If you prefer a dairy-free option, swap heavy cream with full-fat coconut milk, though it may add a mild coconut flavor.

Step-by-Step Instructions for Rhubarb Bars with Shortbread Crust

1. Preheat your oven to 350°F (175°C) and line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal. This ensures your Rhubarb Bars with Shortbread Crust lift out cleanly after baking.
2. In a mixing bowl, combine flour, confectioners’ sugar, and salt. Add melted butter and mix until a soft dough forms. Press the mixture evenly into the prepared pan to create a smooth crust layer.
3. Bake the shortbread crust for 10–12 minutes, or until it turns lightly golden. Avoid overbaking, as this can make the crust too hard.
4. While the crust bakes, prepare the filling. In a large bowl, whisk together sugar, flour, and salt. Add eggs and heavy cream, mixing until smooth and well combined.
5. Stir in the chopped rhubarb, ensuring it is evenly distributed throughout the mixture. This step is essential for consistent flavor in every bite of your Rhubarb Bars with Shortbread Crust.
6. Pour the rhubarb filling over the partially baked crust and spread it evenly. Return the pan to the oven and bake for about 20 minutes.
7. Meanwhile, prepare the crumble topping. Combine flour, oats, and brown sugar in a bowl. Add cold butter and work it into the mixture using your fingers or a pastry cutter until crumbly.
8. Remove the pan from the oven and sprinkle the crumble topping evenly over the filling. This layer adds texture and a slightly crisp finish.
9. Return the pan to the oven and bake for another 25–30 minutes, or until the filling is set and no longer jiggles in the center.
10. Allow the bars to cool at room temperature, then refrigerate until fully chilled. This step is crucial for clean slicing and the best texture.
11. Once cooled, lift the bars out using the parchment paper and cut into squares. Your Rhubarb Bars with Shortbread Crust are now ready to serve.

Tips & Tricks for Perfect Rhubarb Bars with Shortbread Crust

To achieve the best results, avoid overworking the shortbread dough, as this can make the crust tough instead of tender. Press it gently and evenly into the pan.

Cut the rhubarb into small, uniform pieces to ensure even cooking and a consistent texture. If using frozen rhubarb, always drain excess moisture to prevent soggy bars.

Keep the butter cold when making the crumble topping. This helps create a light, crisp texture rather than a dense layer.

Finally, be patient during cooling. Proper chilling allows the filling to set fully, making your Rhubarb Bars with Shortbread Crust easier to slice and more enjoyable to eat.
