Melt butter in a medium saucepan over medium heat.
Add minced garlic and sauté for 1-2 minutes until fragrant, stirring constantly. Don't let it brown.
Pour in heavy cream and whisk to combine. Bring to a gentle simmer and cook for 2-3 minutes.
Reduce heat to low and gradually add grated Parmesan cheese, whisking constantly until fully melted and smooth.
Add seasonings: garlic powder, onion powder, Italian seasoning, salt, black pepper, and white pepper. Whisk well.
Adjust consistency by adding milk or cream if too thick, or simmering longer if too thin.
Remove from heat and stir in fresh parsley if using.
Toss immediately with hot, crispy chicken wings, or store for later use.
