                    CORN-FLAKE COOKIES

2 tablespoonfuls of margarin   ¼ cupful coconut
½ cupful sugar                       ¾ cupful rolled oats
2 eggs                                    4 cupfuls corn flakes

Cream together the margarin and the sugar, add the eggs well
beaten, and the rest of the ingredients.  Drop by spoonfuls
on a greased baking-sheet or the bottom of a cake pan.  Bake
about fifteen minutes in a 400° F. oven.  Let stand on the
pan a few minutes, after removing from the oven, until they
harden.

[note: A similar recipe in Every Woman's Cook Book (1926) is flavored with lemon extract or vanilla.]
