Simple and delicious, even better for breakfast the next day! This cake is moist, chewy, not too sweet and perfect alongside a scoop of vanilla ice cream. The lemon zest perks it up to the point of perfection and the sugar and cinnamon sprinkled over the top adds just a touch of sweetness. - Kaitlyn —The Editors
Preheat the oven to 350 degrees. Lightly grease a baking pan (about 8 X 8 inches). Halve plums, remove pits and dice (keep skin on). In a separate bowl combine the flour, baking powder and salt.
In a stand mixer or by hand, cream the butter and 3/4 cup sugar. Add the eggs one at a time, beating well, then the vanilla and lemon zest. Stir in the diced plums and then the flour mixture until just combined.
Pour batter into baking pan. Bake in the centre of the oven 30-40 minutes until a skewer inserted into the middle comes out clean. Meanwhile combine the additional sugar and cinnamon.
Remove cake from oven, dust with the cinnamon sugar and allow to cool. Serve as is or with custard or butterscotch sauce!
