Instructions
Preheat oven to 350 F (180 C). Prepare 9 inch cake pan, either greasing it or spraying with baking spray and adding a parchment round at the bottom if needed. Alternatively, you can use a springform pan and prepare the same way.
Combine the flour, baking powder and salt in a small bowl with a whisk. Set aside.
Next, cream the butter and 1/2 cup granulated sugar (if you like a sweeter cake, you can increase the sugar to 2/3 cup) with an electric mixer until light and fluffy. Add eggs, one at a time and mix until combined. Add vanilla and almond extract ( if using) and mix until combined. Add flour mixture gradually on low speed JUST until combined.
Spread batter into prepared 9 inch non-stick cake pan. Slice the plums and arrange them in concentric, alternating circles until the top is filled. You may not need all of the plum slices.) Combine Demerara (or granulated) sugar and nutmeg in a small bowl and then sprinkle evenly on top of the cake. Bake at 350 F (180 C) for 40-45 minutes or until lightly browned and toothpick inserted into the cake comes out with no crumbs attached.
Cool in the pan for 10 minutes, and then invert onto a plate and continue to cool. Serve warm with ice cream or whipped cream. If you prepare the cake ahead, you can rewarm individual slices in the microwave for serving.
