This moist cake—scented with orange zest and crowned with ruby pink, tart rhubarb—is a keeper. It has plenty of appeal and it earns it! You can whip it up at the drop of a hat in the food processor. Very little washing-up is required, and I always vote for that.

How To Buy and Store Rhubarb

Rhubarb is in season primarily from April to June in the U.S., but you can sometimes find it a little earlier or later than that. Look for stalks that are less than two inches in diameter and that are blemish-free and firm. You don’t have to peel them. Their color can range from green to pink to deep red.

If the stalks have leaves, they should look fresh, not wilted. The leaves of rhubarb are poisonous, so be sure to remove and discard them. Store the stalks, unwashed, in a plastic bag in the refrigerator for up to one week.

How To Freeze Rhubarb

If you have a good haul of rhubarb, you can cut the raw stalks into pieces, spread them on a parchment-lined baking sheet to freeze, and pop them into freezer bags once they are frozen. They should keep for up to 12 months.

Grinding Your Own Almonds Vs. Almond Flour

Personally, I prefer the flavor of toasted almonds and the slightly coarser texture that comes from grinding the nuts in the food processor to make my own almond flour. But if you don’t have the time or the inclination to make your own, you can substitute store-bought almond flour in this recipe.

Can I Use a Cake Pan If I Don’t Have a Skillet?

You can use a 9- or 10-inch round cake pan that is at least two inches deep for this cake. I suggest buttering the pan and then lining the bottom with a round of parchment paper to fit. Check the cake for doneness after about 40 minutes, since baking time can vary according to the pan you use.

How To Store and Freeze This Cake

The cake is best eaten on the day it is made, but having said that, it keeps well for two to three days, covered tightly with foil stored at room temperature. To freeze the cake for up to three months, wrap it in plastic wrap then aluminum foil.

Prep Time 15 mins
Cook Time 50 mins
Total Time 65 mins
Servings 8 servings


  • Butter (for the skillet)

  • 2/3 cup whole almonds with skins or 3/4 cup almond flour

  • 3/4 cup granulated sugar, divided

  • Zest of 1 medium orange

  • 1 cup all-purpose flour

  • 1 1/4 teaspoons baking powder

  • 1/8 teaspoon kosher salt

  • 1/2 cup (1 stick) room temperature unsalted butter, cut into slices

  • 3 large eggs

  • 1 teaspoon vanilla extract

  • 2 to 3 stalks rhubarb (8 ounces), leaves removed, cut into 1-inch slices (about 2 cups)

  • Powdered sugar (for sprinkling)

Special Equipment

  • Food processor


  1. Preheat the oven and prep the skillet:

    Preheat the oven to 350°F. Generously butter a 10-inch ovenproof skillet with a heatproof handle.

  2. Toast the almonds:

    Spread the almonds on a baking sheet and bake for 8 to 10 minutes, or until they smell toasty. Cool briefly.

  3. Grind the almonds:

    In a food processor, add the almonds, 1/4 cup of granulated sugar, and orange zest. Process until the mixture looks like coarse sand. Transfer the mixture to a bowl. Remove 1/4 cup of the almond-sugar mixture for the topping and set aside.

  4. Combine the almonds and flour:

    Add the flour, baking powder, and salt to the almond-sugar mixture in the bowl. Whisk to combine.

  5. Make the batter:

    In the food processor, process the butter and the remaining 1/2 cup granulated sugar for 1 minute, or until light and fluffy. One at a time, add the eggs, processing for about 30 seconds after each addition and scraping down the sides of the food processor with a spatula. Add the vanilla and pulse to mix it.

    Add the flour mixture to the food processor and briefly pulse the machine 4 to 5 times, just until the batter is smooth. It will be thick.

  6. Transfer to the skillet and top:

    Scrape the batter into the skillet, spreading it evenly in the pan with the back of a spoon or small spatula.

    Sprinkle about half of the reserved almond-sugar mixture over the batter in the pan. Distribute the rhubarb over the top of the batter. Sprinkle with the remaining almond-sugar mixture.
