Directions

  1. 1

    Preheat your oven to 400°F and grease a 9×13 inch baking dish. Slice the rhubarb into 1/2-inch thick pieces, zest and juice the lemon, and cut the cold butter for the base into 1/2-inch cubes to prepare for assembly.

  2. 2

    In a medium bowl, whisk together the flour, baking powder, and salt. Add the cold butter cubes and mix with fingertips until coarse breadcrumbs form. Stir in the egg and 1/2 cup sugar until just combined. Press the mixture firmly into the bottom of the prepared baking dish to form an even layer.

  3. 3

    In a large saucepan over medium-high heat, combine sliced rhubarb, 1/2 cup sugar, lemon zest, and lemon juice. Stir occasionally and let it cook for 3-4 minutes until rhubarb softens and releases juices. Sprinkle cornstarch while stirring constantly, then simmer for 5 more minutes until thick and glossy. Remove from heat and let cool for 5 minutes.

  4. 4

    In a small bowl, mix oats, 1/2 cup sugar, vanilla sugar, cinnamon, and melted butter until coated. Pour cooled rhubarb filling evenly over the base crust. Sprinkle the crumble topping evenly over the filling, pressing down slightly to secure.

  5. 5

    Bake the bars at 400°F for 20-25 minutes until topping is golden brown and filling bubbles at edges. Remove from oven and cool on a wire rack for 15-20 minutes before cutting into 16 squares. This helps the bars set and hold shape when sliced.
