Preheat oven to broil. Hollow out the inside of the baguette using a serrated knife to cut a wedge out from the top, and scoop out some of the bread. Place baguette on a baking sheet.
In a small saucepan, melt 4 tablespoons butter and 1 tablespoon chopped garlic over medium heat. Use a brush to coat the top and inside of the bread with the butter and garlic mixture. Sprinkle 3 tablespoons grated parmesan cheese over bread and broil until toasted, about 3-5 minutes. Set aside.
In a large skillet, melt remaining 6 tablespoons butter over medium heat. Stir in remaining garlic and cook until fragrant, about 1-2 minutes. Add a pinch of chili flakes and white wine and bring to a boil. Stir in shrimp and cream cheese and cook until cream cheese is melted and shrimp is cooked through, about 2 minutes. Season to taste with salt and pepper and pour into the bread.
Garnish with chopped parsley and a sprinkle of parmesan cheese.
