Combine the all-purpose flour, sugar, salt, 1/4 cup of shortening, Nutri-oil, the brown egg, instant yeast, vanilla, and water in a mixing bowl and knead until you get a smooth and elastic dough.
Divide the dough into 2 portions and set aside.
Prepare a shortening mixture by mixing together 3/4 cup of shortening and the cake flour. Divide it into 2 portions.
Oil the table.
Roll out each portion of dough onto a lightly floured board.
Spread the shortening mixture onto the dough.
Fold the edges of the dough together to enclose the shortening mixture.
Put some oil on top of the dough and allow it to rest for 15-20 minutes.
Then, thinly roll out the dough on an oiled board and brush the surface with some more of the oil.
Roll tightly like a jelly roll (makes 2 rolls about 1 inch thick).
Brush the top of the dough again with some oil.
Allow the dough to rest for 10-15 minutes and then cut them crosswise to the desired portions. You'll probably want to make about 8 to 10 pieces from this amount of dough.
Brush the surface of each individual piece again with some of the oil and allow to rest for 10 minutes.
Now, roll out each portion and dip one side in sugar.
Transfer them to a greased baking sheet and bake in a 350°F oven for 10-12 minutes or until they're nice and crispy.
