1. Start by marinating the chicken pieces in buttermilk mixed with garlic powder, smoked paprika, cayenne pepper, salt, and black pepper. Cover and refrigerate for at least 30 minutes, or up to 4 hours. This step is key—it not only tenderizes the chicken but also infuses it with flavor.
2. While the chicken marinates, prepare your frying station. Heat vegetable oil in a deep skillet or Dutch oven to 350°F (175°C). Use a thermometer to maintain the temperature for crispy, golden results.
3. In a shallow bowl, whisk together the flour and baking powder. This combination helps create a light, crispy coating that I still remember my grandmother raving about.
4. Remove the chicken pieces from the buttermilk marinade, letting any excess drip off. Dredge each piece thoroughly in the flour mixture, pressing gently to adhere. For extra crunch, you can double-dip by returning the chicken to the buttermilk briefly, then back into the flour.
5. Carefully lower the coated chicken pieces into the hot oil, frying in batches to avoid overcrowding. Fry for about 4-5 minutes, turning occasionally, until golden brown and cooked through (internal temperature should reach 165°F/74°C).
6. Transfer fried chicken to a wire rack set over a baking sheet to drain excess oil while you finish frying the remaining pieces.
7. To assemble, spread mayonnaise or your preferred sauce on the bottom half of each toasted slider bun. Layer on a piece of fried chicken, top with a couple of dill pickle slices, and add fresh lettuce if you like that extra crunch.
8. Top with the bun crown and press gently. Serve immediately for the best texture and flavor.

Quick tip from my kitchen: keeping the fried chicken warm in a low oven (around 200°F) while you finish frying makes assembling the sliders much easier and ensures everyone gets hot, crispy bites.
