Ingredients

Crust & Topping

  • 2 1/4 cups all-purpose flour

  • 1 cup rolled oats

  • 1/2 cup brown sugar

  • 1/2 cup cane sugar

  • 1 1/2 teaspoons baking powder

  • 1/2 teaspoon salt

  • 14 tablespoons butter, melted

Filling (Choose One)

 
  • Jam of choice
    or

  • 2 cups fruit

  • 1/3 cup brown sugar

  • 3 tablespoons flour

  • Pinch of salt

  • Splash of vanilla

Instructions

  1. Preheat the oven to 375°F. Line or grease a baking dish and set aside.

  2. In a large bowl, combine the flour, oats, brown sugar, cane sugar, baking powder, and salt. Pour in the melted butter and stir until the mixture is evenly combined and crumbly.

  3. Press about two-thirds of the mixture firmly into the bottom of the prepared pan.

  4. If using jam, spread it evenly over the base. If using fruit, mix the fruit with brown sugar, flour, salt, and vanilla, then spread evenly over the crust.

  5. Sprinkle the remaining crumb mixture evenly over the filling.

  6. Bake for about 50 minutes, until the top is lightly golden and the filling is set.

  7. Allow the bars to cool completely before cutting. This helps them hold together and slice cleanly.
