If you want to be surprised by a dessert, make plans to make this Kumquat Upside Down Cake this week. This is quickly becoming a favorite dessert here.
Alright y'all! let's talk about the third recipe I am sharing with you for Spring Sweets Week.
When I decided to make a Kumquat Upside Down Cake, I had no idea what this was going to taste like. I have never baked or cooked anything involving Kumquat, so when I got my box of produce from Melissa's produce and saw there was a bag of Kumquats, I knew I was going to find something fun to make for y'all.
I cracked one open right away so that I could taste it and they are VERY sour — like a mix between a lime, lemon, and an orange.
But, when you mix these little beauties with some sugar, you get an explosion of delicious dessert flavor in your mouth.
How to Make a Kumquat Upside Down Cake
Start by slicing up all of your kumquats. You are going to want about 2 cups of whole kumquats, and then slice them about 1/4″ thick. Be sure to remove all the seeds from the slices.
Now, melt your butter in your 8×8 baking dish and then sprinkle on the brown sugar.
Take the kumquat slices and place in the bottom of the pan in a single layer.
Then, make your cake batter. I love making homemade cakes — to me, they taste so much better than store bought. However, if you do use a boxed cake mix, you can totally make a boxed cake taste like a bakery cake using these tips.
I always make sure to flavor my cakes with extract and for this one, I am using a Vanilla bean paste from Taylor & Colledge.
Once the batter gets all mixed up, pour it right over the kumquats and smooth out and then leave it alone!
When you take the cake out of the oven, let it rest for about 15 minutes. Place a plate on top of your pan and invert it so the cake falls out onto the plate.
It should slide right out and everything stay intact.
The bright citrus flavor of those kumquats really makes this delicious upside-down cake tastes amazing and just really reminds me of Spring.

Love this! Substituted 1 C solid coconut oil for the 1 C butter and used lactose free milk due to our dairy intolerance. Came out even more delicious than I imagined. And the incredible smell as it was cooling wafted through the house. Thank you!

Sounded delicious and I suck at baking so it seemed like an easy effort for me. The 1 cup of milk threw me though. I assumed it was supposed to go in after the butter and sugar were creamed but didn’t know so I went for it. Fingers crossed I didn’t blow it.
