Plum Crumble Bars

Ingredients

  • 2 cups all-purpose flour
  • 1 1/2 cups old-fashioned rolled oats
  • 1/2 cup granulated sugar
  • 1/2 cup firmly packed light brown sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 3/4 cup (1 1/2 sticks) unsalted butter, cold and cut into 1/2-inch cubes
  • 3 medium plums, pitted and sliced thinly

Directions

Preheat oven to 350°F.

Combine flour, oats, sugar, brown sugar, vanilla, cinnamon, baking powder and salt in large bowl. Add butter and mix with pastry blender, fork or your fingers until combined. The mixture will be crumbly, but should hold together when pinched.

Set aside 1 cup of crust mixture.

Transfer remaining crust mixture to 9x13-inch baking pan. Press firmly and evenly into the bottom of the pan.

Bake crust for 10 minutes. Remove from oven.

Layer plums over partially baked crust, overlapping each slice a bit. Sprinkle remaining crust mixture over plums.

Bake 35 to 40 minutes, or until crust is golden brown. Cool completely before cutting into bars.

    Just 3 plums for a 9×13 that does not sound like much, maybe your plums are a LOT bigger than what I buy.

      That is possible. We recommend that you purchase the amount of plums you think will take to make a thin layer in a 9×13 pan.

      You can use as many plums as you’d like to layer in these bars! The more the merrier. Enjoy!
