1. Preheat oven to 350°F (175°C). Grease a 9-inch springform pan with melted butter and line the bottom with parchment paper.
2. In a large bowl, whisk together the flour, 150g sugar, baking powder, salt, and cinnamon until no lumps remain.
3. Create a well in the center of the dry ingredients and add the Greek yogurt, vegetable oil, eggs, and vanilla extract.

5. Cut plums into uniform 1/4-inch rounds.
6. Pour the batter into the prepared pan and smooth the top. Press the plum slices gently into the batter in a concentric circle pattern.
7. Sprinkle the top of the plums with 1 tbsp of granulated sugar.
8. Bake for 45 minutes or until a toothpick inserted into the center comes out clean.
