Step 3: Prepare the Rhubarb Custard Filling
- In a large mixing bowl, whisk together the sugar, eggs, flour, and cornstarch until smooth.
- Stir in the heavy cream and vanilla extract until fully combined.
- Gently fold in the diced rhubarb until evenly coated in the custard mixture.
Step 4: Assemble and Bake
- Pour the rhubarb custard filling evenly over the pre-baked crust, spreading it out gently with a spatula.
- Sprinkle the top with ground cinnamon, if desired, for a hint of spice.
- Bake the bars for 35–40 minutes , or until the custard is set and the top is lightly golden. A toothpick inserted into the center should come out clean or with just a few moist crumbs.
Step 5: Cool and Serve
- Allow the bars to cool completely in the pan on a wire rack. Once cooled, refrigerate for at least 1–2 hours to firm up before slicing.
- Use the parchment paper overhang to lift the bars out of the pan. Cut into squares or rectangles.
- Dust with powdered sugar just before serving, if desired.
