How to make it

1. Heat oven to 350° F.
2. In large bowl, combine half the dry cake mix with butter, egg and vanilla; mix thoroughly with large spoon. Stir in remaining cake mix and oats; mix well.
3. Divide dough in half. On well-floured surface, using a well-floured rolling pin, roll each half to no more than 1/4-inch thickness. 
4. Cut dough with 3-inch snowflake or other large holiday cookie cutter. Place about 1-inch apart on ungreased cookie sheets. 
5. If cookies will be used as tree ornaments, poke a hole at the top of each cookie with drinking straw before baking. (Repeat immediately after baking if hole closes.)
6. Bake 6 to 8 minutes or just until set (centres may still be soft). Carefully remove to wire rack; cool completely. If desired, decorate cookies.
