How to Make Rhubarb Custard Bars
Preheat the Oven: Begin by setting your oven to 350ºF (180ºC). Don’t forget to line an 8 or 9-inch square baking dish with parchment paper for easy removal later!
Cream the Butter and Sugar: In a mixing bowl, beat together the butter and ¼ cup sugar until light and fluffy, about 1 to 2 minutes. This will create a wonderfully rich base for your crust.
Add Flour and Salt: Gently incorporate 1 ¼ cups of all-purpose flour and ¼ teaspoon salt into the mixture. Mix on low speed until it resembles a crumbly dough with no visible flour left.
Form the Crust: Dump the crumbly dough into your prepared baking dish. Use your fingers to spread and press it evenly into the pan, creating a tightly packed shortbread layer that will hold everything together.
Bake the Crust: Pop the crust into your preheated oven and bake for 24 to 26 minutes or until the edges are slightly golden. Once baked, let it cool on a wire rack.
Prepare the Custard Mixture: While your crust is cooling, use the same mixing bowl to combine ¾ cup sugar, 1 large egg, and 2 egg yolks. Mix on low speed until everything is nicely blended and smooth.
Incorporate Flour and Salt: Add ¼ cup of all-purpose flour and ¼ teaspoon salt into the custard mixture. Keep mixing on low until no streaks of flour remain. Remember to scrape down the sides halfway through!
Fold in the Rhubarb: Gently add your chopped rhubarb to the custard and fold it in carefully. Ensure every piece is well coated for that delightful burst of flavor in each bite.
Pour and Spread: Pour the rhubarb custard mixture over your pre-baked crust. Use a rubber spatula to spread it evenly, ensuring a smooth layer that looks as good as it tastes.
Bake It All Together: Return the baking dish to the oven and bake your rhubarb custard bars for 42 to 45 minutes, or until the custard is set and slightly firm. Once done, let it cool completely on a wire rack before slicing.
Optional: Dust with powdered sugar before serving for an elegant touch!

Expert Tips for Rhubarb Custard Bars
Choosing Rhubarb: Select bright red rhubarb stalks for a sweeter taste. Avoid overly fibrous or wilted pieces for the best texture in your rhubarb custard bars recipe.
Crust Consistency: Ensure your crust is evenly packed in the pan. If it’s too crumbly before baking, it may not hold together well later.
Egg Temperature: Using room temperature eggs will help them blend seamlessly into the custard mixture, providing an extra smooth texture.
Watch Your Baking Time: Ovens can vary, so keep an eye on your bars towards the end of the baking time. Overbaking can lead to a tough custard.
Cool Completely: Allow the bars to cool fully on a wire rack before slicing. This helps the custard set properly and makes cutting easier.

Rhubarb Custard Bars Recipe FAQs
How do I choose the right rhubarb?
Absolutely! When selecting rhubarb for the rhubarb custard bars recipe, look for bright red stalks rather than green ones; they tend to be sweeter and less fibrous. Avoid stalks that appear wilted or have dark spots, as these can affect the texture and taste of your bars.
What’s the best way to store rhubarb custard bars?
You can store the bars in an airtight container in the fridge for up to 4 days, keeping them fresh while preserving that luscious custard texture. For room temperature storage, they’ll only last about 1 day—make sure to cover them to prevent drying out!
Can I freeze rhubarb custard bars?
Very! To freeze your rhubarb custard bars, wrap each bar tightly in plastic wrap and then in aluminum foil, ensuring they’re sealed well to prevent freezer burn. They’ll stay delightful in the freezer for up to 3 months. To enjoy, simply let them thaw in the fridge overnight before reheating or enjoying cold.
What if my custard doesn’t set properly?
If your custard isn’t setting, it may need more time in the oven. Ovens can vary, so I recommend checking it towards the end of the cooking time. If it appears too runny, give it an additional 5-10 minutes of baking. Remember that the custard should be slightly firm to the touch when done, so patience is key!
Can I make this recipe gluten-free?
Absolutely! You can substitute the all-purpose flour with a gluten-free blend that’s designed for baking. Just be sure to check the mix is suitable for desserts, and remember that the texture might be a bit different, but the flavor of the rhubarb custard bars will still shine through beautifully!
