Blueberry Oatmeal Crumble Bars


For the crust/crumble mixture

  • 1 cup plus 1 tablespoon whole wheat pastry flour (not regular whole wheat, this is a finer ground variety..can also sub all purpose)
  • 3/4 cup oats
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon cinnamon
  • 1/2 teaspoon salt
  • 1 large egg
  • 1/3 cup brown sugar, loosely packed
  • 2 teaspoons vanilla extract
  • 1/2 cup coconut oil, melted and cooled

For the berries

  • 2 1/2 cups berries (I used a mixture of blueberries, raspberries, and blackberries)
  • 1 tablespoon cornstarch
  • 1 tablespoon freshly squeezed lemon juice (from about 1 lemon)
  • 2 tablespoons pure maple syrup


  1. Preheat oven to 350℉. Spray a 8×8 glass baking dish with nonstick spray. Set aside.

  2. In a medium bowl, combine the flour, oats, baking powder, cinnamon and salt. Whisk to combine.

  3. In a separate bowl, whisk together the egg, brown sugar, vanilla, and coconut oil until smooth. Add the dry ingredients to the wet, and stir until mixture turns into a dough. Press ⅔ of the mixture into the bottom of the pan to form the crust. Set aside.

  4. In a medium bowl, combine the berries, cornstarch, lemon juice, and maple syrup. Gently stir until mixture is completely combined. Pour berries and their juices over the crust. Smooth out with a spoon or spatula so they’re evenly distributed.

  5. Top with remaining crust/crumble mixture, crumbling it evenly over the berries.

  6. Bake for 25-50 minutes or until crust is golden on the edges. Let cool completely before cutting! Unless you want to serve them warm with vanilla ice cream of course!
