- Salt – Enhances flavors in both crust and custard; essential for balancing sweetness.
- Butter – Creates a rich, flaky crust; ensure it is cold for best results.
For the Custard
- Eggs – Binds the custard and contributes to its creamy texture; essential for achieving that delightful creaminess.
- Milk or Cream – Adds richness to the custard; whole milk or cream is preferable for a decadent flavor.

Step‑by‑Step Instructions for Rhubarb Custard Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, line a 9×13 inch baking pan with parchment paper or grease it well to prevent sticking. This preparation is crucial for ensuring your Rhubarb Custard Bars bake evenly and can be easily removed later.
Step 2: Make the Crust
In a mixing bowl, combine flour, sugar, and a pinch of salt. Add cold butter, cutting it in with a pastry cutter or your fingertips until the mixture resembles coarse crumbs. Press this crumbly mixture evenly into the bottom of the prepared pan and bake for 12-15 minutes until the crust is set and lightly golden.
Step 3: Prepare the Custard
While the crust is baking, whisk together eggs, sugar, milk or cream, vanilla extract, flour, and salt in a large bowl until smooth and creamy. Take care to mix well, ensuring there are no lumps. Once blended, gently fold in the chopped rhubarb, distributing it evenly throughout the custard mixture for a burst of flavor in each bite.
Step 4: Bake the Custard Layer
As soon as the crust is ready, pour the custard mixture over the warm crust. This helps to create a nice texture. Carefully place the pan back in the oven and bake for 35-45 minutes. You’ll know it’s done when the custard is set but still has a soft jiggle in the center—this is key to achieving that creamy consistency.
Step 5: Cool and Chill
Once baked, remove the Rhubarb Custard Bars from the oven and allow them to cool at room temperature for about 30 minutes. Once cooled, place the pan in the refrigerator for several hours, preferably until chilled. This chilling step is essential for achieving clean, precise slices when serving.
Step 6: Slice and Serve
After chilling, carefully lift the bars out of the pan using the parchment paper. Use a sharp knife to slice into squares or bars. The beautiful contrast of the creamy custard and tart rhubarb should be visible. Serve these delightful Rhubarb Custard Bars at your next gathering and watch them disappear!
Make Ahead Options
These Rhubarb Custard Bars are a fantastic choice for busy home cooks looking to save time without sacrificing flavor! You can prepare the crust up to 3 days in advance; simply bake, then let it cool completely before wrapping it tightly in plastic wrap and refrigerating. The custard filling can also be mixed and stored in the refrigerator for up to 24 hours—just keep the chopped rhubarb separate until you’re ready to bake to prevent unwanted moisture. When you’re ready to serve, pour the custard over the crust, bake as instructed, and chill the finished bars. This way, you’ll achieve perfect creamy bars that are just as delicious, making your baking experience seamless!
Expert Tips for Rhubarb Custard Bars
-
Chill Before Cutting: Allow the bars to cool completely before refrigerating. This step helps achieve clean cuts and enhances flavor development.
-
Uniform Rhubarb Pieces: Ensure your chopped rhubarb pieces are even in size. This ensures that they bake uniformly, giving you a consistent texture in every bite.
-
Beware of Watery Filling: Avoid adding too much rhubarb; excess moisture can make the custard soggy. Stick to the recommended amount for the best results.
-
Check Doneness Carefully: When baking your Rhubarb Custard Bars, keep an eye on the custard. It should be set with a slight jiggle—this indicates a creamy texture.
-
Customize Your Flavors: Feel free to experiment! Adding a touch of orange zest or mixing in strawberries can elevate the flavors and bring a personal twist to your creamy dessert.

Thawing: When ready to enjoy, simply thaw the bars in the fridge overnight or leave them at room temperature for a couple of hours before serving.
Reheating: If you prefer them warm, gently reheat in the oven at a low temperature for about 10 minutes, ensuring they don’t dry out.

Rhubarb Custard Bars Recipe FAQs
What should I look for when selecting rhubarb?
Absolutely! When choosing rhubarb, you want to look for firm, crisp stalks that are a vibrant pink or red color. Avoid any stalks that have dark spots, soft spots, or appear wilted, as this indicates they are past their prime.
How do I store leftover Rhubarb Custard Bars?
Very! Store your Rhubarb Custard Bars in an airtight container in the refrigerator for up to 4 days. Make sure they are fully cooled before covering them to keep that creamy texture intact. If you have a lot left, freezing is also a great option!
Can I freeze Rhubarb Custard Bars?
Absolutely! To freeze, slice the bars into individual portions, then wrap each slice tightly in plastic wrap. Place the wrapped slices in a freezer-safe bag or container. They can stay deliciously fresh in the freezer for up to 2 months. When you’re ready to enjoy them, thaw in the fridge overnight or at room temperature for a couple of hours.
What if my custard isn’t set after baking?
No worries! If your custard isn’t set after the recommended baking time, return it to the oven and bake for an additional 5 to 10 minutes. The center should jiggle slightly but should not be liquid. If you find it still runny even after this time, check to see if you’ve measured your ingredients accurately—overly wet or undercooked rhubarb can affect the custard’s consistency.
Are Rhubarb Custard Bars safe for pets?
Very! Rhubarb leaves are toxic to pets, so always ensure that only the stalks are used in this recipe. Additionally, if your pet has any dietary restrictions or allergies, it’s best to keep them away from these sweet treats as they contain eggs and dairy.
Can I adjust the sugar content in the custard?
Definitely! If you prefer a less sweet filling, feel free to reduce the sugar in the custard by a couple of tablespoons. This is also a great option if you’re incorporating sweeter fruits, like strawberries, as they will add natural sweetness to the bars while maintaining that creamy rich flavor.
