Ingredients

Scale
  • 4 cups rhubarb, chopped into 1/2-inch pieces (about 450 grams or 1 pound)
  • 3/4 cup granulated sugar (150 grams)
  • 2 tablespoons all-purpose flour (16 grams)
  • 1 teaspoon ground cinnamon (optional)
  • 1 teaspoon vanilla extract
  • 1 cup rolled oats (90 grams)
  • 3/4 cup all-purpose flour (90 grams)
  • 1/2 cup light brown sugar, packed (100 grams)
  • 1/2 teaspoon ground cinnamon (optional)
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, cold and cubed (115 grams or 1 stick)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease your 9-inch baking dish to prevent sticking.
  2. In a large bowl, combine the chopped rhubarb, granulated sugar, all-purpose flour, cinnamon (if using), and vanilla extract. Stir gently but thoroughly to coat the rhubarb evenly. Set aside.
  3. In a separate bowl, mix rolled oats, flour, brown sugar, cinnamon, and salt. Add the cold, cubed butter. Using a pastry cutter or two forks, cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized pieces.
  4. Transfer the rhubarb filling into the prepared baking dish and spread evenly. Sprinkle the oat streusel topping evenly over the rhubarb, covering it completely.
  5. Place the dish on the middle rack of your preheated oven. Bake for 40-45 minutes or until the topping is golden brown and the filling is bubbling around the edges. If the topping browns too fast, tent with foil.
  6. Let the rhubarb crisp rest for 10-15 minutes after baking before serving.

Notes

Use cold butter for the streusel topping to keep it crumbly and crunchy. If rhubarb is too tart, sprinkle a little sugar on top before serving. Frozen rhubarb can be used if thawed and drained. For gluten-free, substitute flours and use certified gluten-free oats. Variations include adding berries or nuts to the topping.
