Ingredients & Substitutions

Ingredients for Golden Sunset Rhubarb Custard Dream Bars

Crafting these dream bars begins with quality ingredients, though a few thoughtful substitutions can be made if needed.

For the Shortbread Crust:

All-purpose flour, granulated sugar, salt: Standard baking staples. Ensure flour is measured correctly.
Unsalted butter (very cold, cubed): Cold butter is crucial for a flaky, tender shortbread crust. Do not substitute with margarine or softened butter.

For the Rhubarb Layer:

Fresh rhubarb (chopped): Fresh is highly recommended for its texture and vibrant flavor. If using frozen, thaw it completely and drain off excess liquid before measuring and using.
Granulated sugar: Balances the rhubarb’s tartness.
Cornstarch: Acts as a thickening agent for the rhubarb filling.
Fresh lemon juice: Brightens the flavor and enhances the tart notes of the rhubarb.

For the Custard Filling:

Large eggs: Provide structure and richness to the custard.
Granulated sugar, all-purpose flour: Sweetens and thickens the custard.
Whole milk: Contributes to the custard’s creamy texture. For a slightly richer custard, you can use half-and-half.
Pure vanilla extract: Essential for classic custard flavor.
Pinch of salt: Balances the sweetness.

For Garnish (Optional):

Powdered sugar: A light dusting adds an elegant finish.

How to Make This Easy Rhubarb Custard Bar Recipe

Follow these step-by-step instructions to create your own batch of Golden Sunset Rhubarb Custard Dream Bars.

Preheat and Prepare: Set your oven to 375°F (190°C). Lightly grease a 9×13-inch baking pan and line it with parchment paper, allowing an overhang for easy removal later.
Craft the Shortbread Crust: In a large bowl, whisk together flour, sugar, and salt. Cut in the cold, cubed butter using a pastry blender, your fingertips, or a food processor until the mixture resembles coarse crumbs with some pea-sized butter pieces. Press this mixture evenly into the prepared pan.
Blind Bake the Crust: Bake the crust for 15-18 minutes, or until the edges are lightly golden. Let it cool slightly.
Prepare the Rhubarb Layer: In a medium bowl, gently toss the chopped rhubarb with sugar, cornstarch, and lemon juice until well coated. Set aside.
Whip Up the Custard: In another medium bowl, whisk eggs and sugar until light and frothy. Gradually whisk in the flour until smooth. Then, slowly incorporate the milk, vanilla extract, and a pinch of salt.
Assemble the Bars: Evenly spread the rhubarb mixture over the pre-baked crust. Carefully pour the custard filling over the rhubarb, ensuring it covers all the fruit.
Bake to Golden Perfection: Return the pan to the oven and bake for 30-35 minutes, or until the custard is set and the top is lightly golden brown. A slight jiggle in the center is normal; it will firm up as it cools.
Cool and Chill: Remove from the oven and cool completely on a wire rack at room temperature. This crucial step allows the bars to set properly. Once completely cool, transfer to the refrigerator and chill for at least 2 hours, or preferably overnight, before slicing.
Serve: Lift the chilled bars from the pan using the parchment paper overhang. Cut into 16 squares. Dust with powdered sugar just before serving, if desired.

Tips for Success

Chilling is Key: Do not rush the cooling and chilling process. Thoroughly chilled bars not only taste better but also yield perfectly clean, beautiful slices.
Cold Butter for Crust: Ensure your butter for the shortbread is very cold. This prevents it from melting too quickly in the oven, leading to a tender, crumbly crust instead of a tough one.
Adjust Sweetness: Rhubarb can vary in tartness. If your rhubarb is exceptionally tart, you can add an extra tablespoon or two of sugar to the rhubarb layer mixture to achieve your preferred balance.
Flavor Variations: For an extra layer of warmth, consider adding a pinch of ground ginger or cardamom to the rhubarb mixture. Cinnamon also pairs beautifully.
Parchment Paper Overhang: The parchment paper overhang is a lifesaver for easy removal from the pan and clean-up. Don’t skip this step!

Serving Suggestions

These Golden Sunset Rhubarb Custard Dream Bars are a standalone showstopper, but they pair wonderfully with a few simple additions:

Classic Dusting: A light dusting of powdered sugar just before serving adds an elegant touch and a hint of extra sweetness.
With Tea or Coffee: They are the quintessential accompaniment to an afternoon cup of hot tea or a freshly brewed coffee.
A Scoop of Cream: For an extra indulgent treat, serve with a dollop of freshly whipped cream or a small scoop of vanilla bean ice cream.
For Gatherings: Their sturdy, sliceable nature makes them perfect for potlucks, picnics, brunches, or any event where finger desserts are appreciated.

Storage & Reheating

These bars store beautifully, making them an excellent make-ahead dessert:

Storage: Store leftover bars in an airtight container in the refrigerator for up to 3-4 days.
Reheating: These bars are best served chilled, so no reheating is necessary.

FAQ

Q: Can I use frozen rhubarb?

A: Yes, you can. Thaw the frozen rhubarb completely and drain off any excess liquid before chopping and using it in the recipe. This prevents the rhubarb layer from becoming too watery.

Q: How do I know when the custard is set?

A: The custard is set when the edges are firm and lightly golden brown, and the center has only a slight jiggle when gently shaken. It will continue to firm up considerably as it cools.

Q: Why is chilling the bars so important?

A: Chilling is crucial for two main reasons: it allows the custard and rhubarb layers to fully set and firm up, ensuring that the bars hold their shape beautifully. It also makes for much cleaner, more precise slices.

Q: Can I make these bars ahead of time?

A: Absolutely! These bars are ideal for making a day in advance. The flavors meld and the layers set perfectly overnight in the refrigerator, making them even better.
