Ingredients

Scale
  • 4 cups fresh rhubarb, chopped (about 500g / 1.1 lbs)
  • 3/4 cup granulated sugar (150g)
  • 2 tablespoons all-purpose flour (15g)
  • 1/2 cup unsalted butter, browned (115g / 1 stick)
  • 1 cup old-fashioned rolled oats (90g)
  • 1/2 cup light brown sugar, packed (100g)
  • 1/2 cup all-purpose flour (60g)
  • 1 teaspoon ground cinnamon
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 9×9-inch baking dish with butter or non-stick spray.
  2. In a medium bowl, combine chopped rhubarb, granulated sugar, and 2 tablespoons all-purpose flour. Toss gently to coat evenly.
  3. Spread the rhubarb mixture evenly into the prepared baking dish and set aside.
  4. Melt the unsalted butter in a medium saucepan over medium heat. Stir frequently until the butter foams and turns a deep golden brown with a nutty aroma (about 4-5 minutes). Remove from heat immediately.
  5. In a large bowl, combine rolled oats, light brown sugar, 1/2 cup all-purpose flour, ground cinnamon, and salt. Pour the warm brown butter and vanilla extract over the dry ingredients and stir until the mixture resembles coarse crumbs.
  6. Sprinkle the oat streusel topping evenly over the rhubarb filling, covering all exposed fruit.
  7. Bake in the preheated oven for 35-40 minutes, or until the topping is golden brown and the rhubarb filling is bubbling around the edges.
  8. Remove from oven and let cool on a wire rack for at least 15 minutes before serving.

Notes

Use a light-colored pan to brown butter to monitor color changes and avoid burning. If topping browns too quickly, tent with foil halfway through baking. Let crisp cool for at least 15 minutes to thicken juices before serving. For gluten-free, substitute all-purpose flour with gluten-free baking blend and use certified gluten-free oats. Vegan butter can be used for dairy-free adaptation.
