Rhubarb Ginger Downside-Up Oatmeal Cake

April 25, 2010
Author Notes

All of my favorite things in one. Fresh ginger goes great with the rhubarb and the oatmeal cake, well, is gooey and tasty. Let it cool at least 20 minutes before slicing. I top it with frothed cream but vanilla ice cream would be great too. As for the name, I have to credit Vivian my 4-year-old. She corrected me when I said upside-down cake and said it should be a "downside-up" cake. - thirschfeld —thirschfeld

Test Kitchen Notes

This is a great cake. I was a little skeptical about the whole downside-up/upside-down "thing" since this is done in a cast-iron skillet, but the cake came out beautifully! The syrupy ginger-rhubarb topping is wonderful and the cake itself is moist and delicious. I brought this to a gathering and everyone raved -- the only problem was that I forgot to bring vanilla ice cream... I won't make that mistake again. - WinnieAb —The Editors
