Rhubarb Custard Bars Ingredients

For the Crust
• Fresh or Frozen Rhubarb – Provides a sweet-tart flavor and moisture; remember to drain frozen rhubarb well to avoid excess liquid.
• All-Purpose Flour – Forms the base of the crust, adding structure; gluten-free flour is a great substitute.
• Sugar – Sweetens both the crust and filling; consider using brown sugar for a richer flavor.
• Butter (cold) – Ensures a flaky texture; for a dairy-free option, vegan butter can be used but regular butter is best.

For the Custard Filling
• Cream – Adds creaminess to the custard; for a lighter version, use a non-dairy cream.
• Eggs – Provide structure and richness; flax eggs can substitute for a vegan-friendly option.

For the Topping
• Cream Cheese – Creates a smooth topping; opt for vegan cream cheese for a dairy-free alternative.
• Whipped Cream – Lightens the cream cheese topping; fold gently to keep it airy and fluffy.

Step‑by‑Step Instructions for Rhubarb Custard Bars

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C) to create the perfect baking environment for your Rhubarb Custard Bars. This step is essential for ensuring even cooking and helps develop that golden crust. Make sure your oven is properly calibrated, as the right temperature can make a significant difference in the final texture of the crust.

Step 2: Prepare the Crust Mixture
In a large mixing bowl, combine all-purpose flour and sugar. Cut in the cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. This process should take about 3 to 5 minutes. The result will be a crumbly mixture that creates the flaky crust for your rhubarb bars.

Step 3: Press the Crust into the Pan
Evenly press the crumbly crust mixture into a greased 13×9-inch baking pan, ensuring it covers the bottom completely. Use the back of a measuring cup or your fingers for a firm and even layer. Bake the crust in the preheated oven for 10 minutes until it begins to set and turns lightly golden around the edges.

Step 4: Whisk the Custard Filling
While the crust is baking, whisk together the sugar, flour, cream, and eggs in a separate bowl until smooth and well combined. This should take about 2 to 3 minutes, ensuring there are no lumps. Stir in the prepared rhubarb, mixing it gently so the fruit is well distributed in the custard for your delightful Rhubarb Custard Bars.

Step 5: Combine and Bake Again
Once the crust has finished baking, carefully pour the rhubarb custard filling over the warm crust, spreading it evenly. Return the baking pan to the oven and bake for 40 to 45 minutes. You’ll know it’s ready when the custard is set but still has a slight jiggle in the center, signaling its creamy texture.

Step 6: Cool Completely
After baking, remove the pan from the oven and let it cool completely at room temperature, which will take about 1 to 2 hours. Cooling is critical as it allows the custard to set further, making the bars easier to slice and serve later.

Step 7: Make the Cream Cheese Topping
In a mixing bowl, beat the cream cheese with sugar and vanilla until smooth and creamy, about 2 to 3 minutes. Be sure to soften the cream cheese first to achieve the best texture. Gently fold in the whipped cream until the mixture is airy and well blended, which will lighten the topping for your Rhubarb Custard Bars.

Step 8: Spread the Topping and Chill
Once the bars have cooled, spread the cream cheese topping evenly over the custard layer using a spatula. Cover the baking pan with plastic wrap and refrigerate the bars until fully chilled, ideally for at least 2 hours. This chilling step enhances the flavors and helps to firm up the topping for easier slicing.

Step 9: Slice and Serve
Finally, cut the Rhubarb Custard Bars into squares or rectangles for serving. Enjoy them chilled, and consider pairing with a scoop of vanilla ice cream or a hot beverage for a delightful treat. These beautifully layered bars are sure to impress and bring comfort to anyone who tastes them!

How to Store and Freeze Rhubarb Custard Bars

Fridge: Store your Rhubarb Custard Bars in an airtight container in the refrigerator for up to 5 days. This keeps them fresh while the flavors continue to meld.

Freezer: For longer storage, wrap the bars well in plastic wrap and aluminum foil, then place them in the freezer for up to 2 months. Thaw overnight in the fridge before serving.

Make-Ahead: You can prepare the crust and filling a day in advance. Just remember to add the topping right before serving for the best texture.

Reheating: While these bars are best served chilled, if you want a warm treat, gently reheat them in the oven at a low temperature, ensuring not to overbake.

Expert Tips for Rhubarb Custard Bars

Proper Drainage: Ensure frozen rhubarb is thoroughly drained to avoid a soggy filling. This will keep your Rhubarb Custard Bars perfectly balanced.
Watch the Bake Time: Keep an eye on your bars while baking; overbaking will yield a tough custard. A slight jiggle in the center is a sign they are ready.
Room Temperature Cream Cheese: For a smooth topping without lumps, make sure your cream cheese is at room temperature before mixing. This creates a delightful creamy layer.
Fold Gently: When adding whipped cream to the cream cheese, fold it in carefully to maintain airiness. This is key to a light and fluffy topping.
Pre-Chill for Slicing: After refrigerating, let the bars sit for a short time at room temperature before slicing. This helps in achieving clean cuts without crumbling.

Make Ahead Options

These Moist Rhubarb Custard Bars are a fantastic choice for meal prep, allowing you to enjoy delightful desserts with minimal weekday effort! You can prepare the crust and custard filling up to 24 hours in advance. Simply bake the crust and let it cool before adding the filling. To maintain quality, refrigerate the crust wrapped in plastic wrap to prevent dryness. Once you’re ready to serve, pour the custard filling over the crust and bake as directed. For the topping, prepare the cream cheese mixture and refrigerate it until you’re ready to finish your bars by spreading it on top after the custard has set. This way, the bars stay fresh and delicious, making dessert time a breeze!

Rhubarb Custard Bars Recipe FAQs

How do I choose the right rhubarb for my bars?
Absolutely! Look for rhubarb stalks that are firm and vibrant in color, typically a mix of pink and green. Avoid any stalks that are limp or have dark spots all over, as this indicates ripeness loss. If you’re using frozen rhubarb, ensure it’s thawed completely and drained well to prevent excess liquid from making your custard soggy.

How should I store my Rhubarb Custard Bars?
To keep these tasty treats fresh, store them in an airtight container in the refrigerator for up to 5 days. This helps the flavors blend beautifully while maintaining their moist texture. If you notice any condensation, simply air it out a bit before sealing to prevent sogginess.

Can I freeze Rhubarb Custard Bars?
Absolutely! For freezing, I recommend omitting the whipped cream topping first. Wrap the bars tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. They can be frozen for up to 2 months. When you’re ready to enjoy them again, thaw them overnight in the fridge and then add the fresh topping before serving.

I baked my bars for the recommended time, but they’re still wobbly in the middle. Is that normal?
Very much so! When baking, look for a slight jiggle in the center; it means your custard is perfectly set while keeping that delightful creaminess. If it seems overly liquid, however, you may need to bake a bit longer, checking every 5 minutes until it’s cooked through. Just be vigilant to avoid overbaking, which could lead to a tough texture.

Are these bars suitable for gluten-free diets?
Yes! You can easily adapt this recipe by substituting all-purpose flour with a gluten-free flour blend. Just ensure that the blend you choose is designed for baking, as it maintains the structure required for a good crust. This lets everyone enjoy delicious Rhubarb Custard Bars without worry!

What about allergies? Can I make these bars vegan?
Of course! To cater to vegan diets, replace the eggs with flax eggs (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water equals one egg) and use vegan butter and cream cheese. You can also swap the cream with a non-dairy alternative. This way, everyone can savor the flavors without compromise.
