Ingredients
- 1 cup all-purpose flour: The foundation of the crust, providing a tender, flaky base.
- 1/2 cup cold butter, cubed: Adds a rich, buttery flavor that melts in your mouth.
- 2 tbsp sugar: Balances the tartness of the rhubarb with a touch of sweetness.
- 2 large eggs: Essential for the custard, adding richness and helping set the filling.
- 1 cup sugar: Sweetens the custard, complementing the flavors of the rhubarb.
- 1/4 cup all-purpose flour: Thickens the custard for a creamy texture.
- 1/4 tsp salt: Enhances the overall flavor profile of the bars.
- 2 cups chopped rhubarb: The star ingredient, providing a burst of juicy tartness.
Step-by-Step Directions
Preheat the Oven: Begin by setting your oven to 350°F (175°C), allowing it to preheat while you prepare the crust.
Make the Crust: In a mixing bowl, combine the 1 cup of all-purpose flour, 1/2 cup cubed cold butter, and 2 tablespoons of sugar. Use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs.
Press the Crust: Take the crumbly mixture and press it firmly into the bottom of a greased 8×8-inch baking pan. Ensure it is evenly distributed across the base.
Bake the Crust: Place the pan in the preheated oven and bake for 12–15 minutes, or until the crust is lightly golden. Remove from the oven and let it cool slightly.
Prepare the Filling: In another bowl, whisk together the 2 large eggs, 1 cup of sugar, 1/4 cup of flour, and 1/4 teaspoon of salt until well combined and smooth.
Fold in Rhubarb: Gently fold in the 2 cups of chopped rhubarb, ensuring that the fruit is evenly coated in the custard mixture.
Assemble and Bake: Pour the rhubarb custard filling over the hot crust in the baking pan. Return the pan to the oven and bake for an additional 35–40 minutes, or until the filling is set and no longer jiggles.
Cool and Slice: Once baked, allow the bars to cool completely in the pan. Once cooled, slice them into squares. If desired, dust with powdered sugar before serving.
Tips & Tricks
- Use Fresh Rhubarb: Opt for fresh rhubarb for the best flavor. If you only have frozen rhubarb, ensure it is thoroughly thawed and drained to avoid excess liquid in the bars.
- Storage: Keep the bars stored in an airtight container at room temperature for up to three days, or in the fridge for a week.
- Add Zest: For a zesty twist, consider adding some lemon or orange zest to the custard mixture for a bright flavor contrast.
- Thicker Filling: If you prefer a thicker custard, add an extra egg or an additional tablespoon of flour to the filling mixture.
