Strawberry Rhubarb Custard Dessert Ingredients
For the Crust
- Flour – Structural base for the crust; gluten-free flour can work as a substitute.
- Powdered Sugar – Adds sweetness to the crust; granulated sugar will change the texture slightly.

- Sugar – Sweetens both fruit and custard layers; adjust based on how tart your rhubarb is.
For the Custard
- Flour (Custard) – Thickens the custard layer for creaminess; all-purpose or cake flour yields the best results.

- Eggs – Provides structure and creaminess; beat until fully combined for the best texture.
For the Topping
- Whipped Cream – Optional garnish for extra creaminess and decoration; a delightful touch for serving.

Step‑by‑Step Instructions for Strawberry Rhubarb Custard Dessert
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that when your crust goes in, it bakes evenly and becomes perfectly golden. As the oven warms up, gather your baking equipment, including a 9×13-inch pan, mixing bowls, and a whisk.
Step 2: Prepare the Crust
In a large mixing bowl, combine flour, powdered sugar, and salt until well mixed. Cut in cold cubed butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. This creates a lovely flaky texture for your Strawberry Rhubarb Custard Dessert.
Step 3: Bake the Crust
Press the crumbly mixture evenly into the bottom of the 9×13-inch pan, creating a solid base. Bake in the preheated oven for about 10 minutes or until it turns lightly golden. You’ll know it’s ready when it starts to smell deliciously buttery and looks just a touch brown.
Step 4: Make the Custard Mixture
While the crust bakes, whisk together eggs, sugar, and flour in another bowl until smooth and well combined. Gradually stir in the sour cream, mixing until the custard mixture is velvety. This custard is what brings the Strawberry Rhubarb Custard Dessert its delightful creaminess.
Step 5: Layer the Fruits
Once the crust has cooled slightly, layer the chopped rhubarb and strawberries evenly over the surface. Ensure the fruits are spread out to allow for even cooking and flavor distribution. This step is where the sweet and tart sensations begin to weave together beautifully.
Step 6: Pour the Custard
Carefully pour the custard mixture over the fruit layer, making sure it fills any gaps and clings to the rhubarb and strawberries. The smooth custard will create a delicious fusion as it bakes, enhancing the Strawberry Rhubarb Custard Dessert with creamy goodness.
Step 7: Bake the Dessert
Return the pan to the oven and bake for an additional 40–45 minutes. The custard should be set but still jiggle slightly when you gently shake the pan, and the top should be a lovely, golden hue.
Step 8: Cool and Sprinkle
Once done, remove your dessert from the oven and let it cool completely at room temperature. If desired, sprinkle a mixture of crumbled butter and granulated sugar on top for an added crunchy sweetness.
Step 9: Chill Before Serving
After cooling, refrigerate your Strawberry Rhubarb Custard Dessert for 1-2 hours. This allows the flavors to meld beautifully and creates a refreshing experience when served. The chilling step makes each bite even more delightful!

Make Ahead Options
These Strawberry Rhubarb Custard Desserts are perfect for meal prep enthusiasts! You can prepare the crust and custard filling up to 24 hours in advance. To do this, bake the crust and let it cool completely before wrapping it tightly in plastic wrap and refrigerating. You can also chop the strawberries and rhubarb a day ahead; just store them in an airtight container to keep them fresh. When you’re ready to serve, layer the fruit on the chilled crust, pour the custard mixture on top, and bake as directed. The flavors meld beautifully, ensuring your dessert is just as delicious as if made fresh!

Strawberry Rhubarb Custard Dessert Recipe FAQs
How do I know if my rhubarb is ripe?
Absolutely! Ripe rhubarb should be firm and vibrant in color, ideally a deep pink or red. Avoid stalks with dark spots or a limp texture, as these indicate aging. If you’re unsure, a crisp, bright stalk is your best bet!
What is the best way to store leftovers?
Keep your Strawberry Rhubarb Custard Dessert in an airtight container in the refrigerator for up to 3 days. This helps maintain its creamy texture and delightful flavor. Just remember to place a paper towel inside the container to absorb any excess moisture!
Can I freeze the Strawberry Rhubarb Custard Dessert?
Unfortunately, freezing isn’t recommended for this dessert as the custard may separate upon thawing, impacting the lovely texture. I often suggest enjoying it fresh, but if you must freeze it, make sure it’s cooled completely first, then wrap it tightly in plastic wrap followed by aluminum foil for short-term storage.
What if my custard doesn’t set properly?
If your custard hasn’t set after baking, it likely needs more time in the oven. Check by gently shaking the pan; it should jiggle slightly but not appear liquid. Baking for an additional 5-10 minutes can help achieve that perfect set. Alternatively, if it’s too thin and obviously undercooked, you can also spoon it back into the oven and bake, checking regularly.
Are there any allergies I should consider?
Yes! This recipe contains eggs, dairy, and gluten, which can be problematic for some people. For a gluten-free version, use gluten-free flour for the crust. If you’re catering to someone with a dairy allergy, consider using full-fat coconut milk instead of sour cream in the custard.
How long should I refrigerate the dessert before serving?
I recommend refrigerating your Strawberry Rhubarb Custard Dessert for at least 1-2 hours before serving. Chilling lets the flavors meld beautifully, enhancing the overall taste experience. If you can, chilling it overnight will make it even more delightful!
