Ingredients You’ll Need:
For the Crust and Streusel Topping:
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/4 teaspoon salt
- 3/4 cup unsalted butter , cold and cubed
For the Rhubarb Filling:
- 3 cups diced fresh rhubarb (about 1/2-inch pieces)
- 1 cup granulated sugar
- 1/4 cup cornstarch
- 1/4 cup water
- 1 tablespoon lemon juice (to balance tartness)
- 1 teaspoon vanilla extract (optional, for added sweetness)
Step-by-Step Instructions:
Step 1: Preheat and Prep
- Preheat your oven to 350°F (175°C) . Line an 8x8-inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the parchment paper.
Step 2: Make the Crust and Streusel
- In a mixing bowl, combine the flour, sugar, and salt. Add the cold, cubed butter and use a pastry cutter or your fingers to blend until the mixture resembles coarse crumbs.
- Reserve 1 cup of the mixture for the streusel topping. Press the remaining mixture evenly into the bottom of the prepared pan to form the crust.
Step 3: Prepare the Rhubarb Filling
- In a saucepan, combine the diced rhubarb, sugar, cornstarch, water, and lemon juice. Cook over medium heat, stirring frequently, until the mixture thickens and the rhubarb softens (about 8–10 minutes ).
- Remove from heat and stir in the vanilla extract, if using. Let the filling cool slightly before spreading it over the crust.
Step 4: Assemble and Bake
- Spread the rhubarb filling evenly over the crust. Sprinkle the reserved streusel topping over the filling, pressing lightly to help it adhere.
- Bake in the preheated oven for 35–40 minutes , or until the topping is golden brown and the filling is bubbling around the edges.
Step 5: Cool and Serve
- Allow the bars to cool completely in the pan on a wire rack. This helps the filling set and makes slicing easier.
- Once cooled, lift the bars out of the pan using the parchment paper overhang. Cut into squares or rectangles and serve.
