Lightly coat a 13″”x9″” pan with cooking spray. Heat oven to 350 degrees. In large bowl, combine flour, baking powder, salt and 3/4 cup sugar. Add 1/2 cup softened butter, milk and eggs. Beat at medium speed 4 minutes.
Pour batter into prepared pan. Place plums on top, cut side up, pushing down slightly into batter.
Cut remaining 1/4 cup sugar and cloves into 3 tablespoons cold butter and sprinkle over plums. Bake about 40 minutes or until a toothpick tests clean.
Let the cake cool in the pan so the plum juices will be reabsorbed to create a moist cake. Sprinkle with confectioners’ sugar, if desired, and cut into 12 squares.
