Ingredients:
For the crust:
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
For the rhubarb filling:
- 2 cups fresh rhubarb, chopped into small pieces
- 3/4 cup granulated sugar
- 2 tablespoons cornstarch
- 1/4 teaspoon vanilla extract
- 1/2 cup white chocolate chips
For the topping:
- 1/2 cup white chocolate chips, melted (for drizzling)

Instructions:
- Prepare the Crust: Preheat your oven to 350°F (175°C) and grease or line an 8×8-inch baking pan with parchment paper. In a medium bowl, mix the flour, sugar, and salt. Cut in the softened butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Press the mixture evenly into the prepared pan to form the crust.
- Bake the Crust: Bake the crust for 12-15 minutes, or until it is golden brown and firm. Once baked, remove from the oven and let it cool slightly.
- Make the Rhubarb Filling: In a saucepan, combine the chopped rhubarb, sugar, and cornstarch. Cook over medium heat, stirring occasionally, until the rhubarb breaks down and the mixture thickens, about 10 minutes. Remove from heat and stir in vanilla extract.
- Assemble the Bars: Spread the rhubarb filling evenly over the cooled crust. Then, sprinkle the white chocolate chips evenly over the top of the rhubarb filling.
- Create the Swirl: Using a spoon or knife, swirl the rhubarb and white chocolate together to create a marbled effect.
- Bake the Bars: Return the pan to the oven and bake for an additional 20-25 minutes, or until the filling is set and the edges are golden.
- Drizzle with White Chocolate: Once the bars are baked and cooled, drizzle the melted white chocolate over the top to add a final touch of sweetness.
- Cool and Serve: Allow the bars to cool completely in the pan before cutting into squares. Serve and enjoy!
