  • 1 cup granulated sugar
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon ground ginger
  • 2 tablespoons cornstarch
  • 2 teaspoons warm water

Crust

  • 1 box white cake mix

  • 1 egg

Cobbler Topping

  • 1 cup crust mix without the egg
  • 1/2 cup rolled oats
  • 1/4 cup light brown sugar
  • 2 tablespoons melted butter

Instructions
 

Making the Plum Filling

  • Make the filling by cooking the chopped and seeded plums in a heavy bottomed saucepan with 1 cup sugar, 1 teaspoon ground ginger, and 1 tablespoon lemon juice.
  • Stir fruit until the sugar is dissolved and then let simmer on low heat for about 10 minutes stirring and mashing the fruit occasionally.
  • Mix 2 teaspoons of warm water with 2 tablespoons of cornstarch and add it to the plum mixture.
  • Continue simmering and stirring occasionally for 10 more minutes until the fruit thickens and starts to look like jam.
  • Remove the pan from the heat and let cool.

Making the Crust

  • In a large bowl combine the cake mix with 1 cup of rolled oats and 1/2 cup melted butter. Stir until combined.
  • Reserve 1 cup of this mixture for the crumble topping.
  • Next, add one egg to the cake mix and mix until it is well combined.
  • Place drops of the mixture evenly into a sprayed 9 x 13 baking pan.
  • Use the backs of your fingers to press the crust evenly on the entire bottom of the pan.
  • Spoon the cooled plum filling over the crust.
  • In another bowl mix together the reserved 1 cup of the crust mix with 1/4 cup of brown sugar, 1/2 cup of rolled oats, and 2 tablespoons of melted butter.
  • Sprinkle the topping in an even layer over the plum filling.
  • Bake in a 350 degree oven for 25 minutes.
  • Remove from the oven and allow the baking pan to cool for 15 minutes or more before cutting into 20 even bars.
  • Place the bars on a cooling rack to continue to cool and set.

Notes

If you're not a ginger fan, you could substitute ground cinnamon for the ginger or leave it out completely.
After the plum cobbler bars have thoroughly cooled store them in an airtight container with pieces of wax or parchment paper between layers for a day or two. Afterward, place them in the refrigerator to maintain freshness.
You can also freeze them in plastic freezer bags for a couple of months.
