(Gluten-Free!) Rosemary Nectarine Upside-Down Cake

sliced (Gluten-Free!) Rosemary Nectarine Upside-Down Cake

As Paul F. Tompkins so astutely points out, there has been a debate raging in our society for many, many years: some people like pie more than cake, while other people like cake more than pie. I don’t hope to offer a solution to this age-old conflict of dessert interests, but I do have something that will bridge the gap (and it isn’t putting frosting on pie).

It is this cake. Yes, it is a cake, but due to a ton of gooey, baked fruit, it eats like a pie, especially when warm from the oven and dolloped with crème fraîche. It is a cake for pie-lovers.

The idea for this cake came by way of my friend Molly, who works for Happy Child, the CSA of renowned Frog Hollow Farm. Frog Hollow grows some of the most delicious, organic fruit in California, and their CSA boxes brim with seasonal goodness of the highest quality. When Molly showed up last week with a box piled high with red grapes, Emerald Beaut plums, August Fire nectarines and Cal Red peaches, I thought I might die of happiness (or at least sign up for their CSA).

Molly wanted to bake a vanilla-rosemary cake, and we decided to turn it into a peach upside-down cake, and to make the batter gluten-free. Neither of us is allergic to gluten, but we both try to reserve our wheat-eating for special occasions.

Molly looked at recipes for gluten-free yellow cakes and did complicated math to adapt the recipe to the flours we had, and the proportions of my go-to upside-down cake recipe, while I mixed up some rosemary peach cocktails to, uh, help us work. We settled on a combination of cornmeal and sweet rice, tapioca, oat, and millet flours and a touch of xanthan gum (for the cake, that is – not the cocktails).

We melted butter and brown sugar together in a skillet, then Molly layered nectarine slices in concentric circles. For our cake batter, we creamed together butter, sugar, rosemary, vanilla bean seeds and extract, then added a couple of eggs, a spot of crème fraîche, and the flour mixture. Since there’s never enough fruit in an upside-down cake for my liking, we folded some chopped nectarines into the batter as well.

The batter topped the fruit, and into the oven went our experimental creation.

The turned-out dessert looked beautiful, bronzed nectarines glistening atop a cake sticky with caramelized fruit juice and buttery brown sugar. When we each bit into a slice, I said, “Oh my god, it’s perfect!” while Molly said, “um – best cake ever!” I made a second one the very next day, just to double check the ingredients. Not because I needed to have an entire cake all to myself. Definitely not.

The gold standard for gluten-free goodies is that they have a texture that is as good as its wheaty equivalent. This cake goes above and beyond: its texture is more melt-in-your-mouth tender than any wheat-based cake I’ve ever had. It is what every cake wants to be. (Minus the frosting.)

You first taste the soft, caramelized fruit – a little sweet, a little tangy. Then you get the subtly savory hint of rosemary that makes its presence known, but doesn’t take over. Next, you taste the heavenly pillow of sweet and tender cake. Just when you think the show is over, you get a few crunchy nubs of cornmeal as a last-minute surprise.

This is one of those excellent transitional summer-to-fall desserts; bright with summer fruit, but gooey and comforting at the same time, with wintery notes from the rosemary.

I don’t like to use the “P” word, but I truly believe that this is the perfect cake…

(Gluten-Free!) Rosemary Nectarine Upside-Down Cake

Print Recipe  /  Pin Recipe
This is one of those excellent transitional summer-to-fall desserts; bright with summer fruit, but gooey and comforting at the same time, with wintery notes from the rosemary.
Prep: 30 minutes
Cook: 50 minutes
Total: 1 hour 20 minutes
Servings: 10 servings (makes one 10" round cake).


For the fruit topping:

  • 3 tablespoons unsalted butter (1 1/2 ounces)
  • 1/2 cup packed light brown sugar (3 ounces)
  • 1 1/2 pounds ripe but firm nectarines (about 3-4 large, or 6 medium)

For the cake:

  • 8 tablespoons unsalted butter, softened to room temperature (4 ounces/1 stick)
  • 1/2 cup granulated sugar (4 ounces)
  • seeds from 1 vanilla bean (bean split lengthwise, seeds scraped out, pod saved for another use)
  • 2 tablespoons finely chopped fresh rosemary
  • 1 teaspoon vanilla extract
  • 2 large eggs, at room temperature
  • 3/4 cup sweet white rice flour (4 ounces)
  • 1/4 cup millet flour (1 1/4 ounces)
  • 1/4 cup oat flour (1 ounce)
  • 1/4 cup stone-ground yellow cornmeal (1 1/4 ounces)
  • 2 tablespoons tapioca starch (1/4 ounce)
  • 1/2 teaspoon xanthan gum
  • 2 teaspoons baking powder
  • 1/4 teaspoon salt
  • 1/3 cup crème fraîche (or sour cream), plus extra for serving (2 1/2 ounces)
  • 1 cup chopped nectarines, from above


Make the topping:

  • Position a rack in the center of the oven and preheat to 350ºF.
  • Place the butter in a 10" oven-proof skillet with 2" high sides, and put it in the oven to melt the butter. Brush some of the butter up the sides of the pan. Sprinkle the brown sugar over the butter, and place in the oven until the brown sugar is moistened and bubbling, 5 minutes.
  • Halve and pit the nectarines, and slice them fairly thin, about 1/8" thick. Set aside the end pieces. Beginning with the largest pieces, place the nectarine slices over the brown sugar with the curved edge facing out, overlapping the fruit as you go. Continue to make circles with the nectarine slices until you've covered the pan. Chop the remaining slices and end pieces; you should have 1 cup. Set these aside to add to the batter.

Make the cake batter:

  • In the bowl of a stand mixer fitted with the paddle attachment, beat together the butter, sugar, vanilla seeds, and rosemary on medium speed until light and fluffy, 3 minutes, scraping down the sides of the bowl occasionally. Beat in the vanilla extract, then the eggs one at a time. (The mixture may look curdled; this is O.K.)
  • Meanwhile, sift together the flours, tapioca starch, xanthan gum, baking powder, and salt into a medium bowl.
  • With the mixer on low speed, stir in half of the flour mixture, beating until just combined. Beat in the crème fraîche until combined, then the remaining flour mixture. Scrape down the sides of the bowl, and give the batter a stir to make sure it is mixed thoroughly. Fold in the chopped nectarines by hand until just combined.
  • Dollop the batter over the nectarines in the pan, and spread it gently and evenly.
  • Bake the cake until a tester inserted in the center of the cake comes out completely clean, about 45 minutes. Let the cake cool for 5-10 minutes (but no more, or the caramel may harden, causing the fruit to stick to the pan. If this happens, put the cake back in the oven for 5 minutes to re-melt the caramel).
  • Invert a large plate or platter over the pan, grasp it tightly with two oven-mitted hands, and bravely flip the whole thing over. The cake should release easily from the pan.
  • Let the cake cool to warm, 20 minutes, then serve warm or at room temperature, dolloped with crème fraîche. The cake is at its most gooey and pie-like on the first day, but leftovers will keep at room temperature for an additional day, or in the fridge for a few. Re-warm before serving for best results.


I think this cake would be awesome made with ripe pears in place of nectarines; apricots, plums, or, of course peaches could all stand in for the nectarines, too.
If gluten isn't an issue, use 1 1/4 cups all-purpose flour in place of the rice, oat and millet flours and omit the tapioca starch and xanthan gum. If you or your guests are highly sensitive to gluten, be sure to seek out flours and other ingredients that are certified gluten-free. Also, be sure to use sweet rice flour here (such as Mochiko brand); this is made from sticky rice, and has a finer, stickier texture than regular white or brown rice flours.
You can make your own crème fraîche by stirring 1 tablespoon buttermilk into 1 cup heavy cream and letting it sit, covered, at room temperature for 24 hours. Stir it a few times as it sits, then cover and refrigerate. It should keep for at least 1 week.

  1. Beautiful cake! Very impressed. Just discovered your blog when I was looking for an apricot tart recipe. Love seeing all the wonderful photos and recipes. We're not gluten-free, but always looking for inspiration for dairy/egg/almond-free treats for my son.

  2. Hi Alana, This is just beautiful! I tend to prefer pies…but I think that both pie and cake lovers will be very pleased with this dessert. Thank you so much for sharing it!

  3. Alanna – So glad this recipe is finally up! Will definitely be making it next time I get my hands on some tasty nectarines. Looking forward to trying out more of your recipes in the future! – Chelsea (friend of Molly's that got to try one of the original cakes!)

    1. Thank you, Eva! That is high praise from a creator of stunning things yourself! :) There's something about this time of year that has me positively obsessed with rosemary. (Rosemary cocktail coming up next…)

  4. This is one of my favorite GF desserts ever. We made it multiple times with nectarines this summer, and I'm making a pear one right now. I regularly refer my friends to this recipe, and to your beautiful site. Thank you for all that you do!

    This recipe is extra delicious and less expensive with homemade creme fraiche. Mmm. You can also whip and lightly sweeten the creme fraiche to put on top, if desired. So much yummier than whipped cream. Love that light tang!

    1. Hi, Cordelia! Thank you for the sweet note, and for sending other GF bakers this way! I'm so glad to hear that you like the cake – it's one of my favorite ever recipes, too. I'm a huge creme fraiche fan, too…mmm… :)

  5. That looks so DARN amazing and delicious!!!! Now, do you have something very similar to this beauty that you'd recommend in your vegan section? I was looking at the ingredients for this and going to try to veganize it, but what could I use instead of creme fraiche? Any ideas? I MUST have this! lol

    1. Hi, Patricia! You know what I bet would work? The cream that settles on the top of a can of coconut cream. That's probably the closest thing to crème fraîche. Alternately, some type of vegan yogurt. Maybe Earth Balance buttery spread for the butter, and flax eggs for the eggs? Promise me you'll come back and let me know how it comes out.

    2. Excellent idea with the coconut cream! Will definitely try it – excited :) This week is a little crazy for me, but I plan on making this next week if nectarines are ripe. I'll for sure let you know results! Thanks so much for responding and offering suggestions!! ;)

  6. Wow…came across this and your absolutely enticing description lured me in! I made this tonight, followed your instructions exactly, and it turned out… Perfect! What a lovely cake! Thank you for an awesome gf recipe! No one at the dinner party guessed it was gluten-free!

  7. I absolutely adore your site and recipes – everything is an absolute hit with family and friends and I get a lot of, “I would have never known this was gluten free,” which is saying something for a family of amateur but exacting bakers.

    Anyway, besides the gushing, I’m excited to try this, but am currently on a small island with limited grocery options. Do you think greek yogurt would work as a creme fraiche sub?

    1. Your note completely made my day – thanks for the sweet words! I think greek yogurt would probably work, though sour cream would also be an easy peasy substitute with a more similar fat content. :) Please let me know how you like it!

  8. I made this just for fun this week and the flavor combination is AMAZING! My co-workers loved it, my boyfriend loved, I loved it– everyone loved it! Thanks for making recipes that show people gluten free baking doesn’y have to be dull, bland and dry.
