Equipment

  • 2-quart baking dish
  • mixing bowls
  • measuring cups and spoons
  • knife and cutting board

Ingredients

  • 2 lb rhubarb, sliced
  • 1/4 cup cornstarch
  • 3/4 cup granulated sugar
  • 1/2 tsp cinnamon
  • 1 cup quick oats
  • 1/2 cup all-purpose flour
  • 1/2 cup granulated sugar (for topping)
  • 1/2 tsp cinnamon (for topping)
  • 1 pinch salt
  • 1/2 cup cold butter, cubed

Instructions

  • Preheat the oven to 400°F (200°C) and lightly butter a 2-quart baking dish.
  • In a large bowl, combine sliced rhubarb, cornstarch, sugar, and cinnamon. Toss well and transfer to the baking dish.
  • In another bowl, mix oats, flour, sugar, cinnamon, and salt.
  • Add cold cubed butter and work it into the mixture using your fingers until clumps form and the texture is crumbly.
  • Sprinkle the crumble topping evenly over the rhubarb filling without pressing it down.
  • Bake for 35 minutes until the topping is golden brown and the filling is bubbling.
  • Let the crisp rest for 10 minutes before serving. Serve warm with ice cream or whipped cream.

Notes

Let the crisp rest for at least 10 minutes before serving to allow the filling to set properly. Use fresh or fully thawed and drained frozen rhubarb. For extra flavor, try adding strawberries or a touch of vanilla to the filling.
