Ingredients You’ll Need
These ingredients are simple but essential, each contributing in its own way to the wonderful taste, texture, and vibrant character of the bars. From the flaky crust to the creamy custard and the fresh rhubarb’s unique tartness, every component plays a star role.
- 2 cups all-purpose flour for crust: Provides the structure and base for a crisp, buttery shell.
- 1/4 cup granulated sugar for crust: Adds a subtle sweetness to balance the tart rhubarb.
- 1 cup cold unsalted butter, cubed: Chilled butter ensures a flaky, tender crust when baked.
- 2 cups granulated sugar for filling: Sweetens the rhubarb custard filling perfectly.
- 7 tablespoons all-purpose flour for filling: Helps thicken and stabilize the custard during baking.
- 1 cup heavy whipping cream for filling: Brings richness and smoothness to the filling.
- 3 large eggs, beaten: Acts as a binding agent and lends a creamy texture to the custard.
- 5 cups fresh or frozen rhubarb, chopped: The star ingredient — tart, vibrant, and full of flavor.
- 6 ounces cream cheese, softened: Adds a tangy, velvety topping to elevate the bars.
- 1/2 cup granulated sugar for topping: Sweetens the cream cheese layer just right.
- 1/2 teaspoon vanilla extract: Infuses the topping with warm, aromatic notes.
- 1 cup heavy whipping cream, whipped: Lightens the cream cheese frosting, making it airy and luscious.
How to Make Rhubarb Custard Bars Recipe
Step 1: Preheat and Prepare the Crust
Start by heating your oven to 350°F (175°C). This step makes sure the oven is ready for the crust to bake evenly. This crust forms the sturdy and buttery base that will hold all those delicious layers, so getting this right sets you up for success.
Step 2: Mix and Press the Crust
Combine the all-purpose flour and sugar for the crust in a large bowl. Using cold, cubed butter, cut it into the flour mixture until it looks like coarse crumbs — this technique ensures a tender, flaky base. Press this crumbly dough evenly into the bottom of an ungreased 9×13-inch baking dish to form a perfect foundation for the custard.
Step 3: Par-Bake the Crust
Bake the crust for 10 minutes just until it sets. This partial baking prevents the crust from becoming soggy once the moist filling is added later. Allow it to cool slightly after taking it out, so the next layer won’t disturb the delicate base.
Step 4: Prepare the Custard Filling
In a separate bowl, whisk together sugar and flour designated for the filling. Stir in heavy cream and beaten eggs, mixing until smooth and velvety. Then, fold in the chopped rhubarb, which will provide tart bursts throughout the sweet custard, brightening each bite beautifully.
Step 5: Assemble and Bake
Pour the luscious rhubarb custard filling over the pre-baked crust, spreading it evenly. Return the pan to the oven and bake for 40 to 45 minutes until the custard is set and rhubarb becomes tender but holds its shape. This timing creates that ideal custardy texture without overcooking.
Step 6: Make the Cream Cheese Topping
While the bars cool completely, beat together softened cream cheese, sugar, and vanilla extract until the mixture is silky smooth. Gently fold in the whipped cream, which lightens the topping to a fluffy, dreamy consistency that complements the tangy custard and crust.
Step 7: Final Assembly and Chill
Spread this luscious cream cheese topping evenly over the cooled bars. Refrigerate the whole dish for at least two hours; this chilling step helps all the flavors meld together beautifully and makes cutting the bars easier.
Step 8: Serve and Enjoy
Once chilled, cut into 24 bars and serve them up cold. These bars are refreshingly cool while still rich and indulgent, making them perfect for any gathering or a special treat just for you.
How to Serve Rhubarb Custard Bars Recipe
Garnishes
Simple garnishes can take your Rhubarb Custard Bars Recipe to the next level. Try a light dusting of powdered sugar to add a frosty touch, or a few fresh mint leaves for color and a hint of herbal freshness. For an extra sweet crunch, sprinkle toasted sliced almonds on top just before serving for a lovely contrast.
Side Dishes
Serve these bars alongside a dollop of whipped cream or a scoop of creamy vanilla ice cream for a classic pairing. A fresh berry salad also complements the tartness of the rhubarb, adding brightness and freshness to every bite. Alternatively, a hot cup of tea or coffee makes a cozy beverage companion that highlights the dessert’s complexity.
Creative Ways to Present
Thinking about presentation? Arrange the bars on a rustic wooden board with edible flowers scattered around for a charming spring-inspired dessert table. Cut the bars into mini squares for bite-sized treats at parties, or stack them with layers of fresh fruit and cream between for a playful dessert parfait.
Make Ahead and Storage
Storing Leftovers
Leftover Rhubarb Custard Bars keep wonderfully in the refrigerator. Store them in an airtight container, where they will stay fresh and moist for up to four days. This makes them perfect for preparing ahead or enjoying as a delightful snack throughout the week.
Freezing
If you want to save some for later, these bars freeze beautifully. Wrap them tightly in plastic wrap and foil to prevent freezer burn. They’ll keep well for up to two months. When ready to enjoy, thaw them overnight in the fridge for the best texture and flavor.
Reheating
While these bars are delicious chilled, if you prefer to serve them warm, gently reheat individual portions in the microwave for about 15 seconds. Be cautious with reheating since too much heat can soften the cream cheese topping. Serve immediately after warming for a comforting treat.
FAQs
Can I use frozen rhubarb in this Rhubarb Custard Bars Recipe?
Absolutely! Frozen rhubarb works great and is a convenient option when fresh isn’t available. Just thaw and drain excess liquid before folding it into your custard filling to prevent the bars from becoming watery.
Is it possible to make these bars gluten-free?
Yes, you can substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup. Ensure your blend contains xanthan gum or another binder to provide the right texture in both the crust and custard filling.
Can I prepare the crust ahead of time?
Yes, you can press and bake the crust a day ahead, then keep it covered at room temperature. This prep step saves time on baking day and ensures the crust is perfectly set for your filling.
What if I don’t have heavy whipping cream?
You can substitute heavy cream with half-and-half or whole milk, but be aware that the filling and topping may be less rich and less creamy. The heavy cream really helps achieve that luxuriously smooth texture in the custard and topping.
How do I get clean, even slices?
Use a sharp knife cleaned between cuts, and make sure the bars are well chilled before slicing. This prevents the custard and topping from sticking and gives you perfectly neat bars every time.
