Preheat oven to 375°F (190°C). Line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy lifting. This ensures your Easy Rhubarb Bars with Buttery Crust won't stick and are simple to remove.

In a large bowl, combine 2 1/2 cups all-purpose flour, 1 cup granulated sugar, and 1/2 tsp salt. Cut in 1 cup (2 sticks) cold and cubed unsalted butter using a pastry blender or your fingertips until coarse crumbs form.
03 -
Reserve about 1 cup of the crumb mixture for the topping. Press the remaining crumb mixture evenly into the bottom of the prepared 9x13-inch pan. This forms the sturdy base for your delicious Easy Rhubarb Bars with Buttery Crust.

In a separate large bowl, gently toss 6 cups fresh rhubarb (chopped into 1/2-inch pieces) with 1 1/2 cups granulated sugar, 1/4 cup cornstarch, 2 tbsp fresh lemon juice, 1 tsp vanilla extract, and a pinch of salt until well combined.

Pour the rhubarb filling evenly over the pressed crust in the pan. Crumble the reserved 1 cup of buttery crust mixture over the top of the rhubarb filling. Spread it out as evenly as possible.
06 -
Bake for 40-45 minutes, or until the topping is golden brown and the rhubarb filling is bubbly. The perfect bake ensures the best texture for your Easy Rhubarb Bars with Buttery Crust.

Let the bars cool completely in the pan on a wire rack before lifting them out using the parchment paper overhang. Once cooled, dust generously with 2 tbsp powdered sugar before cutting into 16 squares and serving.
