  • Arrange plums in a circular pattern on top of the cake batter until the batter is covered completely.
  • For the streusel mix the sugar, cinnamon, soft butter and flour in a bowl. Mix until it starts clumping together. Take it out of the bowl and sprinkle it evenly over the plums.
  • Bake the cake for 50 to 55 minutes or until golden brown, and insert toothpick in center of cake to see if it comes out clean.
  • Let the cake cool down completely before slicing. Serve with whipping cream or a scoop of vanilla ice cream
