Rhubarb Upside-Down Cake
I was a bit intimidated by this rhubarb upside-down cake recipe because, well, it’s a cake recipe! Our collection of cake recipes is continuing to grow here on Platter Talk. Still, every time that I put a cake together, I have the same cluster of fears.
What if it’s too dry? What if it’s soggy? What if it falls in the center? What if I completely screw it up? As I have discovered over the years, my fear of baking cakes is silly. If you think you can’t make this cake, the same is probably true for you!
Celebrate Spring with Rhubarb Cake!
Rhubarb only comes around for a brief time here in Wisconsin. Since I hardly ever get to cook with it, I was especially anxious about this recipe. After I had one bite, it was clear that all that anxiety was one of the biggest wastes of my energy. Ever.
This rhubarb upside-down cake recipe uses about 4 cups, or about a pound and a half of sliced rhubarb. To be safe, I decided to use my trusty kitchen scale.
There are a thousand and one ways to measure ingredients. But using a kitchen scale is the only one way to measure ingredients with accuracy and precision. A cup of flour to you may be a different cup of flour to your neighbor, depending on what you use to measure it with!
Certain flavors and ingredients pair well together.
- Peas and carrots (think Forest Gump)
- Apples and cinnamon
- Chocolate and blueberries
- Cilantro and avocado
- As I found out, we can add one more match that is made in culinary heaven to this list: Rhubarb and Lemon.
This rhubarb dessert has all the usual cake ingredients, like flour, butter, and eggs. But there is one more ingredient that makes this cake recipe special: Sour cream
Not a lot, just a third of a cup but enough to give the cake an understated creamy texture. It’s pure heaven on a plate.
The batter may curdle at first, after the lemon juice and sour cream mix together. Although this may look weird, it’s completely O.K. After you mix the rest of the batter ingredients for a few minutes, you have a silky smooth creamy cake batter.
You’re going to make a brown sugar and butter base for this cake. Then, you will evenly distribute that base into a buttered spring-form pan. Be sure to line the pan with parchment paper to keep the cake from sticking.
Add the chunks of rhubarb along with their juices over the base. Then, pour the batter over the top of the rhubarb base. Finally, you will bake this at 325° for about an hour and 15 minutes. Use the toothpick test to tell when the cake is ready to come out of the oven.
It takes about 75 minutes to bake this beautiful rhubarb dessert and take my word for it that it is worth the wait!
I was hoping this rhubarb upside-down cake recipe would turn out well but had no idea just how great it would taste. I was blown away by its beauty and its deliciousness!

Rhubarb Upside-Down Cake Recipe
- 1.25 cups unsalted butter 2 and a half sticks and a little more to greast the pan
- 4 cups rhubarb about 1.5 lbs, rinsed and sliced into quarter to half-inch cubes
- 1 tbsp corn starch
- 1.5 cups granulated sugar
- 1/2 cup brown sugar
- 2 cups cake flour
- 1.5 tsp baking powder
- 1/2 tsp salt
- 1 lemon juiced and grated zest
- 1.5 tsp vanilla extract
- 4 eggs large
- 1/3 cup sour cream
- Preheat oven to 325°F. Line the bottom of a 9 inch spring-form pan with parchment paper and then grease the sides of the pan and the parchment paper with butter. Next, wrap two layers of aluminum foil around the base of the pan. Place the spring-form pan on a rimmed baking sheet.
- Using medium size mixing bowl, combined rhubarb and 1/2 cup sugar and stir well. Sprinkle cornstarch into mixture, while stirring gently until thoroughly combined.
- Place 1/2 stick of butter into a small sauce pan over medium-low heat and slowly melt it. Add the brown sugar, whisk until smooth, about 2 minutes. Next, combine combine cake flour, baking powder, and salt in a small mixing bowl. Gently stir together until well combined.
- Using the paddle attachment of a stand mixer, whip the 2 remaining sticks ( one cup) of butter for about two minutes. Lower the mixer speed to low and add remaining 1 cup of sugar. Turn mixer off and use your fingers to blend in the lemon zest until completely mixed in and the mixture is uniform in color. Next, add the vanilla and cream this mixture together in the sand mixer, for about four minutes. Reduce speed to low and add the eggs, one at a time. Use a rubber spatula to scrape sides and bottom of bowl after the addition of each egg. Add the sour cream and 1 tablespoon of the lemon juice. It's normal for the mixture to curdle at this point. With the mixer speed on low, add the flour mixture a little at a time and scrape the sides and bottom of the bowl as you add the dry mixture.
- Use a tablespoon or rubber spatula and pour the brown sugar and butter mixture into the prepared spring-form pan. It may be necessary to gently reheat the mixture prior to doing this. Next, spoon the rhubarb pieces and their juices onto the brown sugar and butter base. Finally, spoon the cake patter over the rhubarb, making sure to evenly distribute the batter and smooth it out with the back of a spoon or a rubber spatula.
- Bake for 70-75 minutes or until firm and a tooth pick comes out clean after being inserted in cake's center. Cool on a wire wrack for 15 minutes and then use a paring knife to loosen the edges of the cake from the sides of the pan. Place a serving platter on top of the spring-form pan and invert while the cake is still warm. Waiting too long to release the cake from the pan may cause it to stick to the sides of the pan.
- Use cake flour if possible for making this rhubarb cake. It will give you a lighter crumb and taste. If you don't have cake flour, all-purpose flour will work as well.
