Step by step

Method

4 steps

1. 1

   In a large bowl, beat butter and 1 cup (200 grams) of the sugar together with an electric mixer until fluffy and lighter in color. Add the eggs, one at a time and scraping down the bowl. Sift flour, baking powder, and salt over batter and mix it until just combined.

2. 2

   Spoon batter into prepared cake pan and smooth the top. Arrange the plum tightly in the pan, skin side up, all over the batter, covering it. Sprinkle the top with lemon juice, then cinnamon, then remaining sugar.

3. 3

   Bake until cake is golden and a toothpick inserted into a center part of the cake comes out free of batter (but of course not plum juice), about 45 to 50 minutes. Cool on rack.

4. 4

   Once cool, if you can stand it, and I highly recommend trying, leave it at room temperature overnight as this cake is even better on the second day, when those plum juices further release into the cake around it, becoming not just “cake with plum,” but cakeplumughyum (official terminology, there). If planning more than 2 to 3 days out, I’ll store the cake in the fridge for longevity.
