How to Make Plum Upside Down Cake

1. Preheat the Oven: Begin by preheating your oven to 160 °C (fan-forced). While the oven is warming, line the base and sides of a 23cm cake tin with baking paper to prevent sticking.

2. Prepare the Sugar Mixture: In a small bowl, combine caster sugar and ground cardamom. Sprinkle this fragrant mixture evenly across the bottom of the prepared tin, forming the sweet base for the plums.

3. Arrange the Plums: Take your firm, ripe plums and slice them in half. Arrange the plum halves, cut side down, in a stunning circular pattern to cover the sugar mixture completely.

4. Cream the Butter and Sugar: In a large mixing bowl, beat together the softened butter and caster sugar until the mixture is pale and creamy. Add each room-temperature egg one at a time, ensuring they re well incorporated.

5. Mix in Flavorings and Dry Ingredients: Stir in the orange zest and vanilla bean paste, then gently fold in almond meal, polenta, and baking powder until just combined. Avoid over-mixing to keep the cake fluffy.

6. Add the Batter: Spoon the luscious batter over the beautifully arranged plums in the tin. Smooth the top with a spatula for an even bake.

7. Bake the Cake: Place the cake in the preheated oven and bake for about 1 hour, or until a skewer inserted into the center comes out clean. The cake should be lightly golden on top.

8. Prepare the Mascarpone Topping: In a separate bowl, mix mascarpone cheese with the remaining orange zest, juice, and icing sugar until the mixture is smooth and creamy. This will be a heavenly topping for the cake!

9. Invert the Cake: Once baked, allow the cake to cool slightly before gently inverting it onto a serving plate, ensuring the plum side is facing up. Serve it warm or cooled with your mascarpone topping.

Optional: Garnish with a sprinkle of extra orange zest for added brightness.
