Step 1: Marinate the Chicken - Slice the chicken breast into smaller pieces. In a bowl, combine the buttermilk, salt, and a pinch of pepper. Add the chicken pieces and let them marinate for at least 30 minutes.
Step 2: Prepare the Biscuit Dough - In a large mixing bowl, whisk together the flour, baking powder, sugar, and salt. Cut in the unsalted butter until the mixture resembles coarse crumbs. Pour in the milk and mix until just combined.
Step 3: Shape the Biscuits - Turn the dough out onto a lightly floured surface. Gently knead it a few times until it comes together. Roll out the dough to about 1-inch thick and use a biscuit cutter or glass to cut out rounds. Place on a baking sheet.
Step 4: Bake the Biscuits - Preheat your oven to 450°F (230°C). Bake the biscuits for about 12-15 minutes, or until golden brown.
Step 5: Make the Honey Butter - In a small bowl, mix together melted butter and honey until smooth. Set aside.
Step 6: Fry the Chicken - In a bowl, combine the flour, garlic powder, salt, and pepper. Remove the chicken from the marinade and coat in the flour mixture. Heat oil in a frying pan and fry the chicken for about 5-7 minutes on each side until golden brown.
Step 7: Assemble Your Biscuit - Slice a biscuit in half, place a piece of chicken on the bottom, drizzle with honey butter, and top with the other half.
