plum upside-down cake

Posted by on July 5, 2010 in cook | 4 comments

I made up a cake recipe. Well, I started with a recipe and tweaked it so that it now bears little resemblance to the original. I have a fruit dessert thing going on this summer, I think I'm on dessert four for four consecutive weekends. 

This week at the grocery store the plums looked especially nice. I love upside-down cakes. You don't have to frost them, and I love the caramel-ly, fruity goodness on top. I had some almond meal that needed using, and I figured that this is the kind of cake that could benefit from the dense, moist texture. I made two cakes, one for Independence Day and the second for a potluck at work. The first one (above) I made in a springform pan, which resulted in a big, sticky mess on the bottom of my oven despite the fact that I wrapped foil around the bottom and outside. Oops. The second time I made it in my cast iron skillet, and it was a tight fit, there was still a little bit of overflow. Luckily, I put a big roasting pan underneath to catch any drips. 

Plum Upside-down Cake

12 T. Butter (a stick and a half)

1 c. packed brown sugar

5 plums, cut in half, pit removed, and each half cut into wedges

1/2 c. all purpose flour

1/2 c. white whole wheat flour

1/2 c. almond flour

2 t. baking soda

1/2 t. cinnamon

1/4 t. salt

1 c. sugar

2 large eggs

1/2 t. vanilla extract

1/2 c. cream

Preheat the oven to 350 degrees. Melt 6 tablespoons of butter in a 9" cast iron skillet. Add the brown sugar, and stir until sugar is melted and syrupy. Arrange the plum wedges in concentric circles in the bottom of the pan (or transfer the butter/sugar mixture to a 9" cake pan). Set aside. 

In a large mixing bowl, beat the remaining 6 tablespoon butter with the sugar, until fluffy. Add the eggs and vanilla, and beat until smooth and fluffy. In a smaller bowl, combine the flours, baking soda, cinnamon and salt. Whisk to combine. 

Add the dry ingredients to the butter/sugar/egg mixture, alternating with the cream. Stir just to combine after each addition. Spread batter over plums, and bake for 50 minutes, or until a knife inserted into the center comes out clean. 

Cool in the pan on a rack for 15 minutes or so, then place an inverted plate on top and quickly flip it over. It should come out nice and cleanly. It's good slightly warm or at room temperature. Top with dollop of whipped cream, if you like, although we had it plain, and it was delicious!

Let me know if you try it, and what you think!
