I have made my own share of Upside Down Cakes (Cranberry and Mango-Raspberry Cakes) and I love each of them. Moist, buttery and sweet-tangy, these cakes truly posses the kind of flavors I look for in a cake. I thought I'd be happy with these two fruit versions already but then I thought I wonder if I could actually make a version using Kiwi fruits. To be honest, I have never eaten a Kiwi cake before so I wasn't sure if this will work at all. I have often used Kiwi for smoothies and just as a snack - raw - but I have never thought of actually baking with it.
