01 - In a mixing bowl, whisk together the buttermilk and 1 teaspoon hot sauce until blended. Submerge the chicken cutlets in the marinade, cover tightly, and refrigerate for at least 30 minutes or up to overnight for maximum tenderness.
02 - Preheat the oven to 450°F. In a large bowl, whisk together the flour, baking powder, baking soda, sugar, and salt. Using a pastry cutter or your fingers, cut in the cold cubed butter until the mixture resembles coarse crumbs. Fold in the buttermilk, stirring gently just until the dough comes together—avoid overworking.
03 - Turn the dough out onto a lightly floured surface and pat it to 3/4-inch thickness. Using a 2.5-inch biscuit cutter, cut out 8 rounds and arrange them on a parchment-lined baking sheet. Bake for 12 to 14 minutes until the tops are golden brown. Immediately brush the hot biscuits with melted butter.
04 - In a small saucepan over low heat, gently warm the honey with 2 tablespoons hot sauce and the crushed red pepper flakes, stirring occasionally. Once warmed through and fragrant, remove from heat and set aside.
05 - Pour vegetable oil to a depth of 1/2 inch into a heavy-bottomed skillet and heat to 350°F. In a shallow dish, combine the flour, paprika, garlic powder, kosher salt, and black pepper. Remove the chicken from the buttermilk marinade, dredge each piece in the seasoned flour, and shake off any excess. Fry the cutlets for 3 to 4 minutes per side until deeply golden and cooked through to 165°F internally. Transfer to a paper towel–lined plate to drain.
06 - Split each biscuit in half. Layer a fried chicken cutlet onto 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.
