How to Make Rhubarb Oatmeal Bars

  1. Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  2. In a medium saucepan, combine 4 cups chopped rhubarb, 1/2 cup water, and 1/2 cup orange juice (or pineapple juice). Bring to a simmer over medium heat and cook until rhubarb is tender, about 8-10 minutes. Set aside to cool slightly.
  3. In a large bowl, cream together 1 cup (2 sticks) unsalted butter and 1 1/2 cups granulated sugar until light and fluffy.
  4. Beat in 2 large eggs one at a time, then stir in 1 teaspoon vanilla extract.
  5. In a separate bowl, whisk together 2 1/2 cups all-purpose flour, 1 teaspoon baking soda, 1/2 teaspoon salt, and 1 teaspoon ground cinnamon.
  6. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  7. Stir in 3 cups rolled oats.
  8. Fold in the cooled rhubarb mixture.
  9. Pour the batter into the prepared baking pan and spread evenly.
  10. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  11. Let cool completely in the pan before cutting into bars.
