In a large mixing bowl, combine 2 cups of all-purpose flour, 1 tablespoon of baking powder, 1 teaspoon of minced garlic, 1 teaspoon of Italian seasoning, and ½ teaspoon of salt. Use a pastry cutter to cut in ½ cup of cold salted butter until the mixture resembles coarse crumbs. In a separate bowl, whisk together 1 large egg and ½ cup of milk. Pour the wet ingredients into the dry mixture and stir until a dough forms.

Transfer the dough onto a floured surface. Using a rolling pin, roll it out to approximately ¼ inch thick, ensuring an even thickness throughout.

Using a round cookie cutter or a glass, cut the rolled dough into circles. Place a spoonful of pizza sauce, a generous amount of shredded mozzarella cheese, and your choice of pepperoni and cooked Italian sausage in the center of each circle.

Fold each dough circle in half over the filling, creating a semi-circle. Press the edges firmly to seal.

Preheat your oven to 400°F (200°C) while you prepare the baking sheet. Line a baking sheet with parchment paper. Place the prepared pizza pockets on the sheet, brush the tops lightly with melted butter, and then bake in the oven for 20-25 minutes.

Once baked, remove the pizza pockets from the oven and let them cool on the baking sheet for a few minutes. Serve warm alongside extra pizza sauce or marinara for dipping.
