Rhubarb Custard Bars

Step-by-Step Instructions:

Step 1: Preheat and Prep
Preheat your oven to 350°F (175°C) . Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the parchment paper.

Step 2: Make the Shortbread Crust
In a mixing bowl, combine the flour, softened butter, sugar, and a pinch of salt. Use your fingers or a pastry cutter to mix until the dough comes together in a crumbly texture.
Press the dough evenly into the bottom of the prepared pan to form the crust.
Bake the crust for 15–18 minutes , or until lightly golden around the edges. Remove from the oven and let it cool slightly while you prepare the filling.

Step 3: Make the Rhubarb Filling
In a medium saucepan, combine the diced rhubarb, sugar, and water. Cook over medium heat, stirring occasionally, until the rhubarb softens and breaks down, about 8–10 minutes .

In a small bowl, whisk the cornstarch with 2 tablespoons of cold water to create a slurry. Stir the slurry into the rhubarb mixture and cook for another 2–3 minutes , until thickened. Remove from heat and set aside to cool slightly.

Step 4: Make the Custard Layer
In a mixing bowl, whisk together the eggs, sugar, flour, and vanilla extract until smooth and well combined.

Step 5: Assemble the Bars
Spread the cooled rhubarb filling evenly over the baked crust.
Pour the custard mixture over the rhubarb layer, spreading it gently to cover the filling completely.

Step 6: Bake Until Set
Bake the bars for 30–35 minutes , or until the custard layer is set and the top is lightly golden. A toothpick inserted into the center should come out clean or with a few moist crumbs.
Remove from the oven and let the bars cool completely in the pan on a wire rack.

Step 7: Chill and Slice
Once cooled, refrigerate the bars for at least 2 hours (or overnight) to allow them to set fully.
Use the parchment paper overhang to lift the bars out of the pan. Cut into squares or rectangles for serving.
