lightly floured surface and gently pat it to a uniform 3/4-inch thickness. Using a 2.5-inch round cutter, cut out 8 biscuits by pressing straight down without twisting. Arrange on a parchment-lined baking sheet and bake for 12 to 14 minutes until the tops are golden brown. Brush the hot biscuits with melted butter as soon as they come out of the oven.
04 - In a small saucepan, combine the honey, hot sauce, and crushed red pepper flakes. Warm gently over low heat, stirring occasionally until well blended. Remove from heat and set aside.
05 - Pour vegetable oil to a depth of 1/2 inch in a large skillet and heat to 350°F. In a shallow dish, combine the flour, paprika, garlic powder, kosher salt, and black pepper. Remove each chicken cutlet from the buttermilk marinade, dredge thoroughly in the seasoned flour, and shake off any excess. Carefully lower the cutlets into the hot oil and fry for 3 to 4 minutes per side until deeply golden and cooked through to an internal temperature of 165°F. Transfer to a paper towel-lined plate to drain.
06 - Split each biscuit in half horizontally. Place a crispy fried chicken cutlet on the bottom half, drizzle generously with the warm hot honey, and add sliced pickles if desired. Cap with the biscuit top and serve immediately while hot.
