  • 2 cups fresh rhubarb cut into ¼ inch pieces
  • 2 cups fresh strawberries cut into ¼ inch pieces
  • 1 tbsp lemon juice
  • 2 tbsp orange zest zest from 1 whole orange
  • ½ cup sugar
  • 2 tbsp chia seeds
  • 2 cups whole wheat flour I use white whole wheat
  • 1 cup uncooked quick oats
  • 1 cup oat bran
  • 1 cup brown sugar firmly packed
  • 1 cup butter softened
  • ½ teaspoon baking soda
  • ¼ teaspoon salt


  • Preheat oven to 350 degrees F.
  • Combine rhubarb, strawberries, lemon juice, and orange zest into a medium saucepan.
  • Cook fruit over medium heat, stirring occasionally until fruit is tender (about 10 minutes).
  • Stir sugar and chia seeds into fruit mixture.
  • Continue to cook fruit, stirring frequently for 1-3 minutes until mixture boils.
  • Continue to boil fruit for 1-2 minutes or until the mixture thickens.
  • Remove fruit from heat and set aside.
  • In a large bowl combine flour, oats, oat bran, brown sugar, butter, baking soda, and salt,
  • Beat crust mixture on low speed until the mixture crumbles.
  • Grease a 13x9 inch baking pan with butter.
  • Press crust mixture into the bottom of the baking pan reserving 2 cups for the topping.
  • Pour fruit mixture over crust carefully spreading fruit close to the edges.
  • Top with reserved crumble mixture.
  • Bake for 30 minutes or until browned.
  • Cool completely.

  • To lower the sugar content you can use a sugar substitute like Stevia or Swerve in place of the sugar and brown sugar if you wish.
  • Refrigerate before cutting. Getting the bars cold helps keep them together.
