How to Make Rhubarb Custard Bars
-
Preheat Oven: Begin by setting your oven to 350°F (175°C). While it warms up, grease or line an 8×8-inch baking dish with parchment paper for easy removal later.
-
Prepare Crust: In a large bowl, combine 1.5 cups of flour, 0.5 cup of sugar, softened butter, 1 egg, and a pinch of salt. Mix until the dough forms a cohesive ball.
-
Press Crust: Transfer the dough into the prepared baking dish. Use your fingers or a spatula to evenly spread and press it down to form a smooth crust.
-
Bake Crust: Place the dish in the preheated oven and bake for 15-20 minutes, or until the crust is lightly golden brown and firm to the touch.
-
Prepare Rhubarb: While the crust bakes, chop your rhubarb into small, bite-sized pieces. If you’re using frozen rhubarb, ensure it’s thawed and drained to avoid excess moisture.
-
Make Custard: In another bowl, whisk together 2 eggs, 1 cup of sugar, vanilla extract, 0.25 cup of flour, and baking powder until the mixture is smooth and well-combined.
-
Combine: Gently fold the chopped rhubarb into the custard mixture, ensuring it is evenly distributed throughout.
-
Layer Custard: Pour the custard mixture over the freshly baked crust, spreading it evenly across the surface.
-
Bake Again: Return the dish to the oven and bake for an additional 20-25 minutes, or until the custard is set and lightly golden on top.
-
Cool Completely: Once out of the oven, let the bars cool in the dish for about an hour. Afterwards, refrigerate them until completely chilled.
-
Serve: Cut into squares and, if desired, dust with powdered sugar right before serving for a lovely touch.

Make Ahead Options
These Rhubarb Custard Bars are perfect for busy home cooks looking to save time! You can prepare the crust up to 24 hours in advance; simply store it tightly wrapped in the refrigerator to maintain its freshness. The custard filling can be mixed ahead of time and kept in the fridge for up to 3 days; just be sure to cover it to prevent it from absorbing any odors. When you’re ready to serve, bake the combination once the crust has cooled. The bars will still be just as delicious and creamy, allowing you to enjoy them with minimal effort on a busy day.

Expert Tips for Rhubarb Custard Bars
-
Crust Cooling: Ensure the crust has cooled slightly before adding the custard to prevent it from sinking. A warm crust can lead to a soggier base.
-
Mixing Technique: Avoid over-mixing the custard mixture to maintain a smooth and creamy texture. Gentle folding ensures the custard remains luscious.
-
Rhubarb Prep: If using frozen rhubarb, never skip the thawing and draining step to remove excess moisture. Otherwise, your custard might become too watery.
-
Testing for Doneness: The custard should be set but still have a slight wobble when you pull it out of the oven. Overbaking can lead to a rubbery texture, so keep an eye on it!
-
Serving Tips: For the best taste, serve these Rhubarb Custard Bars chilled. They pair wonderfully with a dollop of whipped cream for a delightful finish.
Rhubarb Custard Bars Recipe FAQs
How can I choose the right rhubarb for my bars?
Absolutely! Look for rhubarb stalks that are firm and crisp, avoiding any with dark spots or mushy areas. The vibrant, ruby-red color indicates ripeness, and when possible, choose stalks that are slender for better tenderness. If shopping for frozen rhubarb, ensure it’s from a reputable brand without excessive ice crystals.
What’s the best way to store leftover Rhubarb Custard Bars?
Very! To keep your Rhubarb Custard Bars fresh, store them in an airtight container in the refrigerator for up to 5 days. This method helps retain their delightful flavor and texture, making them perfect for enjoying later.
Can I freeze Rhubarb Custard Bars?
Absolutely! To freeze your bars, wrap them tightly in plastic wrap followed by aluminum foil or place them in a freezer-safe bag. They should stay fresh for up to 3 months. When you’re ready to enjoy them, thaw in the refrigerator overnight. For a warm treat, pop individual bars in the microwave for 15-20 seconds.
What should I do if my custard doesn’t set properly?
If your custard is still runny after baking, it may need a bit more time in the oven—be sure to check for a slight wobble, indicating it’s just right! If it’s still too liquid, try turning the oven up slightly and give it another 5-10 minutes. Overbaking can lead to a rubbery texture, so keep an eye on it.
Is there any dietary consideration for pets or allergies with this recipe?
Always be cautious! This recipe contains common allergens, including eggs and dairy. For a pet-safe treat, ensure that only humans enjoy these bars, as rhubarb leaves are toxic to dogs and cats. If serving to guests with allergies, consider options like coconut sugar and vegan substitutes to accommodate dietary needs.
