In a large bowl, combine flour, baking powder and salt. Cut in shortening until mixture resembles fine crumbs. Gradually add water, tossing with a fork until a loose ball forms (dough will be crumbly).
On a lightly floured surface, knead the dough for 3 minutes or until smooth. Cover and let rest for 10 minutes. Roll out into a 12x10-in. rectangle. Cut into 12 square shapes with a knife or cut into 12 circles using a round biscuit cutter.
In a deep-fat fryer, heat 2 in. oil to 375°. Fry sopaipillas for 1-2 minutes on each side. Drain on paper towels; keep warm. If desired, dust with confectioners' sugar and/or serve with honey.
