For easy removal of the cake, place parchment paper on the bottom and 2 sides of the pan. Gently grease the other two sides and then set aside. Cut each plums into 8-10 small pieces each.
6-7 fresh plums
In a medium sized bowl, sift together flour, cocoa, baking powder, and salt. Stir to combine and set aside.
2 cups all-purpose flour, 1/4 cup cocoa powder, 2 tsp baking powder, 1/2 tsp salt
In a large bowl, add softened butter, vanilla, eggs, and white sugar. Beat on medium speed for 2-3 minutes until it’s light and there are no sugar granules when you feel it between your fingers. Make sure to scrap the sides of the bowl.
3/4 cups unsalted butter, 1/2 cup white sugar, 2 eggs, 1 tbsp vanilla
Mix in the dry ingredients and using a spatula, gently fold until a batter forms. Do NOT overmix! The batter will be thick.
Add the batter into the prepared pan and spread evenly in the pan. I recommend using your fingers for this as it's a thick batter.
Place the plums skin down on the cake. It's important they are skin down or else to much moisture will come out of them while they bake. See photos for reference.

Bake the cake for 35-45 minutes. It took me 42 minutes exactly. Allow the cake to cool. Then, melt chocolate and drizzle on the cake. Allow to set, slice, and enjoy!

This cake is best enjoyed the day of or next day (keep it in an airtight container on your counter).
