Pão de queijo with sweet potato

In a saucepan, boil the oil and milk together.

Once the mixture bubbles, pour it over the tapioca flour in a bowl.

Add the salt, sweet potato puree, and one egg to the bowl.

Start mixing the ingredients together with a whisk.

Add the Parmesan cheese and continue mixing with your hands until the dough is well combined.

Grease your hands with a little oil, take a portion of the dough, and flatten it in your palm.

Place a piece of mozzarella cheese in the center of the flattened dough.

Close the dough around the cheese, form it into a ball, and place it on a baking tray lined with parchment paper.

Bake in a preheated oven at 356°F (180°C) for 20 minutes.
