1. Preheat your oven to 375°F (190°C) and grease a baking dish or line it with parchment paper.
2. In a large mixing bowl, whisk together the flour, baking powder, and salt.
3. Add the shredded mozzarella and grated Parmesan cheese to the dry ingredients, mixing well to combine.
4. In a separate bowl, mix the melted butter and milk until fully combined.
5. Pour the wet ingredients into the dry mixture and stir until just combined. Do not overmix; a few lumps are perfectly okay!
6. If you’re using garlic powder, fold it in at this stage for an extra kick of flavor.
7. Transfer the mixture to your prepared baking dish, smoothing it out evenly.
8. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
9. Remove from the oven and let it cool for a few minutes before slicing. Garnish with fresh herbs if desired.

As you bake, let the aroma fill your kitchen—trust me, it’s heavenly and will make everyone gather around, eager for a taste!
