Sour Plus Brown Butter Upside Down Cake // A Cozy Kitchen

You guys, I usually hate summer. Hate. Sitting by the fire, wearing scarves and loving autumn leaves is more my thing. This blog is called a cozy kitchen, after all. There’s not a lot of coziness going on in the summer time, unless you include turning the AC on blast–which I don’t have, unfortunately–to 50 degrees and piling on the blankets. I dream of this.

But this year I’m not minding summer. Maybe it’s the bbqs with friends or the summer dresses from Target that I’m loving or the summer fruit. I feel like all that stuff combined has made sweating a-ok. (Kinda.) These sour plums were a gift from my dude. He doesn’t give me jewelry; he gives me fun produce. I don’t mind one bit.

These sour plums are tart. Phew. So good and tart.

Big gigantic note: these are not to be confused with sour green plums. The sour plums used in this cake are a lot less tart than sour green plums. Sour green plums will make your face contort in unattractive ways. I’ve had a few in my day and man, they’re so tart they’re borderline unenjoyable. These sour plums are almost the same color as regular ol’ plums and about half the size.

Bonus: this recipe will totally work with regular ol’ plums, too. I’d just recommend going with very firm plums. This way they’ll keep their shape in the oven through the baking process.

My favorite part about this whole dang cake is how the sweet, nutty brown butter coats the plums. It’s a dreamy cake that’s even better served with a big dollop of whipped cream or ice cream.

Ok…I’m going to talk about something boring right now! Are you ready?! As many of you know, Google Reader shut its doors today. This is so very sad, especially since so many of you read this blog via Google Reader.

I ended up transferring my Google Reader to Feedily. I think the layout is absolutely beautiful. I recommend it.

Prep Time: 15 minutes
Cook Time: 7 hours 30 minutes
Total Time: 1 hour 5 minutes
Serving Size: 1 twelve-inch cake

Ingredients

Cake:

  • 2 cups all-purpose flour
  • 1 3/4 teaspoon baking powder
  • 1/2 teaspoon ground cinnamon
  • 1/8 teaspoon freshly grated nutmeg
  • 1/2 teaspoon fine-grain sea salt
  • 4 ounces 1 stick unsalted butter, room temperature
  • 1/2 white granulated sugar
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
  • 3/4 cups whole milk

Sour Plum Topping:

  • 5 tablespoons unsalted butter
  • 1/2 cup dark brown sugar
  • 1/4 teaspoon fine-grain sea salt
  • 1/4 teaspoon ground cardamom
  • 1/8 teaspoon freshly grated nutmeg
  • 2 pounds sour plums, about 10 plums, halved and pitted

Directions

  • Preheat the oven to 350 degrees F.
  • In a small to medium bowl, mix together the flour, baking powder, cinnamon, nutmeg and salt. Next, in a medium bowl, cream together the butter and sugar until light and fluffy. Add the eggs and vanilla; and then mix until the mixture is smooth.
  • To the butter and sugar mixture, mix in half of the flour mixture and the milk. Then, mix in the remaining flour mixture, being sure not to over mix.
  • In a 12-inch cast iron skillet (*see note below about alternative vessels), melt the butter over medium heat. Cook the butter for 2-3 minutes, until it begins to turn a light brown color. Using a spatula, coat the sides of the cast iron skillet with the butter--this will ensure the cake won't stick. Mix in the brown sugar, salt, cardamom, and nutmeg until the sugar begins to bubble, about 1 minute. Turn off the heat and let stand for a few minutes to cool slightly. Next, arrange the plums to your liking. Just be sure to put as many as you can fit, and pack them tight--the plums shrink as they bake.
  • Pour the batter over the plums, and spread the batter gently so it’s nice and even. Transfer the cast iron skillet to the oven and bake for 35-45 minutes or until a skewer comes out clean.
  • Remove the cake from the oven and allow to cool for 5-10 minutes. To invert the cake, run a butter knife alongside the outside of the cake and place a (large enough) plate on top of the cast iron skillet and turn both of them over; lift up the cast iron skillet and voila! Your cake!

I like to serve this cake slightly warm with a dollop of whipped cream, but ice cream is a good move too.

    Notes

    If you don’t have a 12-inch cast iron, you can surely use a 10-inch cast iron skillet or a 10-inch cake pan. If you use a 10-inch cast iron skillet you may have a bit of batter leftover and the cake part will be thicker. No biggie! If you use a 10-inch cake pan, you’ll need to do step #4 in a skillet and then pour the caramel mixture into the cake pan.

    For some reason the cook time shows 7 hours 30 minutes?

    The cake is simple but tasty, and the cast iron gives the edges a nice crust. The plums, which I can find bitter in their fresh form, mellow out as they bake to become lightly sweet and tart, even the peel. A dollop of whipped cream makes a slice even better.

    In your recipe you say 1/2 white granulated sugar. Is that 1/2 CUP?

    I’m with you. It is 118 degrees here in Scottsdale, AZ and I have zero tolerance for it. This recipe screams summer and gives me the perfect excuse to stay indoors and bake. Afterall, my oven is cooler than outside!

    Like how fluffy the cake is. And with the plums on top. So gorgeous. We don’t get spur plums here much. I can replace this with any soft fruit, right?

      I bet it’d work great with sliced peaches too! I’d just go with firmer ones.

        Wow… you reply really quickly! I’ll try it out soon! My parents would love this 🙂 Pinning for later.
