A golden crunch on top, and sweet-tart rhubarb perfection on the bottom. Best served with vanilla ice cream.

Ingredients

  • 1 cup large-flake oats

  • 3/4 cup all-purpose flour

  • 1/2 cup packed brown sugar

  • 3/4 tsp salt

  • 1/2 cup cold unsalted butter, cubed

Filling

  • 6 cups chopped rhubarb, cut into 1-in. pieces (about 760 g)

  • 1 cup granulated sugar

  • 1/3 cup cornstarch

  • 2 tbsp water

Instructions

  • POSITION rack in lower third of oven and preheat to 350F.

  • TOPPING: Stir oats, flour, brown sugar and salt in a bowl. Add butter and work in, using your fingertips, until crumbly. Refrigerate until ready to use.

  • FILLING: Toss rhubarb, sugar, cornstarch and water in a large bowl, stirring until cornstarch is absorbed. Let sit 5 min and stir again. Transfer to a 9 x 13-in. glass baking dish.
