Pão de queijo (Brazilian Cheese Bread)

• ⅛  - nonstick cooking spray
• 1 cup - milk
• ¼ cup - extra virgin olive oil
• 1  - egg
• 260 Gram - tapioca flour
• ½ teaspoon - salt
• 2 Ounce - grated Parmesan cheese
• 2 Ounce - shredded mozzarella

Instructions

1. Preheat the oven to 400°F. Spray a 24-cavity mini muffin pan very liberally with nonstick cooking spray. Set aside.
2. Place the milk, olive oil, egg, tapioca flour, and salt in a blender. Process on high until smooth. Add the cheeses and pulse until incorporated, 4 to 5 times. (Pro Tip: A kitchen scale is highly recommended for this recipe, as tapioca flour is difficult to measure accurately in cups.)
3. Pour the mixture into cavities of muffin pan, filling each slightly more than half full.
4. Bake the pão de queijo on middle rack of oven until puffed and golden brown, about 20 minutes.
5. Check to see that pão de queijo is done. Remove from oven or add time as needed.
6. Allow pão de queijo to cool for 5 minutes, then use the tip of a sharp knife to remove from pan. Serve warm.
