Ingredients
- 2 cups all-purpose flour, divided
- 1/2 cup powdered sugar
- 1 cup unsalted butter, softened
- 4 large eggs
- 2 cups granulated sugar
- 1/2 teaspoon salt
- 1/4 cup all-purpose flour (for the filling)
- 4 cups fresh rhubarb, chopped into 1/2-inch pieces
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking pan or line it with parchment paper for easy removal.
- In a medium bowl, combine 2 cups of flour and the powdered sugar. Cut in the softened butter using a pastry cutter or a fork until the mixture resembles coarse crumbs.
- Press the crust mixture firmly and evenly into the bottom of the prepared baking pan.
- Bake the crust for 12 to 15 minutes, or until it is just lightly golden around the edges.
- While the crust is baking, prepare the filling by whisking the eggs in a large bowl until well beaten.
- Add the granulated sugar, 1/4 cup of flour, and salt to the eggs, whisking until the mixture is smooth and well combined.
- Gently fold the chopped rhubarb into the egg mixture until the pieces are evenly coated.
- Pour the rhubarb mixture over the hot, pre-baked crust and spread it out evenly.
- Return the pan to the oven and bake for an additional 35 to 40 minutes, or until the filling is set and the top is lightly browned.
- Remove from the oven and allow the bars to cool completely in the pan on a wire rack before slicing into squares.
Expert Tips / Pro Tips
To get the best results with your Rhubarb Dream Bars, make sure your rhubarb is sliced into small, uniform pieces. This ensures that the fruit softens properly during the baking process and distributes evenly throughout the custard. If your rhubarb is particularly thick, slice the stalks lengthwise before chopping. Additionally, do not be tempted to slice the bars while they are still warm; cooling them completely is essential for the custard to set properly, ensuring clean, beautiful squares.
Variations & Substitutions
If you find yourself short on rhubarb, you can easily substitute half of the rhubarb with sliced strawberries to create a classic Strawberry Rhubarb Dream Bar. For those who enjoy a bit of spice, adding a half teaspoon of ground ginger or cardamom to the filling can add a wonderful depth of flavor. If you need a gluten-free version, a high-quality 1:1 gluten-free flour blend can be used in both the crust and the filling with excellent results.
Serving Suggestions
These bars are delicious on their own, but a light dusting of powdered sugar right before serving adds a beautiful finishing touch. For a more decadent dessert, serve a square of Rhubarb Dream Bars with a dollop of fresh whipped cream or a scoop of premium vanilla bean ice cream. They are also a wonderful addition to a brunch spread or a garden tea party.
Storage, Freezing & Reheating
Store any leftover bars in an airtight container in the refrigerator for up to 4 days. Because of the custard-like filling, they stay freshest when kept chilled. If you wish to freeze them, wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag for up to 3 months. Thaw the bars in the refrigerator overnight before serving. Reheating is generally not recommended as these bars are best enjoyed cold or at room temperature.

FAQ
Can I use frozen rhubarb for this recipe?
Yes, you can use frozen rhubarb. Be sure to thaw it completely and drain off any excess liquid before folding it into the filling mixture to prevent the bars from becoming soggy.
Do I need to peel the rhubarb first?
No, there is no need to peel rhubarb for this recipe. The skin softens during baking and provides that beautiful pink color characteristic of rhubarb desserts.
How do I know when the bars are finished baking?
The bars are done when the edges are golden brown and the center no longer jiggles when the pan is gently shaken. The top should have a slight parchment-like crust.
Can I make the crust in a food processor?
Absolutely! You can pulse the flour, powdered sugar, and cold butter in a food processor until it forms a crumbly dough, then press it into the pan as directed.
