In a large mixing bowl combine the flour. salt, baking powder, and sugar. Mix the dry ingredients together well.
Add the softened butter and gently mix together.
Slowly pour about 1/4th to 1/2 cup of water in at a time and knead as you pour. Keep doing this until the ingredients combine into a ball of dough that isn't overly sticky.
In a large frying pan heat the vegetable oil on medium heat.
While the oil heats tear pieces of the dough off and roll into about 2 inch sized balls.
When they're semi-smooth pat them flat until they're about an inch or so thick. Put on a plate and cut two slits on top with a sharp knife. Repeat these steps until all of the dough is gone.
Use a pair of tongs to place 5-6 dumplings in the hot oil. Fry on each side for about 3-5 minutes or until golden brown. This will vary based on how hot your oil in the pan is.
Line a plate with paper towel and place the finished fried dumplings on it as you take them out of the oil.
Repeat these steps until all of the dumplings are fried. Let them cool off for a few minutes and enjoy!
