Blend butter and sugar thoroughly. Add the egg and blend thoroughly. Add OJ and blend thoroughly. Add flour, ½ cup at a time, alternating white and wheat, blending thoroughly between each. Add the baking powder and cinnamon with the last half cup of flour. Refrigerate batter overnight or at least a few hours. 2. Roll as thin as you can without getting holes in the batter (for best results, roll between two sheets of wax paper lightly dusted with flour). Cut out 2 or 3 inch circles.
Put a dollop of filling in the middle of each circle. fold up the sides to make a triangle, folding the last corner under the starting point so that each side has corner that folds over and a corner that folds under. 4. Bake at 350 for about 15-20 minutes, until golden brown but before filling boils over.
