In a frying pot (I use a 2.5 quart dutch oven) add the vegetable oil and heat over medium heat until it reaches 350 Farenheit or 175 celsius
In a bowl mix the corn starch, cassava flour, sugar and baking powder. Whisk until well combined
Add the cheese and mix well
Add the egg and milk and start kneading the dough until a smooth play dough-like consistency is achieved
Form small round balls, about 1.5 inches in diameter r about 30 grams each
Add them to the frying oil, making sure the oil conserves the temperature. If the oil starts getting hotter than 350 farenheit, reduce the heat until it is the desired temperature
Fry the buñuelos for about 6 minutes, until golden brown
Remove from the oil and place them on a plate with a paper towel to drain excess oil
Allow them to cool down for about 10 minutes
