Melt the Butter: In a small saucepan, melt the butter over medium heat.
Cook the Garlic: Add the minced garlic to the butter and sauté for 1-2 minutes until fragrant but not browned. Be careful, as burnt garlic can ruin the sauce.
Make the Sauce: Stir in the heavy cream and garlic powder (if using). Reduce the heat to low and let it simmer for 2-3 minutes, stirring occasionally to combine the flavors.
Add Parmesan Cheese: Gradually whisk in the Parmesan cheese until fully melted and the sauce is smooth and creamy.
Season: Add salt and pepper to taste, adjusting according to your preference.
Garnish and Serve: Remove from heat and sprinkle with fresh parsley if desired. Serve warm as a pizza dipping sauce or drizzle it directly onto pizza slices.
