Heat oil in a deep fryer or large saucepan to 375 degrees F (190 degrees C).
Combine flour, baking powder, and salt in a large bowl; mix in milk to form a soft dough. Divide dough into eighteen 2-inch diameter balls; flatten or roll each ball into ½-inch-thick rounds. Make a small hole in the center of each round to help keep them flat while frying.
Lower dough rounds, about 3 or 4 at a time, carefully into hot oil. Fry until rounds have bubbles on the surface and are golden brown, about 2 to 3 minutes per side. Transfer to a paper towel-lined plate to drain. Repeat with remaining dough.
