How to Make Mama's Rhubarb Crunch

  1. Preheat oven to 375°F (190°C).
  2. In a medium bowl, combine 4 cups chopped rhubarb, 1 cup granulated sugar, and 2 tablespoons cornstarch. Gently toss to coat.
  3. Pour the rhubarb mixture into a greased 9x9 inch baking dish.
  4. In a separate bowl, combine 1 cup rolled oats, ½ cup all-purpose flour, ½ cup packed light brown sugar, ½ cup (1 stick) unsalted butter, cut into small pieces, and ½ teaspoon ground cinnamon.
  5. Use your fingers or a pastry blender to cut the butter into the dry ingredients until the mixture resembles coarse crumbs.
  6. Evenly sprinkle the crumble topping over the rhubarb filling.
  7. Bake for 40-60 minutes, or until the topping is golden brown and the rhubarb is bubbly. If using frozen rhubarb, bake for the full 60 minutes.
  8. Let cool slightly before serving warm. Enjoy with a scoop of vanilla ice cream!
