Add the flour, cornmeal, baking powder, salt, and sugar to a mixing bowl and combine these dry ingredients well.
Gradually pour the milk into the dry ingredients and knead until you form a soft dough. (A soft dough but not paste-like).
Add enough oil to a deep frying pan and heat on medium to low fire.
Divide the dough into smaller portions (about 10-12 pieces) and roll it in the palm of your hands to form it into an oval-like shape.
Place the dough one at a time into the heated oil. Constantly turn dumplings so that it cooks on all sides.
Once the dumplings get golden brown, remove from the oil.
Notes
You can use whatever milk you like for the recipe. I used unsweetened oat milk.
Not all flour is made equal, and the amount of milk you need will change with each brand of flour. You may need more or less milk than given in the recipe.
