Preheat Oven: Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Heat Wet Ingredients: In a medium saucepan, combine the milk, vegetable oil, and salt. Heat over medium heat until it just starts to boil. Remove from heat.
Mix in Tapioca Flour: Gradually add the tapioca flour to the hot liquid, stirring constantly with a wooden spoon until the dough becomes thick and sticky.
Cool Slightly: Let the mixture cool for a few minutes, so it’s not too hot to touch.
Incorporate Cheese and Eggs: Add the Parmesan and mozzarella cheeses to the dough and mix well. Then, add the eggs one at a time, mixing until fully incorporated. The dough will be sticky and stretchy.
Shape Dough: Use a spoon or your hands (lightly oiled or wet) to form 1-inch balls of dough and place them on the prepared baking sheet.
Bake: Bake for 20-25 minutes or until the cheese bread balls are puffed up and golden on top.
Serve: Enjoy warm as a snack or side dish. They’re perfect with coffee or tea!
