Make this easy rhubarb crisp for a perfect balance of sweet and tart flavors. The buttery oat topping stays crunchy, making this a comforting spring dessert.

Ingredients

Scale
  • 4 cups fresh rhubarb, chopped
  • 1 cup granulated sugar (adjust based on rhubarb tartness)
  • 2 tablespoons all-purpose flour
  • 1 teaspoon vanilla extract
  • 1/2 cup all-purpose flour (for topping)
  • 1/2 cup rolled oats
  • 1/2 cup packed light brown sugar
  • 1/4 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup (1 stick) cold unsalted butter, cut into small pieces

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch baking dish.
  2. In a medium bowl, combine the chopped rhubarb, granulated sugar, 2 tablespoons of flour, and vanilla extract. Toss gently to coat. Pour this filling mixture into the prepared baking dish.
  3. In a separate bowl, prepare the topping. Combine the remaining 1/2 cup flour, rolled oats, brown sugar, cinnamon, and salt. Mix these dry ingredients well.
  4. Cut in the cold butter pieces using a pastry blender or your fingertips until the mixture resembles coarse crumbs. Do not overmix; you want distinct buttery pieces.
  5. Sprinkle the oat topping evenly over the rhubarb filling in the baking dish. Press lightly.
  6. Bake for 35 to 45 minutes, or until the topping is golden brown and the fruit filling is bubbling thickly around the edges.
  7. Let the crisp cool for at least 15 minutes before serving. This allows the filling to set properly.

Notes

  • For a Strawberry Rhubarb Crisp Variation, substitute 2 cups of the rhubarb with 2 cups of fresh or frozen strawberries.
  • If you prefer a richer topping flavor, use brown butter instead of cold butter in the topping mixture.
  • Serve this comfort food dessert warm with vanilla ice cream for the best experience.
