How to Make Rhubarb Custard Bars
-
Preheat the Oven: Start by preheating your oven to 350°F (175°C). This important step ensures your bars bake evenly and achieve a lovely golden color.
-
Prepare the Crust: In a mixing bowl, combine 1 cup of all-purpose flour and 1/2 cup of powdered sugar. Cut in 1/2 cup of cold unsalted butter until the mixture resembles coarse crumbs. Pack it tightly into a greased 9×13-inch baking pan, creating a solid base. Bake for 15-20 minutes until it’s lightly golden.
-
Prepare the Filling: Once the crust has cooled slightly, spread 2 cups of chopped fresh rhubarb evenly over it. In another bowl, whisk together 3/4 cup of granulated sugar, 2 tablespoons of flour, 2 large eggs, 1/4 teaspoon of salt, and 1 teaspoon of vanilla extract until the mixture is smooth. Pour this custard mixture over the rhubarb layer, covering it completely.
-
Bake the Bars: Return the pan to the oven and bake for 35-45 minutes until the custard is set and lightly golden on top. Keep an eye on it; you want it firm and not jiggly.
-
Cool and Slice: Once baked, allow the bars to cool completely in the pan. After cooling, lift them out using the parchment overhang, and cut into squares for serving.
Optional: Dust with powdered sugar for an elegant finish.

Make Ahead Options
These Rhubarb Custard Bars are perfect for making ahead to save time during busy weeks! You can prepare the shortbread crust up to 24 hours in advance; just store it tightly wrapped in plastic wrap in the refrigerator to maintain its freshness. The filling can also be mixed and stored separately for up to 3 days, but it’s best to incorporate the filling right before baking to prevent any sogginess. When you’re ready to bake, simply pour the filling over the crust and bake as directed. This method ensures you enjoy that delightful texture and flavor, making it just as delicious even when prepped ahead!

Freezer: To freeze, wrap the bars tightly in plastic wrap and place them in a freezer-safe container. They can be frozen for up to 3 months, making them a convenient make-ahead treat.
