Quick Brazilian Cheese Rolls {Pao de Queijo}

1 large egg
1/2 cup milk
1/4 cup canola oil
1 cup tapioca flour (sometimes labeled tapioca starch) no substitutions
1/2 tsp kosher salt
1/4 C grated cheddar cheese* (preferably medium or sharp)
1/4 C grated Parmesan cheese


Optional:  extra cheese to sprinkle on top and any herbs/flavorings you’d like to add.  Try rosemary and or garlic powder.
Preheat oven to 400 degrees.  Place egg, milk, oil, tapioca flour, and salt in blender and blend until smooth.  Add cheeses and pulse 2 times.  Immediately pour batter into a greased mini muffin tin, filling each well about 3/4 full, or just slightly less.  If desired  sprinkle a bit of parmesan cheese on top and/or a tiny sprinkle of kosher salt.
Bake for 15-20 minutes until puffed and golden.  Remove from oven and cool for a few minutes before removing rolls from pan.  Serve warm.
