Step 1: Prepare the Chicken Nuggets

1. Season the Flour: In a shallow dish, mix the all-purpose flour with garlic powder, onion powder, smoked paprika, salt, and black pepper.
2. Set Up the Breading Station: In one shallow bowl, beat the eggs. In another, combine panko breadcrumbs and plain breadcrumbs.
3. Coat the Chicken: Dredge each chicken piece in the seasoned flour, dip it in the egg mixture, then coat it with the breadcrumb mixture. Press gently to ensure the breadcrumbs adhere well.
4. Heat the Oil: Heat vegetable oil in a deep skillet over medium-high heat until it reaches 350°F (175°C).
5. Fry the Nuggets: Fry the chicken pieces in batches, turning occasionally, for 3-4 minutes per side or until golden brown and cooked through. Transfer to a paper towel-lined plate to drain excess oil.

Step 2: Make the Waffle Batter

1. Mix the Dry Ingredients: In a medium bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
2. Combine the Wet Ingredients: In another bowl, whisk together the egg, buttermilk, melted butter, and vanilla extract.
3. Make the Batter: Gradually add the wet ingredients to the dry ingredients, whisking until smooth. Avoid overmixing.

Step 3: Coat and Cook the Nuggets

1. Dip the Nuggets: Heat a waffle iron or griddle to medium heat. Dip each cooked chicken nugget into the waffle batter, ensuring an even coating.
2. Cook the Nuggets: Place the coated nuggets in the waffle iron and cook for 3-5 minutes, or until the batter is golden brown and crispy. Repeat with the remaining nuggets.

Step 4: Prepare the Maple Drizzle

1. Combine Ingredients: In a small bowl, mix maple syrup, melted butter, and cinnamon (if using). Warm the mixture in the microwave for 20-30 seconds to enhance the flavors.

Step 5: Serve and Enjoy

1. Arrange the maple waffle chicken nuggets on a serving platter. Drizzle with the prepared maple syrup mixture and garnish with fresh parsley, if desired.
2. Serve warm with additional maple syrup on the side for dipping.
