Sift flour into a large bowl.

Add salt, sugar, and baking powder to the flour and mix well.

Cut in shortening using a pastry blender or your fingers until the mixture resembles coarse crumbs.

Dissolve dry yeast in warm water.

Scald the milk and let it cool slightly until lukewarm.

Add the yeast mixture to the cooled milk.

Make a well in the center of the dry ingredients.

Pour the liquid ingredients into the well and gradually mix to form a dough.

Knead the dough on a lightly floured surface for 15-20 times until it becomes smooth and elastic.

Cover the dough and let it rest for 10 minutes.

Roll out the dough to 1/4 inch thickness.

Cut the dough into squares or triangles.

Heat oil in a deep fryer to 420°F (215°C).

Carefully drop 2 sopaipillas at a time into the hot oil.

Fry until golden brown and puffed up, about 1-2 minutes per side.

Remove the sopaipillas from the oil and drain on paper towels.

Serve hot with honey, powdered sugar, or your favorite toppings.
