First, combine the ground chicken, salt, pepper, garlic powder, and smoky paprika in a large bowl. Mix everything together thoroughly with your hands or a spoon until the spices are evenly distributed throughout the meat. Place the bowl in the refrigerator to keep the chicken chilled while you prepare the breading.
Next, pour the corn flakes into a food processor and pulse them until they are broken down into coarse crumbs, similar in size to the panko. You don't want a fine powder, but you also don't want large flakes. Transfer the crushed corn flakes to a separate large, shallow bowl.
Add the panko breadcrumbs, salt, pepper, and smoky paprika to the bowl with the crushed corn flakes. Use a whisk or fork to mix all the breading ingredients together until they are well combined. This mixture will give your nuggets their signature crunch and flavor.
Lightly wet your hands to prevent the chicken from sticking. Scoop out about 1-inch balls of the chilled chicken mixture, similar to making meatballs. Gently flatten each ball into a classic nugget shape. Place each formed nugget directly into the breading mixture and toss to coat it completely on all sides. Set the coated nuggets on a baking sheet.
Heat a thin layer of avocado oil in a large skillet over medium-high heat. Once the oil is hot (after about 2-3 minutes), reduce the heat to medium. Carefully place the nuggets in the pan, ensuring you don't overcrowd it. Cook in batches of 7-8 nuggets at a time for about 3-4 minutes on the first side.
When the bottom of the nuggets is golden brown and crispy, flip them over. Continue to cook for another 3-4 minutes on the other side, or until the chicken is cooked through. The internal temperature should reach 165°F. Remove the cooked nuggets and place them on a wire rack to keep them crispy.
While the last batch of nuggets is cooking, melt the butter in a small saucepan over low heat. Whisk in the hot sauce until fully combined and heated through. Place all the cooked nuggets in a large bowl, pour the buffalo sauce over them, and toss gently to coat. Serve immediately with your favorite dipping sauces.
