Use cooking spray or butter and grease bottom of a 13 x 9 cake pan. Mix all ingredients in medium bowl till smooth. Pour in cake pan. Bake at 350 degrees for 25-35 minutes or until tooth pick insert in middle comes out clean.
Either let cook and serve or serve warm. Try warming in microwave and spreading with butter or you can frost it with some cream chesse frosting. I prefer it cooled and plain.
