How to Make Rhubarb Custard Bars
Preheat your oven to 350ºF (180ºC) and prepare an 8 or 9-inch square baking dish by lining it with parchment paper. This will ensure an easy release once your bars are baked.
Beat together the softened butter and ¼ cup sugar in a mixing bowl until the mixture is light and fluffy, about 1 to 2 minutes. This creates a delightful base for your crust!
Combine the 1 ¼ cups of all-purpose flour and ¼ teaspoon salt with the butter mixture. Mix on low speed until the dough is crumbly and no visible flour remains, bringing the crust together.
Spread the dough crumbs evenly into the prepared baking dish. Use your hands to press the crust firmly into an even layer, ensuring it will hold together nicely.
Bake the crust for 24 to 26 minutes or until the edges turn slightly golden. Once baked, remove it from the oven and cool it on a wire rack to prevent it from becoming soggy.
Prepare the custard while the crust is cooling. In the same mixing bowl, combine ¾ cup sugar, 1 egg, and 2 egg yolks. Mix until the combination is smooth and creamy.
Add ¼ cup all-purpose flour and ¼ teaspoon salt to the egg mixture and continue mixing until there are no streaks of flour visible, scraping down the sides of the bowl as needed.
Fold in the 3 cups of chopped rhubarb gently into the custard mixture until each piece is well coated. This is where the vibrant flavor of rhubarb will shine through!
Pour the rhubarb custard mixture over the pre-baked shortbread crust. Use a rubber spatula or fork to spread the rhubarb into an even layer, evenly distributing those delicious pieces.
Bake the rhubarb custard bars for 42 to 45 minutes, or until the custard is set and firm to the touch. Let them cool completely before slicing to ensure perfect bars.
Optional: Serve with a dusting of powdered sugar for an elegant touch.

Rhubarb Custard Bars Recipe FAQs
How do I choose the right rhubarb?
Absolutely! When selecting rhubarb, look for firm, glossy stalks that are bright pink or red in color.

If using frozen, make sure it’s fully thawed and drained to avoid excess liquid.
What is the best way to store leftover rhubarb custard bars?
The more the merrier! To store your leftover bars, place them in an airtight container at room temperature for up to 3 days.

What should I do if my custard isn’t setting properly?
