Place the flour on a flat surface and form a hole in the middle. Add the baking powder, the sugar, the salt, the butter, and the egg into the middle.
Slowly mix all of the ingredients by hand and form the hole in the middle again.
Slowly add the tea a little at a time as you knead the dough. The resulting dough will be sticky.
Continue kneading the dough until it is soft, smooth, and stretchy.
Take a ball of dough and put it on a floured surface, and then with a rolling pin, flatten it out. It should resemble a very thin tortilla.
Add oil to a pot or a deep fryer and heat to medium heat.
Fry each buñuelo for about 2 minutes on each side and remove from the oil immediately when cooked through. Coat each side with sugar.
Serve with piloncillo sauce or honey.
