Preheat your oven to 400°F. In a large mixing bowl, combine goat cheese, cream cheese, mozzarella, Greek yogurt, and garlic. Mix until smooth and creamy, ensuring there are no lumps.
Transfer the cheese mixture to a greased 1-quart baking dish. Spread it evenly and bake for 20-25 minutes, until the edges are bubbling and golden. This step enhances the flavors and gives a luscious, melty texture.
Remove from the oven and spoon the bruschetta mix on top. Drizzle with balsamic glaze and sprinkle with fresh basil. Serve immediately for a warm, aromatic appetizer that looks as good as it tastes.
