Ingredients

Filling

  • 5-6 cups chopped rhubarb fresh or frozen (about 6 stalks)
  • 3/4 cup granulated sugar (150g)

Instructions

  • Preheat oven to 375°F.
  • Combine the rhubarb, sugar, cornstarch and lemon juice in an 8×8 or 9×9 baking dish. Toss to evenly distribute the sugar and cornstarch with the rhubarb.

  • In a large bowl, mix the butter into the brown sugar, oats, flour, cinnamon, and salt using a fork or your hands until it resembles pea-sized crumbs. Add chopped nuts, if using.
