WONDERFUL! I made this recipe just as written and loved it! I'm a big fan of root vegtables and Rutabaga's top the list. My friends asked for seconds after dinner. It was a big hit. You can also used leftover mashed Rutabaga's instead of the raw. Nice way to use it up. Although i rarely have much leftover. ENJOY!
I had no idea what to do with the rutabaga in my box of produce, so I made this for a group gathering. Everyone loved it, and no one could determine the "secret" ingredient. The only thing I would do differently would be to add the glaze just before serving. I put it on the night before, and it completely soaks into the cake, making it look (and taste) unfrosted.
