Rhubarb Custard Bars Ingredients
• Here’s everything you need to make delightful Rhubarb Custard Bars!
For the Filling
- Fresh Rhubarb (2 cups, chopped) – Provides tartness; frozen rhubarb can be used after thawing and draining moisture.
- Granulated Sugar (1 cup, divided) – Adds sweetness; for a sweeter custard, consider increasing sugar by 1/4 cup.
- Ground Cinnamon (1/2 teaspoon) – Adds warmth and depth to the filling.
- Whole Milk (1 cup) – Creates a creamy custard; half-and-half can be substituted for a richer texture.
- Large Eggs (3) – Binds the custard; replace with flax eggs if desired (1 tbsp ground flaxseed + 3 tbsp water per egg).
- Vanilla Extract (1 teaspoon) – Enhances the flavor depth of the custard.
For the Crust
- Unsalted Butter (1/2 cup, melted) – Forms the crust; ensure it’s melted for easy mixing.
- All-Purpose Flour (1/4 cup + 1 cup for crust) – Provides structure; feel free to try gluten-free flour for a different twist.
- Salt (1/4 teaspoon) – Enhances overall flavor.
For Dusting
- Powdered Sugar (1/4 cup) – Adds a lovely decorative sweetness just before serving.
Step‑by‑Step Instructions for Rhubarb Custard Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven is heating, grab a 9×13-inch baking dish and grease it lightly with butter or non-stick spray to ensure easy removal of the bars later. This step sets the perfect foundation for your delightful Rhubarb Custard Bars.
Step 2: Prepare the Rhubarb Filling
In a medium mixing bowl, combine 2 cups of chopped fresh rhubarb with 1/2 cup of granulated sugar, 1/4 cup of all-purpose flour, 1/4 teaspoon of salt, and 1/2 teaspoon of ground cinnamon. Toss everything together until the rhubarb is well coated with the mixture. Set this aside to allow the flavors to meld while you work on the custard.
Step 3: Mix the Custard Ingredients
In a separate bowl, whisk together 1 cup of whole milk, 3 large eggs, and the remaining 1/2 cup of granulated sugar, along with 1 teaspoon of vanilla extract. Continue whisking until the mixture is smooth and creamy, ensuring the eggs are fully combined. This will be the luscious custard that sits atop your rhubarb filling.
Step 4: Make the Crust
To create the crust, mix 1 cup of all-purpose flour with 1/2 cup of melted unsalted butter in a clean bowl. Stir until the mixture resembles coarse crumbs. Press this mix firmly into the bottom of your prepared baking dish to form an even layer. This buttery crust will serve as the perfect support for your filling and custard.
Step 5: Assemble the Bars
Evenly pour the rhubarb mixture over the crust in your baking dish, spreading it out gently. Then, slowly pour the custard mixture on top, allowing it to seep through the rhubarb. This layered approach creates a beautifully textured balance in your Easy Rhubarb Custard Bars.
Step 6: Bake to Perfection
Place the assembled baking dish in the preheated oven and bake for 40-45 minutes. Watch closely for the custard to set and become lightly golden on top. A good indicator that it’s done is a slight jiggle in the center—this means it’s firming up into a creamy delight.
Step 7: Cool and Slice
Once baked, remove your Rhubarb Custard Bars from the oven and let them cool completely in the pan. This cooling period is crucial for achieving clean slices. After about an hour, refrigerate the bars for additional firmness before cutting them into squares for serving.
Step 8: Dust and Serve
Before serving, dust the tops of the bars with 1/4 cup of powdered sugar for an elegant finish. You can serve these delightful bars slightly warm or chilled, perhaps with a dollop of whipped cream or a scoop of ice cream for an extra treat.

Rhubarb Custard Bars Recipe FAQs
What type of rhubarb should I use for these bars?
Absolutely! Fresh rhubarb is ideal for these bars as it provides a delightful tartness that balances the creamy custard. However, if you don’t have fresh rhubarb at hand, frozen rhubarb can definitely be used. Just remember to thaw it completely and drain any excess moisture before adding it to your mixture; this will help maintain the right texture!
How should I store the leftover rhubarb custard bars?
I recommend storing the bars in an airtight container in the refrigerator for up to 3 days. For optimal freshness, make sure they cool completely before sealing them up. That way, they’ll keep their lovely creamy texture and flavor!
Can I freeze rhubarb custard bars?
Absolutely! To freeze your Rhubarb Custard Bars, wrap them tightly in plastic wrap, then place them in a freezer-safe container or bag. They can be stored for up to 3 months. When you’re ready to enjoy, simply thaw them in the refrigerator overnight before serving!
What if my custard doesn’t set properly while baking?
If your custard isn’t setting as it should, this could be due to a couple of factors. First, ensure you’re baking it long enough—sometimes it might need an extra 5-10 minutes. Second, if you’ve added ingredients like extra sugar or fruit, it can cause additional moisture that affects setting. If this happens, let the bars cool completely in the fridge for a firmer texture; chilling often helps the custard to firm up.
Are rhubarb custard bars safe for pets?
While rhubarb is safe for human consumption, it can be toxic to pets, especially cats and dogs. Rhubarb leaves contain oxalic acid, which can be harmful. It’s best to keep these delicious bars out of reach of your furry friends!
Can I make this recipe gluten-free?
Very! You can certainly experiment with gluten-free all-purpose flour in place of regular all-purpose flour for the crust and filling. Just be aware that the texture might vary slightly. I recommend blending it with a little cornstarch for best results, as it often helps gluten-free baked goods achieve a better structure.
