Preparation Steps

• Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.
• In a bowl, whisk together flour, baking powder, baking soda, and cinnamon.
• In a larger bowl, beat the softened butter and sugar until light and fluffy.
• Add the eggs one at a time, beating well after each addition, then mix in the vanilla extract.
• Gradually add the dry ingredients to the wet mixture, alternating with milk, until well combined.
• Pour the batter into the prepared pan and arrange sliced plums on top.
• Bake for 40 minutes or until a toothpick inserted into the center comes out clean.
• Let the cake cool for 10 minutes before removing from the pan. Serve warm or at room temperature.
