In a small bowl, combine the cherry tomatoes, minced garlic, olive oil, balsamic vinegar, salt, and fresh basil. Gently mix and set aside to allow the flavors to meld.
In a separate bowl, add the softened cream cheese, chopped prosciutto, sun-dried tomatoes, dried basil, garlic powder, salt, and pepper. Mix until smooth and evenly combined.
Place a 4-inch ring mold on a serving plate and firmly pack the cream cheese mixture inside, smoothing the top with a spoon or spatula.
Transfer to the refrigerator and chill for about 15 minutes, just until set.
Carefully remove the ring mold. Spoon the tomato bruschetta mixture over the top, allowing some juices to naturally drip down the sides.
Finish with fresh basil leaves and serve immediately.
