Step‑by‑Step Instructions for Rhubarb Custard Bars
Step 1: Prepare the Crust
Preheat your oven to 350°F (175°C). In a mixing bowl, combine flour and sugar, then cut in cold butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Press this crumbly mixture firmly into the bottom of a greased 9×13-inch baking dish. Bake the crust for about 10 minutes, or until it’s lightly golden, then remove it from the oven to cool slightly.
Step 2: Make the Custard
In a separate bowl, whisk together the sugar, flour, and salt until blended. In another bowl, beat the eggs before adding the heavy cream, whisking until smooth. Combine the wet and dry ingredients gently, ensuring there are no lumps, and fold in the diced rhubarb. The mixture will be creamy and thick, ready to pour over the pre-baked crust.
Step 3: Bake the Custard
Carefully pour the custard mixture over the crust, spreading it evenly with a spatula. Bake in the preheated oven for 40-45 minutes. The custard should be set around the edges but still slightly jiggly in the center—this indicates it’s perfectly baked. Once done, remove it from the oven and allow it to cool at room temperature.
Step 4: Prepare the Topping
While the custard cools, beat together cream cheese, sugar, and vanilla extract in a mixing bowl until the mixture is light and fluffy. Take your time to ensure the cream cheese is well incorporated, creating a smooth texture. Once fluffy, gently fold in the whipped cream to maintain its lightness, creating a creamy and luscious topping for your Rhubarb Custard Bars.
Step 5: Assemble and Chill
Once the custard layer is completely cool, spread the cream cheese topping evenly over the surface using a spatula. Cover the dish with plastic wrap or aluminum foil and refrigerate for 2-3 hours, allowing the flavors to meld and the layers to set. This chilling step enhances both texture and taste, leading to delightful Rhubarb Custard Bars that are ready to be sliced.
Step 6: Slice and Serve
After chilling, remove the dessert from the refrigerator. For cleaner cuts, use a sharp knife, wiping it between slices to avoid any mess. Cut the bars into squares, and serve them chilled. Enjoy the refreshing, creamy blend of flavors as you share these delightful Rhubarb Custard Bars at your next gathering!
Make Ahead Options
These Rhubarb Custard Bars are perfect for busy home cooks looking to save time! You can prepare the crust (step 1) up to 24 hours in advance, simply cover and refrigerate it after baking. The custard filling (step 2) can also be made ahead and stored in the refrigerator, tightly covered, for up to 3 days. To maintain quality, avoid pouring the custard over the crust until you’re ready to bake (step 3). When it’s time to enjoy, pour the custard over the chilled crust and bake as directed. Finish with the fluffy topping (steps 4-5) once cooled. This makes for a refreshing dessert that’s just as delicious with minimal effort!
Expert Tips for Rhubarb Custard Bars

Rhubarb Custard Bars Recipe FAQs
How do I select ripe rhubarb for my bars?
Absolutely! When selecting rhubarb, look for firm stalks with vibrant coloring—preferably a deep pink or red hue—indicating sweetness. Avoid any stalks that are wilted or show dark spots all over, as these are signs of age or spoilage.

What should I do if my custard is not setting properly?
Very good question! If your custard isn’t setting, it’s often due to underbaking. Ensure it bakes until it is slightly jiggly in the center; it will firm up while cooling. If you’re unsure, you can use a toothpick to check the edges—if they come out clean, you’re good to go!
Are there any dietary considerations I should keep in mind?
Yes, definitely! For those with dietary restrictions, you can create a vegan version of these Rhubarb Custard Bars by using flax eggs (1 tbsp flaxseed meal + 2.5 tbsp water per egg) instead of regular eggs.
