When I "graduated" from elementary school, our principal made a speech stating that by the time we young'uns made it into the work force, 50% of jobs would require the use of a computer. I assumed I would never fall into this category. The only thing computers were good for was playing Crystal Quest. I would never be caught dead working on a computer.
Imagine my chagrin to find myself, 20 years later, the proud mama of an almost-three-year-old blog as my full time "job." (And I mean "job" not in the getting paid sense of the word, but rather that which takes up much of my energy.) Do I wish I'd taken a programming course or two instead of wasting my expensive college education on a less-than-useless art history degree? Why, yes I do.
Luckily, I have bojon friends like Jocelyn, an early-retired techie who finds picking through Blogger's CSS code "fun" and is willing to do so in exchange for gluten- and cow's milk-free baked goods. She is my hero.
You may have noticed some of Jocelyn's cosmetic changes to this site in the past week (and there will be more to come!) My first payment installment was a batch of chocolaty, rummy Congo Bars; the second is this cake. Both are gluten-free and, except for the butter, dairy-free.
The recipe hails from Everyday Greens, one of the first cookbooks I bought for myself from the UCSC bookstore. When I should have been memorizing dates that I would instantly forget after I got my diploma, I was baking brown butter plum cakes, maple spice muffins, and this superb upside-down cake.
Fresh nectarines (and I added plums) nestle into a brandy and brown sugar caramel. A silky batter comprised of lots of butter and almond paste tops the fruit. The abundance of eggs and almond paste make this cake easy to de-glutenize; the result is absolutely indistinguishable from the original. People will think you are lying when you tell them that this cake contains neither gluten nor any starches or gums, but it is the case.
You might expect a cake like this to be dense and heavy; not so. I used a combination of sticky rice and oat flours, and it baked up into the fluffiest, moistest upside-down cake I've ever eaten. The slightly floral almond flavor, which is distinct yet soft, complements the stone fruit, which are in the almond family, as evidenced by their almond-esque pits.
I like this cake even better the second day, when the cake has absorbed even more of the caramel and juices, though it is prettiest on the first. Feel free to trade the plums and nectarines for peaches, apricots or cherries, or even ripe pears. Serve it with a spot of crème fraîche or softly whipped cream if you like.

(Gluten-Free) Nectarine Plum Almond Upside-Down Cake
Print Recipe Pin RecipeIngredients
The Topping:
- 2 ounces unsalted butter (4 tablespoons, half a stick)
- 1/2 cup light brown sugar
- 1/4 cup brandy
- big pinch salt
- 2 medium nectarines, sliced into eighths
- 2 large plums, sliced into eighths
The cake:
- 3/4 cup almond paste (6 3/4 ounces)
- 6 ounces unsalted butter, softened (1 1/2 sticks, 12 tablespoons)
- 3/4 cup sugar (preferably organic turbinado)
- 4 large eggs, at room temperature
- 1/2 cup + 1 tablespoon oat flour (2 1/2 ounces)
- 1/2 cup sticky rice flour (2 1/2 ounces)
- 3/4 teaspoon baking powder
- 1/4 teaspoon salt
Instructions
Get the party started:
- Position a rack in the center of the oven and preheat to 350ºButter a 9" round cake pan and set aside.
Make the topping:
- In a medium skillet over medium heat, melt the butter. Whisk in the brown sugar and salt, cook until bubbling, then slowly add the brandy (it will flame up if you add it too quickly). Cook, whisking, until the caramel is bubbling thickly, 2-3 minutes. Pour the hot caramel into the greased pan. When the caramel has cooled (it will still be fairly liquid), arrange the plum and nectarine wedges in concentric circles, nestling them close together. Set aside while you...
Make the cake batter:
- In the bowl of a stand mixer fitted with the paddle attachment, beat the almond paste and butter until combined, scraping down the bowl and beater as needed. Add the sugar, and beat on medium until light and fluffy, 3 minutes. Add the eggs one at a time, beating until combined after each addition.
- Sift the flours, baking powder and salt into a medium bowl, and add to the cake batter, beating until combined. (Since there is no gluten, you needn't worry about over-mixing the batter.) Scrape down the bowl and beater, give the batter a final fold with a spatula to make sure it is homogenous, then dollop the batter over the fruit and spread smooth.
Bake the cake:
- Bake until a tester inserted into just the cake comes out clean, about 1 hour. Immediately run a thin knife or small, off set spatula around the edge of the cake to loosen it. Place a large plate upside-down on top of the cake pan, put on your oven mitts, grasp both cake pan and plate firmly, and flip the whole thing over so that the cake is right-side-up. Remove the pan. Spackle any fruit or cake that got left behind back onto the cake. Let the cake cool for at least half an hour. Serve warm or at room temperature.
- The cake is best within the first 2 days of being baked.

I have a question. If I am trying to lower the overall sugar content--and by that I mean the additional sugar, not in the fruit itself--where would you start? It seems like the topping needs caramelized sugar, so maybe replace the sugar in the cake with unsweetened apple sauce or maybe use another sweetener like Grade B molasses?
Alanna says
Hi Mini,
Replacing sugar in cakes is particularly tricky as sugar adds moisture and tenderness as well as sweetness. You could certainly experiment with using applesauce; I'd be concerned that molasses' strong flavor might overpower the delicate almond and fruit flavors.
If you're cool with unrefined sugar, you could try either maple sugar, coconut sugar, date sugar, or unrefined cane sugar.
Another option would be to omit the topping altogether and bake the cake right-side-up, with the fruit on top. (You could decrease the sugar in the cake a bit and replace it with the brandy from the topping.)
Let us know what you end up trying! Happy baking. : )
Robyn Fuoco says
Mmmmm, thanks Alanna, this looks amazing! I love anything with almond paste. Must try this while stone fruits are still in season.
Alanna says
Yeah, do it!
rcakewalk says
Gorgeous, as always... and lucky you to have a techie friend to swap with. I need to find one of those! One of my favorite cakes this time of year is Dorie's dimply plum cake, which isn't upside down per se, but appears to be. I may make this for the weekend, to keep in my GF groove.
Alanna says
Yes, I'm totally lucky!
Your dimply plum cake looks fantastic - love the big chunks of plums, and it does look like an upside-down cake. Can't wait to give it a try!
Kelly Harms says
Just made this (for the second time) for my daughter's 23rd birthday. I used apples this time (with just a hint of cinnamon) -- It was wonderful with some sweetened whipped cream. Like a grown-up caramel apple!
Alanna says
Brilliant variation! Definitely have to try it. I bet pears would be good, too. Thank you so much for the inspiring comment!
Ksenia says
If one doesn't have any oat flour on hand, what can you substitute that with? I read online that you could substitute with white rice flour. Is this true?
Also what a beautiful post! Can't wait to try making this.
Alanna says
Hi Ksenia, You could definitely try white rice flour! The texture may change a bit, but I think it should work here. Otherwise any GF AP blend would probably do the trick since this particular cake is quite forgiving. LMK how it goes if you give it a try!
Margaret says
Hi Ksenia,
If you have gluten-free oats at home (the slow-cooking kind), you can always grind it in your food processor until it has the consistency of flour. If not, try quinoa flour or even amaranth. I've had lots of success using quinoa flour in cake recipes. The texture is very moist and there's no weird taste or grainy texture. I prefer it to using rice flour of any kind. Just as a side note, all rice flours are highly glycemic (they raise your blood sugar) which is why I prefer to use as many alternatives to that as possible. Good luck :-)
Jillian says
Can I substitute anything for the sticky rice flour? The grocery stores near me don't carry that kind of flour, nor the rice!
Alanna says
Hi Jillian, No worries – I think any GF all-purpose blend should work, especially Bob's Red Mill 1 to 1 which is based on sweet rice flour. This cake is quite forgiving. Please let me know if you give it a go!
Ashlyn says
Hi! I don’t happen to have any Brandy on hand. Anything I could substitute? Thanks!
Alanna says
Definitely! You could use another spirit such as whiskey, bourbon, or a dark or gold rum. Or you could use some black tea. Let me know if you try the recipe, it's one of my all-time favorites. :)
