Preheat your oven to 350°F (175°C) and grease a 9x5-inch loaf pan.
In a large mixing bowl, whisk together the flour, baking powder, salt, and garlic powder until well combined.
Stir in the shredded mozzarella cheese, halved cherry tomatoes, and chopped basil until evenly distributed.
In a separate bowl, beat the eggs, then add the milk and olive oil, mixing until smooth.
Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix.
Transfer the batter into the prepared loaf pan and smooth the top with a spatula.
Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted in the center comes out clean.
Allow the bread to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
