Don’t let the simplicity of this kumquat upside down cake fool you. The candied kumquats nestled into the cake creates incredibly moist and delicious dessert.

I adore fruits. Maybe it’s my Persian heritage, but fruits are a HUGE part of our diet. It’s no wonder that a fruit bowl is always present in the Persian household. They are nutritious and so incredibly full wonderous flavors and textures.

So it’s not a surprise that I love featuring my favorite fruits in my desserts. Don’t get me wrong, I love chocolate, but pass me a fruit pie or fruit cake any day of the week. And my current fruit obsession? The kumquat!

Do you eat the skin of a kumquat?

Kumquats seem to confuse people. They look like oranges in their bright orange peels, but are the size of a large olive. Whenever I introduce kumquats to friends, they look at it sitting in their hands and ask how to eat it?

Do I peel it? Aren’t they bad? They are too sour! Kumquats stand out in the citrus family because the entire fruit, skin and all, is edible. The kumquat skin is deliciously sweet while the fruit and juice inside is tart. It makes an incredible combination in your mouth!

Kumquats do have seeds and they are edible. But, I personally, do not like the large seeds and do not eat them. When cooking or baking with kumquats, I usually remove all seeds first.

What are kumquats used for?

So if you are new to the wonderful world of the kumquat, you are probably wondering what other ways you can enjoy this beautiful fruit. I have made kumquat marmalade, cardamom kumquat bars and even kumquat margaritas.

If you can think of a recipe using oranges or lemons, then you can easily follow the same recipe using kumquats. Since I love upside down cakes, especially my Valencia orange upside down cake, it was only natural for me to make a kumquat upside down cake.

How to make a kumquat upside down cake

My favorite pan to bake my upside down cakes is the cast iron skillet. Since you need to melt the butter and caramelize the brown sugar, the cast iron pan is perfect for stove top cooking and baking. I like to make a nice syrup before adding the fruit on the bottom of the pan.

For the kumquats, I halve each kumquat, cutting the large ones in thirds and then arranging them along the bottom of the pan with the buttery brown syrup. For my 9-inch skillet, I used 20 kumquats. You could totally squeeze in more.

I also finely chopped kumquats and added them to the cake batter, continuing the delicious citrus flavor throughout the cake. Once the kumquats are lining the bottom of your skillet, gently pour in the batter and bake it in the oven for about 30 minutes.

I let the cake cool for about 10-15 minutes before I flip the cake out of the pan. You need to invert the cake after it’s baked while it’s still warm. If the cake is completely cooled when you flip it over, the kumquats will stick to the pan.
