Prepare Suya Seasoning: Gather all dry spices, peanut powder, ginger powder, cayenne pepper, paprika, smoked paprika, onion powder, garlic powder, chicken bouillon powder and mix in bowl. Store in container until you are ready to make chicken wings.
If using roasted peanuts, pulse in a food processor and be careful not to pulse too long or it will turn into peanut butter. Add other spices to food processor and pulse until well mixed and store until you are ready to make chicken wings.
Make Chicken Wings: Using a paper towel, dry your chicken wings and place in a large bowl.
Add baking powder, cornstarch and salt to chicken and toss thoroughly until chicken wings are completely coated.
Place on a baking rack (baking sheet below and elevated metal rack on top) and arrange neatly and spaced apart so the wings are not touching.
Use two racks if you have to.
Place your rack of coated chicken wings in the fridge uncovered for 6-8 hours. And up to 24 hours. I prefer leaving them in the fridge for 24 hours for dry them out.
When ready to bake wings, preheat the oven to 450 degrees fahrenheit.
After the wings have dried out in the fridge, place a baking sheet with wings in the oven on the upper middle rack, cook for 20 minutes, and flip and cook for an additional 15 minutes.
In the meantime, place your butter in the microwave for about 30 seconds until fully melted.
Coat Chicken Wings: After 35 minutes in the oven, remove chicken wings, place in a large bowl and pour melted butter as well as desired amount of suya seasoning on wings and toss until coated.
Arrange your coated wings on your rack again and bake for an additional 15-20 minutes.
Take wings out of the oven, and serve on a platter. Optional but if you want to balance the fattiness of the wings, butter and peanuts in the suya, squeeze some lime juice over the wings right before serving.
