March is tricky. It’ll throw out a few of those luxuriously warm days in a row, which cause collective memory loss about the fact that it’s still winter, and you’ll suddenly see a few dazed people out on the street wearing shorts. And then it gets cold again, and it might even snow soon, and the warm coat you so optimistically tucked away into your closet has to come back out. By this time, you might also be really tired of root vegetables and stews, and all things earthy and hearty. I am. Thankfully, there is citrus. Bright, sweet, lush, like little suns in fruit form. I’m continually amazed by the variety of citrus fruit available at the grocery store this time of year. Based on my last scan of the citrus section, there are at least three types of oranges, the blood variety being the star, about as many kinds of grapefruits (red, pink, white), and don’t even get me started on the numerous hybrids, smooth-skinned, wrinkled and everything in between. I wanted to make a treat that really captures that brightness and abundance, so an upside down cake was in order. It looks involved to those not in the know, but it’s actually the easiest kind of cake to make.


For the cake itself, I wanted a batter that would come out of the oven moist and fluffy, and I aimed for gluten-free and vegan, since that is what most of you guys seem to enjoy. There was a large jar of polenta in my pantry – there always is, since my eight year old is a polenta fiend – and I had the idea to go the corncake route. I’m really happy I did, and the cake was gone within a day as proof of its success. It’s sweetened with dates, apple sauce and orange juice, so nothing too sugary here. The mellow sweetness and crumbly texture of the cake combines really well with the fragrant, bright notes of the blanket of citrus on top. I like keeping the skin on the citrus slices, since its oils contribute lovely, complex notes to the overall flavor, but if you or your kids are not fond of a little bitterness, you can cut the skin off the slices.


One of the main challenges of vegan baking is coming up with the correct combination of ingredients for a moist batter that doesn’t fall apart, without eggs. I’ve found apple sauce to be the essential ‘secret’ ingredient that makes all of the above possible, while adding a bit of its subtle sweetness to the mix. It also seamlessly integrates into sweet baked goods, so you won’t be tasting apple sauce in the finished product. Plus, it’s a healthy, clean, plant-based ingredient, and we all love those here. I was excited to work with North Coast on this recipe, since their apple sauce is the best I’ve ever tasted and contains no preservatives and no added sugar, all the while being made with real, organic, non-GMO ingredients. Their sauce tastes incredibly fresh and crisp, and they offer well-considered flavor options, like plain, berry, apricot, pumpkin spice and more, made with all U.S. grown fruit. Besides this cake, I’ve been using North Coast apple sauce in so much of my cooking lately, from these brownies, to my morning oats, atop a cup of coconut yogurt and even in smoothies. The brand also offers apple cider vinegar, cider and juice, so there is a definite mastery of wholesome apple products, which I absolutely love.



- 1 cup non-GMO polenta
- 1 cup brown rice flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- sea salt
- zest of 2 organic oranges
- 10-12 soft Medjool dates - pitted and soaked in warm water for 10 minutes, soaking liquid reserved
- 1 cup freshly squeezed orange juice
- ⅓ cup apple sauce
- 2 tablespoons coconut oil, plus more for oiling the pan
- 1 tablespoon apple cider vinegar
- 2-3 oranges - sliced ½-inch thick (You can use a variety of different kinds for a more colorful presentation. I used navel, cara cara and blood oranges.)
- Preheat oven to 375° F (190° C). Cut out a parchment paper circle to cover the bottom of a 9-inch spring form or cake pan. Thoroughly oil the sides of the pan with coconut oil.
- In a large bowl, combine the polenta, brown rice flour, baking soda, baking powder, a pinch of salt, and orange zest, and mix thoroughly.
- Reserve ½ cup of the date soaking water and add it to an upright blender along with the dates and orange juice, blend until smooth. Add the apple sauce, coconut oil and apple cider vinegar and pulse to combine.
- Pour the wet mixture into the bowl with the dry ingredients and stir to just combine.
- Arrange the orange slices to cover the parchment paper-lined bottom of your pan and pour the batter over them. Even the batter out with a spoon. Lift and drop the pan gently a couple of times to get rid of any possible air bubbles.
- Bake for 40-45 minutes, or until an inserted toothpick comes out clean. Let cool for at least 20 minutes before inverting the cake onto a plate or a cake stand and peeling off the parchment paper. Slice and serve with plain yogurt or coconut yogurt.
This cake looks like sunshine. I’m all for celebrating the last dredges of winter, if only for the beautiful citrus.
Thank you :)
Such a beautiful cake! I’m getting ready to make a blood orange cake myself today. There is nothing like those pretty pieces of citrus on the top!
So true :)
I’m making this today, sounds delicious. Brings back tons of memories since my husband and I lived in Sebastopol for many years and had an organic Gravenstein apple orchard and we sold our apples to Solana Gold and they used them for apple sauce. It was also sad to see so many orchards ripped out for grapes, which inevitably sucked up tons of water. Most of the apple orchards were dry farmed
Hi Cheri, hope it turned out well! Didn’t know that about grape vs apple orchards, very interesting.
I live near Sebastopol now and the apples are making a come-back. Local craft cider makers are using the old varieties so, there is hope for an apple renaissance.
A great time to visit is in August when the local Farm Trails co-op hosts the annual Gravenstein Apple Fair at Ragle Park in Sebastopol.
The orange upside down cake is gorgeous, thanks for sharing this. I may start baking again with this recipe and I have two Blood Oranges left from my annual harvest, a fitting tribute to my favorite fruit.
Usually, I eat one orange a day as dessert to really savor them and make them last. They are regal fruits, all.
Wow, this looks perfect and so so healthy!!! I need to try it asap :D
Thank you Valentina :)
How delicious this cake sounds and looks, can’t wait to try it! It reminds me of my grandma’s polenta cake, with smetana and sunflower oil. Thank you, Anya!
Your grandma’s cake sounds so good Natalia!
Very practical and easy to do, I did not know it was that simple, I’m sure to do.
Hi Ana, Yes! They look so impressive but so easy to make :D
My polenta probably should be thrown out it’s so old but I will gladly buy more to make this beautiful cake.
I made this cake last weekend and enjoyed it all week. It was sooo tasty and yummy. We even melted some chocolate to add as frosting last night…it reminded me of chocolate orange truffles I used to eat. I am looking forward to making it again :D
Hi Millie, SO happy to hear that :D The chocolate ‘frosting’ sounds perfect.
Thank you Anya!
I never made a polenta cake before. Tried it two times, with oranges und with apples and cinnamon. Great recipe and impressive presentation with blood oranges, my guests loved it!
So happy you enjoyed it Yvonne, thank you for letting me know :)
This is fantastic! Not only tasty but so quick and easy to make.
Very Nice Article…
Could you sub the rice flour for coconut flour or would that ruin the texture?
Also, what is the drink you have pictured in the photos?
Hi Brooke,
Coconut flour is tricky, I don’t think it would work here. The cake would become too dense and dry. The drink is just water that I infused with freshly sliced strawberries for a day or two!
Could you substitute the rice flour with Almond flour or Oat flour? Also, do you think this will work with Lemons instead of Oranges but leaving out the slices on the bottom of the tin.
Hi,
I can’t say for sure about the flour, as I haven’t tried these substitutions myself, but I think it might work. The lemon will work. The cake might be a little plain without the citrus slices, but if you serve it with ice cream, yogurt, or some kind of frosting, it’ll be great :)
Will try it with lemon and almond flour and update the results.
Great, please let me know how it works out!
Made this and turned out great! Replaced orange completely with lemons – put in zest of about 3-4 lemons cos they are smaller and 1 cup of lemon juice. Really great and lemony!
So happy it worked out! Thank you for letting me know :)
I made this cake for the NY eve and it turned out perfectly! Ii is also so easy to make with just a few ingredients. I added some poppy seeds to the batter. Anya, that would be great if you share some recipes with the poppy seeds. Thank you for your work.
So glad you enjoyed it! Poppy seeds sound like an amazing addition, and thank you for the idea! Will keep poppy seeds in mind for future desserts :)
Interesting Cake made with Citrus fruits, I want to try it, Does actually taste good though I want know before I make it at home ?
I’ve been thinking to make it for three months and I’ve only made it now. I so should’ve made it before as it absolutely delicious! :) Not too sweet, perfectly bitter from the citrus peels, it’s moist and the citrus slices taste fantastic (I cut them rather thin as I wasn’t sure how they will work out, next time I will make them thicker). Thank you Anya for this one. Constantly impressed by your delicious inventions!
YAY! So glad you enjoyed it Ula :)
